Influence of Immediate Implant Placement and Provisionalization with or without Soft Tissue Augmentation on Hard and Soft Tissues in the Esthetic Zone: A One-Year Retrospective Study.

The purpose of this clinical research was to evaluate peri-implant marginal changes around immediate implants placed either with the application of SCTG or XCM or without soft tissue grafting. A total of 48 patients requiring a single implant-supported restoration in the anterior jaw were selected for inclusion. Three surgical procedures were performed, as follows: type 1 implant with subepithelial connective tissue graft (SCTG), type 1 implant with xenogenic collagen matrix (XCM), and type 1 implant without soft tissue augmentation (NG) (control group). The marginal change of peri-implant soft tissue, facial soft tissue thickness (FSTT), peri-implant health status, esthetics, and patient satisfaction were assessed at one year after surgery. All of the placed implants showed a survival rate of 100%. No significant differences in FSTT were recorded between the SCTG group and the XCM group after treatment (P > 0.05), while the NG group presented a significant difference (P < 0.05). Patients in the NG group lost significantly more in the buccal marginal level than did patients in the SCTG group and those in the XCM group (P < 0.05). The favourable success rate recorded in all groups confirmed immediate tooth replacement as a choice of treatment for a missing anterior single tooth. The NG group presented significant changes of FSTT and buccal marginal level, while XCM constituted a viable alternative to SCTG.

Prosthetic treatment in the adult French population: Prevalence and relation with demographic, socioeconomic and medical characteristics.

BACKGROUND: The aim of this study was to estimate the prevalence of dental prosthetic treatment and to investigate the demographic, social, economic and medical factors associated with the use of fixed and removable dentures in a representative sample of adults living in France. METHODS: The data were obtained from the 2002-2003 Decennial Health Survey, a cross-sectional study of a representative sample of the population living in France, which included 29,679 adults. Information was collected by interview. The variables collected were fixed denture, removable denture, age, gender, number of children, area of residence, nationality, educational attainment, family social status, employment status, annual household income per capita, supplementary insurance, chronic disease, eyesight problems/glasses, hearing problems/hearing aids. Multinomial logistic regression models were used to study the relationship between prosthetic treatment and demographic, socioeconomic and medical characteristics unadjusted, adjusted for age and adjusted for all the characteristics. RESULTS: The prevalence of prosthetic treatment was 34.6% (95% confidence interval (CI): [34.1; 35.2]) for fixed prosthetic dentures and 13.8% (95% CI: [13.4; 14.2]) for removable prosthetic dentures. We showed a gradient between educational attainment and removable dentures; the odds ratio adjusted for all the variables (aOR) associated with no or primary education compared to post-secondary education was 2.56; 95% CI: [2.09; 3.13]. When annual household income per capita was low, subjects were less likely to report fixed dentures (aOR=0.68; 95% CI: [0.62; 0.75]) than those with high annual household income per capita. Individuals without insurance less often reported fixed dentures than those with private insurance. Those reporting chronic disease were less likely to report fixed dentures (aOR=0.87; 95% CI: [0.79; 0.95]) but more likely to report removable dentures (aOR=1.29; 95% CI: [1.17; 1.43]) than those without chronic disease. CONCLUSION: This study reveals social, economic and medical inequalities in fixed and removable prosthetic treatment among adults in France.

Dental Students' Exposure to Periodontal and Implant Placement Surgeries in U.S. Dental Schools.

The aim of this study was to assess nationwide trends in the exposure of dental students to periodontal and implant surgical procedures and to evaluate the potential factors that influence these clinical experiences. A 19-item questionnaire was sent to all 64 directors of predoctoral periodontics in U.S. dental schools. In addition to gathering information on the percentage of students who perform surgical periodontics or implant placement procedures in each program, data on student research groups, periodontics residency programs, and periodontics faculty practices were collected. A total of 33 responses were received, for a response rate of 51.5%. Among the responding institutions, 97% and 45.5% allowed dental students to perform periodontal and dental implant placement surgeries, respectively, although only 26.4% and 15.2% of the dental class ended up performing periodontal and dental implant placement surgeries, respectively. Crown lengthening was the most commonly reported (84.8%) periodontal surgical procedure performed by dental students. A negative correlation was found between the presence of a periodontics residency program and dental students' placing dental implants, while the size of the residency program positively correlated with dental students' placing dental implants. Overall, a wide variation in the exposure of dental students to periodontal and dental implant placement surgical experiences was found. Future surveys should assess clinical procedures performed in other special-ties to gain a broader picture of the experience students are gaining in these areas.

Medication-related osteonecrosis of the jaw associated with implant and regenerative treatments: Systematic review

Background: The aim of this study was to determine if the treatment with bisphosphonates other anti-resorptive and antiangiogenic agents influences the success of regenerative and / or implant treatments. Material and Methods: We reviewed the literature from the last 5 years in the PubMed database, using the following words: "Sinus Floor Augmentation"[Mesh] OR "Dental Implants"[Mesh]) OR "Guided Tissue Regeneration"[Mesh]) AND "Osteonecrosis"[Mesh]. The articles were selected following the inclusion and exclusion criteria and were evaluated using the 22 items of the STROBE declaration. The following PICO clinical question was applied: Does the treatment with agents associated with drug osteonecrosis influence the success of regenerative and implant treatments? Results: The initial search resulted in a total of 27 articles. After eliminating those that did not refer to the topic, were duplicated or did not meet the inclusion / exclusion criteria, a full reading of the articles was made evaluating their methodological quality, obtaining six studies with high methodological quality and two with moderate. Conclusions: The literature regarding this topic is scarce, randomized clinical trials would be necessary to establish protocols relative to implant treatment in patients on antiresorptive treatments. The risk of developing an osteonecrosis associated with the regeneration / implant placement in patients with benign bone diseases is scarce, but it exists and it should not be underestimated. Especially, in the posterior areas of the jaw, if the duration of treatment with BP is greater than 3 years, and if the patient is under therapy with systemic corticosteroids

"Burden of the Triumph:" Burden of peri-implantitis in Indian population - A mathematical model.

CONTEXT: India suffers from a heavy burden of oral diseases. Dental implants (DIs) are prescribed widely by the dental practitioners to replace lost natural teeth. There is no estimate, however, to determine the number of DIs or the number of people with peri-implantitis or the failure of implants after placement. In this modeling study, we attempted to estimate the prevalence of adult Indians who would choose DI in the near future and to calculate the peri-implantitis and failure of DI. MATERIALS AND METHODS: Using the Global Burden of Disease database (2016), the number of dental caries in permanent dentition, periodontal diseases, and edentulism was obtained. Empirical assumptions of patients with anodontia in urban and rural areas who opted for DI, percentage of implants placed, the affordability factors, and mathematical models for DI were formed and executed. Peri-implantitis and survival data from literary evidence were collated. RESULTS: Based on assumptions, 909,643 Indians, (830,231-858,703) would choose DI. Estimated number of peri-implantitis would be 145,543-254,700 and estimated number of failures should be 50,940-79,412 in the near future. CONCLUSIONS: In spite of the high economic challenge and the risks or complications of peri-implantitis, DIs are gaining prominence. It is the dentists' burden to face the renewed challenges due to emerge and provide remedial measures.

Tasa de supervivencia de los implantes dentales de óxido de circonio. Una revisión sistemática y metaanálisis / Survival rate of zirconium oxide dental implants. A systematic review and meta-analysis

Antecedentes. A pesar de que el titanio es un material popular en implantología, su color grisáceo puede dar lugar a problemas estéticos. Por lo tanto, la investigación se ha centrado en la búsqueda de un material para el implante que posea el mismo color del diente, que mejore su apariencia estética, y al mismo tiempo, que sea altamente biocompatible y capaz de soportar las fuerzas presentes en la cavidad oral. Objetivo. Determinar, por medio de una revisión sistemática y un metaanálisis, las tasas de supervivencia de los implantes dentales de óxido de circonio. Material y método. Se realizó una búsqueda de la literatura hasta diciembre del 2015, en las bases de datos biomédicas Pubmed, Scopus, Web of Science y Google Académico. Se definieron previamente los criterios de selección de los estudios que consideraban los implantes dentales de óxido de circonio, con una antigüedad máxima de 5 años, que reportaran tasa de supervivencia, tiempo de seguimiento mayor o igual a un año y un tamaño de muestra mayor o igual a 10 pacientes. Se analizó la calidad metodológica de los estudios por medio de las escalas JADAD y CMQ. Resultados. La estrategia de búsqueda resultó en 13 artículos en los que la tasa de supervivencia global fue del 91,43% con un seguimiento de entre 1 y 5 años. Conclusión. La literatura revisada señala que los implantes dentales de óxido de circonio poseen la misma tasa de supervivencia que los implantes dentales de titanio, sin embargo, se necesitan más investigaciones para recomendar su uso clínico (AU)

Background. Although titanium is a popular material in implantology, its greyish colour can lead to aesthetic problems. Therefore, research has focused on finding a material for implants that has the same colour of the tooth, in order to improve its aesthetic appearance, and at the same time is highly biocompatible and able to withstand the forces present in the oral cavity. Objective. To determine the survival rates of zirconium oxide dental implants, using a systematic review and meta-analysis. Material and methods. A literature search was conducted up to December 2015 in the biomedical databases, PubMed, Scopus, Web of Science, and Google Scholar. The selection criteria of the studies considered to use zirconium oxide dental implants, with a maximum age of 5 years, that reported survival rates, time greater than or equal to one year follow-up, and a sample size equal to or greater than 10 patients. The methodological quality of the studies was analysed using the JADAD and CMQ scales. Results. The search strategy resulted in 13 articles, in which the overall survival rate was 91.43%, with a follow up of between 1 and 5 years. Conclusion. The literature reviewed suggests that zirconium oxide dental implants have the same survival rate than titanium dental implants, however more research is needed to recommend clinical use (AU)

The role of hyperbaric oxygen therapy in the prevention and management of radiation-induced complications of the head and neck - a systematic review of literature.

Radiation therapy for the treatment of head and neck cancer can injure normal tissues and have devastating side effects. Hyperbaric oxygen (HBO) is known to reduce the severity of radiation-induced injury by promoting wound healing. While most of the research in literature has focused on its efficacy in osteonecrosis, HBO has other proven benefits as well. The aim of this review was to identify the various benefits of hyperbaric oxygen therapy in patients who have undergone radiation for head and neck cancer. An electronic database search was carried out to identify relevant articles and selected articles were reviewed in detail. The quality of evidence for each benefit, including preserving salivary gland function, preventing osteonecrosis, dental implant success, and overall quality of life, was evaluated. Evidence showed that HBO was effective in improving subjective symptoms of xerostomia, swallowing, speech and overall quality of life. There was no conclusive evidence to show that HBO improved implant survival, prevented osteonecrosis, or improved salivary gland function. The high costs and accessibility of HBO therapy must be weighed against the potential benefits to each patient.

Masticatory muscle activity evaluation by electromyography in subjects with zygomatic implants

BACKGROUND: Zygomatic implants are an alternative treatment in the rehabilitation of atrophic maxilla to promote stability in the stomatognathic system. The aim of this study was to compare the electromyographic (EMG) activity of masseter and temporalis muscles in controls and in individuals with complete implant-supported dentures anchored in the zygomatic bone. MATERIAL AND METHODS: Fifty-four volunteers of both genders (mean age 52.5 years) were selected and distributed into two groups: Individuals with zygomatic implant (ZIG; n=27) and fully dentate patients (CG; n=27). MyoSystem-BR1 was used to assess masseter and temporalis muscles EMG activity in different mandibular movements: protrusion, clenching, maximal voluntary contraction (MVC) with Parafilm M(R), right and left laterality and chewing (peanuts and raisins). Data was processed, normalized (MVC) and analyzed using the SPSS 21.0. Student t-test (P ≤ 0.05) was used for group comparison. RESULTS: The results were statistically significant (P ≤ 0.05) for protrusion, clenching, right and left laterality and raisin chewing. For the mandibular posture conditions, the ZIG obtained higher EMG activity patterns when compared to CG. For the masticatory performance during chewing of peanuts and raisins, the ZIG showed higher EMG mean values when compared to CG. CONCLUSIONS: The zygomatic implant promoted an active response of the muscle fibers (hyperactivity) during both mandibular posture and chewing conditions, probably due to the absence of periodontal receptors, which play a significant role for preparing a bolus for swallowing

How could multimedia information about dental implant surgery effects patients’ anxiety level?

BACKGROUND: To evaluate the effects of different patient education techniques on patients' anxiety levels before and after dental implant surgery. MATERIAL AND METHODS: Sixty patients were randomized into three groups; each contained 20 patients; [group 1, basic information given verbally, with details of operation and recovery; group 2 (study group), basic information given verbally with details of operative procedures and recovery, and by watching a movie on single implant surgery]; and a control group [basic information given verbally «but it was devoid of the details of the operative procedures and recovery»]. Anxiety levels were assessed using the Spielberger's State-Trait Anxiety Inventory (STAI) and Modified Dental Anxiety Scale (MDAS). Pain was assessed with a visual analog scale (VAS). RESULTS: The most significant changes were observed in the movie group (P < 0.05). Patients who were more anxious also used more analgesic medication. Linear regression analysis showed that female patients had higher levels of anxiety (P < 0.05). CONCLUSIONS: Preoperative multimedia information increases anxiety level

Aesthetic perception of single implants placed in the anterior zone. A cross-sectional study

BACKGROUND: Several aesthetic indexes have been described to assess implant aesthetics. The aim of this study was to compare the aesthetic assessment made by dental professionals and students of single-tooth implants placed in the upper incisors. MATERIAL AND METHODS: A cross-sectional survey study using a subjective questionnaire to assess the aesthetics in 3 implant supported single-tooth cases in the anterior maxilla was performed. The interviewed subjects were divided into 4 groups: dentists with experience in implant treatment, dentists without experience in implants and 3rd and 5th year dental students. The questionnaire consisted of 2 visual analogue scales (VAS) to evaluate aesthetics, the pink esthetic score (PES), the white esthetic score (WES) and the simplified papilla index (PI). RESULTS: One-hundred dentists and one-hundred dental students filled the aesthetic assessment questionnaire. The results showed that the subjects were more critical than reference values, specially concerning prosthetic issues. The differences between groups were more obvious in the case with the best result. On the other hand, few differences were detected in the remaining cases. Regarding soft tissue and crown features, experienced dentists in implant dentistry were the most demanding. Cronbach's Alpha showed values ≥ 0,8 in the questionnaire in every case, which indicates an adequate reliability. CONCLUSIONS: Dentists and dental students have different opinions when assessing aesthetics of single tooth implant supported cases. Experience and area of expertise seem to influence the evaluation of aesthetics in the anterior region

Long-term outcomes of oral rehabilitation with dental implants in HIV-positive patients: A retrospective case series

BACKGROUND: The existing information on oral rehabilitations with dental implants in VIH-positive patients is scarce and of poor quality. Moreover, no long-term follow-up studies are available. Hence, the aims of this study were to describe the long-term survival and success rates of dental implants in a group of HIV-positive patients and to identify the most common postoperative complications, including peri-implant diseases. MATERIAL AND METHODS: A retrospective case series of HIV-positive subjects treated with dental implants at the School of Dentistry of the University of Barcelona (Spain) was studied. Several clinical parameters were registered, including CD4 cell count, viral load and surgical complications. Additionally, the patients were assessed for implant survival and success rates and for the prevalence of peri-implant diseases. A descriptive statistical analysis of the data was performed. RESULTS: Nine participants (57 implants) were included. The patients' median age was 42 years (IQR=13.5 years). The implant survival and success rates were 98.3% and 68.4%, respectively, with a mean follow-up of 77.5 months (SD=16.1 months). The patient-based prevalence of peri-implant mucositis and peri-implantitis were 22.2% and 44.4% respectively at the last appointment. Patients that attended regular periodontal maintenance visits had significantly less mean bone loss than non-compliant patients (1.3 mm and 3.9 mm respectively). CONCLUSIONS: Oral rehabilitation with dental implants in HIV-positive patients seems to provide satisfactory results. In order to reduce the considerably high prevalence of peri-implant diseases, strict maintenance programmes must be implemented

Oral health-related quality of life and implant therapy: A prospective multicenter study of preoperative, intermediate, and posttreatment assessment.

PURPOSE: Loss of teeth is associated with a significant reduction in quality of life. The aim of this prospective multicenter study was to assess the impact of dental implants on oral health-related quality of life (OHRQoL). MATERIAL AND METHODS: Patients with various kinds of indications for dental implants ranging from single-tooth loss to edentulous jaws were included. Quality of life related to dental implants was assessed through the Oral Health Impact Profile (OHIP-G 21), which has a score from 0 to 20 in healthy patients. RESULTS: In total, 8689 patients from 17 centers from 2009 to 2014 were enrolled in the study. The sex distribution was almost even (53.3% men, 46.7% women). The most frequent indications for the insertion of dental implants were free-end gaps (30.6%) and posterior single-tooth gaps (27%). In all, 12.4% of patients had an edentulous jaw. For all indications, patients reported significant changes in mean OHIP scores after prosthetic reconstruction. The most significant improvements in the OHIP score occurred in the groups of patients with edentulous jaws (pretreatment score: 42.3) after prosthodontic reconstruction (score: 24.8) and in the patient group with an anterior single-tooth gap (pretreatment score: 36.4) after prosthodontic reconstruction (score: 24.8). CONCLUSION: The insertion of dental implants and prosthodontic rehabilitation led to an improved OHRQoL for patients with all indications for dental implants, with the most significant improvements in patients with edentulous jaws and anterior single-tooth gaps.

Eficácia de um agente cimentante e antisséptico no controle bacteriano nas conexões dos implantes / Efficacy of a cementing and antiseptic agent in preventing contamination and bacterial flow at the dental implant connection

Objetivo: avaliar a eficácia de um antisséptico de longa duração no controle microbiano dos espaços entre o implante e o parafuso de cobertura (PC), pela contagem das unidades formadoras de colônias (UFCs) no ato da reabertura. Material e métodos: foram selecionados 70 sítios em 17 pacientes, para instalação de implantes dentais, e divididos aleatoriamente em dois grupos. No grupo experimental (n=35), o antisséptico foi aplicado na rosca do PC, imediatamente antes de sua instalação. No grupo-controle, a instalação do PC foi feita sem o antisséptico. A reabertura foi realizada após seis meses e os PCs foram removidos e armazenados em frascos assépticos contendo solução salina. Cada amostra foi centrifugada, diluída seriadamente até 10-10, semeada e encubada em microaerofi lia para a cultura de UFCs. Após a contagem, as análises estatísticas comparativas foram feitas pelo teste de Kruskal-Wallis (p < 0,05). Resultados: o grupo-controle apresentou média de 7,18 x 107 UFC/ml, enquanto no experimental a média foi de 2,12 x 105 UFC/ml. O crescimento bacteriano foi significativamente menor no grupo experimental (p=0,0003). Conclusão: o antisséptico reduziu signifi cativamente o crescimento bacteriano entre implante e parafuso de cobertura, tendo sido eficaz no controle microbiano destes espaços.

Objective: to evaluate the effi cacy of a long-term antiseptic in bacterial control of the spaces between the implant and the cover screw (PC), by counting colony-forming units (UFC) at the time of the re-entry surgery. Material and methods: seventy sites for implant placement were selected in 17 patients referred for dental implants, and divided randomly into two groups. In the experimental group (n=35), the antiseptic was applied on the thread of the PC immediately before installation. In the control group, the PC was installed with no antiseptic. The re-entry was performed after six months, the PCs removed and stored in asseptic recipients containing saline solution. Each sample was centrifuged, diluted serially up to 10-10, seeded and incubated in microaerophilic conditions for CFU culture. After counting, statistical comparative analyzes were performed by Kruskal-Wallis test (p < 0.05). Results: the control group had a mean of 7.18 x 107 CFU/mL, while the experimental average was 2.12 x 105 CFU/mL. Bacterial growth was significantly lower in the experimental group (p=0.0003). Conclusion: the antiseptic reduced, significantly, the bacterial contamination in the spaces between the implant and the cover screw, being effective in the microbial control of those spaces.

Implantes de diâmetros reduzidos extrafinos em áreas estéticas: relato de caso / Superfine narrow diameter implants in aesthetic zones: case report

As regiões que devam ser reabilitadas com implantes, quando pobres em volume ósseo, podem inviabilizar a utilização de implantes de diâmetro padrão. Quando, por alguma razão, as técnicas de regeneração óssea coadjuvantes não são as escolhas desejáveis, os implantes de diâmetro reduzido extrafinos podem ser uma alternativa satisfatória, inclusive em áreas estéticas. O objetivo do presente artigo foi descrever o emprego dessa solução mediante o relato de um caso clínico, no qual foram empregados dois implantes de diâmetro reduzido extrafinos, para a reabilitação estética imediata das áreas de incisivos laterais superiores com espessura óssea reduzida, em uma paciente cuja condição (Síndrome de Down) não permitiria o emprego de técnicas regenerativas sem anestesia geral (AU).

The regions to be rehabilitated with implants, when having poor bone volume, may hinder the use of standard diameter implants. When for some reason, the supporting bone regeneration techniques are not desirable choices, narrow superfine implants can be a satisfactory alternative, including aesthetic zones. The goal of this article was to describe the use of this solution through a clinical case report in which two superfine narrow diameter implants were used for the immediate aesthetic rehabilitation of upper lateral incisors with reduced bone thickness in a patient whose condition (Down Syndrome) would not allow the use of regenerative techniques without general anesthesia (AU).

O uso de gengiva artificial para melhorar a estética de dentes naturais e implantes / The use of artificial gum to improve aesthetic of natural teeth and implants

Apesar dos grandes esforços feitos para alcançar o resultado estético das restaurações implantossuportadas, complicações podem ocorrer. Para o tratamento destas complicações, correções podem ser necessárias, sendo elas cirúrgicas (reconstrução óssea e do tecido mole) ou protéticas. Quando muito extensas e diante da recusa dos pacientes pelos procedimentos cirúrgicos, a alternativa para estas situações clínicas é a prótese gengival. Esta pode ser fixa ou removível e feita a partir de acrílico, resinas e materiais à base de porcelana. Pode ser utilizada para reconstruir proteticamente regiões onde houve perda de estrutura óssea e/ou de tecido mole, para minimizar defeitos estéticos de exposição da cinta metálica em componentes angulados, e em casos de doença periodontal com migração apical da margem gengival, provocando sensibilidade, dificuldades fonéticas por escape do ar e espaços negros na região de dentes anteriores. Compreender os métodos usados para incorporar próteses gengivais em tratamento protético é vital para assegurar que aos pacientes sejam oferecidas todas as possíveis opções no início do planejamento do tratamento. É procedimento de baixo custo e confecção, ao alcance de qualquer laboratório e facilmente aceito pelos pacientes pela facilidade de manutenção (AU)

Despite the great efforts to achieve good aesthetic results of dental implants restorations, complications can occur. For the treatment of these complications, corrections may be necessary. This corrections can be surgical (bone and soft tissue reconstruction) or prosthetic. When major reconstructions are required and the patient refuses to submit to surgical procedures, the prosthetic gingival reconstruction is an alternative. This prosthesis can be fixed or removable and made of acrylic, resin materials and porcelain. It can be used to reconstruct prosthetic regions with bone and/or soft tissue loss, to minimize metal exposure of angulated abutments in aesthetic regions, and in cases of periodontal disease and apical migration of gingival margin, causing sensitivity, phonetic problems due to air escape, and black spaces in the region of anterior teeth. Understanding the methods used to incorporate gingival prostheses in prosthetic treatments is vital to ensure that patients all possible options are presented to the patient at the beginning of treatment planning. It is a low cost procedure that can be manufactured by any laboratory and easily accepted by patients due to its simple maintenance (AU)

The importance of implantology in the undergraduate program and the experience of an institution / La importancia de la implantología en el programa de pregrado y la experiencia de una institución

The aim of this study was to identify the teaching discipline of Implantology in all the dental schools in Brazil and report the 9 years of experience after the induction of this material in a teaching institution. The universal sample consisted of dental schools accredited by the Federal Council of Dentistry (n= 198). The results were analyzed with the SPSS Statistics IBM program. It was observed that the discipline of Implantology is offered by 26.9% of the institutions in the fourth year of the undergraduate course. The format of the lessons is 83.3% theory and laboratory. It is also important to note that 2.5% of the institutions do not offer Implantology as a discipline, and in 33.3% of the cases, it appears as a mandatory subject. In order to report the experience, it was observed that the patients' quality of life increased after implantation, and 69.8% classified mastication as excellent after placement of the implant element. Thus, the format offered in the discipline of Implantology proved quite variable according to each institution. The high levels of satisfaction with dental implants and the increased demand for this procedure allowed a suggestion for a possible standardization of the discipline.

El objetivo fue identificar la enseñanza de la disciplina de Implantología en todas las escuelas de odontología en Brasil y reportar los 9 años de experiencia después del inicio de esta disciplina en una institución. La muestra consistió en escuelas de odontologia acreditadas por el Consejo Federal de Odontología (n= 198). Los resultados fueron analizados con el paquete estadístico SPSS IBM. La disciplina de Implantología es ofrecida por el 26,9% de las instituciones en el cuarto año del pregrado en Odontología. El formato de clases fue teórico y práctico (83,3%). En 2,5% de las instituciones no se ofrece Implantología como disciplina, y en 33,3% de los casos, aparece como una disciplina obligatoria. Con el fin de informar la experiencia de una institución, se observó que la calidad de vida de los pacientes aumentó después de la colocación de implantes y 69,8% clasificaron su masticación como excelente después de la colocación de implantes. El formato que se ofrece en la disciplina de Implantología se mostró muy variable en cada institución. Los altos niveles de satisfacción con los implantes dentales y el aumento de la demanda de este procedimiento permite una sugerir una posible normalización de la disciplina.

Asistencia del paciente a las citas de mantenimiento con implantes. Estudio de cohorte retrospective / Patient´s attendance to implant maintenance appointments. A retrospective cohort study

Introducción. El mantenimiento de los implantes dentales se realiza mediante una adecuada higiene oral del paciente para controlar, la placa bacteriana y mediante el establecimiento de las revisiones profesionales periódicas. Objetivo. Determinar si los pacientes portadores de implantes acuden a las revisiones periódicas recomendadas por el profesional tras la instalación de la prótesis. Material y método. Se llevó a cabo un estudio de cohorte retrospectivo de los pacientes de uno de los centros del Máster de Cirugía Bucal e Implantología del hospital Virgen de la Paloma, entre los años 2006 y 2013 donde se han recopilado las historias clínicas. Se realizó un estudio estadístico descriptivo inferencial para hallar el riesgo relativo, utilizando el programa Epidat 3.1. Resultados. En el estudio se evaluaron 414 historias clínicas, descartándose 25 por estar incompletas. De las 389 historias clínicas restantes, 212 eran mujeres y 177 hombres. Las hombres acudieron con mayor frecuencia al mantenimiento de los implantes, aunque ya en el primer año, la asistencia a las revisiones cae al 42%.Se obtuvo un riesgo relativo de 0,92 a los doce meses. Discusión. En la realización del presente estudio, cabe destacar la falta de trabajos al respecto. Además, se deben mencionar dos posibles sesgos: datos incompletos en las historias clínicas y que los implantes incluidos en este estudio fueron colocados por estudiantes de postgrado. Conclusión. La mayoría de los pacientes estudiados no acuden a las revisiones periódicas establecidas, por lo que se hace necesario establecer programas de mantenimiento y de educación al paciente (AU)

Introduction. Dental implant maintenance is carried with an adequate oral hygiene and regular checks up with the aim to control dental plaque. Objective. Analyze patient attendance to the recommended implants checks up. Materials and Methods. Aretrospective cohort study was carried out of all patients in one of the service centers of the Master of Oral Surgery and Implantology Virgen de la Palomahospital, between the years 2006- 2013. Descriptive inferential statistical analysis to find the relative risk was performed using the program Epidat 3.1. Results. The study evaluated 219 medical histories, 25 were rejected as incomplete. Of the remaining 389 medical records, 212 were women and 177 men. Men most often attend to the maintenance of implants, although in the first year, attendance at the reviews falls to 42%. A relative risk of 0.92 for the twelve months was obtained. Discussion. In the present study included the lack of work thereon. In addition, we should mention two possible biases: incomplete medical history and implants included in this study were placed by graduate students enrolled. Conclusion. Most of the patients do not come to set periodic review, so it is necessary to establish maintenance programs and patient education (AU)

An Assessment of the Risk of Bias in Randomized Controlled Trial Reports Published in Prosthodontic and Implant Dentistry Journals.

PURPOSE: The objective of this study was to assess the risk of bias of randomized controlled trials (RCTs) published in prosthodontic and implant dentistry journals. MATERIALS AND METHODS: The last 30 issues of 9 journals in the field of prosthodontic and implant dentistry (Clinical Implant Dentistry and Related Research, Clinical Oral Implants Research, Implant Dentistry, International Journal of Oral & Maxillofacial Implants, International Journal of Periodontics and Restorative Dentistry, International Journal of Prosthodontics, Journal of Dentistry, Journal of Oral Rehabilitation, and Journal of Prosthetic Dentistry) were hand-searched for RCTs. Risk of bias was assessed using the Cochrane Collaboration's risk of bias tool and analyzed descriptively. RESULTS: From the 3,667 articles screened, a total of 147 RCTs were identified and included. The number of published RCTs increased with time. The overall distribution of a high risk of bias assessment varied across the domains of the Cochrane risk of bias tool: 8% for random sequence generation, 18% for allocation concealment, 41% for masking, 47% for blinding of outcome assessment, 7% for incomplete outcome data, 12% for selective reporting, and 41% for other biases. CONCLUSION: The distribution of high risk of bias for RCTs published in the selected prosthodontic and implant dentistry journals varied among journals and ranged from 8% to 47%, which can be considered as substantial.

Publication of statistically significant research findings in prosthodontics & implant dentistry in the context of other dental specialties.

OBJECTIVES: To assess the hypothesis that there is excessive reporting of statistically significant studies published in prosthodontic and implantology journals, which could indicate selective publication. METHODS: The last 30 issues of 9 journals in prosthodontics and implant dentistry were hand-searched for articles with statistical analyses. The percentages of significant and non-significant results were tabulated by parameter of interest. Univariable/multivariable logistic regression analyses were applied to identify possible predictors of reporting statistically significance findings. The results of this study were compared with similar studies in dentistry with random-effects meta-analyses. RESULTS: From the 2323 included studies 71% of them reported statistically significant results, with the significant results ranging from 47% to 86%. Multivariable modeling identified that geographical area and involvement of statistician were predictors of statistically significant results. Compared to interventional studies, the odds that in vitro and observational studies would report statistically significant results was increased by 1.20 times (OR: 2.20, 95% CI: 1.66-2.92) and 0.35 times (OR: 1.35, 95% CI: 1.05-1.73), respectively. The probability of statistically significant results from randomized controlled trials was significantly lower compared to various study designs (difference: 30%, 95% CI: 11-49%). Likewise the probability of statistically significant results in prosthodontics and implant dentistry was lower compared to other dental specialties, but this result did not reach statistical significant (P>0.05). CONCLUSIONS: The majority of studies identified in the fields of prosthodontics and implant dentistry presented statistically significant results. The same trend existed in publications of other specialties in dentistry.
