RESUMEN

Across the globe the population is ageing. In addition, older patients are retaining increasing numbers of natural teeth into old age. Therefore, clinicians are faced with the challenges of managing chronic dental diseases, including caries and periodontal disease, alongside replacing missing units. A number of treatment options are available to replace missing teeth for such patients with large numbers currently receiving removable partial dentures. Alternative approaches to treatment should be considered for this population group, including functionally orientated tooth replacement according to the principles of the shortened dental arch concept. In correctly chosen cases, this approach can provide patients with an acceptable, functional and aesthetic reduced dentition. Additionally, evidence suggests that such an approach can significantly reduce the maintenance burden for patients and clinicians which can ultimately deliver a more cost effective solution compared to removable alternatives.

RESUMEN

El objetivo de este estudio es determinar la frecuencia y características del edentulismo parcial y patologías de la articulación temporomandibular en pacientes adultos. Se realizó un estudio observacional y descriptivo de pacientes que concurrieron al Módulo de Odontología Rehabilitadora de la Facultad de Odontología, se seleccionaron 60 pacientes que necesitaban rehabilitación protésica parcial. Las variables estudiadas fueron: edad, sexo, clase de Kennedy, dolor articular, ruidos articulares, restricción y desviación mandibulares. Los datos fueron cargados en una base de datos diseñada a tal efecto, para su análisis estadístico. Del análisis del estudio se observó ausencia parcial de piezas dentarias con mayor frecuencia en el sexo femenino (58%), el 52% correspondieron a la clase I de Kennedy: el 64% en el maxilar inferior, el 17% presentó dolor articular, 28% ruidos articulares, 68% presentó desviación mandibular (siendo lo más frecuente hacia la derecha), y el 42% presentó restricción mandibular leve y solo un n=1, grave. Las pérdidas de las piezas dentarias bilaterales posteriores del maxilar inferior son las de mayor frecuencia asociado a patologías frecuentes del ATM. Partiendo desde la prevención, evitando las pérdidas de piezas dentarias y con una correcta rehabilitación se podrá lograr una buena salud bucodental (AU)


The objective of this study is to determine the frequency and characteristics of partial edentulism and pathologies of the temporomandibular joint in adult patients. An observational and descriptive study of patients who attended the Rehabilitation Dentistry Module of the Faculty of Dentistry was carried out; 60 patients who needed partial prosthetic rehabilitation were selected. The variables studied were age, sex, Kennedy class, joint pain, joint noises, mandibular restriction, and mandibular deviation. The data were loaded into a database designed for this purpose, for statistical analysis. From the analysis of the study, partial absence of teeth was observed with greater frequency in females (58%), 52% corresponded to Kennedy Class I: 64% in the lower jaw, 17% presented joint pain, 28 % joint noises, 68% presented mandibular deviation being the most frequent to the right, 42% presented mild mandibular restriction and only one n = 1 severe. Loss of the posterior bilateral teeth of the lower jaw are the most frequent associated with frequent TMJ pathologies. Starting from prevention, avoiding the loss of teeth and with correct rehabilitation, good oral health can be achieved (AU)

RESUMEN

This article provides a narrative review of the use of dental implants in patients with periodontitis. using clinical examples where possible, consideration is given to the survival and success of implants, peri-implantitis, comparison of periodontally compromised teeth to implants and to treatment planning to help achieve favourable outcomes.
The challenges associated with restoring an edentulous arch or partially dentate dentition with implants where significant alveolar atrophy has occurred can be considerable. Compromised outcomes may be commonplace.
Dental implant treatment is more likely to be successful for those patients who attain and maintain excellent plaque control. Professional support should focus on managing underlying periodontitis prior to commencing implant therapy and providing long term, regular supportive periodontal care upon completion of treatment.

RESUMEN

PURPOSE: The purpose of this study was to determine the influence of mandibular free-end partial edentulism and the wearing of removable partial dentures in the partially edentulous area on the force exerted on maxillary anterior teeth. METHODS: A commercially available jaw model with exchangeable teeth was used. Seven experimental conditions of mandibular free-end edentulism were set up and a distal extension removable partial denture to replace missing posterior teeth was fabricated. Strain gauges were attached to the root surface of the maxillary left central incisor, canine, first premolar and first molar, and the force exerted on them was calculated based on the calibration coefficient. An occlusal load of 49 N was applied and the forces were compared with the Kruskal-Wallis test (P < 0.05). RESULTS: The force exerted on the maxillary anterior teeth increased significantly as the number of remaining teeth decreased. The force exerted on the maxillary anterior teeth decreased significantly with use of a removable partial denture. CONCLUSIONS: When the number of remaining teeth decreases in mandibular free-end partial edentulism, the burden on the maxillary anterior teeth increases. Our findings suggest that for patients with mandibular free-end partial edentulism, wearing a removable partial denture is effective in preserving the remaining teeth by reducing excessive stress.

RESUMEN

Background: The Cone Beam Computed Tomography (CBCT) is currently being used as the most common diagnostic method to evaluate the bone density of the maxilla and the mandible for planning dental implant. Aim: The aim of the study is to check the quantitative alveolar bone density in complete or partial edentulous and dentulous male and female patients among Riyadh sample population in Saudi Arabia. Materials and Methods: The study involved a cross-sectional analysis of 231 consecutive CBCT images of 231 different patients (115 males and 116 females). The scans were of Saudi National patients who were partially or completely edentulous without any bone infections in the maxilla and the mandible. The findings are presented as descriptive statistics and inferential statistics: student -t-test for two group means, ANOVA for three groups, Post-hoc LSD test for multiple comparisons, Levene statistics for testing the homogeneity of variances and a statistical significance at 5% level. Results: Comparison of mean alveolar bone density in maxillae of dentulous male smokers showed a statistically significant difference for bucco-cortical plate and cancellous bone among different regions. In dentulous male nonsmokers, no significant difference was observed for maxillary regions, while in mandibular areas, a statistically significant difference was seen for buccal cortex, palatal cortex, and cancellous bone among different regions. While studying the scans of female dentulous patients, a statistically significant difference was observed in alveolar bone density for all the areas. Conclusion: Evaluation of bone density is an important step in treatment planning and this study was aimed to provide insight into bone density patterns of population in Riyadh, Saudi Arabia. Further similar studies in different populations can help in planning for more efficient treatment outcomes.

RESUMEN

Bone grafting is important to preserve the alveolar bone ridge height and volume for dental implant placement. Even though implant-supported overdentures present highly successful outcomes, it seems that a great number of edentulous individuals have not pursued implant-based rehabilitation. The cost of the treatment is one of the reasons of discrepancy between highly successful therapy and its acceptance. Therefore, the development of biomaterials for bone grafting with comparable characteristics and biological effects than those renowned internationally, is necessary. In addition, domestic manufacture would reduce the high costs in public health arising from the application of these biomaterials in the dental feld. The purpose of this clinical case report is to provide preliminary clinical evidence of the efficacy of a new bovine bone graft in the bone healing process when used for sinus floor elevation. (AU)


El uso de injertos óseos es importante para preservar la altura y el volumen de la cresta alveolar para la colocación de implantes dentales. Si bien las sobredentaduras implanto-soportadas presentan resultados altamente exitosos, la mayoría de las personas desdentadas no han sido rehabilitadas mediante implantes dentales. Uno de los principales motivos por los cuales los pacientes no aceptan este tipo de tratamiento, altamente exitoso, es el elevado costo del mismo. Por ello, es necesario el desarrollo de biomateriales de injerto óseo con características y efectos biológicos comparables a los reconocidos internacionalmente. Asimismo, la fabricación nacional reduciría los altos costos en Salud Pública derivados de la aplicación de estos biomateriales en el campo dental. El objetivo de esta comunicación es presentar un caso clínico a fin de proporcionar evidencia preliminar acerca de la eficacia de un nuevo injerto de hueso bovino en el proceso de cicatrización ósea en el levantamiento del piso del seno maxilar.

RESUMEN

An accurate interocclusal record is essential for the successful delivery of fixed prosthodontic restorations. There are various materials and techniques used to obtain an interocclusal record in order to facilitate mounting of the dental casts on an articulator. The interocclusal record describes the vertical and horizontal relationship of the maxillary and mandibular teeth. In circumstances where the vertical relationship is not supported through a tripod of widely spaced opposing contacts, the interocclusal record will be needed to restore this vertical support to prevent inaccurate mounting. The clinician should understand when an interocclusal record is required and have an awareness of the different materials and techniques available to record an interocclusal registration.

RESUMEN

OBJECTIVES: To compare the use of short implants (≤6 mm) in atrophic posterior maxilla versus longer implants (≥10 mm) with sinus floor elevation. DESIGN: A systematic review and meta-analysis based on randomised controlled trials (RCTs). DATA SOURCES: Electronic searches were conducted in PubMed, Embase and the Cochrane CENTRAL. Retrospective and prospective hand searches were also performed. ELIGIBILITY CRITERIA: RCTs comparing short implants (≤6 mm) and longer implants (≥10 mm) with sinus floor elevation were included. Outcome measures included implant survival (primary outcome), marginal bone loss (MBL), complications and patient satisfaction. DATA EXTRACTION AND SYNTHESIS: Risks of bias in and across studies were evaluated. Meta-analysis, subgroup analysis and sensitivity analysis were undertaken. Quality of evidence was assessed according to Grading of Recommendations Assessment, Development and Evaluation. RESULTS: A total of seven RCTs involving 310 participants were included. No significant difference in survival rate was found for 1-3 years follow-up (RR 1.01, 95% CI 0.97 to 1.04, p=0.74, I²=0%, moderate-quality evidence) or for 3 years or longer follow-up (RR 1.00, 95% CI 0.97 to 1.04, p=0.79, I²=0%, moderate-quality evidence). However, short implants (≤6 mm) showed significantly less MBL in 1-3 years follow-up (MD=-0.13 mm, 95% CI -0.21 to 0.05; p=0.001, I²=87%, low-quality evidence) and in 3 years or longer follow-up (MD=-0.25 mm, 95% CI -0.40 to 0.10; p=0.001, I²=0%, moderate-quality evidence). In addition, short implant (≤6 mm) resulted in fewer postsurgery reaction (RR 0.11, 95% CI 0.14 to 0.31, p<0.001, I²=40%, moderate-quality evidence) and sinus perforation or infection (RR 0.11, 95% CI 0.02 to 0.63, p=0.01, I²=0%, moderate-quality evidence). CONCLUSIONS: For atrophic posterior maxilla, short implants (≤6 mm) are a promising alternative to sinus floor elevation, with comparable survival rate, less MBL and postsurgery reactions. Additional high-quality studies are needed to evaluate the long-term effectiveness of short implants (≤6 mm). TRIAL REGISTERATION NUMBER: The protocol has been registered at PROSPERO (CRD42018103531).

RESUMEN

Combination syndrome (CS) is a dental condition commonly seen in patients with a completely edentulous maxilla and partially edentulous mandible with preserved anterior teeth. Overgrowth of the tuberosities, papillary hyperplasia of palatal mucosa, and decreased occlusal vertical dimension are typically associated with this syndrome. This article describes a case report where the patient was showing initial signs of CS with irritation from an ill-fitting maxillary denture and a loose mandibular acrylic partial denture. As part of the treatment, implant-supported abutments were used to stabilize the maxillary denture, and implants were placed in the posterior mandible to prevent further resorption. The case demonstrates the use of LOCATOR R-Tx® abutments (Zest Dental Solutions) to enable the patient to regain her smile and confidence, showing the versatility of these overpartial abutments.

RESUMEN

Introduction: Edentulism is an irreversible chronic condition that seriously affects the stomatognathic system. Consequently, determining its prevalence may contribute to prioritize preventive and rehabilitative oral health interventions. Objective: To determine the prevalence of partial edentulism according to the Kennedy and Applegate classification in patients attending the Dental Clinic at Universidad San Martín de Porres - Lambayeque Campus, Peru, in the years 2016 and 2017. Materials and methods: A descriptive, retrospective and cross-sectional study was designed. The study comprised 321 clinical records that previously underwent a quality control stage, which included a calibration process (k=0.86). The criteria and rules proposed by Kennedy and Applegate were applied to estimate the prevalence of edentulism in each jaw according to sex; tables of frequency distribution containing percentage results were used. Results: The highest prevalence of partial edentulism in the upper jaw corresponded to Class III (42.4%), followed by Class I (34.6%), and Class II (16.5%). In the lower jaw, the most prevalent were Class I (42.4%), Class III (36.4%), and Class II (15.6%). According to sex, Class III and Class I were the most prevalent in both females and males. Conclusion: Class III and I were the most prevalent in the upper jaw in both females and males; while in the lower jaw, Classes I and III were the most prevalent for both sexes.


El edentulismo se presenta como una alteración irreversible y crónica, que genera consecuencias en el sistema estomatognático, por lo cual es necesario conocer su prevalencia para priorizar intervenciones de salud bucal preventivas y de rehabilitación. Objetivo: Determinar la prevalencia de edentulismo parcial según la clasificación de Kennedy y Applegate en pacientes atendidos en la Clínica Odontológica de la Universidad San Martín de Porres - Filial Lambayeque, en los años 2016 y 2017. Material y Método: Se diseñó un estudio descriptivo, retrospectivo y transversal, con 321 historias clínicas que pasaron previamente por un control de calidad que incluyó un proceso de calibración (k=0.86). Para estimar la prevalencia de edentulismo en cada maxilar y de acuerdo al género, fueron aplicados los criterios y reglas de kennedy y Applegate, utilizando tablas de distribución de frecuencias con resultados porcentuales. Resultados: La mayor prevalencia de edentulismo parcial para maxilar superior corresponde a la Clase III con 42,4%, siguiendo en orden descendente la Clase I con 34.6% y la Clase II con 16.5%. En el maxilar inferior, la más prevalente fue la Clase I con 42,4%, continuando la Clase III con 36.4% y la Clase II con 15.6%. De acuerdo a género, resultaron más prevalentes la Clase III y la Clase I tanto para mujeres como para hombres. Conclusiones: Las clases III y I fueron las más prevalentes en el maxilar superior, tanto para género masculino como femenino; mientras que en el maxilar inferior, fueron las clases I y III las más prevalentes también para ambos géneros.

RESUMEN

The objective of this study was to compare patient-related outcomes of conventional protocols with computer-assisted implant planning and template-guided implant placement (CAIPP) protocols. Partially edentulous patients (N = 73) were assigned to either surgical planning based on two-dimensional radiographs and freehand implant placement (control; n = 26) or using three-dimensional computer-tomography data and implant placement using a tooth-supported surgical guide (test groups T1 [n = 24] and T2 [n = 23]). The two test groups differed from each other in digital data acquisition, software functionality, and the guide-manufacturing process. All surgeries were performed as open-flap procedures. Patient-related outcome measures were evaluated using questionnaires. Statistical tests were performed to investigate differences between treatment groups. Before treatment, 53% of patients in the control group and 83% of patients in the test groups (T1: 88%, T2: 78%) were satisfied with their group allocation. In the control group, 37% of patients favored CAIPP technology, while only 11% in the test groups would have preferred a conventional procedure. After treatment, 50% of patients in the control and 86% in the test groups (T1: 76%, T2: 94%) were satisfied with their allocation. Twenty-one percent of control-group patients favored the CAIPP treatment, while 6% of the test-group patients would have preferred a conventional treatment. The quality-of-life parameters during and after surgery did not show significant differences between groups. More postoperative discomfort was reported after longer and more-complex surgeries including guided bone regeneration and surgeries with two surgical sites. Generally, patients preferred computer-based technologies. No differences in the intra- or postoperative discomfort were observed compared to control protocols. More-extensive surgical procedures negatively affected the intra-and postoperative quality of life, irrespective of the treatment group allocation.

RESUMEN

PURPOSE: To further report and analyze data on the prevalence of implant failures related to age at surgery in partially edentulous jaws. MATERIALS AND METHODS: Altogether, 2915 partially edentulous jaws (Kennedy Class I and II) were consecutively treated with 9167 implants over a 30-year period (1986-2015) in one referral clinic. All implant failures were consecutively recorded and the first event of implant failure was analyzed in relation to patient age at implant surgery. RESULTS: A total of 2453 patients participated in the study. The main observations were a nonlinear, normal distribution association between risk of implant failure and age at surgery with the highest risk in middle-aged patients. The risk for implant failures was significantly higher for middle-aged patients (45-64 years) than for old patients at the time of surgery (P < .05). The overall cumulative survival rates for treated jaws increased consistently from the age group of 40 to 49 years to that of >79 years. However, younger age groups (<40 years) presented a different pattern. Partially edentulous patients included late in the study (2003-2015) presented a more pronounced nonlinear, normal distribution, and the highest risk of implant failure in patients between 50 and 55 years of age at surgery. CONCLUSIONS: An overall nonlinear risk pattern of implant failure was observed, with the highest risk in the middle-aged group at implant surgery. Overall cumulative survival rates were highest in the youngest and oldest age groups at implant surgery, and this pattern became more pronounced in patients included late in the study.

RESUMEN

As our population ages, dentists face challenges in maintaining compromised teeth in aging patients. For the most part, elderly patients (i.e., over 65 years of age) prefer to keep their natural teeth and in some cases, avoid removable dentures altogether. Ideally, patients should not be rendered edentate late in life, as they are unlikely to successfully adapt to the limitations of complete replacement dentures. However, this is not always possible and care should ideally be planned to avoid edentulism, or at least, to carefully manage the transition to the edentate state. In the course of planning care, the dentist needs to recognise the need for age appropriate care, factoring in the impact of the elderly patient's health status and social circumstances. For elderly patients with a compromised dentition, the dentist should try to provide care which is minimally invasive and with as low a burden of maintenance as possible. In this paper, principles of pragmatic care for elderly patients with a compromised dentition will be outlined using clinical cases. Three pathways will be outlined: (i) maintenance of a functional natural dentition using adhesive restorative techniques; (ii) use of overlay prostheses and complete replacement overdentures to manage toothwear and toothloss, complete replacement overdentures, and; (iii) staging a transition to the edentate state using transitional removable partial dentures.

RESUMEN

The study was performed on 21 edentulous patients, treated during the period of 2017 - 2018 at the Surgical Dentistry Department at the Moscow State University of Medicine and Dentistry. The patients underwent the procedures of bone augmentation, dental implant placement, and placement of various design temporary dentures for the periods preceding the placement of the permanent implant-supported dentures. The authors have developed and implemented a medical-prophylactic device - an acrylic partial denture supported by temporary dental implant and Klammer fixation on the existing crowns in front of the edentulous area. The results of the use of the device during the post-operative period were analyzed and compared to those of traditionally designed removable partial devices. The comparative analysis has shown that the medical-prophylactic device is superior to the temporary removable partial dentures and vacuum-formed retainers.

RESUMEN

Suspicious radiological findings in the jaw bone require histopathological examination for the confirmation of a diagnosis. As pathologies in this region are difficult to reach or are in close proximity to relevant anatomical structures, e.g. tooth roots or nerves, they often represent a challenge. Such factors may adversely affect the predictability of the surgical outcome of a biopsy of the osseous tissues. This technical note introduces a novel method for performing a digitally planned, guided biopsy. For this purpose, a cone beam computed tomography scan and an intraoral scan are superimposed using specific planning software. The resulting three-dimensionally printed, tooth-supported drilling template is designed for a trephine biopsy. It allows a precise, minimally invasive approach, with an exact three-dimensional determination of the biopsy location prior to surgery. The risk of devitalization of the neighbouring teeth or possible damage to the nerve structures can be minimized. Furthermore, a small access flap can be sufficient. In summary, the method of bone biopsy presented here allows high precision and greater predictability for biopsy sampling and is minimally invasive for the patient.

RESUMEN

Algorithms for predictable outcomes, or checklists in health care, have been widely supported due to their highly effective outcomes. This article shares "algorithmic roadmaps" to restore single-tooth, partially edentulous, and fully edentulous complex dental implant cases in the patient population. A review of the current literature is presented to provide systematic assessments followed by criteria in a checklist format that allows the surgeon and restorative dentist to determine whether a removable or fixed implant prosthesis is the best patient option. Several cases have been chosen to illustrate the algorithms the authors used to provide an optimized prognosis for surgical/restorative success.

RESUMEN

O registro da relação maxilo-mandibular (RMM) é considerado um passo crítico na confecção de novas próteses totais (PT) pois exige uma precisão técnica capaz de permitir o seu reestabelecimento, de forma confortável e equilibrada com a musculatura oral. O registro é obtido em dois planos, um vertical e outro horizontal: o plano vertical é determinado pela dimensão vertical (DV) e o plano horizontal é estabelecido pela relação cêntrica (RC). Ambos recuperam o suporte labial, altura incisal, linha do sorriso e o corredor bucal de forma natural e personalizada. Esse registro pode ser obtido, iniciando pelo arco inferior, seguindo a fisiologia e anatomia orofacial. Nessa técnica, considerase três princípios fisiológicos: crista alveolar, situada sobre o rebordo alveolar, musculatura relacionada que determinará o corredor bucal e posição lingual do rodete e a linha úmida do lábio inferior que determinará a altura do rodete inferior. Dessa forma, este trabalho tem por objetivo descrever por meio de condução de caso clínico a técnica de restabelecimento da RMM em paciente edentado bimaxilar iniciando pelo arco inferior(AU)


The maxillo-mandibular relation (MMR) is considered a critical step in the preparation of new complete denture (CD), since it requires a technical precision capable of allowing its reestablishment, in a comfortable and balanced way with the oral musculature. The register is obtained in two planes, one vertical and one horizontal: the vertical plane is determined by the vertical dimension (VD) and the horizontal plane is established by the centric relation (CR). Both recover the lip support, incisal height, smile line and buccal corridor in a natural and personalized way. This record can be obtained, beginning with the lower arch, following the physiology and orofacial anatomy. In this technique, three physiological principles are considered: alveolar crest, located on the alveolar ridge, related musculature that will determine the buccal corridor and the lingual position of the wax rim and the humid line of the lower lip which will determine the height of the lower wax rim. Thus, this study aims to describe, by way of conducting a clinical case, the technique of restoration of RMM in a bimaxillary edentulous patient starting with the inferior arch(AU)
