RESUMEN

PURPOSE: To investigate the impact of high-speed sintering and artificial aging on the fracture load of three-unit zirconia fixed dental prostheses (FDPs). MATERIALS AND METHODS: Three-unit FDPs manufactured from 3Y-TZP (Ceramill Zolid, Amann Girrbach) and 4Y-TZP (Ceramill Zolid HT+, Amann Girrbach; N = 128, n = 64/group) were sintered at 1,580°C (high-speed sintering) or at 1,450°C (control group; n = 32/subgroup). Specimens were bonded to steel abutment models using Multilink Automix (Ivoclar Vivadent), and fracture load was examined without (n = 16/subgroup) and with artificial aging (6,000 thermocycles [5°C/55°C] and 1,200,000 chewing cycles [50 N]; n = 16/subgroup). Univariate analysis of variance, unpaired t test, and Weibull modulus were computed (P < .05). RESULTS: Sintering protocol (P = .944), artificial aging (P = .630), and zirconia material (P = .445) did not show an influence on the fracture load of three-unit FDPs. High-speed sintering led to superior Weibull modulus results for artificially aged 4Y-TZP specimens, while all other groups showed values in the same range. CONCLUSION: The present study shows promising results for the novel high-speed sintering protocol, as it led to comparable fracture load and similar, or even superior, Weibull modulus results compared to the control group. The 4Y-TZP material presented fracture load results similar to the tried-and-tested 3Y-TZP. Artificial aging did not influence zirconia's resistance to fracture for either 3Y-TZP or 4Y-TZP.

RESUMEN

Dental prosthesis laboratories (DPLs) are among the workplaces where predominantly manual production takes place. In such working environments, during the manual manufacturing process, which involves fine smoothing and polishing of dental prostheses, fine particulate matter is released into the ambient air. In this study, the particulate matter (PM) concentrations and elemental content of the fine particles in the working ambient air were identified in six DPLs in Kocaeli, Turkey. PM2.5 mass concentrations, measured in all the DPLs, ranged between 80.8 and 1645 µg/m3 (mean 414 ± 406). As a result of the analyses performed with an ICP-MS device (Perkin Elmer Elan®DRC-e), trace elements of Be, Cd, Hg, and, notably, Co, Cr, Mo, and Ni were found. The researchers calculated the excess lifetime cancer risks and total hazard indexes. The average total cancer risk for all the DPLs was 8 × 10-3, which is higher than the acceptable limit of 1.0 × 10-6, and the total hazard index was 187, which is greater than the acceptable limit of 1.0. Considering these high-level risks, the study concluded that there is a need for new production methods, and strict application of occupational health and safety measures, to reduce the fine particle exposure of the workers in the laboratories. In addition, there are prescribed limit values for particulate matter only for respirable particles in working environments. The establishment of limit values, especially for PM2.5 concentrations, is important for the protection of the health of the employees.

RESUMEN

The aim of this study was to compare the accuracy and precision of 3D printers used to obtain models of fixed dental prostheses. A fixed dental prosthesis preparation was scanned and reproduced by four 3D printers: RapidShape P40, Asiga MAX, Varseo, and Photon. The impressions were scanned again, and the dataset was compared to the original dataset. Mean discrepancies (µm) were 52.97±20.48 (RapidShape P40), 68.27±43.53 (Asiga MAX), 62.22±56.21 (Varseo), and 80.03±28.67 (Photon). There was no difference (p=0.314) in accuracy; however, the precision differed (p=0.015) among the 3D printers. The printers had distinct precision but did not differ in accuracy.

RESUMEN

AIM: Despite the expanding implementation of intraoral scanning (IOS) devices, indirect digitization of conventional impressions or casts still represents the primary access to CAD/CAM. The aim of this study was to evaluate the accuracy of data acquired from impression scans and cast scans with respect to impression material and type of cast used. MATERIALS AND METHODS: A standardized titanium model for a four-unit fixed dental prosthesis (FDP) served as a testing model. Industrial computed tomography (CT) was applied, generating a reference data set. Four different impression materials were utilized (n = 12 per material): 1) Impregum Penta (polyether/group PE); 2) Imprint 4 Penta Super Quick Heavy + Super Quick Light (polyvinyl siloxane (PVS)/group PVS-I); 3) Dimension Penta H Quick + L (PVS/group PVS-D); and 4) Imprint 4 Preliminary Penta Super Quick (PVS/group PVS-P). Data were obtained from three different model situations, ie, impressions (group IMP), unsectioned plaster casts (group UNSEC), and sectioned casts (group SEC). The surfaces were digitized three times each using a laboratory scanner. The resulting test data were superposed with the reference data using a best-fit algorithm to evaluate accuracy. Statistical analysis was conducted using the Kolmogorov-Smirnov, Kruskal-Wallis, and Mann-Whitney tests (level of significance: P < 0.050). RESULTS: Imprint 4 Penta presented the highest overall accuracy, while Imprint 4 Preliminary Penta Super Quick displayed the poorest results. Regarding the model situation (impression scan vs cast scan), impression scans from Impregum Penta and Imprint 4 Penta showed superior results. CONCLUSION: Impression scans in combination with high-precision impression material results in the most accurate data.

RESUMEN

The current study aimed to evaluate the mechanical behavior of two different maxillary prosthetic rehabilitations according to the framework design using the Finite Element Analysis. An implant-supported full-arch fixed dental prosthesis was developed using a modeling software. Two conditions were modeled: a conventional casted framework and an experimental prosthesis with customized milled framework. The geometries of bone, prostheses, implants and abutments were modeled. The mechanical properties and friction coefficient for each isotropic and homogeneous material were simulated. A load of 100 N load was applied on the external surface of the prosthesis at 30° and the results were analyzed in terms of von Mises stress, microstrains and displacements. In the experimental design, a decrease of prosthesis displacement, bone strain and stresses in the metallic structures was observed, except for the abutment screw that showed a stress increase of 19.01%. The conventional design exhibited the highest stress values located on the prosthesis framework (29.65 MPa) between the anterior implants, in comparison with the experimental design (13.27 MPa in the same region). An alternative design of a stronger framework with lower stress concentration was reported. The current study represents an important step in the design and analysis of implant-supported full-arch fixed dental prosthesis with limited occlusal vertical dimension.

RESUMEN

BACKGROUND: Removal of cement-retained implant fixed restorations when needed, can be challenging. Conventional methods of crown removal are time consuming and costly for patients and practitioners. This research explored the use of two different types of pulsed erbium lasers as a non-invasive tool to retrieve cemented zirconia crowns from zirconia implant abutments. MATERIALS AND METHODS: Twenty identical zirconia crowns were cemented onto 20 identical zirconia prefabricated abutments using self-adhesive resin cement. The specimens were divided into two groups for laser assisted crown removal; G1 for erbium-doped yttrium aluminum garnet laser (Er:YAG), and G2 for erbium, chromium-doped yttrium, scandium, gallium and garnet (Er,Cr:YSGG). For the G1, after the first crown removal, the specimens were re-cemented and removed again using the Er:YAG laser. Times needed to remove the crowns were recorded and analyzed using ANOVA (α = 0.05). The surfaces of the crown and the abutment were further examined using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) analyses. RESULTS: The average times of zirconia crown removal from zirconia abutments were 5 min 20 sec and 5 min 15 sec for the Er:YAG laser of first and second experiments (G1), and 5 min 55 sec for the Er,Cr:YSGG laser experiment (G2). No statistical differences were observed among the groups. SEM and EDS examinations of the materials showed no visual surface damaging or material alteration from the two pulsed erbium lasers. CONCLUSIONS: Both types of pulsed erbium lasers can be viable alternatives for retrieving a zirconia crown from a zirconia implant abutment. Despite operating at different wavelengths, the Er:YAG and Er,Cr:YSGG lasers, perform similarly in removing a zirconia crown from a zirconia implant abutment with similar parameters. There are no visual and elemental composition damages as a result of irradiation with pulsed erbium lasers.

RESUMEN

El presente es un trabajo de investigación bibliográfica que busca establecer la posibilidad de utilizar las cefalometrías como elementos de diagnóstico pronóstico y elaboración de prótesis. Centra su objeto de estudio en encontrar y clasificar los factores morfológicos y funcionales que varían con los biotipos craneofaciales y que son de interés en la prostodoncia. La metodología empleada fue la revisión de la literatura histórica hasta la actualidad en la que se relacionan temas de prostodoncia a los biotipos craneofaciales. Si bien solo dos autores relacionaron la prostodoncia con los biotipos cráneo faciales, sí se encontraron varios temas de interés asociados directamente a la prostodoncia. Se clasificaron en temas de oclusión: Curva de Spee, plano de oclusión, movimientos mandibulares, dimensión vertical oclusiva y de especio libre interoclusal. Tema de maloclusiones. Tema de fuerza muscular. Tema variaciones morfológicas de procesos alveolares, corticales ósea y de la forma dentaría. Encontrándose para cada uno de ellos alguna correlación positiva con los distintos tipos faciales. De este estudio, se concluye que es necesario sistematizar el estudio de los conocimientos que puede aportar la cefalometría como una importante herramienta de diagnóstico al prostodoncista a partir de haberse encontrado variaciones muy importantes en los aspectos mencionados que hacen al interés de la rehabilitación prostodóncica (AU)


This Work is a bibliographic research that seeks to establish the use of cephalometries as elements of diagnosis prognostic and prosthesis elaboration. Its focus is to find and classify morphological and functional factors that vary with facial types which are of interest in prosthodontics. This was a review of the historical literature to date, in which prosthodontics are related to facial types. Although only two authors related prosthodontics to facial ypes, they did find several topics of interest directly associated with prosthodontics. They were classified into occlusion themes: Spee curve, occlusion plane, mandibular movements, occlusive vertical dimension and interocclusal free space. Malocclusion issue. Muscle strength theme. Morphological variations of alveolar processes, cortical bone and dental morphology. They found some positive correlation with the different facial types for each of them. From this study, it is concluded that it is necessary to systematize the study of cephalometries because they can provide to be an important diagnostic tool to the prosthodontist because there were found very important variations in the mentioned aspects that are of interest in prosthodontic rehabilitation (AU)

RESUMEN

INTRODUCTION: Identifying factors related to the quality of life constitutes strategy for the actions supporting and monitoring the population health. OBJECTIVE: To assess oral health practices in the elderly, the clinical conditions of oral health of the caregiver and the elderly and oral health-related quality of life of caregiver. METHODS: Oral health was evaluated in 388 participants (194 caregivers and 194 elderly) by: the decayed, missing and filled teeth (DMFT) index, the use and need of prosthesis, the Oral Health Impact Profile (OHIP-14) scale and a semi-structured questionnaire. RESULTS: Most caregivers (91.3%) acquired oral health knowledge in daily practice, 33% performed oral hygiene in the elderly and 28% reported difficulties with this activity. The average DMFT was 19.24 for caregivers and 28.70 for the elderly, both with predominance of missing teeth. Prostheses were used by 57.73% of caregivers and 63.40% of elderly. The need of protheses was high, mostly in the mandible, respectively 34.54% and 51.55%. The association between OHIP-14 and the need for total prosthesis showed an impact on the dimensions physical and psychological disabilities. The importance of religion affected the dimension psychological discomfort and physical and psychological disabilities. Caregivers over 60 years old had a 1.2 greater chance of oral health impact on quality of life compared to the 20 to 60-year-old group. CONCLUSION: The presence of low-value cultural contexts of self-care associated with a positive perception of oral health, even in precarious clinical conditions, minimized the impact on caregivers' quality of life.


INTRODUÇÃO: Identificar fatores relacionados à qualidade de vida constitui estratégia para as ações de suporte e acompanhamento da saúde da população. OBJETIVO: Avaliar as práticas em saúde bucal nos idosos, as condições clínicas de saúde bucal do cuidador e do idoso e a qualidade de vida relacionada à saúde bucal dos cuidadores. MÉTODOS: A saúde bucal foi avaliada em 388 participantes (194 cuidadores e 194 idosos) usando: índice dentes cariados, perdidos e obturados (CPOD), uso e necessidade de próteses, instrumento Oral Health Impact Profile (OHIP-14) e questionário semiestruturado. RESULTADOS: A maioria dos cuidadores (91,3%) adquiriu conhecimento em saúde bucal na prática diária, 33% realizava higiene bucal no idoso e 28% relatou ter dificuldades com esta atividade. Registrou-se CPOD 19,24 para cuidadores e 28,70 para idosos, ambos com predomínio do compo­nente perdido. Dos cuidadores, 57,73% usava prótese e dos idosos, 63,40%. A necessidade das próteses foi alta principalmente na mandíbula, respectivamente 34,54% e 51,55%. A associação entre OHIP-14 e a necessidade de prótese total evidenciou impacto nas dimensões incapacidades física e psicológica. A importância da religião associou-se a impactos nas dimensões desconforto psicológico e incapacidades física e psicológica. Os cuidadores com 60 anos ou mais apresentaram chance de 1,2 vezes maior de impacto da saúde bucal na qualidade de vida quando comparados ao grupo de 20 a 60 anos. CONCLUSÃO: O impacto na qualidade de vida dos cuidadores foi minimizado pela presença de contextos culturais pouco valorativos de autocuidado associados à percepção positiva de saúde bucal, mesmo em condições clínicas precária.

RESUMEN

As próteses removíveis são consideradas facilitadoras em potencial da estomatite protética, caracterizada por aspectos hiperplásicos e eritematosos na mucosa de suporte. Este trabalho tem como objetivo relatar as principais manifestações orais da estomatite protética em um paciente geriátrico associada a candidíase oral pseudomembranosa. Paciente do gênero masculino, setenta e quatro anos, apresentava uma lesão exofítica, na região de palato com dois centímetros de extensão, além da presença de candidíase pseudomembranosa, fazia o uso de uma prótese parcial superior removível há aproximadamente dez anos. Foi levantada a hipótese diagnóstica de estomatite protética associada a candidíase pseudomembranosa. A terapêutica instituída consistiu no uso de antifúngico por um período de quinze dias e biópsia incisional. O exame histopatológico confirmou o diagnóstico de hiperplasia fibrosa inflamatória. Foi recomendado a confecção de uma nova prótese para que fosse evitado a recorrência da lesão, e o paciente também foi instruído quanto a sua higiene oral evitando-se desta forma a recorrência da candidíase. O cirurgião-dentista deve ser capaz de reconhecer e diagnosticar a estomatite protética em sua prática diária e tratar o paciente de acordo com a sua etiologia, oferecendo desta forma para o paciente um maior conforto e melhores condições de vida(AU)


Removable total dentures are considered potential facilitators of prosthetic stomatitis, characterized by hyperplastic and erythematous aspects in the supporting mucosa. This paper aims to report the main oral manifestations of prosthetic stomatitis in an elderly patient associated with pseudomembranous oral candidiasis. A seventyseven-year-old male patient presented with an exophytic lesion in the palate region of two centimeters in length, in addition to the presence of pseudomembranous candidiasis, and had been using a removable upper partial denture for approximately ten years. The diagnostic hypothesis of prosthetic stomatitis associated with pseudomembranous candidiasis was raised. The therapy instituted consisted of the use of antifungal for a period of fifteen days and incisional biopsy. Histopathological examination confirmed the diagnosis of inflammatory fibrous hyperplasia. It was recommended to make a new prosthesis to avoid recurrence of the lesion, and the patient was also instructed as to its oral hygiene, thus avoiding the recurrence of candidiasis. The dentist should be able to recognize and diagnose prosthetic stomatitis in his daily practice and treat the patient according to its etiology, thus offering the patient greater comfort and better living conditions(AU)

RESUMEN

A busca por restaurações estéticas e duradouras com resultados mais semelhantes à dentição natural está cada vez mais evidente, a adequação dos materiais e das técnicas foram a saída para atender à exigência estética e mecânica dos pacientes. O objetivo desse trabalho é relatar um caso clínico no qual aborde uma reabilitação oral complexa por meio de próteses fixas metalocerâmicas. A paciente apresentava problemas estéticos e funcionais e ao exame clínico foi contatado próteses fixas metalocerâmicas desadaptadas e desgastes severos nas duas arcadas. O desgaste resultou em uma desarmonia no seu sorriso, além de uma discrepância no contorno gengival em incisivos laterais, caninos e pré-molares. No planejamento clínico realizou-se gengivoplastia para adequar contorno gengival e próteses fixas do tipo metalocerâmica dos elementos 14 ao 26. Concluímos que as restaurações com as coroas metalocerâmicas se mostraram uma excelente alternativa para reabilitações protéticas amplas, atendendo todas as expectativas estéticas e funcionais da paciente possibilitando uma melhora significativa em sua qualidade de vida(AU)


The search for aesthetic and lasting restorations with results more similar to natural dentition is increasingly evident, the adequacy of materials and techniques have been the output to meet the aesthetic and mechanical demands of patients. The aim of this paper is to report a clinical case in which a complex oral rehabilitation using fixed metalloceramic prostheses is addressed. The patient presented aesthetic and functional problems and the clinical examination was contacted maladaptive fixed metalloceramic prostheses and severe wear on both arches. The wear resulted in a disharmony in his smile, as well as a discrepancy in the gingival contour in lateral, canine and premolar incisors. In the clinical planning, gingivoplasty was performed to adapt the gingival contour and the metalloceramic fixed prostheses of elements 14 to 26. We conclude that the restorations with the metalloceramic crowns proved to be an excellent alternative for broad prosthetic rehabilitation, meeting all the aesthetic and functional expectations of the patient. enabling a significant improvement in their quality of life(AU)

RESUMEN

Abstract This cross-sectional study aimed to investigate the association between the Sense of Coherence and impact of oral health on the quality of life. Was conducted with a sample of 720 individuals of both sexes, between the ages of 50 and 74 years, selected through multistage proportional random sampling. The data collection instruments used were: short version of the Sense of Coherence Scale (SOC-13), Oral Impacts on Daily Performances (OIDP) questionnaire, oral clinical examination and questionnaire containing socio demographic and use of dental services information. Bivariate and multivariate analyses were performed through Poisson regression adjusted for robust variance, with level of significance p < 0.05. Oral impacts were reported by 416 participants (57.8%). In the adjusted model, those with strong SOC were more likely of not having any impact when compared with individuals with weak SOC (PR=1.30). Need for dental prosthesis was also associated with the outcome, individuals who did not require prosthesis had less impact (PR=1.50). The findings showed that SOC is associated with OIDP, supporting the hypothesis that individuals with strong SOC present a lower impact of oral health on the quality of life, suggesting that SOC is a determinant that can provide protection against that impact.


Resumo Este estudo transversal objetivou investigar a associação entre Senso de Coerência (SOC) e o impacto da saúde bucal na qualidade de vida. Foi realizado com uma amostra de 720 indivíduos de ambos os sexos, com idade entre 50 e 74 anos, selecionados por amostragem aleatória proporcional em múltiplos estágios. Os instrumentos de coleta de dados foram: versão curta da Sense of Coherence Scale, questionário Oral Impact on Daily Performance (OIDP), exame clínico bucal e questionário sociodemográfico e de uso de serviços odontológicos. As análises bivariadas e multivariadas foram realizadas por regressão de Poisson ajustada para variância robusta, com nível de significância p < 0,05. O impacto da saúde bucal foi relatado por 416 participantes (57,8%). No modelo ajustado, aqueles com SOC forte foram mais propensos a não ter nenhum impacto, comparados aos indivíduos com SOC fraco (PR=1,30). A necessidade de prótese dentária também foi associada ao desfecho e os indivíduos que não necessitavam prótese tiveram menor impacto (PR=1,50). Os resultados mostraram que o SOC está associado ao OIDP, apoiando a hipótese de que os indivíduos com SOC forte apresentam menor impacto da saúde bucal na qualidade de vida, sugerindo que o SOC é um determinante que pode proporcionar proteção contra esse impacto.

RESUMEN

This study aimed to investigate factors associated with dental prosthesis procedures by oral health teams (OHTs) in the Brazilian primary health care in 2013-2014, who participated in the National Program for Improving Access and Quality of Primary Health Care (PMAQ-AB). This is an analytical cross-sectional study using a questionnaire with dichotomous questions applied in 18,114 OHTs. The dependent variable studied was making any type of prosthesis (removable or fixed). Independent variables involved issues related to human resources and health service management. Data were submitted to simple and multiple binary logistic regression with odds ratio calculation, 95% confidence intervals, and p-values. Most OHTs (57%) do not perform any dental prosthesis. The teams that are more likely to perform dental prostheses have human resources-related characteristics, such as professionals admitted through public examinations (OR 1.25, 95% CI 1.14-1.36) and those involved in permanent education (OR 1.13, 95% CI 1.02-1.26). Moreover, OHTs with a more organized work process and that receive more significant support from municipal management are more likely to perform dental prostheses (p < 0.05). The oral health teams which tended to provide the most dental prostheses to benefit patients were; hired as civil servants, had a municipal career plan, involved all members of the oral health team, and trained undergraduate dental students from outreach programs. Better organizational support and improved work incentives may be needed to get the majority of oral health teams to start providing dental prostheses to their patients.

RESUMEN

RESUMEN Introducción: El edentulismo es la pérdida total o parcial de dientes, ocasionado principalmente por la caries y la enfermedad periodontal; es un proceso gradual que está comúnmente asociado al aumento de edad. Actualmente es considerado una discapacidad debido a la limitación funcional que ocasiona en quien lo presenta. Objetivo: Exponer el tratamiento rehabilitador multidisciplinario, funcional y estético en un paciente con desarmonías oclusales. Presentación del caso: Paciente masculino de 74 años, diagnosticado con edentulismo parcial bimaxilar, mediante examen clínico y radiológico. Se sometió a terapia periodontal generalizada, cirugía preprotésica, restauración de plano oclusal de forma directa e indirecta y rehabilitación bucal con prótesis removibles total superior y parcial inferior; lo cual le permitió recuperar funcionalidad, estética y autoestima. Conclusiones: El edentulismo desencadena alteración en el estado funcional y emocional del paciente. Un diagnóstico integral y plan de tratamiento multidisciplinario y ordenado desencadenó éxito en el presente caso(AU)


ABSTRACT Introduction: Edentulism is total or partial tooth loss mainly caused by dental caries and periodontal disease. It is a gradual process often associated to aging. At present edentulism is considered to be a disability, due to the functional limitations undergone by sufferers. Objective: Describe the multidisciplinary, functional and esthetic rehabilitation treatment provided to a patient with occlusal disharmony. Case presentation: A 74-year-old male patient was diagnosed with bimaxillary partial edentulism based on clinical and radiographic examination. The patient underwent generalized periodontal therapy, pre-prosthetic surgery, direct and indirect occlusal plane restoration, and oral rehabilitation with total upper and partial lower removable prostheses, as a result of which he recovered his functionality, esthetic appearance and self-esteem. Conclusions: Edentulism triggers changes in the functional and emotional state of patients. Comprehensive diagnosis and orderly multidisciplinary treatment led to success in the case herein presented(AU)

RESUMEN

OBJECTIVES: The aim of this study was to assess diagnosis and treatment of submandibular duct stenosis caused by dental prostheses. STUDY DESIGN: This retrospective study included 9 patients with papillary stenosis caused by physical irritation of the Wharton duct ostium by a mandibular dental prosthesis. Diagnostics included physical examination, as well as transcutaneous and transoral ultrasound examinations. Treatment consisted of duct incision, papillotomy, and subsequent sialendoscopy. After surgery, patients were advised to have the dental prosthesis altered by the dentist and to have regular gland massage. Follow-up data were obtained via telephone interviews. The most important outcome parameter was a symptom-free state. RESULTS: In all 9 patients, the insertion of the sialendoscope was initially impossible because of the stenosis. After duct incision, sialendoscopy ruled out other obstructive causes and inflammatory states, leaving the dental prosthesis as the only underlying cause of the obstruction. Seven of the 9 treated patients were interviewed after a follow-up period of 28.1 (± 25.4) months. The procedures had resulted in all patients being symptom-free, without any reported complications. CONCLUSIONS: Mandibular prostheses can cause stenosis of the papillary region with subsequent submandibular duct obstruction. Surgical therapy is easy to perform and results in excellent long-term outcomes.

RESUMEN

In order to provide restorations and dental prostheses that are esthetically pleasing, functional and in harmony with a patient's occlusion, practitioners must have a thorough knowledge of dental anatomy. Recent studies have shown that virtual three-dimensional (3D) models greatly enhance educational outcomes in dental anatomy courses. This article describes a novel educational technique and uses videos and web-based portals to demonstrate how to create a virtual 3D tooth model from a scan of a natural tooth for use in dental anatomy courses.
