ABSTRACT

Nowadays, a lot of people need in reconstruction of the teeth in connection with their loss. Before prosthetics or any other manipulations, a person wants to quickly see the aesthetic appearance of his future tooth. At the moment, many dentists use the option of verbal explanation to the patient, what will look like a smile or a front row of teeth after treatment, but the visual representation of the person remains aside. But now this can be achieved with the help of "Digital smile design", which shows the person the final result of the dentition. This technology has a number of advantages. Some of them are the rapid creation of a prototype model and high accuracy in the manufacture of work. Thanks to these technologies, communication between the specialist and the patient has been facilitated. The digital smile design has simplified the doctor's work process and reduced patient data processing time. From now on, achieving aesthetic results in the reconstruction of teeth for the dentist is not a problem.

ABSTRACT

This study aims to apply a new expert system to design removable partial denture (RPD) framework. The RPD design is completed in three steps, namely, "selecting missing teeth", "selecting abutment condition", and "selecting personalized clasp". The system can help auxiliary dentists develop personalized treatment plans to reduce their clinical workload. It can also generate a dental preparation guideline for clinical preparation, which can prevent tooth preparation mistakes. By generating the standard electronic drawings of the framework design, the system can reduce the inconvenience caused by manual drawing, thereby facilitating dentist-technician communication and reducing the rate of remade.

ABSTRACT

OBJECTIVE@#This study aims to investigate the fracture resistance and short-term restorative effects of resin-bonded fixed partial dentures (RBFPDs) made from heat-pressed lithium-disilicate-based glass-ceramic (IPS e.max press) and zirconia ceramic (WIELAND) and retained by all-ceramic guiding plates when used to restore missing mandibular second premolars.@*METHODS@#A total of 64 human mandibular first premolars and first molars were prepared as abutments, then were randomly divided into 4 groups (n=8): E0, heat-pressed ceramic RBFPDs, no cyclic loading; E1, heat-pressed ceramic RBFPDs exposed to 300 000 cycles of dynamic loading; W0, zirconia ceramic RBFPDs, no cyclic loading; and W1, zirconia ceramic RBFPDs exposed to 300 000 cycles of dynamic loading. Fracture strength was tested in a universal testing machine.@*RESULTS@#The medians of fracture strength were 1 242.85 N±260.11 N (E0), 1 650.85 N±206.77 N (W0), 1 062.60 N±179.98 N (E1), and 1 167.61 N±265.50 N (W1). Statistical analysis showed that all the groups exhibited significantly higher fracture strength compared with the maximum bite force in the premolar region (360 N; P0.05). Significant statistical differences were found between the zirconia ceramic groups (W0 and W1, P0.05) after dynamic loading.@*CONCLUSIONS@#The RBFPDs retained by all-ceramic guiding plates exhibited promising fracture properties and optimal short-term restorative effects when used to restore missing mandibular second premolars.

ABSTRACT

Abstract The aim of this is was evaluate the vertical and horizontal marginal adaptation of 3-unit fixed partial denture frameworks fabricated using different techniques and CAD/CAM systems. A total of 40 framework specimens were fabricated and divided into four groups as follows: lost-wax casting (G1); lost-wax casting with welding (G2); extraoral optical scanning of models (3S/DWOS) (G3); intraoral optical scanning (Cerec Bluecam/Sirona) (G4). A reference model was used to simulate a fixed partial denture with three elements (with a central pontic). The frameworks of G1 and G2 were cast in nickel-chromium (NiCr) alloy, whereas those of G3 and G4 were milled in zirconia. In all groups, vertical and horizontal marginal adaptation (over-contour and under-contour) was evaluated using a three-dimensional optical microscope (Quick Scope, Mitutoyo). The results showed higher vertical marginal misfit in G1 than in the other groups (p<0.001). Regarding horizontal marginal misfit, higher over-contour values occurred in G3 than in the other groups (p<0.001). G3 did not show under-contour at all, whereas the other groups did not differ from each other in this regard (p>0.05). Within the limitations of this study, it can be concluded that lost-wax casting with welding is a viable alternative to the use of CAD/CAM systems to fabricate frameworks of three-unit FPDs, since the techniques yielded similar vertical misfit values. Extra-oral CAD/CAM systems showed the highest horizontal misfit (over-contour) compared to other groups.


Resumo O objetivo deste estudo foi avaliar a adaptação marginal vertical e horizontal de infraestruturas de prótese fixas de três elementos confeccionadas por diferentes técnicas e diferentes sistemas CAD/CAM. Um total de 40 infraestruturas foram confeccionadas e divididas em quatro grupos: fundição por cera perdida (G1); fundição por cera perdida com ponto de solda (G2); escaneamento óptico extraoral para escaneamento do modelo (3S/DWOS); escaneamento óptico intraoral (Cerec Bluecam/Sirona) (G4). Uma matriz metálica foi utilizada para simular uma prótese fixa de três elementos (com pôntico central). As infraestruturas do G1 e G2 foram fundidas em liga metálica de níquel-cromo (NiCr), enquanto que as infraestruturas de G3 e G4 foram fresadas em zircônia. Todos os grupos foram analisados quanto à adaptação marginal vertical e horizontal (sobrecontorno e subcontorno) em microscópio óptico tridimensional (Quick Scope, Mitutoyo). Os resultados apresentaram maiores valores de desadaptação marginal vertical no G1 comparados aos outros grupos (p<0,001). Em relação a desadaptação marginal horizontal, maiores valores de sobrecontorno foram observado no G3 em comparação com os demais grupos (p<0,001). Não foi observado valores de subcontorno para o G3, enquanto que os demais grupos não apresentaram diferença significante para o subcontorno (p> 0,05). Dentro das limitações do presente estudo, pode-se concluir que a técnica convencional após ponto de solda é uma alternativa viável para confecção de infraestruturas de próteses fixas de três elementos comparado ao uso de sistemas CAD/CAM, uma vez que as técnicas apresentaram valores de adaptação marginal vertical similares. Os sistemas CAD/CAM extraoral apresentou o maior desajuste horizontal (sobrecontorno) em comparação com outros grupos.

ABSTRACT

ABSTRACT Tooth and bone preservation is essential to support dentures, especially for elderly patients. Retaining the existing teeth and roots for an overdenture postpones edentulism, and this is a convenient alternative to complete dentures and extraction of teeth. Root-supported overdentures attach to the roots with precision attachments. The fit of the attachment of both the denture and the roots or implants is very important for overdentures. The combination of the attachments increases the retention and stability of attachment-retained overdentures. This technique describes an alternative procedure to fabricate root-supported overdentures with combined locator and casted telescopic attachments.


RESUMEN La preservación de los dientes y los huesos es esencial para apoyar las dentaduras postizas, especialmente para pacientes de edad avanzada. Retener los dientes y raíces existentes para una sobredentadura aplaza el edentulismo, y constituye una alternativa conveniente para completar las dentaduras postizas y la extracción de dientes. Las sobredentaduras apoyadas en la raíz se unen a las raíces con aditamentos de precisión. El ajuste del aditamento tanto de la dentadura como de las raíces o implantes es muy importante para las sobredentaduras. La combinación de los aditamentos aumenta la retención y la estabilidad de las sobredentaduras retenidas por aditamento. Esta técnica describe un procedimiento alternativo para fabricar sobredentaduras ancladas en la raíz con un localizador combinado y aditamentos telescópicos fundidos.

ABSTRACT

Occlusal disharmony is frequently observed among edentulous patients. When artificial teeth come into contact, the unfavorable displacing force may lead to the discomfort, mucosal trauma, or even neuromuscular alterations and emotional disturbances. An optimal occlusal scheme is a critical factor for successful complete dentures. For this case, an edentulous patient with significant interarch size discrepancy due to mandibular prognathism contributing to inadequate function of dentures was treated with complete dentures. The posterior cross-bite tooth setup for compensating the abnormal jaw relations provided a stable and retentive complete denture prosthesis, which was considered adequate by both patient and dentist.

ABSTRACT

Este artigo descreve os passos para a utilização da filosofia da Técnica da Zona Neutra. Através dessa filosofia, procura-se localizar uma área, em boca, onde as forças geradas pela língua são neutralizadas pelas forças geradas pelos lábios e bochechas, estabilizando assim a prótese.


This article describes step-by-step the application of the Neutral Zone technique philosophy. It is based upon the concept that for each individual patient, there is within the denture space a specific area where the function of the musculature will not unseat the denture and where forces generated by the tongue are neutralized by the forces generated by the lips and cheeks.

ABSTRACT

O anseio por um sorriso estético vem sendo cada vez mais o motivo pelo qual os pacientes procuram o tratamento odontológico. Para que os objetivos estéticos sejam alcançados, existem alguns princípios que auxiliam os profissionais da área a restabelecer a harmonia estética do sorriso de seus pacientes. As discrepâncias de tamanho dentário nos dentes anterossuperiores afetam a estética do sorriso, podendo causar a falta de uma relação de proporcionalidade entre eles, evidenciada pela presença de diastemas múltiplos no segmento estético anterior do arco. O diagnóstico da alteração de dimensão mésio-distal dentária deve ser realizado antes do tratamento ortodôntico pelo emprego da Análise de Bolton para a previsibilidade do tratamento. Para a correção dessas alterações, torna-se necessária uma interdisciplinaridade entre a Ortodontia e a Dentística Restauradora, em que, para a finalização satisfatória do tratamento ortodôntico. Foi utilizado a proporção áurea, aplicada às Grades de Levin, restabelecendo a estética do sorriso.


Most patients who search for dental care are interested on aesthetic improvement of their smile. In order to achieve a harmonic smile, there are some principles that guide dental professionals to restore dental aesthetics. The discrepancies related to the size and position of the anterior-superior teeth affect the esthetic of the smile. As there is no proportional relation between the teeth, it could determine the presence of multiple diastemas in this segment. Regarding the treatment plan, the analysis of dimensional changes in mesio-distal tooth size should be performed before orthodontic treatment, using the Bolton analysis for treatment predictability. After the analysis, if there is any discrepancy between the positioning of teeth and presence of diastema, a multidisciplinary intervention is necessary. It is possible to achieve esthetic results through a multidisciplinary approach with Orthodontics and Restorative Dentistry. For a satisfactory result of the treatment, the Levin scale, which is based on the Golden Proportion, was used to restore aesthetics.

ABSTRACT

O edentulismo é um problema de saúde pública que afeta indivíduos em diversas esferas de vida: fisiológica, psicológica e social. Para solucionar esse problema, a Odontologia dispõe de várias alternativas como próteses totais convencionais mucossuportadas e as próteses sobre implantes. A prótese implanto-suportada como alternativa para o tratamento do edentulismo apresenta resultados superiores quando comparada às próteses convencionais, pois tem a grande vantagem de proporcionar retenção através da fixação ao implante osseointegrado. A proposta de reabilitação com suporte de implantes tem revolucionado a Odontologia por proporcionar melhor conforto, eficiência na mastigação, estética superior, confiança ao falar em público e, portanto, melhora na qualidade de vida. Atualmente, há dois modelos de próteses aplicadas aos desdentados totais: sobredentaduras, que são as próteses totais móveis suportadas por implantes osseointegrados (overdenture Implanto-retidas) e próteses totais fixas designadas como protocolos fixos e/ou protocolo Brånemark. O presente trabalho tem como objetivo relatar um caso clínico de um paciente do sexo feminino reabilitado com prótese total convencional no arco superior e prótese total fixa implanto-suportada imediata e, posteriormente, mediata no arco inferior...


Edentulism is a public health problem that affects people in various spheres of life: physiological, psychological and social. To solve this problem, dentistry offers several alternatives such as conventional dentures and implant-supported prosthesis. The implant-supported prosthesis as an alternative for the treatment of tooth loss has higher results than conventional prostheses, due to the fact of providing retention through attachment to the osseointegrated implant. The proposal of rehabilitation through implant-supported prosthesis has revolutionized dentistry as it provides better comfort, efficiency in chewing, superior aesthetics, and security at public speaking, therefore, improving the quality of life. Currently, there are two models of prostheses applied to edentulous patients; overdentures that are mobile dentures supported by dental implants (Implant-retained overdenture) and fixed dentures designated as fixed protocols and /or Brånemark protocol. The aim of this study is to report a case of a female patient rehabilitated with conventional denture in the maxilla and implant-supported fixed denture immediate and subsequently mediate in the mandible...

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical performance of glass fiber reinforced resin-bonded fixed partial denture(GFR-RBFPD) as a periodontal splint on abutment teeth with reduced periodontal support.</p><p><b>METHODS</b>Thirty fixed-fixed GFR-RBFPD were delivered to restore anterior partial edentulous dentitions. The adjacent abutment teeth had severely reduced periodontal support and were not indicated for full crown retained FPD. The success rate and functional survival rate had been recorded and the periodontal condition had been evaluated for 4 years. The results were statistically analyzed with single factor variance analysis and chi square test(α=0.05).</p><p><b>RESULTS</b>In the first, second, and third year following restoration, one connector fractured in each year and they were repaired with adhesive resin and the pontics were kept in place for function. In the third and fourth years after restoration, there was one pontic displacement with fracture of connectors. The total survive rate was 83%(25/30) and the functional survival rate was 93% (28/30) at the end of the fourth year. The main reason of failure was fracture of connector. About 22%(13/60) of the adjacent teeth showed marginal bone height decrease, while the other 78% (47/60) increased with statistic significant difference from one year after the restoration to the end of the observation term(P<0.05). The periodontal condition of the adjacent teeth was improved after the restoration.</p><p><b>CONCLUSIONS</b>The four years clinical evaluation indicates that the GFR-RBFPD may be used as fixed prostheses to replace lost one to three anterior teeth with reduced periodontal support of abutment teeth.</p>
