Magister Chirurgiae Dentium - MChD / A well designed metal-based removable partial denture (MBRPD) is a cost-effective and a conservative method of rehabilitating a partially edentulous mouth. The MBRPD demands that the abbutment tooth provides support and/or retention while the abutment tooth, in turn, expects the MBRPD to transmit the forces axially and to be passive when fully seated. For vertical forces to be transmitted axially, occlusal rest seats have to be prepared on the abutment teeth to receive a cast metal rest of the MBRPD. The  objective of this study was to compare occlusal rest seat preparations for metal-based removable partial dentures (MBPRD) prepared by dental students at the UWC Oral Health centres, to the corresponding cast metal rests and to determine action taken in response to discovered discrepancies between the rest seat preparation depth and the cast metal occlusal rset thickness. / South Africa

Entretanto, poucos são aqueles que avaliam a mastigação de pacientes parcialmente edêntulos, comparando a função mastigatória após a reabilitação por meio de diferentes próteses parciais, o qual foi o objetivo deste ensaio clínico pareado. Para tanto, foram selecionados 12 voluntários (8 gênero feminino, idade média 62.6 ± 7.8 anos), apresentando edentulismo total superior e parcial inferior (classe I de Kennedy), os quais receberam, de forma sequencial, próteses parciais removíveis (PPR), PPR com encaixe implanto-retido (PPRI) e prótese parcial fixa sobre implantes (PPFI). Todos os tratamentos foram realizados na mandíbula e utilizados por 2 meses antes da avaliação mastigatória, enquanto a maxila recebeu uma nova prótese total que foi utilizada durante todo o estudo. A mastigação foi avaliada por meio da mensuração da performance mastigatória (PM), índice de trituração dos alimentos (ITA), força máxima de mordida (FMM), espessura dos músculos masseter e temporal, movimento mastigatório, limiar de deglutição (LD), habilidade mastigatória, estado nutricional, qualidade de vida (QV) e satisfação do paciente. Foi realizada a análise exploratória dos dados e aplicada análise de variância para medidas repetidas seguido de teste de Tukey-Kramer para as comparações múltiplas entre os tratamentos. Todas as análises foram realizadas utilizando SAS software (release 9.1, 2003; SAS Institute Inc., Cary, USA) (p ? 0.05). A PM melhorou consideravelmente após o uso de PPRI e PPFI com aumento de 85% e 87%, respectivamente. Resultados similares foram observados em relação ao ITA e à FMM com aumento (p ? 0.0001) de 91% e 62% no ITA de 79% e 62% na FMM após o uso de PPRI e PPFI, respectivamente. Independente do tipo de prótese, o uso de PPRI e PPFI aumentou a espessura do masseter durante a contração voluntária máxima (p ? 0.0001) e alterou o movimento mastigatório, reduzindo o tempo total do ciclo, bem como a duração das fases de abertura e fechamento (p ? 0.05). A habilidade mastigatória melhorou após o uso da PPRI e PPFI, independente do alimento avaliado. O LD foi alterado pelo tratamento reabilitador, com redução no número de ciclos e tamanho da partícula triturada, sendo os menores valores observados com o uso da PPFI. Houve aumento no consumo de fibras (p = 0.007), cálcio (p = 0.001) e ferro (p = 0.02) após o uso de PPFI, além da redução no consumo de alimentos com altos níveis de colesterol (p = 0.02). A satisfação aumentou (p ? 0.05) e o impacto da saúde oral na QV reduziu, tanto no score geral (p = 0.04) quanto no domínio de dor física (p = 0.02) após o uso da PPFI. A reabilitação de pacientes parcialmente edêntulos com PPRI e PPFI melhorou significativamente a função mastigatória e a magnitude do efeito relacionou-se ao tipo de prótese / Abstract: Studies revealed the masticatory improvement after the use of prosthesis over dental implants. However, few are those who evaluated the chewing of partially edentulous patients, comparing the masticatory function after treatment with different partial dentures, which was the aim of this paired clinical trial. Therefore, 12 volunteers (8 females, mean age 62.6 ± 7.8 years) presenting total edentulism in maxilla and partial edentulism in the mandible (Kennedy class I) were selected and received, in a sequential way, a conventional removable partial dentures (RPD), implant-retained partial dentures (IRPD) and implant fixed partial denture (IFPD). All treatment were assembled in the mandible and used for 2 months, while the edentulous maxilla received a new complete denture which was used throughout the study. Mastication was assessed by measuring masticatory performance (MP), food comminution index (FCI), maximum bite force (MBF), masseter and temporal muscle thickness, chewing movements, swallowing threshold (ST), masticatory ability, nutritional status, quality of life (QOL) and patient satisfaction. Data were analyzed and repeated measures analysis of variance was applied followed by Tukey-Kramer multiple for comparisons between treatments. All analyzes were performed using SAS software (release 9.1, 2003, SAS Institute Inc., Cary, USA) (p ? 0.05). MP greatly improved after IRPD and IFPD use with an increase of 85% and 87% respectively. Similar results were observed in respect to FCI and MBF with an increase (p ? 0.0001) of 91% and 62% in FCI and of 79% and 62% in MBF after the IRPD and IFPD use, respectively. Regardless the prosthesis type, the use of IRPD and IFPD increased the masseter thickness during maximum voluntary clenching (p ? 0.0001) and altered the chewing movements, reducing the total cycle time, as well as the duration of opening and closing phases (p ? 0.05). MA improved after IRPD and IFPD use, irrespectively of the food rated. ST was affected by prosthetic treatment, showing a reduction in the number of chewing cycles and in the size of the comminuted particle, with the lowest values observed after IFPD use. There was a raise in fiber (p = 0.007), calcium (p = 0.001) and iron (p = 0.02) intake after the IFPD use and a reduction in the intake of food with high cholesterol levels (p = 0.02). Patients satisfaction also increased (p ? 0.05) and the impact of oral health on QOL decreased in overall score (p = 0.04) and in the physical pain domain (p = 0.02) after the IFPD use. The rehabilitation of partially edentulous patients with IRPD and IFPD significantly improved masticatory function and the magnitude of the effect was related to the prosthesis type / Doutorado / Protese Dental / Doutora em Clínica Odontológica
