A proposta neste estudo foi verificar por meio da análise de tensão fotoelástica a influência exercida pela altura e largura da coroa protética na força transmitida aos implantes curto (7 mm) e longo (13 mm) quando o carregamento foi efetuado no centro ou na extremidade das coroas. As dimensões da altura e da largura da coroa simulada foram estabelecidas com base nas dimensões de dentes pré-molar e molar inferiores humanos e a espessura estabelecida em 6 mm. O corpo-de-prova de resina fotoelástica foi feito com o sistema bi componente à base de resina epóxi modificada e endurecedor. Os carregamentos foram de 0,4 kgf no centro e de 0,3 kgf numa das extremidade da coroa. A análise fotoelástica avaliando as ordens de franjas ao redor dos implantes foi feita com polariscópio de transmissão. Cada fotografia foi analisada três vezes no programa Fringes para ordens de franja de 0 a 4, considerando as médias da ordem das franjas e da tensão cisalhante para cada ponto estabelecido no modelo. Os dados foram submetidos à ANOVA dois fatores e diferenças estatísticas comparadas pelo teste t de Student em nível de significância de 5%. Os resultados mostraram que não houve diferença entre os níveis de tensões gerados pela altura e largura das coroas protéticas sobre os implantes curto e longo, quando os carregamentos foram feitos tanto no centro como na extremidade das coroas. Concluiu-se que as tensões geradas sobre os implantes curto e longo foram similares qualquer que fosse o tamanho e o local dos carregamentos aplicados sobre as coroas; houve diferença na magnitude da tensão exercida sobre os implantes curto e longo, sendo maior para o implante curto / Abstract: Short implants are used in clinical situations when the mass of bone is deficient in height and/or thickness. The purpose of this study was to verify the height and width crown influence in the stress transmission in short (7mm) and long (13mm) implants when loaded at center and edge of the crown. The simulated crown dimensions were established using a natural premolar and molar crown dimensions and the thickness was 6 mm. The photoelastic models were made using a dual system based on modified epoxi resin and catalyser. The crowns were loaded with 0,4 kgf at the center and 0,3 kgf at the edge. The photoelastic analysis for fringe order around the implants was made using a transmission polariscope. The maximum shear stress and the fringe values from 0 to 4 were determined in each photography measured three times using Fringes software. Two-way ANOVA and t Student test at 5% significance were perfomed. The results showed no difference in the stress levels produced by different height and width crown over the short and long implants when loaded both center and edge of the crowns. In conclusion, the results showed similar stress on the short and long implants regardless the size and the loaded crown area; however, there was statistical difference in the stress level on the implants being higher for the short implant / Doutorado / Protese Dental / Doutor em Clínica Odontológica
