dc.description.abstract | Statement of problem: Complete-arch implant-supported prostheses without a framework have a high risk of failure: a straightforward and inexpensive reinforcement material, such as nylon mesh, could improve their longevity. Purpose: The purpose of this in vitro study was to evaluate a nylon-silica mesh compound on the fracture strength of acrylic resin and the fracture load of complete-arch implant-supported prostheses. Material and methods: Twenty-four complete mandibular arch implant-supported prostheses were divided into 2 groups according to cantilever length (molar and premolar) and subdivided into another 2 subgroups according to the presence or absence of reinforcing mesh. The specimens were submitted to a maximum load-to-fracture test in a universal testing machine, with a 100-N load cell, a 2 mm/min crosshead speed, and a spherical metal tip diameter of 4 mm at different points (molar and premolar). These were submitted to 1-way analysis of variance for repeated measurement and the post hoc Tukey multiple comparison test (α=.05). Results: The mean maximum load ±standard deviation for the molar group was 393.4 ±95.0 N with reinforcement and 305.4 ±76.3 N without reinforcement (P=.02); and for the premolar group was 1083.3 ±283.7 N with reinforcement and 605.3 ±90.5 N without reinforcement (P=.001). Conclusions: Reinforcement with nylon mesh increased the mean maximum load of implant-supported complete-arch prostheses at both cantilever lengths. The cantilever to the premolar (5 mm) presented the highest maximum load values to fracture. © 2017 Editorial Council for the Journal of Prosthetic Dentistry | en |
dc.description.abstract | Declaração do problema: As próteses com implantes de arco completo, sem estrutura, apresentam alto risco de falha: um material de reforço direto e barato, como a malha de nylon, pode melhorar sua longevidade. Objetivo: O objetivo deste estudo in vitro foi avaliar um composto de tela de nylon-sílica sobre a resistência à fratura da resina acrílica e a carga de fratura das próteses suportadas por implantes de arco completo. Material e métodos: Vinte e quatro próteses completas apoiadas em implantes do arco mandibular foram divididas em 2 grupos de acordo com o comprimento do cantilever (molar e pré-molar) e subdivididas em outros 2 subgrupos de acordo com a presença ou ausência de tela de reforço. Os espécimes foram submetidos a um teste de carga máxima à fratura em uma máquina universal de teste, com célula de carga 100-N, velocidade de 2 mm / min na cruzeta e diâmetro esférico da ponta do metal de 4 mm em diferentes pontos (molar e pré-molar). Estes foram submetidos à análise de variância unidirecional para medição repetida e ao teste de comparação múltipla post hoc de Tukey (α = 0,05). Resultados: A carga máxima média ± desvio padrão para o grupo molar foi de 393,4 ± 95,0 N com reforço e 305,4 ± 76,3 N sem reforço (P = 0,02); e para o grupo pré-molar foram 1083,3 ± 283,7 N com reforço e 605,3 ± 90,5 N sem reforço (P = 0,001). Conclusões: O reforço com tela de nylon aumentou a carga máxima média de próteses de arco completo suportadas por implante em ambos os comprimentos em consola. O cantilever para o pré-molar (5 mm) apresentou os maiores valores de carga máxima para fraturar. | pt_BR |
