Flexural Strength of Interim Resin Materials for Fixed Prosthodontics

Abstract

Bis-acryl interim materials exhibited higher flexural strength than the methacrylate resins tested in this study. These higher values should be considered in making interim fixed prostheses, especially when long-term use or long-span FPDs are planned.

Finite Element Analysis of Provisional Structures of Implant-Supported Complete Prostheses

“…Because repair resins are materials with different values of flexural strength, a direct comparison of the results between Tempron and Luxatemp resins should not be made. However, in accordance with the literature, the mean values found for flexural strength of the materials under 3-point flexural tests were 64.31 MPa (SD 7.29 MPa) 17 for Tempron resin and 114.6 MPa (SD 26.6 MPa) 18 for Luxatemp resin, which was used as a reference according to the standardized tests of the American Dental Association. Next, a ratio percentage in relation to the results was applied to be equivalent.…”

Reforço da resina acrílica para restaurações provisórias utilizando diferentes formatos e posições do fio ortodôntico

“…Testes in vitro de carregamento estático difere das condições dinâmicas intraorais reais (18,19). O carregamento cíclico pode ser incorporado para simular o ambiente clínico, uma vez que, microtrincas e defeitos se propagam em materiais assim como a resina acrílica durante processos térmicos ou mecânicos, o que pode reduzir significantemente sua resistên-cia (20).No presente estudo, nenhum carregamento cíclico em ambiente úmido foi realizado, sendo uma limitação do estudo.…”

An in- vitro study to compare and evaluate the hardness of various commercially available provisional restorative materials

“…The importance is to withstand the environment of the oral cavity. 3 Various materials used as provisional restorations include methyl methacrylates, ethyl methacrylates, bis-acryl resin composites etc. such restorations also act as an effective diagnostic tool to check any alteration in occlusion or an evoked pulpal response.…”

“…This polymer withstands the occlusal forces and the oral environment till a definitive restoration is provided. 3 So, the provisional restoration can be divided into either a fixed or removable prosthesis which are made to provide proper esthetics and functional stability for a sometime and then it is to be replaced with a final definitive prosthesis. 6 All the clinicians should be familiar with all the interim materials along with their mechanical properties that are available commercially in order to make the right choice of material according to the case conditions.…”
