Abstract

This study investigated the fracture load and deflection of acrylic resin specimens with different types of metal inserts. A metal adhesive denture resin (Meta Dent) and a conventional denture resin (Meliodent) were used with round metal, braided wires and mesh as inserts. There were eight groups and each group contained ten specimens. Each specimen was broken on a Monsanto testing machine using a three point load after storage in water at 37 degrees C for 48 hours. The results indicated that metal inserts enhanced the fracture resistance of both denture resins. No significant differences were found between the metal adhesive and conventional denture resin.

摘要

本研究调查了带有不同类型金属嵌体的丙烯酸树脂标本的断裂载荷和挠度。使用一种金属粘结义齿树脂（Meta Dent）和一种传统义齿树脂（Meliodent），并分别使用圆形金属、编织线和网作为嵌体。共有八组，每组包含十个标本。每个标本在37摄氏度的水中储存48小时后，在孟山都试验机上使用三点载荷进行折断测试。结果表明，金属嵌体增强了两种义齿树脂的抗断裂性。在金属粘结义齿树脂和传统义齿树脂之间未发现显著差异。
