A postsurgical upper complete denture was constructed with metal press-plate specially improved for applying the acrylic resin containing 4-META in the hemimaxillary edentulous patient. The whole process of denture construction is described and the resultant denture effect is evaluated by our test method in this paper. The main findings are: 1. The internal surface is quite smooth and clean 2. ...
Introduction: Acrylic resins (i.e., heat cured acrylic resins) are the most common materials used to manufacture removable dental prostheses involving maxillofacial such as obturators. Their mechanical and physical properties must be adequate for their use durability. It is therefore vital assess how affected by different disinfectants. Aims: The purpose of this research was evaluate effect che...
Background: Although most of the physical and mechanical properties of denture base resin polymerized by the conventional heat polymerization have been studied, the effect of autoclave processing in these properties has not been fully determined. The aim of the present study is to investigate the effect of two different cycles of autoclave processing on the transverse strength, impact strength,...
Introduction: The purpose of this study was to compare dimensional changes of two types of auto polymerizing acrylic resin patterns (APARPs) in three different storing environments. Methods: 60 acrylic post and core patterns were made of two types of Duralay acrylic resins (Aria dent, Iran and Reliance, Dental Mfg. Co, USA) using a canine model. Then coronal, apical diameter and coronoapical le...
