An injection molding device, improving the existing injection system for acrylic denture fabrication

Abstract

INTRODUCTION: The advantages of injection molding system (IMS) are precise adaptation of acrylic to master cast, continuous compensation of acrylic shrinkage, low porosity and better physical properties of dentures. Traumatic, toxic and allergic complications are reduced. The existing IMS produces only one denture at a time. Using standard capsules leads to waste of material. Removable partial acrylic dentures (RPAD) with wire clasps haven't been fabricated yet.
