ABSTRACT

 Compression molding with heat activation for resin polymerization is the conventional method for processing acrylic resin in removable and maxillofacial prosthesis. Overtime, different processing methods have been improved to overcome physical and chemical problems in cured resin with conventional technique. Enough knowledge about each method is necessary for both dentist and laboratory technician. The aim of this study is review the improved techniques for curing resin and comparison between them. An online search of PubMed, Scopus, Science Direct, and Google Scholar was conducted using key words “denture possessing technique” and “acrylic resins” from 1970 until September 2018. The most common and successful techniques are injection molding and conventional methods. CAD/CAM technologyis especially useful for maxillofacial prosthesis but still needs more studies. Keywords: Denture possessing technique, Acrylic resins, Maxillofacial prosthesis, Removable prosthesis.
