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. https://jcr.tums.ac.ir/index.php/jcr/article/view/258 https://jcr.tums.ac.ir/index.php/jcr/article/download/258/240
