A Narrative Review of Different Types and Processing Methods of Acrylic Denture Base Material

Abstract

Acrylic resin is commonly used to fabricate removable prostheses due to its adequate physical, mechanical properties and cost effectiveness. There has been continuous development of the materials to improve their properties and to widen its application in different clinical setting. To study the history development of the acrylic resin and elaborate on the properties of different types and the processing methods of acrylic resins used to fabricate denture base which are commercially available in the market. This would help the dental clinician in choosing the best material of choice. The authors have summarized the history, development and classification of different types of acrylic resins used in fabricating denture and processing methods based on all the published research available on this topic using published materials available in the Dental Library, University of Malaya and the database (Science Direct, PubMed). Every type of acrylic denture base material has its pros and cons. Therefore, careful selection of material and the processing method is crucial to ensure the best outcome for prosthodontic treatment. Hence, upholding the patients' best interest and improving their quality of life. www.adum.edu.my

Protocols of improvements for PMMA denture base resin: An overview

“…An adequate method for acrylic polymerization maximizes the attributes of the polymer, such as lower porosity, monomer release, and flexural strength [68]. Despite the benefits offered by the conventional method, such as simplicity, ease, and cost-effectiveness, the main drawback has been the prolonged curing period desired [26]. The pressure plays a crucial function in accelerating the initial polymerization as well as decreasing the pores and remaining monomer level, thereby improving the flexural strength.…”

“…Several attempts have been made to examine the impact of these two systems on the physical and mechanical characteristics of PMMA; however, controversial outcomes have been found, and both processing systems produced PMMA polymer with varying behaviors [7,[20][21][22][23][24][25]. The careful choice of material and curing technique is critical to confirm the best product in prosthodontic treatments [26]. Developing the polymerization protocols led to promising enhancements in the performance of dental composites [27].…”

Novel Cold Cure Acrylic Denture Base with Recycled Zirconia Nano-Fillers That Were Functionalized by HEMA Agent Incorporation: Using the Sprinkle Approach

“…However, the fundamental difference is the step of polymerization initiation at room temperature. 6 Regarding this step, in all PMMA polymers used in dentistry, there is a small percentage of a peroxide catalyst. This peroxide is broken into free radicals by heat, which catalyses the polymerization reaction.…”
