Acrylic resin, based on PMMA chemistry, is a thermoplastic material that can be easily moulded and processed using various techniques, such as heat-curing, cold-curing and microwave curing. These versatile and quick processing methods make PMMA a popular choice throughout the dental industry.
In terms of aesthetics, pigmented PMMA closely mimics the appearance of natural gingiva and is available in various shades to match a wide range of patient gingival tones (Gad, Fouda, Al-Harbi, & Näpänkangas, 2018). Moreover, PMMA is biocompatible and has suitable mechanical properties to ensure patient comfort and safety. (Shah, Bansal, & Logani, 2015).
