The development of hypoallergenic denture resins is key to the treatment of patients with allergies to polymethyl methacrylate (PMMA). In this study, the in vitro mechanical properties of hypoallergenic and PMMA denture base resins were compared. Ninety-six test specimens of hypoallergenic denture base resins (Polyan Plus, Sinomer, TMS Acetal Dental, Erkocryl) and 72 test specimens of PMMA-based denture base resins (Paladon 65, PalaXpress, SR-Ivocap) were fabricated. The flexural strength, elastic modulus, compressive strength, macro- and microhardness, average roughness, water absorption, and water solubility of the resins were measured. None of the hypoallergenic denture resins matched all the mechanical properties of the PMMA resins. Polyan Plus and TMS Acetal Dental were closest to matching the mechanical properties of the PMMA resins, and TMS Acetal Dental had some superior properties. Consequently, Polyan Plus and TMS Acetal Dental hypoallergenic resins are recommended for further investigation as potential alternatives to PMMA resins for the fabrication of removable dentures.
低敏性义齿树脂的研发是治疗对聚甲基丙烯酸甲酯(PMMA)过敏患者的关键。在本研究中,对低敏性和PMMA义齿基托树脂的体外力学性能进行了比较。制备了96个低敏性义齿基托树脂(Polyan Plus、Sinomer、TMS Acetal Dental、Erkocryl)测试样本和72个PMMA基义齿基托树脂(Paladon 65、PalaXpress、SR-Ivocap)测试样本。测量了树脂的弯曲强度、弹性模量、抗压强度、宏观和微观硬度、平均粗糙度、吸水性和水溶性。没有一种低敏性义齿树脂能完全匹配PMMA树脂的所有力学性能。Polyan Plus和TMS Acetal Dental最接近匹配PMMA树脂的力学性能,且TMS Acetal Dental具有一些优越性能。因此,建议对Polyan Plus和TMS Acetal Dental低敏性树脂进行进一步研究,作为制作可摘义齿的PMMA树脂的潜在替代品。
