摘要

传统上,义齿基托是用热固化丙烯酸树脂制造的。这种树脂于1936年首次用于牙科实验室,这是一个巨大的进步。由于其孔隙率增大、吸水率高、聚合收缩、单体残留致敏性和毒性、封瓶包装不方便、加工难度大等缺点,人们不断寻找替代品。开发了无单体和高冲击丙烯酸树脂,并经历了义齿基托镀金,以便为过敏患者提供替代选择。随着聚合物的发展,新型树脂,如聚酰胺(尼龙)、缩醛、环氧树脂、苯乙烯、聚碳酸酯、乙烯基、聚氨酯、聚醚醚酮(PEEK)等,伴随着现代技术,如注射,在牙科市场上出现。CAD/CAM铣削和3D打印义齿基地代表了目前在这个领域的艺术状态。本章旨在介绍这些替代材料,这些材料在过敏患者的情况下可以安全使用,并保证健康的口腔环境和高度的舒适度。

Alternative Denture Base Materials for Allergic Patients
Traditionally, a denture base is manufactured using a heat-cured acrylic resin. This type of resin was first used in dental labs in 1936, being a great step forward. Because of the many disadvantages as increased porosity, high water sorption, polymerization shrinkage, allergenic potential and citotoxicity due to the residual monomer, awkward flasking and packaging, and difficult processing, alternatives were continuously searched. Monomer-free and high-impact acrylics were developed, and gold plating of the denture base was experienced, in order to provide an alternative to allergic patients. Once polymers developed, new types of resins, such as polyamides (nylon), acetal, epoxy resins, styrene, polycarbonate, vinyl, urethane, polyether ether ketone (PEEK), became available on the dental market, accompanied by modern technologies, such as injection. CAD/CAM milled and 3D printed denture bases represent the present state of the art in this domain. Our chapter aims to present these alternative materials, which are safe to use in cases of allergic patients and guarantee a healthy oral environment and a high degree of comfort.
