文题释义:
热塑性义齿基托树脂:即用于制作口腔活动义齿基托的热塑性树脂,主要分为注射成型热塑性义齿基托树脂和传统热固化聚甲基丙烯酸甲酯;与热固化聚甲基丙烯酸甲酯树脂相比,注射成型热塑性义齿基托树脂生物相容性高,不易致敏;文章介绍的注射成型热塑性义齿基托树脂目前被报道有5种,在牙科领域主要用于制作隐形义齿。
注射成型:这是区别于聚甲基丙烯酸甲酯树脂热固化成型的另一种成型方式,其成型温度比较高,达到150 ℃以上,热塑性义齿基托树脂加热成流动状态后,注射到特定的模具中,冷却成个性化隐形义齿。
 
 
背景:随着人们对义齿美观性要求越来越高,以注射成型热塑性义齿基托树脂制作的非金属卡环义齿(也被称为隐形义齿或弹性义齿)以其优异的美观性、良好的柔韧性和生物相容性在牙科领域得到越来越多的应用。
目的:综述注射成型热塑性义齿基托树脂的种类、性能及临床应用。
方法:第一作者检索PubMed、Wiley、Springer、OVID、ScienceDirect、Google 学术数据库和CNKI数据库,英文关键词为“Polyamide AND denture,thermoplastic denture base resin,non-metal clasp denture,nylon,flexible denture”,中文关键词为“弹性义齿,弹性树脂基”,文献时间限定在1955年1月至2017年4月。

结果与结论:注射成型热塑性树脂材料众多,目前被报道可作为义齿材料的主要有以下5种:聚酰胺、聚碳酸酯、聚酯、丙烯酸树脂及聚丙烯,他们具有弹性高、适合性好、美观、不易断裂等优点,因此临床上可用于制作注射成型热塑性义齿基托;但这种材料存在颜色不稳定、细菌易黏附、不易抛光和重衬等缺点,因此需要进一步改进材料的性能。

Abstract:

 BACKGROUND: With the increasing demands on the aesthetics of dentures, non-metal clasp dentures (also known as concealed dentures or flexible dentures) that are made of injection-molded thermoplastic denture base resins, have been popularized in the dental field due to their excellent aesthetic performance, good flexibility and biocompatibility.

OBJECTIVE: To review the types, properties and clinical applications of injection-molded thermoplastic denture base resins.
METHODS: The first author searched PubMed, Wiley, Springer, OVID, ScienceDirect, Google and CNKI databases for relevant articles published from January 1955 to April 2017 using the key words of “polyamide AND denture, thermoplastic denture base resin, non-metal clasp denture, nylon, flexible denture” in English and Chinese, respectively.

RESULTS AND CONCLUSION: There are five main types of injection-molded thermoplastic denture base resins used as denture materials, including polyamides, polycarbonates, polyesters, acrylics and polypropylenes, which have good elasticity, suitability, beauty and biocompatibility and can be widely used in the dental field. However, further improvement in the performance of injection-molded thermoplastic denture base resins is warranted, including unstable coloring, bacteria adhesion and difficulty in material polishing and relining.
