【摘要】 与传统固定桥相比,使用树脂粘接固定桥的主要优点是能保存更多的牙体硬组织,从而实现微创牙科这一治疗理念。近年来氧化锆树脂粘接固定桥因其兼具美观和高强度等特点备受关注,但临床中修复体脱落是这一创新性修复技法的主要缺陷,因此,目前氧化锆粘接桥主要用于承受咬合力较小的前牙区。随着近年口腔材料学的发展,树脂粘接固定桥的成功率大大提高,同时高强度氧化锆代替金属材料使用在后牙成为可能。本文结合临床病例和文献探讨后牙氧化锆树脂粘接固定桥的设计和粘接技巧的要点及其原理。更多还原

【Abstract】 Compared with traditional fixed partial dentures,the main advantage of using resin-bonded fixed partial dentures(RBFPDs) include the preservation of dental hard tissues,following the concept of minimal invasive dentistry.In recent years,zirconia RBFPDs have garnered considerable attention because of their aesthetic and high strength.However,debonding has been the main disadvantage of this innovative technique.In consequence,zirconia RBFPDs are used mainly for anterior areas,which bear a small occlusal force.With the development of dental materials science,the use of high-strength zirconia to replace metal may become a trend.This paper investigates the design and bonding technique of posterior zirconia RBFPDs with a clinical case and literature review.更多还原
