The increased emphasis on physical appearance in contemporary society has increased the demand for esthetic dental restorations. Although the success of implant dentistry has expanded the scope of esthetic fixed prostheses, many patients demand a removable partial denture (RPD) for health, anatomic, psychological, or financial reasons. Fabricating an esthetically pleasing RPD while avoiding the unsightly display associated with conventional clasp assemblies often presents a challenge to dentists. This article examines using lingual clasps, proximal undercuts (also known as rotational path insertion), and acetal resin clasps as simple and effective means of improving RPD esthetics.
当代社会对身体外观的日益重视增加了对美观牙齿修复体的需求。尽管种植牙科的成功扩大了美观固定修复体的范围，但由于健康、解剖、心理或经济原因，许多患者仍需要可摘局部义齿（RPD）。在制作美观的RPD时，避免传统卡环组件带来的不雅外观往往给牙医带来挑战。本文探讨使用舌侧卡环、近中倒凹（也称为旋转就位道）和缩醛树脂卡环作为改善RPD美观的简单有效方法。
