The successful esthetic integration of a prosthesis is dependent on the anatomic site in which the restoration is inserted. Edentulous site enhancement is a regenerative approach based on the following: (1) anatomic evidence that the morphology of soft tissues is dependent on the underlying support (bone, roots, implants) but also significantly influenced by overlying structures (fixed or removable prostheses); (2) histologic evidence of the remarkable regenerative capacity of the newly formed tissue that develops during healing by secondary intention; (3) clinical evidence that it is possible to guide the formation of this new regenerative tissue by creating a support with proper morphology and a highly polished surface; (4) observations that positive pressure exerted by alimentary bolus and negative pressure produced by deglutition affect the growth of this tissue healing by second intention; and (5) the application of appropriate oral hygiene techniques to guide tissue healing and maintain its integrity. The edentulous site enhancement approach is simple, practical, and predictable and offers minimal postoperative complications. This paper describes the edentulous site enhancement approach as applied in the pontic areas.
假体的成功美学整合取决于修复体植入的解剖部位。无牙区增强是一种基于以下几点的再生方法：（1）解剖学证据表明软组织的形态取决于其下方的支撑结构（骨、牙根、种植体），但也受到上方结构（固定或可摘修复体）的显著影响；（2）组织学证据表明二期愈合过程中形成的新组织具有显著的再生能力；（3）临床证据表明通过创建具有适当形态和高度抛光表面的支撑结构来引导这种新的再生组织形成是可行的；（4）观察发现食团施加的正压和吞咽产生的负压会影响二期愈合的这种组织的生长；（5）应用适当的口腔卫生技术来引导组织愈合并维持其完整性。无牙区增强方法简单、实用且可预测，术后并发症极少。本文描述了无牙区增强方法在桥体区域的应用。
