Peri-implant marginal mucosa defects (PMMDs) are alterations of the peri-implant soft tissue architecture characterized by an apical discrepancy of the mucosal margin respective to its ideal position with or without exposure of transmucosal prosthetic components or the implant fixture surface. PMMDs may not only represent an esthetic concern but also predispose to biofilm accumulation and subsequent initiation and progression of peri-implant inflammatory diseases. A treatment-driven classification for tooth-bound, facial PMMDs in non-molar sites, consisting of three different levels of complexity, is proposed. Clinical recommendations pertaining to the prosthetic and surgical management of each type of PMMD, illustrated with practical examples, are provided with the purpose of facilitating decision-making processes in daily practice.
种植体周围边缘黏膜缺损（PMMD）是种植体周围软组织解剖结构的改变，其特征为黏膜边缘相对于其理想位置的根尖方向差异，伴有或不伴有穿黏膜修复体部件或种植体表面的暴露。PMMD 不仅可能是美学方面的问题，还可能导致生物膜积聚，随后引发和进展种植体周围炎症性疾病。提出了一种针对非磨牙部位的、基于治疗的、针对牙支持的、面侧 PMMD 的分类方法，该方法包含三个不同复杂程度的级别。提供了与每种 PMMD 类型的修复和手术管理相关的临床建议，并结合实际病例进行了说明，旨在为日常实践中的决策过程提供便利。
