In recent years, the dimensions of different parts of the masticatory mucosa have become the subject of considerable interest in periodontics from both an epidemiologic and a therapeutic point of view. In the present article, the clinical relevance of the thickness of the masticatory mucosa for the development of gingival recessions, surgical root coverage, as well as graft harvesting will be reviewed. The concept of different periodontal phenotypes has recently been substantiated by experimental evidence using a novel, commercially distributed, ultrasonic measuring device. Based on observations made in a series of investigations, it has become clear that individuals with thin and vulnerable gingival tissue prone to the development of recession often also present with thin palatal mucosa that might not be very suitable for obtaining connective tissue of proper thickness for plastic periodontal surgery. Periodontal phenotypes are closely associated with, and are in fact an expression of, the so-called biologic width, which should be considered during subgingival placement of restorations in particular. Thus, a detailed analysis of the thickness of the masticatory mucosa may be necessary in several clinical situations.
近年来，从流行病学和治疗学的角度来看，咀嚼黏膜不同部位的尺寸已成为牙周病学中相当受关注的主题。在本文中，将对咀嚼黏膜厚度在牙龈退缩、手术性牙根覆盖以及移植取材方面的临床相关性进行综述。不同牙周表型的概念最近已通过使用一种新型的、商业销售的超声测量设备的实验证据得到证实。基于一系列研究中的观察结果，很明显，牙龈组织薄且易发生退缩的个体通常也存在腭黏膜薄的情况，这可能不太适合获取用于牙周整形手术的合适厚度的结缔组织。牙周表型与所谓的生物学宽度密切相关，实际上是其一种表现形式，在进行龈下修复体放置时尤其应予以考虑。因此，在几种临床情况下，可能有必要对咀嚼黏膜的厚度进行详细分析。
