【摘要】：背景:硬腭黏膜是牙周整形手术中结缔组织瓣的主要来源,其厚度是影响手术效果的关键。目的:分析中国汉族人群硬腭黏膜厚度,并比较CBCT图像分析法与探查法的测量一致性。方法:共招募30位汉族志愿者,总计300个牙位,使用CBCT图像分析法和探查法分别测量硬腭黏膜厚度,并分析两种方法的一致性。结果与结论:(1)CBCT法测和探查法测得尖牙、第1前磨牙、第2前磨牙、第1磨牙及第2磨牙的硬腭黏膜厚度具有较高的一致性;(2)随着距离龈缘的距离增加硬腭黏膜逐渐增厚;(3)从尖牙到第2磨牙不断增厚,在尖牙处最薄,到第2磨牙处达到最厚;(4)研究首次测量中国汉族人群硬腭黏膜厚度,并证明探查法与CBCT图像分析法具有较高的一致性。
[Abstract]:Background: hard palate mucosa is the main source of connective tissue flap in periodontal plastic surgery. Objective: to analyze the thickness of hard palate mucosa in Chinese Han population, and to compare the consistency between CBCT image analysis and exploratory method. Methods: a total of 300 teeth were recruited from 30 Han Chinese volunteers. The thickness of hard palate mucosa was measured by CBCT image analysis and probing method, and the consistency of the two methods was analyzed. Results and conclusion: (1) the thickness of hard palate mucosa in the first premolars, the second premolars, the first molars and the second molars was consistent with the CBCT method. (2) with the increase of the distance from gingival margin to the gingival margin, the hard palate mucosa gradually thickened. (3) from the canine to the second molar, the thickness was the thinnest at the canine and the thickest at the second molar. (4) the thickness of hard palate mucosa in Chinese Han population was measured for the first time, and it was proved that the exploratory method was in good agreement with the CBCT image analysis method.
