摘要
目的利用锥形束CT(cone bone computed tomography,CBCT)对上颌前牙区腭侧黏膜厚度进行测量分析,了解其分布规律,为临床上上颌前牙区腭侧瓣的制取提供参考。方法选取2019年1—12月就诊于本院因治疗需要拍摄CBCT且符合纳入标准的患者130例,对中切牙、侧切牙、尖牙腭侧距离龈缘3 mm、6 mm、9 mm的黏膜厚度进行测量。利用SPSS 23.0软件,分析比较左右侧黏膜厚度分布;不同牙位,不同水平的分布以及不同性别、年龄、腭穹隆中黏膜厚度的差异。结果约2.1%的位点黏膜厚度小于2 mm;左右两侧的对应位点的黏膜厚度基本呈现对称分布;同一牙位黏膜厚度随着与龈缘距离而变化;在距离龈缘同一距离水平上,不同牙位黏膜厚度不同;不同性别之间的黏膜厚度无差异;不同年龄段以及腭穹隆形态的黏膜厚度在大多数位点存在一定差异。结论在生理状态下,上颌前牙区腭侧黏膜基本呈对称分布;黏膜厚度随着与龈缘距离的增加而逐渐增厚;从前至后依次增厚;性别对黏膜厚度的影响甚微;年长者的黏膜多厚于年轻者;高腭穹隆者的黏膜多厚于低腭穹隆者。
Objective To measure the palatal mucosal thickness in the maxillary anterior region by CBCT,and to understand its distribution features and provide reference for manufacture of palatal lateral flap of maxillary anterior region in clinic.Methods From January to December 2019,130 cases of patients those admitted to our hospital and needed CBCT examination and conform to the inclusion criteria were enrolled in the study.The mucosal thickness of palatal sides which were 3 mm,6 mm and 9 mm from the gingival margin of the central incisor,lateral incisor and canine were measured.SPSS 23.0 software was used to analyze and compare the distribution of left and right mucosal thickness.The distribution of different dental positions and different levels,and differences in mucosal thickness of different gender,age,and the palatal vault were also compared.Results Among all measured sites,the proportion of mucosal thickness less than 2 mm was about 2.1%.The mucosal thickness of the corresponding sites on the left and right sides showed a symmetrical distribution.The mucosal thickness of the same tooth position changed with the distance from the gingival margin.At the same distance from the gingival margin,the thickness of the mucosa was different in different teeth.There was no significant difference in mucosal thickness between different genders.There were some differences in mucosal thickness between different age groups and palatal vault morphology at most sites.Conclusions Under the physiological condition,the palatal mucosa in the maxillary anterior region showed a symmetrical distribution.The mucosal thickness gradually thickened with the increasing distance from the gingival margin and thickened from front to back.Gender had little effect on mucosal thickness.The mucosa of the elderly is thicker than that of the youth.The mucosa of the high palatal vault is generally thicker than that of the low palatal vault.
