摘　　要：目的:利用CBCT测量老年人上颌前牙区唇侧软组织的厚度,获取其厚度值,建立老年人上颌前牙区唇侧软组织厚度数据库,分析其与性别的相关性,为临床中进行前牙区牙周治疗及种植修复等美学治疗提供参考依据和指导。方法:选取60例符合要求的老年人,进行CBCT扫描并三维方向重建,在牙体长轴矢状位剖面进行测量,在唇侧选取五个点进行软组织厚度测量(距离龈缘1mm、2mm,牙槽嵴顶,牙槽嵴顶根方1mm、2mm)。结果:受试者中切牙在五处软组织测量点的厚度分别为(0. 90±0. 04)mm、(1. 23±0. 12)mm、(1. 48±0. 09)mm、(0. 60±0. 10)mm、(0. 67±0. 04)mm,侧切牙分别为(0. 78±0. 03)mm、(1. 02±0. 10)mm、(1. 29±0. 04)mm、(0. 51±0. 09)mm、(0. 59±0. 04)mm,尖牙分别为(0. 86±0. 04)mm、(1. 10±0. 09)mm、(1. 44±0. 04)mm、(0. 56±0. 05)mm、(0. 62±0. 05)mm。结论:上颌前牙区唇侧软组织厚度在同一牙位不同位点处存在差异,表现为牙槽嵴顶处最厚,龈边缘到牙槽嵴顶处的软组织截面形态近似于三角形,不同牙位在同一位点处也存在显著性差别,表现为中切牙区>尖牙区>侧切牙区;侧切牙区唇侧软组织厚度男性均大于女性,但仅在龈缘处差异具有显著性(P<0. 05),中切牙及尖牙区唇侧软组织厚度在性别间无统计学差异(P>0. 05)。Objective:CBCT was used to measure the thickness of labial soft tissue in the maxillary anterior teeth of the elderly,and to obtain the thickness of the soft tissue of the labial side of the maxillary anterior teeth.To provide reference and guidance for aesthetic therapy of periodontal treatment and implant repair in anterior teeth.Methods:Sixty elderly patients who met the requirements were selected for CBCT scanning and 3d reconstruction.Measurement was conducted in the direction of the long axial sagittal position of the tooth.Then and the soft tissue thickness was measured at five points on the labial side(1,2 mm from gingival margin,alveolar crest,alveolar crest root square 1,2 mm).Results:The thickness of incisors at five soft tissue measurement points was(0.90±0.04)mm、(1.23±0.12)mm、(1.48±0.09)mm、(0.60±0.10)mm、(0.67±0.04)mm,respectively.The parameters of lateral incisors was(0.78±0.03)mm、(1.02±0.10)mm、(1.29±0.04)mm、(0.51±0.09)mm、(0.59±0.04)mm.The parameters of canine was(0.86±0.04)mm、(1.10±0.09)mm、(1.44±0.04)mm、(0.56±0.05)mm、(0.62±0.05)mm.Conclusion:The thickness of the labial soft tissue in the maxillary anterior teeth area was different at different points in the same tooth location,which was manifested as the thickest at the top of the alveolar crest.The profile shape of the gingival tissue from the gingival margin to the top of the alveolar crest was approximately triangular.There were also significant differences in soft tissue thickness between different tooth positions at the same location,which were manifested as the central incisor area﹥the canine area﹥the lateral incisor area.The thickness of the labial soft tissue in the lateral incisors was greater in males than in females,but the difference was significant only at the gingival margin,and there was no statistical difference between male and female in the central incisors and the canines.
