背景：组织生物型与牙周和种植体治疗的结果有关。本研究的目的是确定牙龈和下牙槽骨的尺寸在上颌前部region.Methods：组织生物型的22个新鲜的尸体头进行了评估临床和放射学与锥形束计算机断层扫描（CBCT）扫描。上颌前牙无创拔除。由两名校准检查员使用卡尺测量软组织和骨的厚度，精确至0.1 mm。在两个点（中唇和中腭）测量探测深度和牙龈退缩。临床和CBCT测量的软组织和骨厚度随后进行了比较和correlated.Results：没有统计学显着差异，观察到临床和CBCT测量的软组织和骨厚度，除了腭部软组织测量。唇侧牙龈厚度与CBCT测量的基底骨厚度中度相关（R = 0.429; P
Background: Tissue biotypes have been linked to the outcomes of periodontal and implant therapy. The purpose of this study is to determine the dimensions of the gingiva and underlying alveolar bone in the maxillary anterior region and to establish their association.Methods: Tissue biotypes of 22 fresh cadaver heads were assessed clinically and radiographically with cone-beam computed tomography (CBCT) scans. Maxillary anterior teeth were atraumatically extracted. The thickness of both soft tissue and bone were measured using a caliper to the nearest 0.1 mm by two calibrated examiners. Probing depths and gingival recession were measured at two points (mid-labial and mid-palatal). Clinical and CBCT measurements of both soft tissue and bone thickness were subsequently compared and correlated.Results: No statistically significant differences were observed between the clinical and CBCT measurements of both soft tissue and bone thickness except the palatal soft tissue measurements. The labial gingival thickness was moderately associated with the underlying bone thickness measured with CBCT (R = 0.429; P
