To evaluate the loss of crestal bone height around dental implants placed in various tissue biotypes.
20 patients with single edentulous sites were allocated randomly, with 10 samples in each into Group I (implants were placed in thick tissue biotype) and Group II (implants were placed in thin tissue biotype). Baseline cone-beam computed tomography (CBCT) was performed after implant placement in both groups, and follow-up CBCT was taken at the time of cementation prior to occlusal loading to assess the crestal bone loss around the mesial and distal side of implants in both groups.
A significant loss of crestal bone at both the distal and mesial sides of the implants at the time of cementation was observed in both groups but Group II showed more crestal bone loss as compared to Group I.
Mean crestal bone loss was more in Group II (thin tissue biotype) in comparison to Group I (thick tissue biotype). The thick biotype causes less crestal bone changes than the thin biotype, which evokes more loss of crestal bone during the period of peri-implant healing.
评估植入不同组织生物型的牙种植体周围嵴顶骨高度的丧失情况。
20名单颗牙缺失患者被随机分配，每组10例样本，I组（种植体植入厚组织生物型）和II组（种植体植入薄组织生物型）。两组在种植体植入后均进行基线锥形束计算机断层扫描（CBCT），并在咬合加载前粘结时进行随访CBCT，以评估两组种植体近中和远中侧周围的嵴顶骨吸收情况。
两组在粘结时均观察到种植体远中和近中侧嵴顶骨有明显吸收，但II组与I组相比显示出更多的嵴顶骨吸收。
与I组（厚组织生物型）相比，II组（薄组织生物型）的平均嵴顶骨吸收更多。厚生物型比薄生物型引起的嵴顶骨变化更少，薄生物型在种植体周围愈合期间引起更多的嵴顶骨丧失。
