摘要
将羟基磷灰石（ＨＡ）涂层钛种植体延期植入狗颌骨，施以１５０ｇ的正畸力，动态分析支抗种植体受力后３个月内的牙龈出血指数，菌斑、牙石指数，松动度，种植体颈周袋深度及颈部骨量变化。结果显示：种植体均稳固，种植体周围软组织有轻微炎症，但颈部骨组织无明显吸收，颈部骨量在压力侧与张力侧的变化无差异。
12 twostage HAcoated titanium implants placed in dogs' mandibles were loaded with an orthodontic force of 150 g for 3 month. Gingival bleeding index, plague and calcucus index, mobility index, probing depth and marginal bone were investigated. The results showed that the implants were stable and periimplant soft tissue displayed slight inflammation, but no marginal bone absorpation and no difference of bone quantity between the tension side and compression side were found. It can be concluded that the clinical trials of marginal tissue around the HAcoated titanium implants are satisfactory when the implants are used as anchorage for shortterm orthodontic treatment.
