| 摘 要： | 将羟基磷灰石涂层钛种植体处期植入狗颌骨，以施以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，种植体颈周深度及颈中骨量变化。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。

| Abstract: | 12 two-stage HA-coated 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 peri-implant soft tissue displayed slight inflammation, but no marginal bone absorption 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 HA-coated titanium implants are satisfactory when the implants are used as anchorage for short-term orthodontic treatment. |
