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。提示ＨＡ涂层钛种植体作正畸支抗可满足种植体与颈部组织结合良好的要求
Hydroxyapatite (HA) -coated titanium implants were implanted into the dog jaws for postoperative implants. The orthodontic force of 150g was applied to dynamically analyze the gingival bleeding index, plaque and calculus within 3 months after bearing the implants Index, degree of loosening, peri-implant pocket depth and cervical bone mass change. The results showed that the implants were stable, soft tissue around the implant had slight inflammation, but no significant absorption of cervical bone tissue, cervical bone mass on the pressure side and tension side of no difference. Tip HA-coated titanium implants for orthodontic support to meet the implant and neck tissue with good requirements
