摘要
为探讨羟基磷灰石（ＨＡ）涂层钛种植体作为正畸支抗的可行性，将ＨＡ涂层钛种植体植入狗颌骨内，施以１５０ｇ正畸力，采用Ｘ线照片定位测量及种植体周围临床指征的动态观察，了解支抗种植体的稳定性、颈部软组织健康状况及颈部骨量变化。结果显示：种植体无松动、脱落，不移动；颈部软组织存在轻微炎症，但对颈部骨组织无影响，骨量未发生改变。提示ＨＡ涂层钛种植体可作为支抗用于短期的口腔正畸治疗。
This study was aimed at the feasibility of using HA coated titanium endosseous implants as orthodontic anchorage. These implants installed in dog's mandibles were loaded with the orthodontic force of 150g for 3 months. The stability of the implant and the peri implant neck tissue were investigated with radiograph and index evaluation. The findings demonstrated that no implant was mobile or loose or dislocated. The soft tissue around the cervical part of the implants had a slight inflammation because of bad oral hygiene and the stimulation of residual food attached to the stainless string. However, no resorption of marginal alveolor bone was found under sustained orthodontic force. The above results suggest that the HA coated titianium implant can be used as anchorage for short term orthodontic treatment.
