项目摘要

Since many types of implants have been commercially available for orthodontic anchorage, each clinician have to pay attention to the following factors such as implant materials, implant size, implant site, expected loading term, magnitude of expected orthodontic load, periodontal conditions and age of the patient.On the other hand, many animal studies have been reported in the areas of implant-anchored orthodontics. The osseointegration between titanium implant and the surrounding bone are demonstrated to be essential for skeletal anchorage in most studies. However, we sometimes feel inconvenient for tight osseointegration at the time of implant removal, when bone of the implant site are very compact or the prolonged retention of the implant has occurred. On the contrary, insufficient osseointegration often cause loosening or failure of the implant.According to my Beagle studies, the osseointegration between titanium implant and surrounding bone could be changed due to implant size, implant site, duration of the implantation, and even age of the dog. Many clinicians understand that the osseointegration in the maxilla is less than those in the mandible in general. The osseointegration with large implant is greater than those with small implant. However, most clinicians do not necessarily pay attention to the loading timing after implantation.This study clearly demonstrated the osseointegration with different type, size and site of the titanium mini-screw and time-course study of mini-screw for osseointegration using adolescent, adult and aged Beagle dogs.

由于已有多种类型的植入物可用于正畸锚固，因此每个临床医生都必须注意以下因素，例如植入物材料，植入物尺寸，植入物，预期负载期限，预期正畸负荷，牙周牙周牙周质状况和年龄的幅度。在大多数研究中，钛植入物与周围骨骼之间的骨整合对于骨骼锚定是必不可少的。但是，当植入物部位的骨头非常紧凑或植入物的长时间保留时，有时我们会感到不便在植入物去除时紧密的骨整合。相反，骨整合不足通常会导致植入物的松动或失败。根据我的贝格（Beagle）研究，由于植入物的大小，植入物，植入的持续时间，植入持续时间，甚至狗的年龄，可能会改变钛植入物和周围骨骼之间的骨整合。许多临床医生了解到，上颌骨的骨整合度通常比下颌骨少。具有大植入物的骨整合性比具有小植入物的骨整合性大。但是，大多数临床医生不一定要注意植入后的加载时间。这项研究清楚地证明了使用青少年，成人和年龄的Beagle犬的骨螺钉的不同类型，大小和位点的骨整合和不同类型，大小和位点以及小型螺旋的时间课程。
