摘要
为了挽救、保存牙齿,对27个牙周病患牙(18个牙周牙髓联合病变,9个牙周炎)进行了牙髓腔-骨内种植术,用TA2或TC4作植入体,经1～34月观察,6牙显效,15牙好转及6牙无变化。为观察植入体在骨组织中的情况,对一狗的2(?)2作了牙髓腔-骨内种植术,(?)用TA2,(?)用TC4作植入体。17月后处死动物,取植入体,用电子显微探针分析,发现两种植入体上均有来自机体骨组织的钙元素附着;组织学检查植入区亦均有结缔组织管腔形成,而于TC4管腔的底部与侧壁有骨样组织形成。
TA2 and TC4 endodontic-endosseous implants were used in 27 teeth (18 teeth with periodontic-endodontic combined lesion, and 9 with periodontitis). After a period of observation (1-34 months), it was found that 6 teeth showed prominent improvement, 15 were improved and 6 had no change. For the purpose of observation of the condition of implants in the bones, endodontic-endosseous implantationwas performed in two teeth of a dog (2 with TA2 and 2 with TC4). Seventeen months after implantaion, the animal was Killed and the teeth implaateol were removed from the alveoli. It was found by electronic microscopic observation that there was some calcium from the Lone tissue attached to TA2 and TC4. Histological examination of the surrounding tissues (HE stain), found connective tissue barriers and some osteoid tissue was found at the bottom of TC4 implant canal and lateral walls.
