作者采用本组研制的致密型生物活性陶瓷(生物活性玻璃陶瓷和锆——羟基磷灰石陶瓷)作立即牙根种植共68例、139颗。患者在局麻下拔牙,形成粘骨膜瓣,根据离体牙根及X线牙片选择人工牙根,植入牙槽窝内,颌端位于牙槽骨缘下2mm,便于血凝块形成。术后定期作临床及x线片观察,结果表明:该材料的生物相容性好,3～6个月后人工牙根周围有明显的新骨形成,种植体与牙槽骨的界面结合牢固,人工牙根稳定且无形状改变,牙槽嵴无明显吸收,故提高了义齿修复的效果。本法操作简单,效果显著。
The authors used the group developed compact bioactive ceramic (bioactive glass ceramic and zirconium - hydroxyapatite ceramic) for immediate rooting a total of 68 cases, 139. Patients under local anesthesia extraction tooth, the formation of mucoperiosteal flap, according to isolated root and X-ray dental prosthesis root, implanted in the alveolar fossa, the maxillary alveolar bone edge located 2mm, ease of blood clot formation. The results of regular clinical observation and x-ray examination showed that the material has good biocompatibility, obvious new bone formation around the artificial root after 3 to 6 months, and the interface between the implant and the alveolar bone is firm, Artificial root stability and no shape change, alveolar ridges no significant absorption, it improves the effect of denture repair. This method is simple, the effect is remarkable.
