影响纯钛种植体骨整合界面形成的临床因素分析

The effect of clinical factors on implant osseointegration formation.

目的 通过临床实践探讨影响钝钛种植体骨整合界面形成的因素 ,寻求防治措施 ,提高种植义齿的成功率。方法 对 2 30例门诊种植病人采用Branemark纯钛种植体行延期种植术 ,3～ 6个月后行Ⅱ期手术。结合X线及术中所见 ,评价钝钛种植体骨整合界面形成状况。结果 在植入的 5 2 0颗纯钛种植体中 ,获得骨整合界面的有5 0 3颗 ,失败 17颗 ,成功率 96 .7%。结论 影响纯钛种植体骨整合界面形成的因素有术前严格选择适应证及充分的术前准备 ,防止骨灼烧 ,预防感染 ,防止术中种植体被污染。

Objective To analyze the effect of clinical factors on implant osseointegration formation. Methods A clinical study using the Branemark dental implant system was carried out on 230 patients. The second stage procedure was performed at 3-6 months postoperatively. The status of implant osseointegration was assessed by X-ray and clinical examination. Result Among 520 dental implants inserted,503 dental implants acquired osseointegration, 17 implants failed to osseointegrate and the success rate was 96.7%. Conclusion The dental implant osseointegration formation depends on selecting indication,presurgical preparing, subtle surgical manipulation, and preventing bone burning, inflammation of operation aera and contamination of dental implants.
