摘要
目的:种植体即刻负载技术有益于缩短种植手术与修复的"等待期",及时满足患者的美观和咀嚼要求,进一步扩大种植义齿临床适应症,本文旨在探讨该技术的适应症、操作技巧,评价其远期临床疗效。方法:CDIC种植体植入23例牙缺失患者,共植入49枚种植体,术后一周内完成上部结构修复,经检测种植体动度、GI及有无种植体周围炎、口腔全景片等指标,评价临床成功率。结果:随访1～6年,23例患者中,仅一例患者的一枚植体松动、脱落,其余种植体均获临床成功,临床成功率为97.96%。结论:即刻负载修复病例的选择应为牙槽嵴丰满之中青年患者,种植体周围应有足够的骨壁包绕,以增加种植体初期稳定性。从黏骨膜瓣环切至种植体窝洞预备,都应贯彻"宁小勿大"原则,增加种植体的嵌合能力。一期法、非翻瓣式手术有利于软组织愈合,减少种植体周围炎发生机率。前牙即刻加载修复时,多枚种植体的连冠(T-T)修复优于单枚种植体修复,后牙即刻加载适用于2颗以上的种植体支持式固定修复,可以分散力,增加稳定性。
Objective： Immdeiate loading of dental implant is benefit for reducing waiting period betwwn implant surgery and prosthesis. It could be used for restoration for cosmetic and masseteric fuctions, as soon as possible. The purpose of this study is to evaluate the clinical results of immediate loading of implant. Method： CDIC implants were useds by one-stae operation of 23 coses, including 49 implants. After one week, supper structures were restored. Primary stability, GI, peri-implantitis, panoramic x-rays films were analysed to determine the clinical resuhs. Result： After 1-6 year follow- up, 22 cases of 48 implants were remain. I implant was lost. The clinical successful rate is 97.96 %. Conclusion： Immediate implant technique is suitable for adequate alveolar bone of young patients. The bone around implant must be enough for good primary stability. From mucosa cut to bone drill, the diameter should be less than implant size. One-stage and flapless technique is benefit for wound healing of soft tissue, as well as for prevention of peri-implantitis. For anterior implants, T-T restoraion is better than single tooth. As posterior implants,implant-support prosthesis was recommeded for reducing bite force and incresing safety.
