种植体表面处理与骨结合效应:3i种植系统的临床应用

Surface preparation of dental implant and osseointegration:Clinical application of 3i implant system

背景：种植义齿已逐渐成为牙列缺损或缺失的常规修复方式,目前国内外采用的种植系统众多,在临床应用效果上各有特点。目的：观察经双重酸蚀或Nano Tite表面处理的3i种植系统对牙列缺损或缺失的修复效果。方法：95例患者植入双重酸蚀的OSSEOTITE种植体150枚（植入后1~3个月行永久修复）,植入Nano Tite种植体7枚（植入后1个月行永久修复）。随访观察24个月,行临床检查及影像学检查对临床效果进行评价。结果与结论：157枚种植体骨结合良好,种植体根周未见X射线透射区;随访期内,所有种植体均未见松动、脱落,留存率100%,成功率100%,无种植体宿主不良反应。提示经双重酸蚀或Nano Tite表面处理的种植体有利于引导成骨细胞趋化,修复效果满意。

BACKGROUND：Implant denture has been the conventional restoration means of dentition defect and edentulous gradually.A variety of implant systems are applied domestically and abroad with respective clinical effects.OBJECTIVE：To investigate the clinical effects of 3i implant system with double-etched surface preparation.METHODS：Ninety-five patients were selected as subjects.A total of 157 3i implants were implanted after contraindications to dental implantation were excluded.In view of various conditions of the soft and hard tissues in edentulous area,different surgical techniques were adopted accordingly.Permanent restorations were finished 1 to 3 months after the implantation.The following period was 24 months.Clinical effects were evaluated through clinical and imaging examination.RESULTS AND ONCLUSION：Favorable osseointegration was formed rapidly and no X-ray radiolucent area around the implants was observed in 157 implants.There was no implant loosening or shedding.High degree of satisfaction from patients was achieved.Both the survival rate and successful rate of implants were 100%.Implants with double-etched surface preparation facilitate the osteoblasts chemotaxis and osseointegration.3i implants system could be considered as a anageable and effective implant system with shorter treatment course.
