摘要
逆行性种植体周围炎(RPI)是指在种植体植入后短期内出现的伴随临床症状的根尖周病变,而种植体冠方骨结合良好。RPI是种植义齿的一种特殊并发症,是导致种植失败的重要原因之一。其病因复杂多样,主要包括细菌感染、无菌性骨坏死、种植区骨愈合不良、早期过度负载等几个方面。治疗方法类似于天然牙根尖周病的治疗,包括邻牙根管治疗、外科清创术、种植体根尖切除术、引导性骨组织再生术(GBR)以及全身应用抗生素。术前全面检查术区及邻牙病变,术中严格规范手术操作可以有效避免术后RPI,提高种植体的成功率。
Retrograde peri-implantitis is defined as a clinically symptomatic periapical lesion that develops shortly after implant insertion in which the coronal portion achieves a normal osseointegration.RPI is a special complication of dental implants and it is one of the major reasons of dental implants failure. The etiology of RPI seems to be multifactorial,which may primarly comprise bacterial infections,aseptic necrosis of bone,poor bone quality of the implant site,premature or excessive load.The treatment protocols is approximately similar to periapical periodontitis of the natual teeth , which may largely comprise the endodontic treatment of the adjacent teeth, sufficient debridement, resection of the implant apex,GBR and systemic antibiotic.Comprehensive preoperative examination of the insertion site and adjacent teeth ,and strict operation could effectively reduce the chances of RPI,which can improve the success rate of dental implants.
