种植修复大于1年,碟形骨吸收至种植体平台下3 mm时,应选择翻瓣植骨

Flap surgery is required when “saucer-like” marginal bone loss amounts to 3 mm below implant shoulder after 1-year loading

在口腔种植临床工作中,各种原因导致的种植体周围骨吸收是一种常见的临床问题。然而,在对于碟形骨吸收的处理上,还缺乏统一的认识和标准。本文结合历史文献以及最新的共识性论述,提出当种植体修复时间超过1年,碟形骨吸收至种植体平台下3 mm时,患者处于一种较危险,并极有可能满足种植体周围炎的病理性状态当中。本文总结认为,处于这一病理状态下的患者需要进行翻瓣植骨的治疗。

Peri-implant bone resorption resulting from various causes is a common clinical problem in the clinical work of oral implantology.Whereas,there is a lack of a unified understanding and standard regarding saucer-like bone resorption.To make a comprehensive understanding of this situation,this article reviewed recent literatures and consensus reports,demonstrating that under the pre-described situation(the repair time surpasses one year and“saucer-like”marginal bone loss amounts to 3 mm below the implant shoulder,patients might be in a dangerous pathological condition close to peri-implantitis.To achieve stable long-term outcomes,an open flap debridement and regenerative treatment are required.
