ALL-on-4种植即刻修复并发症的初步探讨

目的 通过对ALL-on-4种植即刻修复并发症的追踪分析探讨其可能的原因及预防措施.方法 选取2014年3月-2016年6月收治的5例患者,共30颗种植体,半口缺失3例,全口缺失2例.患者均在术后24~48 h内带上临时修复体,6个月后完成最终修复体,平均追踪18个月.结果 30颗种植体有29颗至最后一次复查时稳定,有1颗在术后1个月松动后取出重新植入,种植体存活率为96.7%.术后有3例患者曾患有并发症,发生率为60%.结论 牙列缺失患者在完成ALL-on-4种植修复后存在较高的机械性并发症和生物性并发症的可能,作为医生应从其发生的原因着手通过主动地实施预防措施来降低并发症的发生.

A preliminary study on the immediate repair complications of ALL-on-4 planting

Objective To explore the possible reasons and precautionary measures through the tracing analysis on the complications occurring in ALL-on-4 implant prosthesis. Methods 5 cases of patients hospitalized from Mar 2014 to Jun 2016 were selected with a total of 30 implant,3cases of half-mouth teeth missing,2 cases of whole-mouth teeth missing.Patients wearing temporary prosthesis within 24-48 h postoperation and accomplishing final prosthesis 6 months later were followed up for 18 months medially. Results Among the 30 implants,29 were stable at the last review,one was re-implanted for its looseness after 1month.The survival rate of dental implant was 96.7%.There were 3 cases of patients with complications with the occurrence rate 60%. Conclusions As for the dentition defect patients,after the accomplishment of ALL-on-4 implant prosthesis,there is a relatively high possibility in the occurrence of mechanical complication and biological complication.From the perspective of doctors,the proactive precautionary measures should be conducted in order to reduce the complication occurrence,beginning with exploration of its cause.
