Abstract

Edentulism causes aesthetic, functional, nutritional, phonetic and psychological damage. One of the best treatments for it is implant-supported full-arch prostheses. However, like all techniques, it involves challenges.

Aim: To evaluate the main complications in implant-supported complete dentures.

Materials and method: This study analyzed the medical records of 140 patients rehabilitated with implant-supported full-arch prostheses with immediate loading using the passive fit technique. The analysis considered the antagonist, and complication location (upper and/or lower jaw). All cases had 1 to 8 years under load.

Results: No complication was reported in 115 (82.1%) patients, while 25 presented complications: 14 (56%) prosthetic tooth fractures, 3 (12%) prosthesis retention screw fractures, 3 (12%) loss of cementation of the cylinder, and 5 (20%) implant losses. There were more complications in implant-supported complete dentures in the upper arch or cases of both jaws (p<0.05). The success rate (patients without complications during follow-up) was 82.1%.

Conclusion: Implant supported complete dentures made by the passive fit technique were predictable in the long term for rehabilitation of completely edentulous patients.

种植体支持全弓即刻修复的并发症：巴西回顾性、观察性、纵向研究。

蛀牙症造成审美、功能、营养、语音和心理上的损害。最好的治疗方法之一是种植全弓假体。然而，像所有的技术一样，它也有挑战。目的：评价种植全口义齿的主要并发症。材料与方法：本研究分析了140例采用被动配合技术采用即刻加载全弓种植体修复的患者的医疗记录。分析考虑了拮抗剂和并发症的位置（上颌和/或下颌）。所有病例的负荷均为1至8年。结果：115例（82.1%）患者无并发症，25例出现并发症：假牙骨折14例（56%），假体固定螺钉骨折3例（12%），假体椎体骨水泥丢失3例（12%），种植体丢失5例（20%）。结论：被动配合技术制作的种植全口义齿对全牙无牙患者的长期康复是可预测的。
