The possibility of placing dental fixtures in the reconstructed regions allows us to overcome the problems related to dental rehabilitation with removable prosthesis. The aim of this study was to assess the clinic-radiological outcome in a series of patients who underwent fibula flap jaws reconstruction and rehabilitation with implant-supported prosthesis with a minimum follow-up of 24 months.
The study included 10 patients who underwent reconstruction with fibula free flap between 2010 and 2018. Albrektsson criteria were used to define the implant survival. The follow-up evaluation was performed according to a standardized protocol including clinical examination, radiological evaluation (panoramic radiograph) and patient interview.
A total of 45 implants were positioned.The time between mandibular reconstruction and implant placement ranged from 13 months to 39 months.The prosthesis used was fixed in 6 cases and supported overdenture in 4 cases.No implant failure was observed.Regarding implant survival no infections were observed in these series. Nine patients out of 10 had no pain and signs of mobility. Seven patients out of 10 had absence of peri-implant radiolucency at the panoramic radiograph.One patient presented with an overgrowth of granulomatous soft tissue around the implant abutments that caused pain.
Implant placed in vascularized bone grafts are a safe and reliable opportunity to rehabilitate patients following mandibular resection. The results of this series demonstrate a high survival rate for implants placed in reconstructed mandibles with an improvement of the quality of life.
在重建区域中放置牙种植体的可能性使我们能够克服与可摘局部义齿修复相关的问题。本研究的目的是评估一组接受腓骨瓣颌骨重建和种植体支持修复体的患者的临床 - 影像学结果，随访时间至少为 24 个月。
本研究包括 2010 年至 2018 年间接受游离腓骨瓣重建的 10 例患者。使用 Albrektsson 标准来定义种植体的存活率。随访评估根据标准化方案进行，包括临床检查、影像学评估（全景片）和患者访谈。
共放置了 45 个种植体。下颌骨重建和种植体放置之间的时间间隔为 13 至 39 个月。使用的修复体为固定修复体 6 例，覆盖义齿修复体 4 例。未观察到种植体失败。在这些系列中，没有观察到与种植体存活相关的感染。10 例患者中有 9 例无疼痛和活动度迹象。10 例患者中有 7 例在全景片上无种植体周围骨透射。1 例患者出现围绕种植体基台的肉芽组织过度生长，导致疼痛。
在血管化骨移植物中放置种植体是一种安全可靠的机会，可以为下颌骨切除后的患者进行修复。该系列的结果表明，在重建下颌骨中放置种植体具有较高的存活率，可提高生活质量。
