Abstract

BACKGROUND

One-stage jaw reconstruction with fibular flap and prosthetic rehabilitation restores bony and dental continuity simultaneously. It was also called as "jaw-in-a-day (JIAD)" technique. However, bone volume and height of fibular flap may be insufficient for dental implant insertion. The provision of a considerable amount of bone makes an iliac flap the ideal choice in these cases. We present the first case report to document the use of one-stage jaw reconstruction and prosthetic rehabilitation with the iliac flap.

CASE PRESENTATION

We modified the conventional JIAD workflow to make it suitable for iliac flap. Two cases were presented who both underwent segmental mandibulectomy for ameloblastoma. Virtual surgical planning was performed in all cases. The iliac crest was positioned upward to provide cortical bone for achieving primary stability of dental implants. Similar to the "all-on-4" procedure, the iliac bone was placed 12 to 15 mm below the occlusal plane to create adequate space for the implant-retained prosthesis. Immediate implant-based dental rehabilitation was performed at same stage. The surgery was successful in all cases without any short-term complications. In the first postoperative week, patients were given a liquid diet through a nasal feeding tube. The liquid diet is advised until 1 month after the surgery. Thereafter, a soft diet is recommended. Patients were advised to resume routine mastication and normal diet 3 months after the surgery. Peri-implantitis occurred in one patient, and additional gingival graft was required. Postoperative function and esthetics were satisfactory at the last follow-up visit.

CONCLUSIONS

One-stage jaw reconstruction and prosthetic rehabilitation with the iliac flap are safe and useful for restoring postoperative function and esthetics. It should be used in more cases with a longer follow-up in further studies.

摘要

背景

采用腓骨瓣进行一期颌骨重建及修复体康复可同时恢复骨连续性和牙连续性。此技术也被称为“一日颌骨(JIAD)”技术。然而,腓骨瓣的骨量和高度可能不足以植入牙种植体。在这些情况下,提供大量骨组织使髂骨瓣成为理想选择。我们呈现首例使用髂骨瓣进行一期颌骨重建及修复体康复的病例报告。

病例介绍

我们对传统的JIAD工作流程进行了改良,使其适用于髂骨瓣。报告了2例均因成釉细胞瘤接受下颌骨节段性切除术的病例。所有病例均进行了虚拟手术规划。将髂嵴向上定位以提供皮质骨,以实现牙种植体的初期稳定性。与“all-on-4”手术类似,将髂骨置于咬合平面以下12至15毫米处,为种植体支持的修复体创造足够空间。在同一阶段进行即刻种植体支持的牙齿康复。所有病例手术均成功,无任何短期并发症。术后第一周,通过鼻饲管给予患者流食。建议流食持续至术后1个月。此后,推荐软食。建议患者在术后3个月恢复常规咀嚼和正常饮食。1例患者发生种植体周围炎,需要额外进行牙龈移植。在最后一次随访时,术后功能和美观效果令人满意。

结论

采用髂骨瓣进行一期颌骨重建及修复体康复对于恢复术后功能和美观是安全且有效的。在进一步研究中,应在更多病例中应用并进行更长时间的随访。
