The iliac bone graft procedure is one of the treatment options for individuals with extremely resorbed alveolar bones. An autogenous block bone graft can allow the use of an implant-supported fixed dental prosthesis, rather than conventional removable dentures, by completely edentulous patients. However, the iliac bone graft technique is an invasive procedure and should be carefully selected based on its long-term clinical results. This case report describes 11-year long-term outcomes for implant-supported complete denture on the grafted iliac bone.
A 68-year-old Asian man was referred for oral rehabilitation with fixed dental prostheses. The patient had been unsatisfied with his removable dental prostheses in masticatory performance.
Radiographical examination revealed severely atrophied maxilla.
The atrophied maxilla was reconstructed with an iliac block bone graft, after which an implant-supported fixed complete denture was placed.
During 11 years of follow-up, several prosthetic and mechanical complications were encountered. Nevertheless, no biological complications were observed. Marginal bone levels around the implants were well-maintained on the radiographs after 11 years of prosthetic use.
Iliac bone graft can be chosen as a predictable treatment option that allows patients with extremely atrophic maxilla to use a fixed dental prosthesis instead of a removable denture.
髂骨移植手术是牙槽骨极度吸收患者的治疗选择之一。自体块状骨移植可使全口无牙患者使用种植体支持的固定义齿,而非传统的可摘义齿。然而,髂骨移植技术是一种侵入性手术,应根据其长期临床效果谨慎选择。本病例报告描述了在移植髂骨上种植体支持全口义齿的11年长周期结果。
一名68岁的亚洲男性因固定义齿进行口腔修复前来就诊。患者对其可摘义齿的咀嚼性能不满意。
影像学检查显示上颌骨严重萎缩。
用髂骨块状骨移植对上颌骨萎缩进行重建,之后植入种植体支持的固定全口义齿。
在11年的随访期间,出现了一些修复和机械并发症。然而,未观察到生物并发症。义齿使用11年后,影像学检查显示种植体周围的边缘骨水平保持良好。
髂骨移植可作为一种可预测的治疗选择,使上颌骨极度萎缩的患者能够使用固定义齿而非可摘义齿。
