Abstract

One of the most often used bone augmentation techniques is the guided bone regeneration procedure. The authors report the case of a 75-year-old man with an atrophic right posterior mandible who underwent bone augmentation through guided bone regeneration with a preshaped titanium mesh adapted on a stereolithographic model of the patient's jaw. The graft volume was simulated with a light-curing resin. The actual site was grafted with a mixture of autogenous and equine-derived bone. Five months later, the mesh was retrieved, three cylindrical implants were positioned, and a bone biopsy was collected for histomorphometric analysis. A provisional prosthesis was delivered three and a half months later. Definitive rehabilitation was accomplished after one additional month. The graft allowed for effective bone formation (newly formed bone, residual biomaterial, and medullar spaces were, respectively, 39%, 10%, and 51% of the core volume). The patient has functioned successfully throughout six and a half years of follow-up. Using the preshaped titanium mesh in association with the enzyme-treated equine bone substitute provided effective bone regeneration.

摘要

最常用的骨增量技术之一是引导骨再生术。作者报告了一例75岁男性患者,其右侧下颌骨萎缩,通过引导骨再生术进行骨增量,使用了根据患者颌骨的立体光刻模型定制的预成型钛网。用光固化树脂模拟移植骨体积。实际部位植入了自体骨和马源骨的混合物。五个月后,取出钛网,植入3枚圆柱形种植体,并采集骨活检样本进行组织形态计量学分析。三个半月后安装临时义齿。再过一个月完成最终修复。移植骨实现了有效的骨形成(新形成的骨、残余生物材料和骨髓腔分别占核心体积的39%、10%和51%)。在六年半的随访期间,患者功能良好。使用预成型钛网联合酶处理的马骨替代物可实现有效的骨再生。
