Here is described a modified technique of palatomaxillary reconstruction that combines the use of a free vascularized bone graft by osteotomy, soft-tissue flap, zygomatic implant as an anchorage and two standard implants simultaneously. The patient presented with deformity in the left face after subtotal maxillectomy (Brown 2b classification). Preoperative work up was performed by a rapid prototyping model using computer-aided manufacturing technology. The purpose of this model is to provide accurate measurements of the defect. The palatomaxillary three-dimensional buttress system can be managed by orienting the bone graft vertically and horizontally. Reconstruction of the palatomaxillary defect was successfully accomplished in a single surgical procedure. Dental implant restoration achieved good osseointegration without any significant resorption. This new modification represents a significant contribution to palatomaxillary reconstruction using zygomatic implants as anchorage.
本文介绍了一种改良的腭上颌重建技术,该技术同时结合了通过截骨术使用游离带血管骨移植、软组织瓣、作为锚固的颧骨种植体和两个标准种植体。该患者在次全上颌骨切除术后出现左侧面部畸形(Brown 2b分类)。术前通过使用计算机辅助制造技术的快速成型模型进行评估。该模型的目的是提供缺损的精确测量。通过垂直和水平定向骨移植可以管理腭上颌三维支撑系统。在一次外科手术中成功完成了腭上颌缺损的重建。牙种植修复实现了良好的骨整合,没有任何明显的吸收。这种新的改良为使用颧骨种植体作为锚固的腭上颌重建做出了重大贡献。
