摘　　要：目的 探讨EAM医用树脂和羟基磷灰石（EH）型复合材料结合计算机辅助设计/计算机辅助制作（CAD/CAM）技术治疗单侧小下颌畸形的临床效果.方法 对12例因各种原因导致小下颌畸形的患者,根据其特征和要求,借助CAD/CAM技术以对侧为参考,快速成型还原出下颌骨不对称畸形的部位与范围,通过三维结构设计、重建,将EH复合骨水泥翻制、复原成相应的形状,植入手术区域.结果 除1例因伤口裂开取出外,其余11例患者EH型复合材料与下颌骨贴合,形态自然,外形恢复满意.结论 EH型复合材料结合CAD/CAM技术,可个性化改善颌骨的不对称畸形,为治疗单侧小下颌畸形提供了新的途径.Objective To evaluate the clinical efficacy in the treatment of unilateral micrognath ia by using EAM medical resin and hydroxyapatite （EH） composite material combined with the CAD/ CAM technique.Methods From July 2011 to October 2015,12 cases of unilateral micrognathia caused by different reasons were treated,based on the representative traits and requirements,refering to the unsymmetric counter part by right of CAD/CAM technique.By the 3-dimensional design and reconstruction,we reformed the EH composite material into purposed shape,and insert it in the operative area.Results All the materials were closely suitable to the mandible surfaces.1 case failed because the wound was torn apart;the other 11 patients recovered more than 6 months and were satisfied with the external appearance.Conclusions The EH composite materials combined with CAD/ CAM techniques could be a potential characterized remedy for the unilateral micrognathia.
