Clinical efficacy of EH composite material combined with CAD/CAM technique in plastic treatment of unilateral micrognathia

Objective To evaluate the clinical efficacy in the treatment of unilateral micrognathia 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.
