摘要: 正颌外科是通过外科手术与口腔正畸联合治疗,由于先天的生长发育异常或者后天的外伤等引起的单纯正畸不能解决的牙颌面畸形。颌面部血供丰富,解剖结构复杂,正颌手术术中常发生出血多、神经血管损伤、牙根损伤等各种并发症。为了降低这些并发症的发生率,以及使术后颌骨达到精确稳定的理想位置,正颌手术需使用各类导板[1]来辅助手术。传统导板制作流程复杂、误差大、耗时多。近年来,随着计算机辅助外科技术(CAS)的发展,运用数字化技术可以打印出不同的导板。数字化导板因拥有高精确性,能显著缩短手术时间,具有传统导板无法比拟的优点,目前被广泛应用到正颌外科手术中。本文就近年来数字化导板在正颌外科中的应用作一综述。

Abstract: Orthognathic surgery is a treatment procedure with a combination of surgical operation and orthodontic principles in the reconstruction of congenital or acquired abnormalities in the dentomaxillofacial region. The maxillofacial structure is very rich in blood supply with complex anatomical variations. Operation hemorrhage, neurovascular injury, injury to the root apices of the tooth and other complications often occur during orthognathic surgery .In order to reduce the incidence of these complications and to achieve postoperative accurate and stable ideal jaw position, orthognathic surgery procedure needs a variety of guides (surgical template) to assist . However, the production process of traditional guide plate is complex and there are high chances of error. With the development of Computer Aided Surgery (CAS) in recent years, more and more guide plates can be printed by digital technology. The digital guide plate has been applied to orthognathic surgery more frequently due to the advantages of high accuracy and short operation time than those traditional guides. In this paper, the advances of application of digital template in orthognathic surgery in recent years is reviewed.
