三维成像与计算机辅助软件在单侧牙槽突裂的应用进展

牙槽突裂植骨术是牙槽突裂修复的金标准,随着唇腭裂患者及其家属对牙列美观度要求的提升,该手术在唇腭裂序列治疗中日益受重视,而精确并快速地测量术前牙槽突缺损体积、协助外科手术及评估术后移植骨组织吸收率,是目前牙槽突裂植骨术研究的热点及难点。三维CT是骨组织评估的可靠检查工具,已有实验对单侧牙槽突裂植骨术前后的三维图像进行研究分析。计算机辅助工程(CAE)技术逐渐用于协助三维图像的测量与评估。通过阐述近年来三维成像与计算机辅助软件在牙槽突裂的研究及应用,归纳总结牙槽突裂治疗中,三维成像与传统二维成像的优缺点及计算机辅助软件在单侧牙槽突裂中的应用。

Application progress of 3D imaging and CAS in unilateral alveolar cleft

Alveolar cleft bone grafting is the gold standard of alveolar cleft repair.With the enhancing of requirements of patients with cleft lip and palate and their family members for dentition beauty,this surgery obtains more and more attention in sequence treatment of cleft lip and palate.How to accurately and quickly measure the damage volume of alveolar process defect before operation,and assist with surgery and assess the absorptive rate of bone graft tissue after operation are the hot and difficult points in the study of bone grafting of alveolar cleft at present.Three dimensional computed tomography(3D-CT)is a reliable examination tool of assessing bone tissue.At present,there are many experiments to study and analyze the 3D image of unilateral alveolar cleft before and after operation.In addition,more and more computer-aided engineering(CAE)technique has been used to assist the measurement and assessment of 3D image.Through states the research and application of 3D imaging and computer-aided software(CAS)in alveolar cleft at recent years,this paper summarizes the advantages and disadvantages of 3D imaging and 2D imaging,and the application of CAS in unilateral alveolar cleft in the treatment of alveolar cleft.
