摘要
多生牙是常见需要拔除的额外牙。对于埋伏多生牙而言,如何在术中快速、精确定位,实现高效、安全、微创拔除一直是临床需要攻克的难题。影像学、数字化技术和材料学的发展为精准微创拔除该类牙齿提供了可能。基于患者的锥形束计算机断层扫描影像和计算机三维模型,利用数字化手段设计和制作的导板作为“桥梁”直接将手术设计方案应用到真实手术中,可极大地缩短手术时间,减小手术创伤,降低手术风险。本文结合现有导板辅助拔除埋伏多生牙的文献,就数字化导板的原理、应用现状作一综述,并对未来的发展进行展望。
Supernumerary teeth are extra teeth that need to be extracted.Achieving an efficient,safe and minimally invasive extraction with rapid and precise intraoperative location determination has been a clinical challenge in extracting embedded supernumerary teeth.Advances in imaging,digital technology and materials science could realise the accurate and minimally invasive extraction of such teeth.Based on the patient’s cone beam computed tomography image and computerised 3D modelling,the digital template acts as a‘bridge’that helps in the application of a surgical design to the real surgery directly,which could greatly shorten the surgery time,reduce the trauma and decrease the risk.The aim of this review was to summarise the functional realization of the template-guided extraction of embedded supernumerary teeth and the current application of digital guides and explore its future development trend.
