摘要:

微创牙髓治疗(minimally invasive endodontics,MIE)能够较大程度保存牙体组织,提高牙髓治疗成功率,受到越来越多的关注。3D打印技术是一种以数字模型为基础,运用粉末状金属、塑料等材料,通过逐层打印的方式来构造物体的技术。本文对3D打印技术在微创牙髓治疗中的应用进行综述,为今后3D打印技术应用于临床微创牙髓治疗提供参考。近年来,3D打印技术已广泛应用于颌面外科、修复学和正畸学等领域。通过利用锥形束CT(cone beam CT,CBCT)、口腔扫描仪等获取精确的牙齿内外部结构数据,结合3D打印制作牙齿诊断模型、开髓导板,能够精准定位根管位置,为微创牙髓治疗提供新方式。目前,3D打印技术在微创牙髓治疗领域中主要用于引导开髓通路、辅助畸形牙和钙化根管的微创治疗、辅助根尖外科手术等方面,但其精确性以及临床预后效果仍需要大量临床病例来验证。

Abstract:

Minimally invasive endodontics (MIE) can preserve dental tissue to a greater extent and improve the success rate of endodontics and has thus attracted increasing attention. 3D printing is a technology that is based on a digital model and uses powdered metal, plastic and other materials to construct objects by printing layer by layer. This article reviews the application of 3D printing technology in minimally invasive endodontics to provide a reference for the application of 3D printing technology in clinical minimally invasive endodontics in the future. In recent years, 3D printing technology has been widely used in various professional fields of stomatology, such as maxillofacial surgery, prosthodontics, and orthodontics. Using cone beam computed tomography (CBCT) and oral scanners to obtain accurate data on the internal and external structures of teeth combined with 3D printing to construct a tooth diagnostic model and pulp opening guide plate, we can accurately locate the position of the root canal and provide a new method for minimally invasive endodontics. At present, 3D printing technology is mainly used to guide the pulp opening pathway, assist in the minimally invasive treatment of malformed teeth and calcified root canals, and assist with apical surgery in the field of minimally invasive endodontics. However, its accuracy and clinical prognosis still need to be verified with a large number of clinical cases.
