目标修复体空间指导多学科联合治疗精准修复1例

冠、桥修复需要对基牙进行定量调磨，如何更加精准地进行牙体的定量预备是微创修复追求的目标之一。本文报道1例上、下颌侧切牙先天缺失的病例，以目标修复体空间（TRS）为指导，在正畸、牙周多学科联合治疗后，制作个性化牙体预备数字化导板辅助精准牙体预备，完成固定桥修复，最终为患者恢复了上颌牙列的完整、美观和功能。该病例提示，在TRS指导下，牙体预备数字化导板能有效提高牙体预备的准确性。

A case of precise prosthesis under the direction of target restoration space analysis after multidisciplinary combination therapy

Quantitative grinding of abutment teeth is needed in crown and bridge restoration. Accurate quantitative preparation of teeth is one of the goals of minimally invasive restoration. In this paper, a case of congenital loss of upper and lower incisors was reported. Guided by the target restoration space (TRS), a personalized digital guide plate for tooth preparation was built to assist precise tooth preparation after the multidisciplinary combination therapy of orthodontic and periodontal teeth. Finally, the fixed bridge was prepared to meet the integrity, beauty, and function of the maxillary for the patient. In this case, the results suggest that the digital guide plate built under the guidance of TRS can be used to improve the accuracy of dental preparation.
