摘要/Abstract

摘要： 目的：采用全程数字化设计（CDD）技术对1例保留完整轴面形态的牙体缺损者的患牙进行冠修复，探索更为精准可行的牙体缺损修复方案。方法：患牙行根管治疗术后，仅牙合面充填树脂，轴面形态相对完整。为保留牙体预备前原始牙冠形态，采用CS3500口内扫描仪行口内扫描，利用软件中的生物复制（Biogeneric Copy）功能获得牙齿外形的数字化信息并转换，采用3D胶体沉积技术制作"釉锆"修复体。戴入后观察修复体的形态、近远中邻接关系及咬合情况，调查患者的舒适度及满意度。结果：修复体轴面外形与牙体预备前天然牙的形态一致，邻接关系和咬合关系恢复良好，患者对修复体满意，且无不适感和异物感。结论：采用CDD技术复制备牙牙冠形态制作修复体，可实现更精准、个性化的牙齿修复治疗。

Abstract: Objective:To fabricate an all-ceramic crown which copies the morphology of preoperative tooth in one patient with only small occlusal dentin defects with completely digital design(CDD) technology, and to find a more precise and feasible solution to fix the tooth detect. Methods:The tooth treated with root canal therapy had the complete axial surface and small occlusal dentin defects. In order to keep the morphology of preoperative tooth, the digitized crown was designed with the information of preoperative tooth by oral scanning with CS3500 and using the "Biogeneric Copy" function of exocad design software, then the digitized information of the teeth was collected and transformed and the simulate zirconia crown was mode by 3D colloidal deposition technique. The patient's comfort and satisfaction were investigated by observing the morphology, the interproximal contacts, and the occlusion of crown. Results:The morphology of definitive restoration was similar to the preoperative tooth, which presented good interproximal contact and occlusion, and the patient was greatly satisfied without discomfort and foreign body sensation. Conclusion:A more accurate and personalized restoration approach can be implemented with the application of CDD to fabricate new ceramic crowns which copy the preoperative tooth.
