Patients with traumatic dental injuries commonly present in clinical practice with complex crown-root fractures. Prosthodontic treatment of such patients may be unsuccessful because of the violation of the supracrestal tissue attachment, making their management challenging. Minor tooth movement is an effective solution to extruding the residual root but may require referral to an orthodontist. The purpose of this technique was to present a digital orthodontic system including a 3-dimensional virtual patient technique, a computer-aided design and computer-aided manufacture (CAD-CAM) resin facial veneer-retained pontic, and a zirconia post as an orthodontic appliance for tooth extrusion in the esthetic zone. This veneered pontic may also serve as an interim prothesis. The appliance provides a precise design for the direction and extent of orthodontic extrusion.

外伤性牙齿损伤患者在临床实践中通常表现为复杂的冠根骨折。此类患者的口腔修复治疗可能会因侵犯牙槽嵴顶组织附着而失败，这使得他们的管理具有挑战性。轻微的牙齿移动是挤压残根的有效解决方案，但可能需要转诊给正畸医生。该技术的目的是提出一个数字正畸系统，包括 3 维虚拟患者技术、计算机辅助设计和计算机辅助制造 (CAD-CAM) 树脂面部贴面保留桥体和作为正畸的氧化锆桩在美学区挤压牙齿的器具。这个贴面的桥体也可以作为临时修复体。
