To present a digital workflow approach for the full-mouth rehabilitation of severely worn dentition and to evaluate the impact of vertical dimension of occlusion (VDO) rehabilitation on facial parameters assessed by 3D stereophotogrammetry throughout all treatment steps.
Extensive tooth wear frequently demands the determination of a new VDO for the prosthodontic treatment. While digital tools have been used to establish hybrid or fully digital workflows in prosthodontics, a validation of accuracy between the planification stage and final VDO, as well as resulting linear and volumetric changes in the soft tissues after treatment, has not been reported utilizing tridimensional facial reconstruction systems. The clinical report describes the case of a 34-year-old patient with generalized erosive tooth wear and severe tooth sensitivity. After diagnosis, the patient was treated with a minimally invasive digitally driven full-mouth rehabilitation using lithium-disilicate bonded restorations, and stereophotogrammetry was used for the evaluation of facial changes before, at the planning stage, and after VDO rehabilitation.
The fully digital workflow allowed for a predictable rehabilitation of the VDO, where similar stereophotogrammetric measurements were observed during the mock-up and at the end of the treatment. 3D stereophotogrammetry imaging allowed to quantitatively assess differences in facial appearance after VDO rehabilitation.
The conscious application of fully digital workflows enables predictable achievement of both functional and esthetic parameters in the rehabilitation of VDO. 3D stereophotogrammetry confirmed similar facial measurements between the initial condition, mock-up stage, and treatment outcome.
介绍一种用于严重磨损牙列全口修复的数字化工作流程方法,并评估在所有治疗步骤中,咬合垂直距离(VDO)恢复对面部参数的影响,该面部参数通过三维立体摄影测量法进行评估。
广泛的牙齿磨损常常需要确定用于修复治疗的新VDO。虽然数字工具已被用于在修复学中建立混合或全数字化工作流程,但尚未有研究利用三维面部重建系统报告在计划阶段与最终VDO之间的准确性验证,以及治疗后软组织产生的线性和体积变化。该临床报告描述了一名34岁患有广泛性侵蚀性牙齿磨损和严重牙齿敏感患者的病例。诊断后,患者接受了使用二硅酸锂粘结修复体的微创数字化驱动全口修复治疗,并使用立体摄影测量法评估VDO恢复前、计划阶段和恢复后面部的变化。
全数字化工作流程能够对VDO进行可预测的修复,在试戴阶段和治疗结束时观察到类似的立体摄影测量结果。三维立体摄影测量成像能够定量评估VDO恢复后面部外观的差异。
有意识地应用全数字化工作流程能够在VDO修复中可预测地实现功能和美学参数。三维立体摄影测量法证实了初始状态、试戴阶段和治疗结果之间面部测量结果相似。
