Dental TechniqueFour-dimensional digital prediction of the esthetic outcome and digital implementation for rehabilitation in the esthetic zone

Technique
The treatment consisted of the restoration of defective and discolored anterior teeth caused by fluorosis.

Obtain 2D intraoral digital photographs and 3D digital dental casts. Make intraoral digital photographs by using a single-lens reflex camera (EOS 70D; Canon Inc) (Fig. 1A). Scan the maxillary and mandibular dentitions with the gingival tissues and the buccal sides of dentitions with the teeth in the maximum intercuspal position by using an intraoral scanner (TRIOS; 3Shape) to obtain 3D
Discussion
The presented digital technique promotes the visual perception and prediction quality of esthetic dentistry. This strategy can facilitate dentist–patient–technician communication and, subsequently, transfer the digitally designed shape of restorations to the definitive ceramic restorations. The authors are unaware of a previous report of this technique for predicting esthetic outcome, which integrates an intended diagnostic cast into the overall dynamic smiling process.

Summary
The technique described is applied for 4D prediction of the outcome of esthetic dentistry. The use of this technique could improve the simulation effect and visual reality of esthetic prediction before treatment.

2024, Journal of Prosthetic DentistryCitation Excerpt :The registration between two 3D facial images with the closed-mouth and registered-block impression positions was similar to the function of DGB2, which improved the registration accuracy by increasing the reference area but also increased the registration error.23 The larger deviation of the exposed anterior teeth group may have resulted from the accuracy of face scan and the limited registration reference area.2,5 During the registration process, the anterior teeth and first premolar were used as the registration reference area; this was clearer than the posterior teeth, resulting in differences being mainly located in posterior teeth, similar to the findings of Xiao et al.5

2022, Journal of Prosthetic DentistryCitation Excerpt :In a conventional workflow, it is expected but not ensured that the planned smile will be precisely transferred to the definitive restorations.9 Analog waxing from a 2D photograph of the patient may contain inaccuracies because the results depend mainly on the technician’s impression and expertise.31 The digital process overcome these concerns by combining imaging devices and a new 3D reconstruction software program.4,8,36
