Objective:
The conventional anterior esthetic treatment protocol is limited as it's time consuming and unreliable. A predictable digital workflow for minimally invasive anterior esthetic tooth rehabilitation with global diagnosis principle has been introduced in this report.
Clinical Considerations:
A 23-year-old female patient with the chief complaint of unsatisfied shape and color of her anterior teeth visited our hospital for restorative consultation. Three-dimensional Digital Smile Design was used to integrate into a virtual patient model to provide rehabilitative esthetic planning with global diagnostic principle. 3D printer was used for communication and guidance preparation. Digital impression and computer-aided design/computer-aided manufacturing technologies were adopted for making the morphology of designed restorations that can precisely transfer to definitive prostheses. The esthetics, functional occlusion, and gingival tissues remained stable for over a follow-up period of 3 years. No signs of fractures within the restorations were observed.
Conclusions:
Minimally invasive anterior esthetic tooth rehabilitation can be readily achieved using a predictable digital workflow with global diagnosis principle.
Clinical Significance:
This digital approach might promote diagnosis, enhance communication, reduce processing time, and increase the predictability of final outcomes with high comfort and esthetic effect.
