Objective: This article describes a digital dental esthetic ceramic veneer treatment workflow using a stereolithographic template for teeth preparation.
Clinical Considerations: We have presented the case of a 33‐year‐old woman with dental fluorosis who wanted an esthetic ceramic veneer treatment. A digital smile design was created on a virtual patient, and a virtual diagnostic wax‐up was made. Based on the suggested ceramic material thickness, virtual teeth preparation was performed on the diagnostic wax‐up. A special‐teeth preparation template was then created digitally and fabricated using a stereolithographic technique. This template guided the teeth preparation using a special bur with a stopper. The veneers were fabricated by CAD/CAM and delivered good esthetics and function.
Methods: An intraoral scanner (3Shape TRIOS, Denmark) and a face scanner (3dMD, The United States) were used for intraoral and face scans, respectively.
Conclusions: The stereolithographic tooth reduction template helps realize digital restorative planning. It provides better control of the reduction depth of the labial and incisal preparation, making the operation simpler.
Clinical Significance: The digital dental esthetic ceramic veneer treatment workflow described here using a stereolithographic template for teeth preparation helped with the accurate control of reduction depth for minimally invasive teeth preparation, making the operation simpler, which is a significant improvement over the previous methods.
