This case report shows how using digital wax-up and a printed model to get more predictable results while performing esthetic crown lengthening than the free hand approach.


A 21-year-old female patient presented to the clinic to have her short lateral incisors elongated. A 3D digital wax up was created by the student dentist and it was determined the short lateral incisors would need to be lengthened in a gingival direction. A 3D model of the was up was printed. Using the 3D printed model, a clear essix vaccufom material was used to create a guide for the gingivectomy part of the crown lengthening. Following gingivectomy, a flap was reflected on both lateral incisors and the bone was reduced. The patient received provisional veneers and was seen for the last follow up a month after the surgical procedure.


The patient was satisfied with the esthetic result of the surgical and restorative procedures despite not receiving the final veneers yet


Using 3D-printed models and digital wax up leads to more reliable surgical execution of esthetic crown lengthening procedures
