Abstract Background. Altered passive eruption occurs due to excessive gum overlapping the enamel. These cases can be handled with a crown lengthening surgery. Modern digital technologies enabling guided gingivectomy with or without removing the underlying supporting bone can help the clinician in achieving predictable and desired results. Objective of the study. To demonstrate a possible digital workflow in aesthetic crown lengthening procedures through a clinical case. Material and Methods. The patient examination revealed the presence of short clinical crowns. A crown lengthening procedure with bone resection was planned. Cone-beam computed tomography (CBCT), intraoral scanning, and 3D printing were used to design and print a single surgical guide, that provided a reference for both gingivectomy and osteoectomy during the guided aesthetic crown lengthening procedure. Results. After 6 months, the patient was satisfied with the aesthetic result, presenting an absence of visible gingival excess, adequate crown height, with no recurrence of disease. Conclusion. The proposed digital workflow can be successfully implemented in case of periodontal aesthetic procedures. Predictable results, harmonious relationship between dental and gingival shapes and dimensions can be achieved using modern digital technologies.
