Background: In patients with gingival exposure on smiling due to altered passive eruption, esthetic crown lengthening is often indicated. Meticulous planning and surgical precision are key for successful outcomes. Surgical guides are helpful tools that are seldomly reported on in the literature related to esthetic crown lengthening procedures., Types of Studies Reviewed: The authors searched the literature for articles that described the planning, tools, and execution related to esthetic crown lengthening procedures., Results: Several techniques have been reported to guide the esthetic crown lengthening procedure, ranging from direct bone level measurement to 3-dimensional printed surgical guides., Practical Implications: This review serves the clinician as an aid in the decision-making process for esthetic crown lengthening procedures and available surgical guide options, including computer-based guides., (Copyright © 2022 American Dental Association.

Featured Application: When no prosthetic treatment is indicated, esthetic crown lengthening can be facilitated by fabricating a 3D printed surgical guide based on CBCT measurements and an intra oral scan. Excessive gingival display is a common clinical presentation that often requires surgical intervention. This report is for a patient for whom esthetic crown lengthening is indicated due to altered passive eruption. Cone beam computed tomography (CBCT) scan and an intraoral scan were used to design and print a single surgical guide which provided a reference for both gingivectomy and osteoectomy. A satisfactory outcome was obtained 6 months after surgery. The present technique provided a simplified method of generating a surgical guide with predictable results by relying on the existing tooth anatomy rather than diagnostic waxing. This technique is particularly useful when crowns or veneers are not indicated. [ABSTRACT FROM AUTHOR]
