Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this research is to compare the diagnostic accuracy in the detection of the cementoenamel junction (CEJ) and alveolar bone ridge using guided digital planning versus conventional analog planning for patients with excessive gingival exposure in the smile (gummy smile) due, at least in part, to altered passive eruption.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Forty-four subjects will be randomly assigned to the planning groups according to a digital methodology, DM (n=22) or an analog methodology AM (n=22). Surgical guides will be developed to establish the location of the acementoenamel junction and bone crest. The digital methodology will consist of obtaining a digital scan and a computed tomography (CBCT) that will be aligned using a digital program for the elaboration of a digital wax-up and fabrication of a printed surgical template. The analog wax-up will be elaborated based on a silicone impression and periapical radiographs with parallel technique, which will allow us to elaborate an essix type surgical splint. Measurements will be recorded at baseline, on the day of surgery, at 4, 6 and 12 months of follow-up. Variables related to the patient's experience will also be recorded.
