Crown Lengthening in Aesthetic Anterior Sector by Means of Guided Digital Planning: Ramdomized Controlled Clinical Trial.
Trial Parameters
Brief Summary
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.
