Aim: Increased vertical growth of maxilla is a condition that affects a large part of the population, which reveals a skeletal alteration of the cranio-masticatory system. One of the effects generated by excessive vertical growth of maxilla is a gingival smile pattern that, in addition to affecting aesthetic patterns, can alter the masticatory biomechanics, which is a primary etiological factor in temporomandibular dysfunction. Contemporary imaging aids help optimize diagnostic analysis, apply treatment, and make an evaluation before, during and after treatment. This study aims to compare the clinical diagnosis of gingival smile with the dimensions of the dentoalveolar square, digitally calculated in the panoramic projection of the cone beam tomography.
Materials and methods: a sample of 37 patients, an analysis of the correlation between the dimensions of the dentoalveolar square of Tatis panoramic cephalometry and clinical photometry was performed, applying Tjan’s gingival smile analysis.
Results: Results show that the cephalometric measurement method of the dentoalveolar square and Tjan’s photometric measurement method have high correlation and agreement. Both methods can be used to classify the smile type in high, medium, or low.
Conclusions: analysis of the dentoalveolar square of the panoramic cephalometry provides an accurate diagnosis of the anterior vertical dimension of the maxilla related to the clinical diagnosis of smile.
