SANCHEZ-TITO, Marco Antonio  and  YANEZ-CHAVEZ, Emerson Elecsi. Association between facial biotipe and overbite: Pilot study. Rev. Estomatol. Herediana [online]. 2015, vol.25, n.1, pp.05-11. ISSN 1019-4355.

Objective: To determine the association between facial biotype and the degree of overbite. Methods: The sample consisted of 152 students, aged 12-17, with their permanent dentition. Frontal photographs were taken of the students in natural head position. Face opening angle was determined based upon printed photographs in order to establish facial biotypes. Vertical overbite was measured using a Vernier caliper and a dermatograph pencil. Results: Distribution of facial biotypes in the sample was 80.3 per cent for dolichofacials, followed by a 19.7 per cent for mesofacials, with no brachyfacial types found. Among dolichofacials, a normal overbite was found to be predominant (55.7%), followed by a deep bite (36.9%), and an open bite (7.4%). Among mesofacials, a normal overbite was the most frequent finding (63.3%), followed by a deep bite (33.3%), and an open bite (3.3%). No statistically significant association was found (P> 0.05). Conclusions: Since results show no specific patterns, we conclude that facial biotypes are not associated with the degree of vertical overbite.
