Curve of Spee - maintenance of the curve before surgery in lower dental arch and its impact on vertical parameters and esthetic results after surgery

Abstract

The impact of preserved Spee curve in the lower dental arch prior to surgery on the esthetics of the lower third of face in patients with Class II and orthognathic advacement of the mandible is studied. It was hypothesized that in patients with preserved Spee curve the vertical parameters would increase and mental protuberance would be less prominent after surgical management.
