Correction of lip suction and transverse development in mixed dentition

Abstract

Introduction:  An increased horizontal overbite is a type of dental malocclusion in which the teeth of the maxillary bone protrude notably in the sagittal direction over the teeth of the mandibular bone. This malocclusion has different etiologies, among them, parafunctional habits, among which is the habit of lip sucking. Objectives:  Correction of the lip habit, treat transverse development and reduce increased overjet. Case description:  11-year-old male patient, who presented for consultation "Because he sucks his lip." Clinically, lip sucking habit, lack of transverse development and increased overjet are observed. Diagnosis: Ricketts and Jarabak told us that this is a skeletal and dolichofacial class II patient, who also has mandibular retrognathism. Steiner gives us a clockwise rotation that confirms class II. Treatment:  As a result of the cephalometrics obtained, analysis of study models and photographs, the treatment was divided into two phases. In the first, a Hawley-type plate (upper) was placed, and in the lower arch Schwartz modified with Lip Bumper, to treat the habit of lip sucking. As a second phase of treatment, Hawley-type plates were used in both arches, so that in this way the lack of transverse development would be worked on. Conclusions:  The timely attention and correction of parafunctional habits in pediatric patients, allows the redirection of growth and therefore a more harmonious and functional craniofacial development. It is important to perform an evaluation of the clinical characteristics of our patient, thus determine its etiology and treat it.
