“Changes in Nasolabial Angle, Lip Competency And Facial Profile By Correcting Angulation Of Maxillary Central Incisors” – A Case Report

Abstract

This case report evaluates the management of protrusion in a female patient with a Class I malocclusion with conventional fixed appliance . The case required extraction of 1st premolars for correction of the and forwardly placed upper and lower anterior teeth. we managed it without extractions by correcting just the angulation of the upper central incisors which drastically bought about an improvement in the patients smile, profile and aesthetics. Clinical and evaluation revealed skeletal Class I malocclusion with a convex facial profile, an average to horizontal growth pattern, an divergent face, increased and average overbite, severe jetting in the maxillary anterior region and mild crowding in the mandibular anterior region, potentially incompetent lips, increased lip fullness and lip strain and a decreased angle. Following fixed orthodontic treatment by changing the angulation of upper central incisors and with retraction of anterior segment, a marked improvement in patient's smile, facial profile and occlusion was achieved and there was a remarkable increase in the patient's confidence and quality of life. The profile changes and treatment results were demonstrated with proper case selection and good patient cooperation with fixed appliance therapy.
