K-Sir arch for simultaneous intrusion and retraction of the maxillary anterior teeth-A case report

This case report shows the management of Angle's Class II division 1 Malocclusion with tooth size-arch length discrepancy of − 10 mm in maxillary arch and mandibular arches, proclined upper and lower anteriors, and crowding in relation to lower anteriors. Clinical evaluation revealed Class II dental and skeletal pattern, low mandibular plane angle, incompetent lips, increased overjet and overbite. Simultaneous intrusion and retraction of upper anterior teeth using Kalra Simultaneous Intrusion and Retraction arch was decided due unaesthetic excessive maxillary incisor showing at rest and to provide maximum space for the retraction of anterior teeth. Posttreatment changes were good and stable.
