Treatment option for a "peg lateral" in cross bite : A Case Report

Anterior cross bite is one of the most common orthodontic problems that we observe in growing children. Anterior cross bite usually occurs in the primary and mixed dentition as a result of disharmony in either the skeletal, functional or dental components of the orthognathic system. This case report is of a 15year old boy in permanent dentition with maxillary right peglateral in crossbite. A removable Hawley appliance with Z-spring and posterior bite plane was fabricated for the treatment. The peglateral was built up with acid-etch composite resin. The patient was cooperative and the cross bite was treated in 15 days with good positive overbite.Keywords: Peglateral, Anterior cross bite, Hawleys appliance, Z-spring, Posterior bite plane, Acid-etch composite.
