Modified tandem appliance for early correction of class III malocclusion – A case report

Abstract

Class III malocclusion is associated with a sagittal malrelationship of the maxilla and the mandible, characterized by a deficient maxilla, retrognathic mandible, or a combination of both. The early treatment of Class III malocclusions provides facial balance, modifies the maxillofacial growth and development, and prevents future surgical treatment by increasing the stability. Many treatment approaches can be found in the literature regarding orthopedic and orthodontic treatment of Class III malocclusion, including intra‑ and extra‑oral appliances. The major problem with extraoral anchorage has been of patient compliance due to its physical appearance. The case report presents an intraoral modified tandem appliance for maxillary protraction that has been used clinically to achieve successful results without relying much on patient co‑operation.
