Abstract
Since Class III malocclusion is progressive in nature, the facial growth of Class III malocclusion worsens with age. Class III malocclusion is associated with a deviation in the sagittal relationship of the maxilla and the mandible, characterized by a deficient maxilla, retrognathic mandible, or a combination of both. The early orthopedic treatment of Class III malocclusions, at the end of primary dentition or the beginning of mixed dentition, prior to growth spurt, allows the accomplishment of successful results, providing facial balance, modifying the maxillofacial growth and development, and in many instances, preventing a 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.
