Summary

Maxillary transverse deficiency is an orthodontic anomaly characterized by the upper and lower dental arches being incompatible due to insufficient width of the maxilla. This condition typically manifests with clinical symptoms such as crossbite, crowding of teeth, and impaired respiratory function. Genetic factors, early primary tooth loss, mouth breathing, thumb sucking, and abnormal swallowing are among the causes of maxillary narrowing. Treatment options vary depending on the patient's age and the degree of suture closure. In pediatric and adolescent patients, rapid (RPE) or slow (SPE) orthodontic expansion can be achieved with palatal expansion appliances. However, in adult patients, due to the less flexible bone structure of the maxilla, methods such as surgically assisted expansion (SARME) or mini-screw-assisted expansion (MARPE) are preferred. Recent studies have shown that MARPE can be effective as a non-surgical alternative in young adults and can provide direct skeletal expansion without damaging the teeth.

Conditions

  • Maxillary Expansion
  • Maxillary Transverse Deficiency

Interventions

DEVICE

MARPE (Mini-Screw Assisted Rapid Palatal Expansion)

A mini-screw assisted rapid palatal expansion device used to achieve skeletal maxillary expansion through bicortical anchorage. The device delivers orthopedic forces to the maxillary sutures with reduced dental tipping and greater skeletal effects compared to conventional rapid palatal expansion appliances.

PROCEDURE

SARME (Surgically Assisted Rapid Maxillary Expansion)

A surgically assisted maxillary expansion procedure performed to facilitate skeletal expansion in skeletally mature patients. The procedure involves weakening areas of resistance in the maxilla (e.g., lateral walls, midpalatal suture) followed by activation with a rapid palatal expansion device to achieve transverse maxillary widening.
