Efficacy of Mini-implant Assisted Maxillary Expansion in Adolescents and Adults

Summary

Transverse maxillary deficiency is a common orthodontic issue, affecting around 10% of adults. Late adolescents and adults often require more force to expand the midpalatal suture due to its increased interdigitation. This study aims to assess the effectiveness of MARPE in this demographic and determine the best activation protocol for non-surgical maxillary expansion using mini-screw-supported appliances. Additionally, the study will evaluate the effectiveness of MARPE on nasal permeability and airway volume.

Conditions

  • Narrow Maxilla

Interventions

DEVICE

Mini-implants assisted maxillary expansion

The intervention involved the placement of orthodontic mini-screws in the patient's palate, varying in diameter from 2 to 2.3 mm and in length from 11 to 15 mm. After mini-screw insertion, another intraoral scan was taken for the fabrication of the appliance. Approximately three weeks later, the expander was placed in the patient's palate, and maxillary expansion was initiated immediately afterward according to the chosen protocol.
