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

Efficacy of Mini-Implant-Assisted Maxillary Expansion on Late Adolescents and Adults and Its Effects on Nasal Permeability and Airway Volume Using Three Different Activation Protocols: A Randomized Controlled Trial (MARPE_1)

Sponsor

Erasme University Hospital

Enrollment

60 participants

Start Date

Oct 2, 2024

Study Type

INTERVENTIONAL

Conditions

Narrow Maxilla

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.

Eligibility

Min Age: 16 Years

Inclusion Criteria2

from the age of 16 onwards
who presented with transverse maxillary discrepancy (unilateral, bilateral, anticipated, or constriction without crossbite).

Exclusion Criteria4

history or presence of maxillofacial surgery, cleft lip and palate, craniofacial anomalies or syndromes, congenital tooth anomalies, and periodontal disease.
Patients who had previously palatal expansion were excluded also.
Presence of anatomic or pathological obstacle of the palatal mini-screw insertion (impacted tooth, tumor.)
refusal of study participation

Interventions

DEVICEMini-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.
