About

This study compares the effect of MARPE (mini-implant assisted rapid palatal expansion) versus MARPE+ MOP (Micro-osteo-perforation) on nasal airway and maxillary transverse deficiency in non-growing patients.

Full description

All participants with skeletal transverse deficiency with unilateral or bilateral cross-bite aging 20-25 years were treated by expansion of maxillary arch as a first phase of treatment with one expander screw which was anchored to mini-implants placed in the palatal region (Mini-implant assissted rapid palatal expansion; MARPE). The patient's bone support in the anterior area of the palate was examined on CBCT. Micro-osteoperforation (MOP) was done along of medial palatine raphe in the intervention group. Control-group is the same of the intervention group but without micro-osteo-perforations.

Enrollment: 24 patients
