The miniscrew-assisted rapid palatal expander (MARPE) has extended not only skeletal effects with fewer dental changes and but also the age limit of nonsurgical maxillary expansion treatment. Amid its gaining popularity in clinical orthodontics, our current understanding of treatment effectiveness, efficiency, and stability needs to be reassessed. In this review article, the authors have attempted to evaluate MARPE from various aspects with a focus on recent studies.

Objectives: To evaluate the treatment effects of the modified miniscrew-assisted rapid palatal expander (MARPE) and rapid palatal expander (RPE) with distalizers in patients with Class II malocclusion and maxillary crowding.
Materials And Methods: The sample comprised 28 skeletal Class I adolescents with dental Class II malocclusion and maxillary crowding of >4 mm who received nonextraction treatment. Fourteen patients were treated with a modified MARPE with distalizer (MMD), while another 14 patients were treated with a modified RPE with distalizer (MRD).

Purpose: This study aimed to evaluate the dental and skeletal stability one year after Miniscrew-Assisted Rapid Palatal Expansion (MARPE) by using 3D image data.
Methods: Patients with transverse maxillary deficiency from the age of 16 onwards were enrolled consecutively in this prospective longitudinal cohort study. The MARPE appliance was digitally and individually designed and fabricated.

In this case report, a 19-year-old male patient with maxillary transverse deficiency, concave profile, and facial asymmetry is presented. In the case of transversal insufficiency, nonsurgical maxillary expansion was performed with the miniscrew-assisted rapid palatal expansion (MARPE) appliance to reduce the number of surgeries and provide both dentoalveolar and skeletal expansion. The periodontal soundness and short-term stability of the maxillary expansion were confirmed both clinically and radiologically.

Introduction: This study aimed to evaluate the short-term and long-term skeletal and dental asymmetry with miniscrew-assisted rapid palatal expansion (MARPE), rapid palatal expansion (RPE), and control group using cone-beam computed tomography (CBCT) analysis.
Methods: A total of 180 CBCT scans were analyzed for 60 patients divided into 3 groups: MARPE (mean age 13.7 ± 1.
