Efficiency of Cone-Beam Computed Tomography-Based Personalized Microimplant-Assisted Rapid Palatal Expansion in Patients With Maxillary Transverse Deficiency and Thin Palatal Bone.

ABSTRACT:

Introduction and aims

Maxillary transverse deficiency (MTD) affects approximately 10% of adults, but conventional expansion treatments are often ineffective and risky in mature patients due to suture fusion. Although microimplant-assisted rapid palatal expansion (MARPE) improves outcomes, it relies on sufficient bone thickness, posing a challenge for individuals with thin palatal bone. This study evaluates a digitally personalized MARPE approach, guided by cone-beam computed tomography-based bone mapping, for adults with MTD and thin bone (<2.5 mm).

Methods

A retrospective analysis was conducted on 18 patients. Custom MARPE appliances were designed using computer-aided design/computer-aided manufacturing technology, with microimplants placed strategically using surgical guid
