Efficacy of Transverse Maxillary Expansion With AMCOP Preformed Appliances

Italy30 participantsStarted 2025-03-15

Plain-language summary

The present study aimed to investigate the cross-sectional effect of Class I AMCOP devices in patients of all possible skeletal types from both vertical skeletal pattern (normodivergent, hyperdivergent, hypodivergent) and sagittal skeletal pattern (skeletal Class I, skeletal Class II, skeletal Class III). The criterion for choosing patients was determined by the protocol of using these devices, which is to always perform an AMCOP First Class phase with the aim of improving transverse coordination of the arches, Spee's Curve and Wilson's Curve.

Inclusion Criteria: * patients presenting maxillary transverse deficits (that includes: posterior crossbite monolateral or bilateral; end-to-end occlusal relationships; excessive linguoinclination of lower posterior teeth due to the contraction of maxillary arch; limited permutation space of permanent elements) * patients with all sagittal and vertical skeletal patterns Exclusion Criteria: * syndromic patterns, cleft lip or cleft palate, severe malformations of the maxillae, severe skeletal asymmetry * physical or psychological limitations * presence of metallic restorations * previous orthodontic treatments
