Maxillary expansion in an animal model with light, continuous force [PDF]

, 2018
Objectives: Maxillary constriction is routinely addressed with rapid maxillary expansion (RME). However, the heavy forces delivered by most RME appliances to expand the palate may lead to deleterious effects on the teeth and supporting tissues.

Effects of rapid-slow maxillary expansion on the dentofacial structures

Australasian Orthodontic Journal, 2023
To date, no study has determined if rapid followed by slow maxillary expansion (also termed ‘semi-rapid’ expansion) has the same effects on the dentofacial skeleton as rapid maxillary expansion.

Management of Class III Malocclusion and Maxillary Transverse Deficiency with Microimplant-Assisted Rapid Palatal Expansion (MARPE): A Case Report

Medicina, 2022
Microimplant-assisted rapid palatal expansion (MARPE) has been demonstrated successfully in maxillary expansion in late adolescence and adulthood. The maxillary advancement accompanied by expansion is frequently anticipated, which is beneficial for the ...
