Influence of the palatal plane cant and skeletal patterns in the hard palate thickness?

Abstract

Rapid palatal expansion (RPE) with expanders such as the Hass and Hyrax devices is used for the treatment of patients with transverse maxillary deficiency. 1,2 The side effects caused by these devices become more common as skeletal expansion decreases and include bone dehiscence or fenestration, gingival recession, root resorption, buccal tipping of the posterior teeth and post-treatment relapse. 3,4 The MARPE (microimplant-assisted rapid palatal expansion) technique is a modification of the rapid palatal expansion method, whose main difference is the insertion of mini-implants adjacent to the midpalatal suture to ensure greater bone expansion and less tooth movement. 5 Studies have observed that an average of 10% of
