Mid-facial skeletal and soft tissue changes after maxillary skeletal expander application: a retrospective CBCT study.

ABSTRACT:

Background

The increased resistance of midpalatal, zygomaticomaxillary, and pterygopalatine sutures over time reduces the dentofacial orthopedic effect of conventional expanders. To address this, mini-screw-assisted rapid palatal expanders have been developed. The aim of this study was to investigate the mid-facial soft tissue changes along with rotational movements of zygomaticomaxillary complex after maxillary skeletal expander 2 (MSE 2) application.

Methods

Pre- and post-expansion CBCT images of 17 patients (10 female, 7 male) with transversal maxillary deficiency and treated with MSE 2, were enrolled in this retrospective study. Eight skeletal angular measurements were performed in the coronal and axial zygomatic sections. Besides, nineteen linear and three angular soft
