Objective: This retrospective clinical study aimed to evaluate the maturation of intramaxillary and circummaxillary suture systems
and cervical vertebral maturation as predictors of the skeletal response achieved by rapid maxillary expansion (RME).
Methods: A Digital Imaging and Communication in Medicine dataset of 20 patients (mean age: 15.55 years) prior (T0) and after
(T1: 3.5Å}0.5 months) to RME were retrieved from the archive and analyzed. Bone density values of midpalatal suture (MPS),
zygomaticomaxillary suture (ZMS), zygomaticotemporal suture (ZTS), pterygopalatine suture (PPS), and transverse palatine suture
(TPS) were measured. The cervical vertebral maturational stages (CVS) were examined. The linear distances between the most lateral
points of the piriform apertures were measured as the anterior reference, and the medial margins of the greater palatine foramina on
the axial slice were chosen as the posterior reference. The difference at T1-T0 was calculated as the skeletal response to RME at anterior
and posterior skeletal references. Spearman’s rho rank and Kruskal-Wallis tests were used.
Results: Mean density values of ZMS, PPS, ZTS, TPS, MPS-Anterior, and MPS-Posterior were 922.81, 807.44, 753.83, 640.77, 661.13, and
604.59 HU, respectively. Mean linear changes in anterior and posterior skeletal expansion were 2.93Å}1.78 and 1.93Å}2.52 mm. There
was no significant relationship between maturation indicators and skeletal response. Significant relationships were found between
CVS and MPS density and CVS and circummaxillary suture average density (p≤0.05).
Conclusion: Sutural density showed significant variations among CVSs. Although there was no correlati
