Abstract
Objectives: To compare, using surface-to-surface (StS) matching, any shape differences between
the crossbite and noncrossbite side of the glenoid fossa and articular eminence in adult patients
affected by posterior unilateral crossbite (PUXB) and compare them with unaffected controls.
Materials and Methods: 32 cone beam computed tomography (CBCT) scans of patients (mean
age: 23.72 6 3.74 years) undergoing surgical maxillary expansion were analyzed to obtain threedimensional models of the left and right glenoid fossae that were superimposed using stable
anatomical reference points and then compared using StS matching to evaluate the presence of
any shape differences. These findings were compared with those obtained from 16 CBCT scans of
unaffected controls (mean age: 23.72 6 3.73 years).
Results: A mean difference of .11% was found between the study group and controls when
comparing the matching percentages of the two sides of the glenoid fossa and articular eminence
at all three levels of tolerance selected for this study. These differences were found to be highly
statistically significant (P .0001).
Conclusions: According to the shape analysis findings, adult PUXB patients exhibit a higher
degree of glenoid fossa and articular eminence shape differences compared to unaffected controls.
