“…First, the method of measuring the borders of separated midpalatal suture was highly time‐dependent and skill‐sensitive . The borders of the midpalatal suture and midsagittal bony landmarks become difficult to be clearly defined over time after expansion due to the immediate surface remodeling and consequent CBCT image blurring . Second, the midpalatal suture was not always fully separated from the ANS to the PNS, in consistence with previous systematic review reporting 14.2% partial separation from the ANS to the transverse palatal suture .…”

Objectives To evaluate three‐dimensional (3D) craniofacial changes induced by a non‐surgical tooth‐bone‐borne rapid palatal expander (TBB‐RPE) according to the symmetrical pattern of expansion, to investigate the 3D changes between the sides in patients with asymmetric expansion, and to identify the related factors of asymmetric expansion. Setting and sample population Sixty‐six patients (mean age: 19.3 ± 5.7 years) treated with TBB‐RPE were divided into a symmetric expansion group (Group S, n = 46) or asymmetric expansion group (Group A, n = 20). Group S was subdivided into Group Ss (n = 27), with bilateral frontomaxillary suture (FMS) split, and Group Sn (n = 19), with no FMS split. Materials and methods Pre‐ and post‐expansion cone‐beam computed tomography images were superimposed, and the common coordinated system was set. All landmarks were designated as coordinate pairs, and treatment changes were automatically calculated. Analysis of variance was conducted for intergroup comparison of craniofacial changes, and logistic regression analysis was performed to identify the related factors of asymmetric expansion. Results The frequency of asymmetric expansion was 30.3%. Group A with unilateral FMS split showed less craniofacial changes than Group Ss and more changes than Group Sn. Group A exhibited different nasomaxillary displacement between the two halves, showing greater changes in the FMS‐split side. Among the tested six variables (age, gender, Angle's classification, unilateral crossbite, maxillary cant and chin deviation), chin deviation was uniquely associated with asymmetric expansion. Conclusions Tooth‐bone‐borne rapid palatal expander had a risk of asymmetric expansion, especially in facial asymmetric patients with chin deviation, producing different craniofacial changes from symmetric expansion.

“…Facial changes following SARME re ect the underlying dento-skeletal movements. The most frequently reported ndings are widening of the nose and an increased projection of the cheek area in the lateral direction (9). A slight retro-positioning of the upper lip (10) and an anterio-inferior displacement of the whole naso-maxillary complex after SARME were also reported (11).…”

“…3D imaging modalities, such as cone-beam computed tomography or stereometric surface imaging, are rapidly replacing conventional 2D technologies (9). The most obvious effects of SARME are widening of the maxillary dental arch and expansion of the maxillary and palatal structures in the transverse plane (9). Facial changes following SARME re ect the underlying dento-skeletal movements.…”

Background: The purpose of the study was to evaluate the three-dimensional (3D) facial changes following surgically assisted rapid maxillary expansion (SARME). In 15 skeletally mature patients with maxillary transverse deficiency the planned maxillary expansion (on average 8.8 mm ± 2.3 mm) was achieved with bone-borne palatal distractor. The 3D optical scans of the facial surface were obtained before and 6 months after SARME and compared with cephalometric and regional analysis to evaluate the soft-tissue changes. Findings. The largest differences between the pre- and post-operation scans were observed for the paranasal and cheek area (1.4 ± 1.0 mm) in the lateral direction with a soft-to-hard tissue ratio of 0.22. Significant differences occurred for an increased nasal width, a decreased upper-face height with an unchanged lower height, an increased vertical philtrum height and an increased nasolabial angle. A significant increase in the facial profile angle was also observed, resulting in an increased facial convexity and anterior displacement of the upper-lip area. Conclusions. We have confirmed the widening of the nose and increased projection in the cheek and paranasal area in the lateral direction after maxillary expansion, while we found facial convexity increases, reflecting the underlying advancement of the maxilla.

“…2 With the closure of the craniofacial sutures and an increase in density of the MPS, RME cannot be performed using the conventional method 3 and surgically assisted techniques are required to provide skeletal expansion. 4,5 In addition to being invasive and expensive, surgically assisted techniques are associated with surgical risks. 6,7 Various methods have been proposed to evaluate the stage of MPS maturation using 3-dimensional images to predict the need for surgical treatment to support RME.…”

OBJECTIVE: To evaluate the stages of midpalatal suture (MPS) maturation in patients older than 15 years, and to determine the correlation between the stage of MPS maturation and age and cervical vertebral maturation (CVM). MATERIALS AND METHOD: Cone-beam computed tomography (CBCT) scans of 50 patients (29 female and 21 male; mean age, 19.79 ± 4.09 years) were evaluated. Good quality CBCT images from 15-30-year-old patients for evaluation of impacted canines or determination of orthognathic surgery were selected. The CBCT images were evaluated at two different time intervals for determination of the stages of MPS and CVM. The stages of MPS maturation were classified as A, B, C, D, or E using the axial sections by using a method validated previously. The stages of CVM were classified using sagittal sections of the CBCT images. Intra-examiner agreement was assessed using the Kappa test. The correlations between MPS maturation and chronological age and CVM were assessed using Spearman's rank correlation analysis. RESULTS: The Kappa coefficients for intra-examiner agreement were 0.837 and 0.865 for classification of the stages of MPS maturation and CVM, respectively. No significant correlation was observed between chronological age and maturation of MPS (r = 0.212, p = 0.139) and between the stages of CVM and maturation of MPS (r = 0.030, p = 0.839). CONCLUSION: The limitation of our study was a small sample size, and, on the basis of our results, neither CVM nor chronological age could be used as a convenient tool to determine the stage of MPS maturation in 15-30-year-old patients.
