“…All linear maxillary measurements increased after RME. Similar results were reported by Kartalian et al 14 In the current study, after 6 months of retention the actual increase in the linear maxillary measurements were found to be lower than those observed immediately after RME. This may be attributed to the rebound phenomenon occurring on the maxillary halves.…”

“…The angle between the long axis of the teeth and the reference plane was measured for the left and right sides and recorded as the long axis angle for each tooth. The linear and angular measurements for the maxilla and maxillary teeth were performed using the method described by Kartalian et al 14 For the maxilla, 18 linear and 6 angular measurements were performed ( Fig 2). The nasal floor was measured tangent to the nasal floor at its most superior level and parallel to the lower border of the hard palate.…”

Objective: This study aimed at evaluating the changes in mandibular arch widths and buccolingual inclinations of mandibular posterior teeth after rapid maxillary expansion (RME). Methods: Baseline and post-expansion cone-beam computed tomographic (CBCT) images of patients who initially had bilateral posterior cross-bite and underwent RME with a banded-type expander were assessed in this study. The patients included 9 boys (mean age: 13.97 ± 1.17 years) and 11 girls (mean age: 13.53 ± 2.12 years). Images obtained 6 months after retention were available for 10 of these patients. Eighteen angular and 43 linear measurements were performed for the maxilla and mandible. The measurements were performed on frontally clipped images at the following time points; before expansion (T1), after expansion (T2), and after retention (T3). Statistical significance was assessed with paired sample t-test at p ＜ 0.05. Results: T1-T2 comparisons showed statistically significant post-RME increases for all measurements; similarly, T2-T1 and T3-T1 comparisons showed statistically significant changes. The maxillary linear and angular measurements showed decreases after expansion, and mandibular linear and angular measurements increased after retention. Conclusion: All mandibular arch widths increased and mandibular posterior teeth were uprighted after RME procedure.

“…7,8 RME has also been reported to cause the loss of quality and amount of alveolar bone. 9,10 Although the effects of RME on alveolar bone thickness and alveolar bone height have been investigated in previous studies using 3-D with cone-beam computed tomography (CBCT), [9][10][11] to our knowledge no study evaluating the effects of asymmetric rapid maxillary expansion (ARME) on alveolar bone in 3-D has been published. Therefore, the aim of this study was to evaluate the effects of ARME on alveolar bone thickness, buccal alveolar bone height (BABH), and the incidence of dehiscence and fenestration.…”

Objective: To quantitatively evaluate the effects of asymmetric rapid maxillary expansion (ARME) on cortical bone thickness and buccal alveolar bone height (BABH), and to determine the formation of dehiscence and fenestration in the alveolar bone surrounding the posterior teeth, using conebeam computed tomography (CBCT). Materials and Methods: The CBCT records of 23 patients with true unilateral posterior skeletal crossbite (10 boys, 14.06 6 1.08 years old, and 13 girls, 13.64 6 1.32 years old) who had undergone ARME were selected from our clinic archives. The bonded acrylic ARME appliance, including an occlusal stopper, was used on all patients. CBCT records had been taken before ARME (T1) and after the 3-month retention period (T2). Axial slices of the CBCT images at 3 vertical levels were used to evaluate the buccal and palatal aspects of the canines, first and second premolars, and first molars. Paired samples and independent sample t-tests were used for statistical comparison. Results:The results suggest that buccal cortical bone thickness of the affected side was significantly more affected by the expansion than was the unaffected side (P , .05). ARME significantly reduced the BABH of the canines (P , .01) and the first and second premolars (P , .05) on the affected side. ARME also increased the incidence of dehiscence and fenestration on the affected side. Conclusions: ARME may quantitatively decrease buccal cortical bone thickness and height on the affected side.

“…19,20,33 However, there have been only a few studies that have focused on the effects of RME on craniofacial sutures by evaluating the frontal (coronal) dimension. [34][35][36][37] Overall, the present literature review suggests the bonded appliance is the optimal appliance before the maxillary first premolars (Mx4s) erupt, and the banded expander is more desirable thereafter. The aim of this study is to quantitatively evaluate the efficiency of a standardized activation (5 mm) in a consecutive series of children (6-15 years) treated with a developmentappropriate appliance.…”

Objective: To assess the three-dimensional (3D) skeletal response to a standardized 5 mm of rapid maxillary expansion (RME) in growing children (6-15 years) with maxillary width deficiency and crowding. Materials and Methods: A bonded appliance was used prior to the eruption of the maxillary first premolars (Mx4s), and a banded appliance was used thereafter. A consecutive sample of 89 patients (29 boys and 60 girls) from a large pediatric dentistry and orthodontics practice was divided into four groups: 1) 6-8 years old (n 5 26), 2) 9-11 years old with unerupted Mx4s (n 5 21), 3) 9-11 years with erupted Mx4s (n 5 23), and 4) 12-15 years (n 5 19). For all patients, the 3D evaluation of dental and skeletal effects was performed with cone-beam computed tomography (CBCT). Results: For both appliances in all patients, CBCT confirmed a triangular pattern of expansion in both the frontal and sagittal planes. Overall, both appliances produced significant maxillary expansion (.80% of the 5-mm activation), but older children showed a progressively more dental (less skeletal) response. Comparison of the two types of expanders in the crossover sample, children aged 9-11 years, showed that the bonded RME produced the most efficient skeletal expansion in the preadolescent sample. Increased maxillary width at the level of the zygomaticomaxillary suture was the best indicator for development of maxillary arch circumference. Conclusion: Development-dependent appliances (bonded RPE before Mx4s erupt, and a banded device thereafter) provided optimal RME treatment for all children from age 6-15 years.
