“…Otherwise, the apical region is located as far as the cervical region of the tooth; therefore, the apical region was associated with total transversal movement of the tooth. Brunetto et al 17 investigated changes in buccal alveolar bone after rapid and slow maxillary expansion, and found that both protocols caused vertical and horizontal bone loss and that BABH decreased during maxillary expansion. Baysal et al 11 found that banded RME caused decreases in the BABH on both sides.…”

“…CBCT technology has many advantages compared with tomography, especially conventional radiographic imaging. 17,24,25 Leung et al 26 showed that alveolar bone height and thickness can be measured quantitatively with great accuracy, with more than 0.870 correlations. Sun et al 23 observed that decreasing the voxel size from 0.40 mm to 0.25 mm could improve the accuracy of alveolar bone linear measurement from the CBCT images.…”

“…To obtain this unilateral expansion, several designs, modifications, and surgical procedures have been suggested. 4,16,17 In this study, the ARME appliance was designed to strengthen the anchorage of the unaffected side by including, with the aid of an occlusal locking mechanism, the mandibular posterior teeth.…”

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.

“…These findings could be attributed to the buccal tipping that was previously mentioned in the existent discussion. The crestal alveolar bone height was rarely evaluated in previous studies concerning open bite correction; however, it was evaluated and found to be decreased by 1.89±0.59mm after rapid maxillary expansion in a previous clinical trial study (40) .…”

Objective: This study was designed to evaluate the effect of corticotomy and miniplates' usage as skeletal anchorage for maxillary molars' intrusion during correction of skeletal anterior open bite (SAOB). Patients, materials and methods: A sample of 22 patients with an age range from 14 to 22 years, suffering from skeletal anterior open bite with increased posterior maxillary vertical height. The participants were randomly divided into two groups according to the corticotomy approach. Group I: both buccal and palatal corticotomies were performed. Group II: only buccal corticotomy was performed. Buccal miniplates and palatal mini-screws were used as skeletal anchorage for maxillary molars' intrusion assisted by corticotomy. The measurements, including maxillary dento-alveolar heights (mm), bucal crestal alveolar bone heights (mm), bucco-palatal angulations (B-P˚) and mesio-distal angulations (M-D˚) of right and left maxillary first permanent molars, 4.5 months after intrusion commencement. Results: The dento-alveolar height as well as the buccal crestal alveolar height decreased significantly after intrusion in both groups (p≤0.001 and p≤0.05, respectively), but without significant differences between them. Similarly, the M-D and B-P angulations increased significantly after intrusion in both groups (p≤0.01 and p≤0.001, respectively), with no significant differences between both groups. Conclusions: The current corticotomy approaches and temporary anchorage devices (TADs) were similarly effective for maxillary molar intrusion in cases of (SAOB), but complete correction of SAOB was not achieved. Both the posterior maxillary dento-alveolar and buccal crestal alveolar bone heights diminished similarly in both corticotomy methods. Neither mesio-distal nor bucco-palatal angulations of maxillary first permanent molar crown revealed major changes in matching both approaches of intrusion.

“…Tooth-anchored expanders have been conventionally used, but they have several disadvantages, such as limited skeletal expansion, undesirable buccal tipping of the teeth, and buccal bone dehiscence. [13][14][15][16] To avoid these adverse effects, skeletal anchorage for rapid maxillary expansion has been reported. [17][18][19] This report presents the case of a patient with skeletal Class III malocclusion, transverse discrepancy, and facial asymmetry.…”

This case report presents the successful use of palatal mini-implants for rapid maxillary expansion and mandibular distalization in a skeletal Class III malocclusion. The patient was a 13-year-old girl with the chief complaint of facial asymmetry and a protruded chin. Camouflage orthodontic treatment was chosen, acknowledging the possibility of need for orthognathic surgery after completion of her growth. A bone-borne rapid expander (BBRME) was used to correct the transverse discrepancy and was then used as indirect anchorage for distalization of the lower dentition with Class III elastics. As a result, a Class I occlusion with favorable inclination of the upper teeth was achieved without any adverse effects. The total treatment period was 25 months. Therefore, BBRME can be considered an alternative treatment in skeletal Class III malocclusion. (Angle Orthod. 2015;85:322-334.)
