“…[13][14][15] Recently, the use of the modified C-palatal plate (MCPP) for maxillary arch distalization was reported for Class II corrections in both adolescents and adults. 1,[16][17][18][19][20][21] The MCPP is a distalization appliance with a large range of action that can be easily placed without raising a flap. It also has been shown to have the capability of vertical control during distalization.…”

“…A case using mini-screws and modified palatal anchorage plates to treat an adolescent skeletal Class II patient with an anterior open bite was reported. 17 In addition, other studies have demonstrated the usefulness of skeletal anchorage in improving bialveolar protrusion, or alternatively for protraction of maxillary teeth. 18 19 Movement patterns for mandibular versus maxillary teeth are different due to the anatomic nature of mandibular bone.…”

ObjectiveThe objective of this study was to analyze the patterns of tooth movements when distalization of mandibular molars using a mini-plate took place. A finite element analysis was applied to analyze patterns of tooth movements.MethodsThe model of the mandible and teeth were used to build a finite element analysis model, and a mini-plate was inserted in the mandibular ramus. Two different orthodontic forces were established for displacement of mandibular molars. Orthodontic forces were applied at the level of the bracket and at the level of the cemento-enamel junction in the mandibular canine respectively.Resultsorthodontic forces at the level of the cemento-enamel junction resulted in a greater biomechanical bodily movement in distalization of the mandibular molars compared to when the orthodontic forces were applied at the level of the bracket. Applying orthodontic forces to the cemento-enamel junction also resulted in unwanted greater extrusive movements in distalization of the mandibular molars compared to the bracket level.ConclusionsWith considering the mode of orthodontic teeth movement, applying different vertical orthodontic forces for distalization of mandibular molars can lead to more effective distalization of teeth.

“… 7 8 9 10 The modified C-palatal plate (MCPP) has been reported to result in successful distalization of the maxillary dentition without significant side effects in adolescents. 11 12 In addition, it was recently reported that MCPPs and headgear resulted in similar sagittal skeletal and dental treatment effects in growing patients. 13 Moreover, one study demonstrated that MCPPs can be used for maxillary distalization in adults 14 ; however, it was a single-arm study and did not compare the treatment effects of MCPP with those of other conventional devices.…”

ObjectiveThe purpose of this study was to evaluate the dental and skeletal effects of the modified C-palatal plate (MCPP) for total arch distalization in adult patients with Class II malocclusion and compare the findings with those of cervical pull headgear.MethodsThe study sample consisted of the lateral cephalograms of 44 adult patients with Class II Division 1 malocclusion, including 22 who received treatment with MCPP (age, 24.7 ± 7.7 years) and 22 who received treatment with cervical pull headgear (age, 23.0 ± 7.7 years). Pre- (T1) and post-treatment (T2) cephalograms were analyzed for 24 linear and angular measurements. Multivariate analysis of variance was performed to evaluate the changes after treatment in each group and differences in treatment effects between the two groups.ResultsThe mean amount of distalization at the crown and root levels of the maxillary first molar and the amount of distal tipping was 4.2 mm, 3.5 mm, and 3.9° in the MCPP group, and 2.3 mm, 0.6 mm, and 8.6° in the headgear group, respectively. In addition, intrusion by 2.5 mm was observed in the MCPP group. In both groups, the distal movement of the upper lip and the increase in the nasolabial angle were statistically significant (p < 0.001). However, none of the skeletal and soft tissue variables exhibited significant differences between the two groups.ConclusionsThe results of this study suggest that MCPP is an effective treatment modality for total arch distalization in adults.
