“…3,4 However, these appliances depend on patient compliance and easily result in anchorage loss, which limits their clinical application. 5,6 In recent years, the use of microimplants in orthodontic practice enables better treatment outcomes in molar distalization. 6,7 The success of molar distalization depends on having enough available posterior space.…”

Objectives To analyze the mandibular retromolar space among normal-divergent adult patients with different sagittal skeletal patterns by cone-beam computed tomography (CBCT). Materials and Methods CBCTs of a total of 120 normal-divergent adult patients were investigated. Patients were categorized into the following three groups according to their ANB angle: skeletal Class I (48 patients), skeletal Class II (36 patients), and skeletal Class III (36 patients). Four different planes parallel to the mandibular occlusal plane were used to measure the retromolar space. The retromolar space was measured by two reference lines and then compared between different sagittal skeletal patterns groups. The incidence of root contact with the inner lingual cortex was compared among the three groups. Results The retromolar space of the Class III patients was significantly larger than that of Class I patients and Class II patients. Compared with Class I and Class III patients, Class II patients had a smaller retromolar space and higher incidence of contact with the inner cortex of the mandible. Conclusions Class III patients had a larger retromolar space than Class I patients and Class II patients in four different planes. The mandibular retromolar space should be evaluated by CBCT in patients who need mandibular molar distalization.

“…During retraction of the maxillary arch with TSADs, one of the consistent side effects is reported to be intrusion of the molars with a slight clockwise rotation of the occlusal plane. Most studies showed that the amount of the maxillary first molar intrusion was close to 1 mm or less, except for one case in which 2.9 mm was reported 20 . This phenomenon is related to the fact that the retraction force vector is applied below the center of resistance in the maxilla.…”

Conversely, the protraction force vector from the palatal TSADs may cause unwanted extrusion of the molars with a counterclockwise rotation of the occlusal plane.…”

This case report describes the interdisciplinary treatment of a 23‐year‐old female with Class III malocclusion and a missing maxillary left second premolar. Treatment alternatives were discussed, and the selected treatment plan was presented to illustrate a way to gain space for the premolar implant restoration and correct Class III relationship through maxillary molar retraction followed by maxillary total arch protraction with a palatal temporary skeletal anchorage device. Esthetic anterior alignment and functional occlusal rehabilitation was achieved, and facial balance was maintained at the end of treatment. Clinical Significance Implant restoration in conjunction with regaining orthodontic space by a team of multidisciplinary dental specialists presents an effective treatment solution to permanent tooth agenesis. Class III malocclusion can be treated with a combination of maxillary protraction and mandibular retraction using temporary skeletal anchorage devices. The versatility of modified palatal C‐plates presents greater clinical application when related side effects are controlled with solid understanding of their biomechanics.

“…3,4 With the introduction of the temporary skeletal anchorage devices (TSADs), buccal miniscrews have been used to correct Class II malocclusion by distalizing maxillary molars. [5][6][7] When a large amount of total arch distalization is needed, interdental miniscrews need to be relocated because of the limited inter-radicular distance. 8 To overcome this drawback, palatal placement of TSADs has been proposed by some clinicians due to the broader range of tooth movement possible and less tipping of the first molars.…”

Introduction This study aimed to compare the skeletodental and soft tissue changes with total arch distalization using a modified C‐palatal plate (MCPP) and maxillary first premolar extraction treatment in Class II malocclusion patients with severe overjet. Setting and sample population The sample consisted of 46 adult patients who had Class II Division 1 malocclusion with severe overjet; 25 of them received non‐extraction treatment with MCPPs (age, 22.5 ± 7.2 years), and 21 received maxillary first premolar extraction treatment (age 23.4 ± 6.5 years). Method A total of 26 variables were measured on pre‐ and post‐treatment lateral cephalograms. To evaluate the differences between pretreatment and post‐treatment in each group, t tests and Wilcoxon rank‐sum tests were used. To compare the amount of change between the two groups, MANOVA test was used. Results The overjet was significantly reduced in the MCPP and extraction groups by 4.8 mm and 5.4 mm, respectively. However, the two groups had no significant difference in the sagittal, vertical and angular changes of the maxillary incisors. In addition, regarding soft tissue changes, the MCPP and extraction groups showed an increased nasolabial angle of 7.5° and 9.4°, decreased upper lip to the true vertical line of 1.8 mm and 2.2 mm, respectively (P < .001). Conclusions There was no significant difference in the skeletal changes between the MCPP and extraction groups, and the reduction in overjet was similar in the groups. These results suggest that MCPP might be a viable treatment option for total arch distalization in Class II malocclusion patients with severe overjet.
