Corticotomy-assisted maxillary protraction with skeletal anchorage and Class III elastics

Treatment Options for Class III Malocclusion in Growing Patients with Emphasis on Maxillary Protraction

“…Several appliances are used for early treatment of skeletal Class III, including Bionator [ 15 ], Frankel (FR-III) [ 17 ], chin cup [ 21 ], double-plate appliance [ 19 ], Eschler appliance “progenic appliance” [ 18 ], and protraction face mask. Orthopedic protraction of the maxilla is a popular treatment modality, with some limitations, including problems with patient compliance, limited protraction of the maxilla (2-3 mm in 9–12 months), unwanted dentoalveolar effects, and the possibility of relapse as a result of late mandibular growth [ 28 , 29 , 56 ].…”

“…Some of the complications associated with dental anchorage are resolved by skeletal anchorage. Recently, osseointegrated implants, titanium screws, onplants, and miniplates have been used as stable anchorage for maxillary protraction [ 41 , 46 , 56 , 70 ].…”

“…The proclination of mandibular incisors might be explained by the new posture of the tongue that acts on these incisors after correction of anterior crossbite [ 56 , 73 ].…”

“…A 3.82 mm forward movement of the nose tip was reported as a result of the BAMP protocol [ 77 ]. The upper lip and lip sulcus also moved forward, and the soft tissue B point and pogonion moved backward during the protraction period, indicating improvements in the soft tissue profile in line with the underlying skeletal components during the protraction procedure [ 56 , 78 , 79 ].…”

Comparison of short-term effects between face mask and skeletal anchorage therapy with intermaxillary elastics in patients with maxillary retrognathia

“…This is also the case with Wits appraisal, which can be affected by the cant of occlusal plane and by its variations due to tooth eruption (21). In this study, ANB° and Wits appraisal were used as one of the inclusion criteria to diagnose skeletal Class III malocclusion since these are commonly used parameters for cephalometric evaluation of Class III malocclusion (16,21,24).…”
