Interdisciplinary Treatment of a Severely Displaced Mandibular Canine: A Long-Term Follow-Up
Volume 46 : Number 11 : Page 687 : Nov 2012
Impacted canines are less prevalent in the mandible than in the maxilla,1,2 and impacted mandibular canines that have migrated to the opposite side of the midline (transmigration) are even more rare.3...

Surgical Luxation and Orthodontic Traction of an Ankylosed Upper First Molar
Volume 50 : Number 5 : Page 0 : May 2016
Dental ankylosis is a cellular change in the periodontal ligament that results in continuity or fusion between the alveolar bone and cementum, making it impossible for a tooth to erupt completely. It is identified clinically by the failure of a tooth to erupt through the oral epithelium, by incomplete eruption, or by a lack of vertical movement compared with the adjacent teeth and the alveolar bone. Although ankylosis is more common in the primary dentition, it may also affect the permanent teeth, typically the molars. Bone defects are often associated, especially when ankylosis occurs during active vertical growth of the maxilla.

An Effective Approach to Correcting Anterior Crossbite in a Class III Patient
Volume 54 : Number 11 : Page 705 : Nov 2020
When early treatment is impossible, permanent teeth can be moved to compensate for a skeletal Class III discrepancy and anterior crossbite. The authors demonstrate the use of a 2 × 4 appliance and acrylic biteplane to correct a late-diagnosed skeletal Class III malocclusion.

Treatment of Mandibular Alveolar Prognathism by a Lower Anterior Subapical Osteotomy
Volume 32 : Number 12 : Page 747 : Dec 1998
Mandibular alveolar prognathism is often treated by orthodontic treatment without accompanying surgery, in cases where the malocclusion and protrusive profile are not severe enough to warrant sagittal...

CASE REPORT
Volume 54 : Number 8 : Page 473 : Aug 2020
This adult patient presented with a recurring cyst that had resulted in a severe asymmetrical occlusal deformity. Treatment involving rapid maxillary expansion, followed by asymmetrical orthodontic mechanics with intermaxillary elastics, achieves a functional occlusion and esthetic result.

Targeted Mechanics for Limited Posterior Treatment with Mini-Implant Anchorage
Volume 49 : Number 12 : Page 777 : Dec 2015
The introduction of temporary anchorage devices (TADs) has facilitated orthodontic management of complex dentofacial problems. TADs have also elicited the creativity of orthodontists in designing new appliances and approaches for treating different malocclusions. One such approach involves delivering orthodontic forces directly from mini-implants in the buccal segments without bonding the posterior teeth. Introduced by Chung and colleagues, this "biocreative therapy" obtains skeletal anchorage from sandblasted and acid-etched miniscrews, called C-implants, which are placed interdentally between the first molars and second premolars. The archwire is inserted in the anterior brackets and secured posteriorly in the slots of the C-implants to retract the anterior teeth during space closure. Because the implants are partially osseointegrated, they can resist these torsional forces without failing. Chung and colleagues have indicated that biocreative therapy was especially appropriate for cases of bimaxillary dentoalveolar protrusion and Class II cases with good buccal occlusion. Advantages of their method include three-dimensional control of the active units, a minimal need for patient compliance, and significantly reduced risks of root resorption or white-spot lesions in the posterior segments.

Skeletal Open-Bite Correction with Mini-Implant Anchorage and Minimally Invasive Surgery
Volume 52 : Number 9 : Page 485 : Sep 2018
In this adult patient with skeletal open bite and excessive lower facial height, orthognathic surgery is avoided by a combination of miniscrew-anchored maxillary posterior intrusion and minor esthetic procedures, including a reduction genioplasty and submental liposuction.
