Class II Correction in an Adult High-Angle Patient Using Low-Friction Mechanics and Skeletal Anchorage

Volume 51 : Number 7 : Page 419 : Jul 2017

A nonextraction approach is demonstrated in an adult high-angle patient with a skeletal Class malocclusion and severe crowding. By using low-friction, passive self-ligating brackets and bilateral temporary anchorage devices over 18 months of treatment, the authors are able to avoid any surgical intervention other than an advancement genioplasty.

Anterior Open-Bite Correction with Miniscrew Anchorage and a Combination of Upper Lingual and Lower Labial Appliances

Volume 51 : Number 11 : Page 719 : Nov 2017

This report illustrates how anterior open bite can be corrected in a Class II case by combining upper lingual and lower labial brackets with miniscrew anchorage to achieve intrusion of the maxillary posterior teeth and consequent counterclockwise mandibular rotation.

Volume 57 : Number 4 : Page 237 : Apr 2023

Dr. Venugopal and colleagues highlight orthodontic mechanics for simultaneous incisor retraction and intrusion in a high-angle patient with a protrusive profile. Skeletal anchorage is employed for vertical control during retraction of both arches, followed by placement of a maxillary intrusion arch.



Management of a Calcifying Odontogenic Cyst with an Odontoma During Treatment of a Class II, Division 1 Malocclusion

Volume 56 : Number 7 : Page 20220701 : Jul 2022

This report shows a nongrowing patient with a full-step Class II molar relationship in whom extraction of the upper first premolars was followed by camouflage therapy using temporary anchorage devices. Development of a calcifying odontogenic cyst with an odontoma further complicated treatment.



Class II Correction with Carriere Motion 3D Appliance and Clear Aligner Therapy

Volume 56 : Number 3 : Page 187 : Mar 2022

The Carriere Motion 3D can be used to establish a Class I dental relationship before proceeding with full orthodontic treatment. This Class II case was completed with only four months of the Carriere Motion and intermaxillary elastics, followed by eight months of clear aligners.



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...



Orthodontic Management of Asymmetry after Surgical Removal of a Keratocystic Odontogenic Tumor of the Mandible

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.
