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.

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.

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...

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.

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.

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.

In cleft patients, a maxillary transverse deficiency is often more pronounced in the anterior region. A report of a skeletal Class III case shows how a banded fan-type palatal expander can promote differential expansion and avoid unwanted posterior side effects.
