Esthetic Provisional Restoration after Space Closure in Patients with Missing Upper Lateral Incisors
Volume 50 : Number 6 : Page 0 : Jun 2016
Orthodontic space closure in a patient with a missing upper lateral incisor requires a mesial shift that will bring the canine and first premolar into esthetic focus. Additive or subtractive restorative measures such as odontoplasty or enamel reduction will then be needed to alter the visible tooth surfaces. Many cases require individualized adaptation of tooth shapes and colors.

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.

Use of Osseointegrated Implants for Orthodontic Anchorage
Volume 51 : Number 7 : Page 406 : Jul 2017
This biomechanical setup, called the handlebar-style technique, uses an osseointegrated implant-supported device as anchorage to accommodate vectors for correction of a single misaligned tooth while preventing undesirable movement of adjacent teeth. An existing implant can be used or one can be strategically placed, as illustrated in two cases.
