Mechanism of action and morphologic changes in the alveolar bone in response to selective alveolar decortication-facilitated tooth movement.

Background And Purpose: The aim of this study was to test if corticotomy-induced osteoclastogenesis and bone remodeling underlie orthodontic tooth movement and how selective alveolar decortication enhances the rate of tooth movement.

Materials And Methods: A total of 114 Sprague-Dawley rats were included in 3 treatment groups: selective alveolar decortication alone (SADc); tooth movement alone (TM); and "combined" therapy (SADc + TM). Surgery was performed around the buccal and palatal aspects of the left maxillary first molar tooth and included 5 decortication dots on each side.

Modeling of trabecular bone and lamina dura following selective alveolar decortication in rats.

Background: Modifying the balance between resorption and apposition through selectively injuring the cortical plate of the alveolus has been an approach to speed tooth movement and is referred to as periodontally accelerated osteogenic orthodontics. The aim of this study was to investigate the alveolar response to corticotomy as a function of time and proximity to the surgical injury in a rat model.

Methods: Maxillary buccal and lingual cortical plates were injured in 36 healthy adult rats adjacent to the upper left first molars.

Guided bone regeneration to repair an osseous defect.

The ultimate goal of orthodontic therapy is to establish functional and esthetic dental relationships in a balanced facial pattern. In patients with compromised periodontal support, the use of multidisciplinary treatment plans is essential in attaining these goals. This case report includes a thorough documentation of the orthodontic and periodontal treatments to demonstrate the effectiveness of guided bone regenerative procedures combined with a bone allograft to aid in correcting a dental malocclusion.
