Orthodontic therapy using aligners is a modern treatment option among adult patients. In order to have an optimal control of the orthodontic resuslts, there is a need for knowing the deformation values that can appear in each type of aligner, the optimal thickness values of the appliances and the needed number of aligners for each case. The deformation values for a 0.2 mm repositioned lower cen...

OBJECTIVE To evaluate the results of a finishing protocol implemented in patients treated in the Orthodontics graduate program at Universidad de Antioquia. Evaluation was carried out by means of the criteria set by the Objective Grading System (OGS) of the American Board of Orthodontics (ABO). METHODS Cast models and panoramic radiographs of 34 patients were evaluated. The intervention group ...

For patients whose orthodontic problems are so severe that neither growth modification nor camouflage offers a solution, surgery to realign the jaws or reposition dentoalveolar segments is the only possible treatment. Surgery is not a substitute for orthodontics in these patients. Instead, it must be properly coordinated with orthodontics and other dental treatments to achieve good overall resu...

This report describes the surgical and orthodontic management of a patient with a palatally impacted permanent maxillary canine. Following surgical exposure, orthodontic traction was applied to reposition the canine with resultant proper functioning, excellent esthetics, and good periodontal health.

Introduction: The causal relation between tongue thrust swallowing or habit and development of anterior open bite continues to be made in clinical orthodontics yet studies suggest a lack of evidence to support a cause and effect. Treatment continues to be directed towards closing the anterior open bite frequently with surgical intervention to reposition the maxilla and mandible. This case repor...

For patients whose orthodontic problems are so severe that neither growth modification nor camouflage offers a solution, surgery to realign the jaws or reposition dentoalveolar segments is the only possible treatment option left. One indication for surgery obviously is a malocclusion too severe for orthodontics alone. It is possible now to be at least semiquantitative about the limits of orthod...

A beautiful smile comprises a perfect balance of the white and pink. gummy has been prevalent esthetic disorder with varied etiologies including skeletal, dento-alveolar, or soft-tissue origin. It can be managed by variety treatment modalities after appropriate diagnosis planning. If it is due to jaw deformities, altered passive eruption tooth malpositioning, corrective measures incorporate ort...

In this article, we discuss the development of methods for computer-aided jaw surgery, which allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3-dimensional surface mo...

Techniques for the three-dimensional analysis of facial morphological changes resulting from surgical treatment have recently been proposed. These approaches largely rely on expert manual intervention for placing anatomical landmarks on 3-D facial models which is time consuming and error prone. A new automated approach is presented here which combines a stereo-assisted active shape model for 3-...
