distalization

Distalization refers to the movement of a tooth or a group of teeth away from the midline of the dental arch. In orthodontics, this is a common procedure used to correct various malocclusions, such as Class II division 1 malocclusion where the upper incisors protrude excessively. Distalization aims to create more space in the dental arch, improve the relationship between the upper and lower jaws, and enhance the overall facial profile.

This movement can be achieved through various appliances, including headgear, distalizers, and clear aligners. Headgear applies an external force to the upper molars, pulling them backward. Distalizers are intraoral devices that exert a controlled force to move the molars distally. Clear aligners, a series of custom-made trays, can also be programmed to achieve gradual distalization over time.

The decision to perform distalization depends on a thorough orthodontic assessment, including cephalometric analysis and study models. Factors such as the patient's age, facial growth potential, and the severity of the malocclusion are considered. While effective, distalization may require a significant treatment duration and patient compliance with appliance wear. Potential side effects can include temporary discomfort, root resorption, or unwanted tooth movement if not carefully managed. The ultimate goal is to achieve a stable and functional occlusion with improved aesthetics.
