Rapid canine distalization through segmental alveolar distraction osteogenesis

Area of Science:

• Orthodontics
• Oral and Maxillofacial Surgery
• Periodontology

Background:

• Canine retraction is a common orthodontic procedure.
• Traditional methods can be time-consuming.
• Segmental alveolar distraction offers a potentially faster alternative.

Purpose of the Study:

• To evaluate rapid canine distalization using segmental alveolar distraction in first premolar extraction cases.
• To assess periodontal tissue changes, tooth displacement, pulpal vitality, and root resorption.
• To determine the efficacy and safety of this distraction method.

Main Methods:

• The study included eight patients (20 teeth) undergoing segmental alveolar distraction.
• Pre- and post-treatment records included dental casts and radiographs.
• Periodontal health and canine pulpal vitality were assessed using established indices and electrical tests.

Main Results:

• Distraction was completed in a mean of 14.65 days.
• Mean canine distal displacement was 5.35 mm with 1.2 mm of anchorage loss.
• Canines exhibited mean distal tipping of 9.1 degrees; first molars showed no significant axial inclination change.

Conclusions:

• Segmental distraction osteogenesis is an effective method for rapid canine distalization.
• The procedure appears safe with acceptable periodontal response and vitality.
• This technique holds potential for routine orthodontic application.
