Alveolar Distraction

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Orthodontics

Background:

• Alveolar distraction osteogenesis (ADO) is a long-standing technique for reconstructing the alveolar bone.
• It offers combined augmentation of bone and soft tissues, enhancing the alveolar platform for dental rehabilitation.
• ADO is particularly beneficial for large or complex alveolar clefts, reducing defect size and associated fistulas.

Observation:

• The primary complication observed in ADO is the displacement of the bone segment being transported.
• This displacement can compromise the intended augmentation and functional outcomes.
• Careful surgical planning and device construction are crucial for successful ADO.

Findings:

• ADO effectively augments both bone and soft tissue volume in atrophic alveolar ridges.
• The technique successfully reduces the size of alveolar clefts and associated fistulas.
• Case-specific distractors have been developed to manage segment displacement, a common ADO complication.

Implications:

• ADO provides a viable solution for complex alveolar reconstructions, improving candidacy for dental implants.
• The combined tissue augmentation enhances aesthetic and functional results in patients with significant bone loss.
• Managing displacement with tailored distractors increases the reliability and success rate of ADO procedures.
