Vector control of malpositioned segment during alveolar distraction osteogenesis by using rubber traction

Area of Science:

• Oral and Maxillofacial Surgery
• Orthodontics
• Regenerative Medicine

Background:

• Alveolar distraction osteogenesis is a common procedure for bone segment repositioning.
• Segmental malposition can occur as a complication following distraction osteogenesis.
• Maintaining the vector of the repositioned segment is crucial for successful outcomes.

Observation:

• A patient developed a malpositioned segment at the end of alveolar distraction osteogenesis.
• The complication involved a lingually or palatally inclined bone segment.
• Conventional fixation methods may not always suffice for complex malpositions.

Findings:

• A modified fixation technique using a wire splint was employed.
• The wire splint served as an anchorage to guide the malpositioned segment.
• Successful consolidation and ideal segment positioning were achieved post-treatment.

Implications:

• This approach offers a viable solution for managing malpositioned segments after distraction.
• The technique can help achieve optimal arch form and facilitate subsequent implant placement.
• It provides a valuable alternative for complex cases requiring precise bone segment control.
