Inter-maxillary Fixation / Traction


Inadequate root length and/or periodontal support for elastic traction.

Orthognathic cases treated without full labial fixed appliances.


Case Details:

Multiple upper/lower mini-implants were inserted intra-operatively for immediate bone-supported IMF (shown here using powerchain fixation).

Mini-implants may remain in situ post-operatively for settling traction.


Key Points:

Buccal mini-implants (1.5mm diameter, 6 or 9mm length) are inserted at interproximal sites according to required traction locations.

Upper labial frenectomy may be required.
