What is it about?

In the clinic, intermaxillary asymmetric force is frequently used. However, what can be caused to condyles due to the traction force is not so clear. Therefore we detected the expression of RANKL and OPG in the subchondral bone of the condyles, when the rats subjected to unilateral traction in the anterior-superior direction using an elastic force.

Why is it important?

Different values or traction force cause a variation of the RANKL/OPG ratio through the expression of RANKL protein, modulating the activities of bone remodeling in the subchondral bone of condyle. Therefore, we'd better make the traction methods more stable to keep the condyle healthy.
