Anchorage In Orthodontics (Part 1) | Dr Manase

Watch the “Anchorage In Orthodontics-Part 1” lecture presented by Dr Manase (Masters in Dental Surgery).

Why is this an important dental study video?
Tooth movement during orthodontic therapy is brought about by forces generated by active components of an orthodontic appliance. The force used to move teeth is derived from certain anatomic areas, which act as anchors.
According to Newton’s third law of motion, for every action there is an equal and opposite reaction. In accordance with this law, the forces used to move teeth may induce an equal and opposite force on the anchorage units tending to cause their movement which is not desirable.
The resistance that the anchorage areas offer to these unwanted tooth movements is called anchorage.
This orthodontics lecture covers what is anchorage and the different sources of anchorage.

Hoping that this orthodontics complete denture lecture helps add some value
