Positional changes of the lips concomitant to incisor retraction: an important issue in orthodontics

Abstract:
Lip response to incisor retraction following extraction therapy is continuously investigated. The following is a summary of available evidence in this regard. The reaction of the lips to incisor retraction cannot be predicted with certainty. This is due to many variables such as gender, growth, morphology, and function. Also, for some patients, it is difficult to completely relax their lips during cephalogram taking. All these variables interact in studies on this topic.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
