The occipital pull chin cup is frequently used to treat:
Correct Answer: Mild to moderate mandibular prognathism
Description: Types of Chin Cup
Occipital pull chin cup derives anchorage from the occiput region. This is used in Class III cases with mild to moderate mandibular prognathism, who can bring their incisors in an edge-to-edge position at centric relation. Patients with short anterior facial height also benefit from this type of chin cup. This is the more commonly used chin cup.
Vertical pull chin cup derives anchorage from the parietal region. It is indicated in high angle cases or long face patients, as it helps to close the angle of the mandible and increase the posterior facial height.
