Association between the severity of hypodontia and the characteristics of craniofacial morphology in a Chinese population: A cross-sectional study.

Compared with controls, patients with hypodontia tend toward a Class III skeletal relationship, reduced lower anterior face height, flatter mandibular plane, and more retrusive lips. The number of congenitally missing teeth had a greater effect on certain characteristics of craniofacial morphology in males than in females.
