Objective To investigate the effect of tooth agenesis on craniofacial structure development. Method The caphalometric analysis was performed in 196 patients with tooth agenesis treated in our department. Results In the patients with mild tooth agenesis, the limited changes in hard and soft tissue parameters were induced only by the number of tooth absence. But in the patients with severe tooth agenesis, the agenesis of mandible and maxillary bone developed,and the protrusion of the relative soft tissue decreased. Conclusion Severe tooth agenesis will affect the development of mandible and maxillary bones.
