Abstract:
Objective To study the parent-offspring similarity of class Ⅱ division 1 malocclusion. Methods On the basis of family units, the polygonic curves and superimposed graphs of parents with those of the offspring were compared. Results (1) Craniofacial structure of most parents of the class Ⅱ division 1 patients have class Ⅱ convex tendency. (2) The curves of the offspring resemble one or two of the parent′s in 84% of the families, and the resemblance mainly concentrates in skeleton. Conclusions (1) Class Ⅱ division 1 malocclusion is characterized by familial aggregativity. (2) High probability of heredity exists in parent-offspring similarity, and we believe that hereditary factors dominate in skeletal area while in dental area there is a higher probability that environmental factors dominate.
