دراسة ارتباطية لتحديد دور الاسنان في نمو القواعد الفكية بالاتجاه الامامي الخلفي

This study aims to examine the role that teeth buds play in identifying the active length of maxillary and mandibular bone. we conclude that: 1- there is no correlation between tooth sizes and sagittal positions of jaws. 2- teeth buds do not play a significant role as growth centers. 3- teeth comply with jaw growth, but do not specify it, and that the tooth role is determined by three mechanisms: compensation, adaptation, and causing some coercive malocclusions . 4- in case of early diagnosis of defects in the growth of jaw bases, premature extraction of tooth buds does not play such a role in restricting this growth.
