Craniofacial growth in juvenile Macaca mulatta: A cephalometric study This study was supported, in part, by United States Public Health Service grants DE-02272 and DE-43120.

This paper describes a study of normal craniofacial growth of the juvenile rhesus monkey ( Macaca mulatta ). Serial data of 13 young monkeys of specific dental age were studied for a five month period by cephalometric radiography and the metallic implant technique. Growth patterns were described and localized growth changes quantified to determine the range of variability. Variability was found within areas of specific bones, e.g., the gonial region of the mandible, and in the relative degree of change of interbony relationships, e.g., maxillo-mandibular. There was generally less variability for most measures in this study than usually found in man. Compensatory factors, such as the adaptability of the dentition and the selective apposition and resorption of osseous surfaces minimized the occlusion expression of this observed variation, for all animals maintained a constant Class I molar relationship during the period studied.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37521/1/1330360307_ftp.pd
