Cephalometric roentgenography in nonhuman primates requires more precise head positioning than that afforded by commonly used ear rod techniques. A standard cephalometric headholder was therefore modified and a technique was developed to implant an attachment that would permit precise positioning of the head in all three planes of space. This method has been used in 36 animals, and at 35 months postsurgery the implants have remained stable and tissue compatibility is generally excellent. Roentgenograms obtained with this technique offer a high degree of accuracy in documenting growth changes and responses to orthodontic treatment.
