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 permit precise positioning of the head in all three planes of spce. This method has been used in 36 animals, and at 35 months postsurgery the implants have remained stable and tissue compatiblity is generally excellent. Roentgenograms obtained with this technique offer a high degree of accuracy in documenting growth changes and response to orthodontic treatment.
在非人灵长类动物中进行头影测量X线摄影，需要比常用的耳杆技术更精确的头部定位。因此，对标准的头影测量头托进行了改进，并开发了一种技术来植入一个附件，该附件能够在空间的三个平面上对头进行精确定位。该方法已应用于36只动物，术后35个月植入物保持稳定，组织相容性总体良好。用该技术获得的X线片在记录生长变化和正畸治疗反应方面具有高度的准确性。
