Implantation of cranial base metallic markers in nonhuman primates

Abstract

Cranial base metallic markers are useful in growth and developmental research on the nonhuman primate model. Metallic implants aid in superimposing serial cephalometric roentgenograms in the study of craniofacial changes. They also enable measurement of linear and angular changes in the cranial base. The design of a special implant gun is described in detail. A suggested technique for placement of tantalum markers in the cranial base of nonhuman primates is discussed.
