Abstract

The purpose of this study was to investigate cranial and facial bone growth in the puberal Macaca mulatta monkey over a six month period utilizing the methods of metallic implantation combined with serial cephalometric roentgenography and a bichromatic vital staining method.

The employment of the vital stains, alizarin Red S and anthracene blue, over the six month period of the study, failed to stain the actively growing bone as evidenced by gross and microscopic analysis of the undecalcified bone preparations.

Interimplant measurements were made across certain bone sutures and the following results were obtained: The zygomaticotemporal sutures showed marked growth separation; the coronal, sagittal and zygomaticomaxillary sutures showed less separation; and the lambdoid sutures showed little separation. Associated resorption of the bone around the implants was more marked in the facial region than in the cranial vault bones, although it occurred in the latter region as well.

Lateral cephalometric roentgenograph superimposition demonstrated a forward and downward movement of the facial bone implants with the exception of the zygomatic process of the temporal bone which moved inferior and posterior. Cranial vault bone growth was evidenced by the superior and posterior movement of metallic implants located across the coronal, sagittal and lambdoid sutures.

The undecalcified skulls were embedded in plastic and hemisected. The right half was semi-serially sectioned by the application of a geo logical lapidary technique (cold process) which proved to be a reliable method of producing permanent, slide mounted thin sections of undecalcified bone.
