Utilising solid models for preoperative shaping of HAP-TCP ceramic bone substitute: application for craniomaxillofacial surgery

Summary

Recently, the use of a three-dimensional solid model prepared by laser stereolithography have become widely used to simulate cranio-maxillofacial surgery. Moreover, development of high-strength apatite ceramics, composed of hydroxyapatite and tricalciumphosphate (HAP-TCP), has made it possible for us to preoperatively prepare a bone substitute material. A total of 27 models have been produced in 21 patients with craniofacial tumors, trauma, and congenital deformities who required preoperative simulation. In 12 of these cases, the HAP-TCP ceramic implant was made preoperatively, designing them directly on the models. Three representative cases are presented.
