Accurate analogs for prostheses using computer generated anatomical models

Pre-surgical planning for cranial and facial reconstruction includes preparing a computer generated jaw or skull model for determining a locational position for a dental implant, a surgical bone implant to repair missing bone in the cranium, install ear prostheses, and/or install nose prostheses. The computer generated jaw or skull model is made from medical imagery and computer aided design. A surgical guide is prepared with oversize holes in registration with analogs for the dental or surgical bone implants to be inserted at the locational positions determined by a dentist or surgeon in the jaw or cranial skull model. The surgical guide is fitted atop each analog, and the surgical guide is bonded to the jaw or skull model at a predetermined angle of the analog in the jaw or skull. The surgical guide is removed from the model attached to the law or skull of a patient for accurate drilling during the dental or surgical procedure for insertion of the implants into the jaw or skull of the patient.
