Immediate facial rehabilitation in cancer patients using CAD-CAM and rapid prototyping technology: a pilot study.

<bold>Purpose: </bold>This study describes the workflow in a procedure to create a provisional facial prosthesis for cancer patients using digital and rapid prototyping technologies without the need for supporting craniofacial implants.<bold>Materials and Methods: </bold>An integrated workflow procedure aimed at the construction of provisional silicone prosthesis was used to rehabilitate a facial disfigurement in a patient who had undergone ablative surgery of the midface. A laser scan of the defect was obtained, and a digital model of the patient's face was constructed using virtual mirroring of the healthy side and referencing the "Nose Digital Library."<bold>Results: </bold>The missing volume of the face was reconstructed, and a rapid-prototyped mold was devised to process the silicone prosthesis. A provisional eyeglasses-supported prosthesis designed with a CAD/CAM-projected titanium substructure was connected using the micro-components of implant prosthetic devices.<bold>Conclusions: </bold>The workflow described herein offers a viable procedure for quickly restoring facial defects by means of provisional prosthetic rehabilitation.
