Abstract　： [Abstract] This paper describes the advantage of using photocurable resin skull models (PRSMs) of patients with jaw bone disorders. The skull of three patients with trauma and/or jaw deformity was CT scanned in 2-mm slices, and life-size models were reproduced from the CT data. After removing the dental portions of the PRSMs, the plaster casts were made and integrated into the models (IPRSM). Surgical corrections were simulated on the models (IPRSM simulated surgery; IPRSM-SS) exactly as they would later be performed in the actual operation. Titanium miniplates for actual surgery were prepared by bending into the suitable alignments according to the information obtained by the IPRSM-SS. After all three patients were successfully operated on, cephalometric analysis was performed subsequently between the patient and on the IPRSM-SS that had undergone simulated surgery. The cephalometric analysis showed that the frontal and lateral plane differences between IPRSM-SS and actual patients were small: ranging from 0 to 2 mm. The pre-formed mini plates fit as planned; only a few had to be adjusted during the surgeries. The technique of building life-size model and performing simulated surgery on it have attractive advantages: 1) by seeing a model, patients quickly and easily understand the problem that needs to be corrected, 2) having pre-formed titanium miniplates already prepared before the operation, actual operating time is shortened, reducing the risk to patients, Because of these advantages to patients, we recommend and appreciate the prevalence of the technique of producing an IPRSM and simulating surgery on it.
