The purpose of the present study was to clarify the anatomical basis of the cranio-and maxillofacial rehabilitation using implants. In the present study, 30 cadavers from the dissection room were evaluated. In particular measurements of the craniofacial bones, including height, width, and thickness of the cortical bone were performed. The results were as follows:1. Orbital areaIn the lateral and superior orbital rim of the placement site of implant of orbital prosthesis, the maximal thickness of the inner and outer sides was 16.0 mm, and the minimum was 9. 2 mm. The maximal thickness of the width was 11.1 mm and the minimum was 6. 8 mm. The maximal thickness of the cortical bone was 2.5 mm, and the minimum was 2.1 mm.2. Temporal bone1) At the placement site of the implant of an auricular prosthesis, the maximum thickness of the width was 10.4 mm, and the minimum was 2. 8 mm. The maximum thickness of the cortical bone was 3.7 mm, and the minimum was 3.7 mm.2) At the placement site of the bone anchored hearing aid, the thickness of the inner and outer sides was 8.6 mm. Thickness of the cortical bone was 3.0 mm.3. Frontal and nasal boneIn the center of the frontal and nasal bone, the thickness of the inner and outer sides was 19.3 mm. The thickness of the coronal bone was 3.0 mm.4. MaxillaThe thickness of the inner and outer sites at the site 1 of the maxilla (5 mm distal to the center) was 13 mm. The thickness of the width at site 1 was 10. 1 mm. Tne thickness of the cortical bone at site 1 was 1.4 mm.From these results, the anatomical basis on the cranio-and maxillofacial rehabilitation using implants could be clarified.
