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.

Although varicella zoster virus (VZV) infection commonly occurs in the oral and maxillofacial region, tooth exfoliation and alveolar osteonecrosis are relatively rare complications. We describe two cases of tooth exfoliation and alveolar osteonecrosis caused by VZV infection of the trigeminal nerve and review the literature. A 66-year-old man and a 38-year-old man were referred to our hospital because of tooth exfoliation. The first patient had a history of spinocerebellar degeneration, and the second had a history of chronic myelogenous leukemia. Tooth exfoliation occurred on day 21 and day 25 after the onset of VZV infection, respectively. Clinicopathological examination in the first patient revealed actinomyces infection. Panorama x-ray films obtained previously in the second patient revealed no evidence of severe periodontal disease before VZV infection. These findings suggested that tooth exfoliation and osteonecrosis by VZV infection were not only caused by existing severe dental infectious disease, but also by various factors such as multiple oral bacteria, tissue reaction to VZV infection, and compromised status.

Osseointegrated implants have begun to be used not only in general practice in dentistry but also in various clinical situations in the maxillofacial region. The process has yielded three problems: the spread of application, new materials and diagnostic methods, and management for difficult situations. This paper presents basic data and clinical guidelines for new applications, it investigates the characteristics of the materials and the usefulness of a new diagnostic method, and it studies effective techniques for difficult cases.The results obtained are as follows: 1. Investigations into the spreading application1) The lateral and superior orbital rim have sufficient bone thickness and width for the implant body to be placed.2) Osseointegrated implants, especially by the fixed bridge technique, are not recommended in the craniofacial bone and jaws of young children.3) Implant placement into bone after/before irradiation must be performed in consideration of impaired osteogenesis, the decrease of trabecular bone, and the time interval between implantation and irradiation.2. Investigations into materials and diagnostic methods1) Hydroxyapatite-coated and titanium implants should be selected according to the characteristics of the materials.2) A dental simulating soft may also be applicable in the craniofacial region.3. Investigations into the management of difficult cases1) Hyperbaric oxygen therapy (HBO), bone morphogenetic protein (BMP), and tissue engineering should be useful for improving the quality and increasing the quantity of bone where implants are placed.2) Soft tissue around implants placed in the reconstructed area should be replaced with mucosal tissue.The data obtained here should be useful for increasing the efficiency of osseointegrated implants, but further basic research is required in the future.
