Department of Prosthetic Dentistry

Introduction of departments

Treatments in our clinic are the restoration of the defective tooth structure and the replacement of the missing teeth for the recovery of the stomatognathic function loss and esthetic disturbances.

For example, we make the fixed restoration with the full metal crown, the resin jacket crown, the bridge, the removable denture and the dental implant in patient’s oral cavities.

Recently we use some kind of esthetic zirconia for these restorations. These materials are expected no harmful for the biological compatibility, less metal allergy, and so on.

During recent years, we had continued to examine state-of-the art crown restoration which is made by hybrid resin CAD/CAM systems in a clinical trial, as the advanced medical technology. This has been successfully applied for Japanese healthcare insurance in April 2014. Recently, we are researching usefulness of polyetheretherketone (PEEK) as crown’s material on clinic. PEEK is a semi-crystalline linear polycyclic aromatic thermoplastic and it became an important high-performance thermoplastic candidate for replacing metal implant components. Our department is trying to find PEEK’s new application in the clinical dentistry.
