Abstract
The purpose of the present study was to investigate the actual conditions for oral implant therapy in the Hokkaido region. Self-administered questionnaires were mailed to dentists who belong to the North Japan Oral Implant Society in the Hokkaido region to gather information. A total of 44 of the 134 questionnaires were returned. All completed surveys were analyzed through questionnaires collected from 44 general dentists (32.8 percent).
The participants were asked,“How many implant systems do you use in your clinic？” It was found that the majority of responses was one system (28.6percent), followed by three systems (21.5percent), and two systems (19.0 percent). The most commonly used implant systems were AQB (24.4 percent), followed by ITI (17.8 percent), Calcitek and Paragon (15.6 percent). Porcelain fused to metal crowns were used more than resin veneered crowns on the implant supported prostheses. At the incisor and canine, porcelain fused to metal crowns were commonly used. At the premolar, porcelain fused to metal crowns were more used than full cast crowns. At the molar, full cast crowns were commonly used. The most popular retaining method of the prostheses used by dentists was cement retaining, followed by screw retaining, and temporary retaining. The results of this survey suggested that the aesthetic treatment is important in latel implant therapy.
