We surveyed the restorations fabricated for outpatients at the Tsurumi University Dental Clinic during the ten-year period, from October, 1972 to March, 1983.
The results were as follows:
1) The fabrication rate of the fixed partial dentures and aft complete dentures of all prosthetic restorations changed very little in this period.
2) The rate of the post crowns the jacket crowns of all single artificial crowns decreased remarkably, while that of the full-cast crowns and resin facing crowns increased but slightly.
3) The Platinum-Gold-Alloy has taken place of 20 K-Gold-Alloy as the material of the single artificial crowns.
4) Both porcelain-fused-to-metal crown and the resin facing crown have been increasingly used as the abutment of the fixed partial dentures.
5) In cases of one missing tooth, the space previously occupied by the missing tooth was mostly restored by the fixed partial dentures, it was restored by the removable partial dentures instead of the fixed partial dentures.
