Purpose: The aim of this study was to estimate the tendency of metal-free restoration for premolar teeth.
Methods: We counted the number of CAD/CAM resin crowns, resin jacket crowns and metal crowns to set for premolar teeth at the Nippon Dental University Hospital from April 2014 to March 2016. Complications (loss of retention, fracture, etc.) and setting procedures were evaluated regarding CAD/CAM resin crowns with questionnaires.
Results: The total number of CAD/CAM resin crowns, resin jacket crowns and metal crowns were 474, 196 and 818, respectively. The number of CAD/CAM resin crowns increased gradually and accounted for 51.3% of crown restorations for premolar teeth in March 2016. After 2 years, the complication rate was 5.7% and only 37.8% of cases were with sandblasting.
Conclusions: The rate of CAD/CAM resin crowns increased and it was suggested that CAD/CAM resin crowns are used as crown restorations for premolars. However, some early complications occurred, and the results suggested that indications and adhesive procedures should be taken into consideration.
