Abstract

This study aimed to describe the trend in insurance claims for dental gold-silver-palladium alloy in private dental clinics from 2006 to 2020 and examine the association between the trend and the increasing price. We calculated the proportions of dental gold-silver-palladium alloy in inlays and crowns and performed a segmented regression analysis for the annual trend changes in the proportions. In inlays and fillings, the proportion of dental gold-silver-palladium alloy decreased from 13.2% in 2006 to 7.0% in 2020. However, there was no significant downwards trend during the periods with the increasing price. In crowns, the proportion of dental gold-silver-palladium alloy decreased from 93.9% in 2006 to 75.8% in 2020, and a significant trend change occurred during the periods with the increasing price. Since 2006, the proportions of the insurance claims for dental gold-silver-palladium alloy have trended downwards. The increased price might have partially contributed to the downwards trend.
