 note = {application/pdf, Considering the presence of metal allergies and the sharp rise in the prices of precious metals, full–coverage restorations made of titanium have been covered by Japanese insurance since June 1, 2020. The clinical application of these restorations is expected to increase in the future. However, due to its high melting point and high affinity to oxygen at high temperatures, titanium has not been widely used in prosthetic clinical practice. This study aimed to survey the actual use of full–coverage metal restorations at Matsumoto Dental University Hospital. Patients who had full–coverage metal restorations placed on their molars from June 1 to December 28, 2020, were consecutively enrolled, and data on the type of metal, placement site, and time were recorded. Besides, the dentists who used titanium restorations (Ti–Rs) were given a questionnaire. We asked them to rate their impressions of Ti–Rs in comparison with full–coverage restorations made of Ag–Pd–Cu–Au alloy (Pd–R) in six categories, including occlusal adjustment, polishing, and luting operations. In all, 338 molars received full–coverage metal restorations. Ti–R was used in 33 cases and Pd–R in 305 cases; 14 upper and 19 lower, 12 first molars, 18 second molars, and 3 third molars received Ti–Rs, while 137 upper and 168 lower, 174 first molars, 174 second molars, and 3 third molars received Pd–Rs. Seven dentists responded to the questionnaire survey. Many dentists stated that Ti–R was more challenging to use than Pd–R for occlusal adjustment, polishing, and adjustment time. On the other hand, most of them stated that the luting process was similar for both. Besides, Ti–R was favorably evaluated in terms of metal allergy. The number of patients who received Ti–Rs increased during the study period, suggesting that Ti–Rs will be a commonly used metal allergy–friendly prosthetic in the future. We plan to continue the survey and study the prognosis.},
