Outline of Final Research Achievements

Directly milling zirconia computer-aided design (CAD)/computer-aided manufacturing (CAM) crowns from fully sintered zirconia blocks using a 5-axis laser milling system, compared with full sintering by heating milled semi-sintered crowns, was investigated. Results of the present study suggest the superiority of the five-axis milling system in creating a zirconia prosthesis.
The above-mentioned result 2016 (Indonesia) International Dental Materials Congress, the 71st General Session of JSDMD (2018:) I announced the poster in Osaka). Furthermore, I contributed an article to DMJ (Master Journal List publication magazine) in December, 2017 and reached it by accept in April, 2018.
