He explained about ceramic restoration and direct bonding.
The first half of the lecture was about ceramic restorations using both pressure-discharge threads and rubber dams. 
By using the rubber dam at the time of setting and also using the compression thread, we can learn the clinical practice of Dr. Uchiyama who pursues more accurate bonding.
In the case presentation in the latter half of the lecture, he explained the anterior direct bonding by M.R.I.S. step by step.
By the explanation using actual clinical videos, you can learn Dr. Uchiyama's technique as if you were watching it up close. It is an impressive case presentation that leads to the next video.
