Abstract
Recentry, various lingual indirect bonding systems are intermingled in the world.
I think digital systems are very important in the future.
However, I can't introduce them yet, because there are some problems of the precision and the cost.
And, an analog system has various methods of fabrication, however, it needs skillful laboratory work.
In this paper, I describe about one method of advantages of an analog system. That doesn't to fabricate set up model and transfer tray of upper and lower jaws at the same time, the way to fabricate set up model and bonding on the teeth either upper jaw or lower jaw first.
