I learned this building technique from Kenneth Guthrie. I couldnt productively use his exact technique so I made changes to suit me.
He used a #8 brush for the entire build, That took me too long so I use a spatula, a small pointed carver, and a brush.
12 minutes is the max time I want to spend on a posterior build. After that Im loosing money.
Im happy with an average of sub 10 min builds. Bi's are faster, large odd shaped molars longer, so it averages out.
If a Dr is paying more per unit I spend more time with detail in the build. Some Drs send pics for posterior shades and want them matched. But there is only so much you can do with a molar.
Ive been doing it this way for over 25 years since I first took Ken's courses.
I have no idea where he is now but if your out there Ken, thank you so much I have made alot of money from the techniques you shared.
This prep is a bit short on room. I had to reduce a spot on the opposing lingual cusp. The lingual is also underpreped which seems typical.
Shade A2
I opaqued the occlusal Intensive Incisal so it wouldnt look opaque in the thin areas.
If it was part of a splint and in the esthetic zone I would have opaqued the margin in the D range. D2 or 3. The rest A2.
I use a wet tray. Powers are always mixed and wet I just add when they get low.
I mix Ivoclars two building liquids(P & L) 50/50. One was to gummy the other didnt stay wet long enough. Gives me the best of both worlds.
Cervical Dentin. I use the Cervical Dentin D2/3 for most everything because that is all Ivoclar has with Inline. It would be nice if they had more.
I dont use the Oclussal Dentin Orange or Brown as much because it is not very forgiving. It is very strong and must be used sparingly or I will be grinding it out.
I can get sloppy with the CD D2/3 and it still blends in.
I like to pick up enough with my spatula to make one swipe across the occlusal and be done with it. It takes a couple at the cervical and I feather it upwards. This should only take seconds.
