Here are some tips I've found helpful for me. Reducing the occlusal portion first will give
better access and visibility as well. Then axial reduction then old restorative materials. Remove
any decay and refine the internal walls, break the gingival contacts. Pack cord and refine margin
where needed. Ultradent ViscoStat is a great tissue management agent for bleeding, or use laser.
Check for undercuts. Soak the cord in ViscoStat before you pack the cord. Or use Comprecap or
Traxodent.
You can use a carbide 557 to cut short the shank of your diamond burs so you have more access
for the distal of second molars. I usually like to make the temp before impression to know if I have
enough reduction and any undercuts and how retentive is my prep. ■

I am definitely a lurker on DT, but I had to comment to commend your search for excellence! Thank you for trying to be better! I've not been practicing for as long as you, but I too
have searched for a good technique and I think I've got it down:
1. 330 bur to remove contacts, make initial interproximal margin and create depth grooves
over the occlusal.
2. Large coarse diamond football to reduce occlusal to the depth grooves (I find it easier to
cut out the interproximals so my football has less to do there and then I don't accidentally
touch adjacent teeth).
3. Coarse tapered chamfer bur for margins all around the tooth. (I unintentionally make my
margins slightly too big in my opinion, but I agree with a previous comment. What does
" erasing " a margin mean?)
4. Fine straight chamfer bur to refine margins and walls of prep.
5. This one is my favorite. Fine end cutting diamond bur to smooth all margins.
I hope this helps someone if not the OP! ■

Developing a sequence and sticking to it is critical to your goal. First, and the most important part, is to recognize your approach needs refinement. If I may be so bold, when I look at your
prep and the diamond marks, it appears you are trying to use one bur to go circumferentially
around the entire tooth and then come back with a different one.
You commented on the finish line, now as you get faster you will rarely pick a diamond more
than once so what I'm going to suggest is contrary to that. You might find it easier to prep each
part of the tooth separately. Prep the buccal, then the lingual, then the interproximals, focusing
on creating a continuous depth margin and a smooth one. Then connect all your finish lines. In
this way you can focus on each part of the tooth and not constantly have to move your mirror,
head or patient. I find when I do move around too much, my preps suffer. You usually have to
stop the handpiece as well and it moves, and you have to find where you left off. ■
