Crowns on 8 and 9
I posted this case on Facebook yesterday and I thought I would post it here as well.
Patient came to my office (works in the dental field) and was concerned about the wear on 8 and 9.
Now from first look, it seems as you might be able to be conservative with composite. However, we have to understand "how" the wear was caused... In this case her older lower bridge was a bit too long incisally and causing "pathway wear" on the lingual that also damaged the incisal edge. If you just simply add composite, it's likely not to fix the underlying issue.
The plan was to do full coverage crowns on 8 and 9. Why full coverage crowns? Because I wanted to both lengthen the teeth, restore proper lingual contour, and slightly increase overjet to give her more room to function... we also planned on lowering the incisal edge on the lower bridge
Step #1 was to quickly mockup with composite. We mocked up both the incisal edge and the lingual surface. By doing this, the occlusion was obviously very high... This gave me a roadmap on how much to reduce the lower bridge:
Here are the preparations and scans with Primescan:
We chose to do Biogeneric using the "mockup" as a guide... we chose a Vita Morphology in the database. Here is the "biojaw" proposals and final designs:
And here is the final result...Vita Trilux Forte
Very nice case, I still struggle to get the shapes you do. Did you stain and characterize these also?
Does using the morphology make you have to do less contouring>?
Yes... contoured, stained and glazed.
The morphology in BioJaw definitely helps. Most importantly, it gives you good symmetry. Then i use the incisal variation tool.

Another thing that helps is milling in EF mode. It definitely takes longer, but gives you much more detail and takes less time contouring.
Great case Mike. Biogeneric keeps getting better and better.
Excellent! Great contour, texture, shade and customization. Nice long and tight midline....
