This patient presented with heavy bruxing. So the Dr planned on doing a full mouth but didn't want metal occlusals. So he went with ZR. On the upper he prepped singles 2-14. 2-4 are FCZ 5&12 are ZR occlusals with cut backs for vennering porcelain. 6-11 are ZR linguals with cut backs for vennering porcelain. On the lower the patient had a partial so we created 3 bridges, 18-20, 23-26, and 27-31, with 21 and 22 being single crowns, all out of FCZ.
So I origanially had done a diagnostic wax-up for approval. Once we recieved the impression we had to transfer the wax-up onto the new prepped model. Then scan the wax-up, scan the preps, dies, and design the crowns to fit the diagnostic wax-up. Since the wax-up was created on on the mounted prepped models and waxed with perfect occlusion. So when I designed the crowns I knew if I stay within the wax-up my occlusion will be "spot-on"!! So I scanned and designed the upper first, then milled it out of wax so I could check my work. Make sure occlusion was good, as well as contours of FCZ. Once I got the green light, I started on the lower and followed the same steps, keeping the design within the wax-up. Then milled them too.
This was a fun case, long procces but fun!! I hope I get to do more like this in the future.
Oh yeah here are some pics of the design, and milled wax units(once I get the ZR milled, sinterd, and stained more pics will follow)!!!
