Splinted Crowns With CEREC


When restoring implants, there are circumstances when it is necessary to splint crowns together. I was recently doing a case on #29 and #30 which required a splinted restoration. 

 

 

 

When fabricating this implant bridge, one thinks it is necessary to use a bridge block. In fact, the Mill Phase defaulted to use a 32mm block for the veneering structure (splinted crowns) of this restoration.

 

 

 

However, even though the C14 e.max block has a yellow exclamation, choosing that block in fact indicated that it would likely fit.

 

 

We were in fact able to mill this abutment bridge veneering structure out of a C14 block. This is a nice time and cost savings for you. So, next time you are milling a small bridge, try a smaller block like a C14 just in case it might fit!


So the work flow for Chairside, is :
design 2 separate implant crowns
split the abutments
mill 2 separate abutments
place individual abutments on model or in mouth, image, and redesign bridge?

I think this is necessary in chairside to do the reimage and redesign because you cannot design an implant bridge in Chairside.

I think you can in inLab.


Mike , can you explain us how you proceed ? Cerec or Inlab? On the first picture ,are the crowns individuals ? or they are already mixed ? Many thanks for your response .


Michael, you are correct. In inlab you can design this as a regular implant bridge and let the software split everything as it does for a single unit chair side restoration.

In the chair side, you would do exactly what Michael described- design two restorations, split them, mill them and then seat and reiamge and design a bridge.


Hi Bertrand-
This case (the first picture) was an implant bridge that was done with Inlab 4.2.3.
I designed the bridge, split into two hybrid abutments, then milled the splinted veneering structure out of a size 14 block.
You could do it with chairside easily as well, just would require a rescan at this time
