Print This PostDr. Croll asks us:
I use Atlantis custom abutments for cement retained crowns and bridges and usually the fit on single units is excellent.
Occasionally for multiple units I have found the fit of bridges to be a little tight. Are any of you using die relief to create space for the cement? I am thinking of telling my lab to use 6 coats of die spacer. Has anybody tried this already?

We have also found that multiple unit implant restorations tend to get “tight” espefcially after ceramic application. We have taken to routinely relieving the inside of our frameworks after fit confirmation by the Dr. If done before and it needs to be sectioned the dr may feel that it fits too loose. This is not a function of Atlantis Abutments, but all cemented multiple unit implant restorations. The longer the abutments, the greater the issues.
I am from Atlantis, and would like to provide input on this topic. For customers that feel that their bridges fit a little tight, we recommend that they request a five or six degree taper as a first solution. This will eliminate time in the lab applying die spacer and is easier and quicker than having to apply six coats of die spacer. Atlantis can make this adjustment with a click of a button for any degree of taper. Just note on your prescription form under “Special Instructions”.
Glad to see James from Atlantis taking the lead on this… one of the reasons why this technology (Atlantis abutments) is so innovative is that the software can make changes to the stock default design parameters as per the clinician or lab’s CDT request.
When doing long spans, the accuracy is so good, and the abutments so parallel, that the frameworks will fit tightly. (Of course this assumes that the implants are reasonably placed). The easiest solution is what James has stated - change the default design settings, and adjust the taper of the abutments… on the Rx.. to the lab or Atlantis. The object here is to REDUCE chair and lab time… and this technology is expert at accomplishing both. Do not modify the metal, or add die spacer if it can be modified first in the design process.
