Thoughts on taking final impression for a crown on implant?

Do the crowns properly fit the model? If so the impression may be the problem. Both the labs I use consider triple trays inappropriate for implant restorations. I use full trays and high quality impression material. No problems with fit. You can use a bite reg including a healing cap on the implant and include that cap in the lab items. Might try a different lab. Too tight contacts can be created by damaging the model's proximal surfaces.

1. I assume that you are using the same lab for your regular C&B and not having the same problem. 2. What you are doing is okay, a decent work-around, but the fit may not be as good on the abutment as if the crown was made on the actual abutment, i.e. possible future cement wash-out problems. 3. I agree with Ljo, how is the fit on the model? Personally, I've been doing mplants for 30+ years and I still set the analog into the impression, paint die stone on the analog to lock it into the impression (sometimes need to use Tru-Soft as tissue subsititute), and after the die stone has hardened pour up the rest of the model. I know, very old school, but I very, very rarely have a problem with what I get back from the lab.
