The material in all of the literature shows it exposed. I think there is a light cure sealer to fill the void, I see no reason why the base has to be in this material rather than completely encapsulating it in the veneering resin. I guess its more about inter arch space and joint size more than anything else. I have a tech call tomorrow with Bicon.
As for restorations on Bicon, its just another Morse taper tap in abutment, out here in the Palm Springs area they are quite popular with a few surgeons. We have done a handful of larger cases, while they are not my favorite implant they most definitely have made me money over the years.
The fudge factor on this material looks huge, the material must flex in some manner to absorb load, the concept to me is fast but the longevity is what has me worried. When I get the disk I hope it gives me some info on CAM setting to optimize cutting, it probably cuts like PMMA but the fibers I am curious about how the resin react to specific rpm/feed rate.
