I gotta chime in here,
The abrasion of opposing dentition has been well documented for a very long time. I was waiting for someone from removable to respond but they didn't. When a denture is made today, it's made using plastic teeth or some form of resin based tooth. Back in the day, and some of you dinosaurs...oops, i mean dynamo's.....remember dentures use to be made using porcelain teeth. The problem was that the porcelain teeth would just abrade the hell out of the natural dentition, that's why they went to what they have now.
As for the hypoxy apetite restorations, that was very interesting, they made a restoration so close to natural dentition that it was acceptable to tooth decay....wowzer, how cool is that....lol
Lastly, Low-fusing porcelain has a lower abrasion rate, that's what needed to be stated.
