What is the best process and material for a crown for a bruxer?
Tooth is a bottom right molar that has a root canal, a defective crown, and multiple cavities under the crown. He cannot afford to lose this tooth because it's on the main side of the mouth he chews on.
He is a bruxer and seriously grinds his teeth at night (the crown on the root canal tooth has the enamel worn down on it, it's just metal).
Because he is about to treat severe osteoporosis with bisphosphonates, he needs something with very tight margins on the gum line, that’s extremely durable, that will last and not get worn down or break, etc.
