- •Not allowed when major decay or fracture is absent or the buildup is unnecessary for retention

- •Not allowed on the same tooth and date as a post-and-core service
- •Not allowed with a direct filling, inlay, or onlay
Published threshold: Decay or fracture must leave the final restoration needing the buildup for retention
