Flexible dimension crown shells |
摘要 |
A temporary or long-term provisional crown includes a shell having a top wall defining an occlusal surface, a buccal sidewall, a lingual sidewall, and opposite mesio-distal sidewalls, connected to the top wall and buccal and lingual sidewalls and spaced apart to define a central cavity to fit over a prepared tooth. A quantity of resin is disposed in the central cavity of the shell and is preferably shaped to conform to a prepared tooth. Two U-shaped windows arranged in one or both of the mesio-distal sidewalls permit resin to protrude mesio-distally from the cavity to contact an adjacent tooth. A window in the top wall extends mesio-distally to permit resin to extrude on to the occlusal surface. The occlusal window can be hourglass-shaped.
