ABSTRACT:
A pre-formed tooth crown comprises a connection at the lateral surfaces capable of bridging three-tooth crowns. The connection further comprises a male fastener at one lateral surface and a female fastener at the opposing lateral surface, where the male fastener has a center hole and the female fastener has a corresponding central through hole. In order to form a crown bridge with at least three-tooth crowns, the male fastener of one tooth crown can engage with the female fastener of an adjacent tooth crown. While after the crown bridge is located onto the patient's teeth, a lining material stuffed inside the tooth crowns can be then squeezed from one tooth crown to an adjacent tooth crown via the center hole and the central through hole for ensuring the binding within the crown bridge.
