ABSTRACT:
A dental anchor for securing a superstructure to a tooth understructure, the dental anchor having a forward elongated anchoring portion for insertion into a channel extending into the tooth understructure. A coaxial, elongated retaining portion extends from the anchoring portion and has a non-circular cross sectional configuration to provide displacement resistant properties for retaining the superstructure. A depth-limiting portion is integrally disposed between the anchoring portion and the retaining portion for limiting the depth of insertion of the anchoring portion into the channel. The depth-limiting portion has a frustro-conical section which sits into a countersink formed at the upper end of the channel in the tooth understructure. A dental tool is provided to form a limited depth channel simultaneously with a countersink in the tooth understructure for use in conjunction with the dental anchor.
