There is described a dental prosthesis for forming a friction fit attachment to a dental implant or dental connector. The prosthesis comprises a release device comprising a release member that is movable relative to the prosthesis from a first position to a second position. When the release member is in the first position the release device is not operable to impart a separating force to a friction fit attachment between the implant or connector and the prosthesis and when the release member is in the second position the release device is operable to impart a separating force to a friction fit attachment between the implant or connector and the prosthesis.

Described are compositions and methods for the removal of zinc-oxide eugenol-based temporary cements or root canal filling materials from a variety of surfaces including surfaces inside the oral cavity, such as teeth, as well as surfaces of objects located outside of the oral cavity, such as instruments and prostheses. In certain compositions, the resin-dentin bond between permanent cements and collagen-containing surfaces can be increased. The compositions are non-toxic, can be used inside the oral cavity, and do not require special disposal procedures.

A handling device for a dental tool having a) a body having an elongated shape configured to receive a prying load from an operator; and b) one or more receptacles through the body configured to retain at least a portion of a dental tool and allow an engagement portion of the dental tool to project therefrom substantially perpendicular to a longitudinal axis of the body; wherein the engagement portion is adapted to contact a portion of a dental covering along only one of a facial side or a lingual side of the dental covering and by being wedged between a gum-line and the dental covering; and wherein the one or more receptacles are configured to transfer the prying load from the body to the engagement portion of the dental tool.

A frictionally-retained detachable dental attachment assembly or anchor device is designed to attach a dental appliance with a tooth root or implant. The assembly includes a denture attachment housing for securing in the dental appliance, an abutment attached with a tooth root or implant, and a compressible retention member with a first end in fixed attachment with the cap and a second end in snap engagement with the abutment via a frictionally-retained ball secured within a cavity of the abutment. The retention member is formed using a compressible material to allow the ball to compress and the retention member to flex while inserting the ball into the cavity. Additional friction-retained and fixed attachment configurations of the dental anchor device are provided, along with methods of securing a dental appliance in a subject's mouth by means of the friction-retained and fixed attachment dental anchor devices.

A tooth loosening device comprises a body having a tooth contacting portion connected to a handling portion. The tooth contacting portion has a tooth contacting member including one or more surfaces adapted to contact a tooth, and the handling portion includes a manipulation member. The tooth contacting portion can be inserted into a mouth having a tooth in need of loosening, and the manipulation member can position the tooth contacting member so that the one or more surfaces contacts the tooth in need of loosening. The tooth in need of loosening can then be loosened by manipulation of the tooth loosening device. A vibrating mechanism can also be provided to apply vibration to the tooth in need of loosening.
