    • The invention concerns an instrument for setting a crown (4) or a sealed prosthesis on a natural or prosthetic support by generating a couple of forces between the occlusal surface of the stump (3), and the basal surface of the crown (4). The instrument consists of an indented intermediate portion (C) and a working portion (D), which may constitute an extension of a handle (A), and a tapered intermediate portion (B). When it is inserted in a groove previously performed by the practitioner at a supposed level of the occlusal part of the stump (3) along a plane substantially parallel to the occlusal surface of the crown (4), said working portion (D) enables by a physical action to exert a couple of forces between the respective occlusal surfaces of the stump (3) and the basal surface of the crown (4). The couple of forces being generated substantially in the vertical axis (F) of the tooth or implant, the instrument enables to limit the traumas for the patient, to preserve the support base, to safeguard the prosthesis for future resetting.

    • A method and apparatus for setting and removing a cemented, retrievable prosthodontic appliance by means of a levering instrument (21) applied to the gap between two substantially parallel surfaces (19, 20), the first surface being a flat-topped ledge of a window (22) on the lingual aspect of a dental prosthesis (1) and the scond surface being at least one opposed step or ledge on an artificial implant abutment (60). A conformal, removable plug (30, 50) of durable polymer fills and is securable within yet removable from the window in the completed restoration. A narrow channel (73, 74) is provided in a dental abutment post to allow excess dental cement to flow out of the interstitial space between the dental abutment (34) and the overlying prosthesis (33). During the seating of the prosthesis (33) the excess dental cement is channeled to and extruded from a preferred collection point for easy removal. Hydrostatic pressure and trapped gasses that would tend to lift the prosthesis into a nonfitting position or form a weakened cemented bond of uneven thickness are prevented by this apparatus and method to relieve pressure.
