Supra structure abutment holder as well as process for providing a bonding gap

A system comprising

• a supra structure abutment holder comprising a clamping device (12), and an auxiliary device (26), wherein the auxiliary device comprises a tractive device (28) and a flat block (30),
• a supra structure (16), and
• an abutment (14),
• wherein the supra structure and the abutment are clamped between the auxiliary device (26) and the clamping device (12) and are held in positive-fit engagement with each other,
• wherein the clamping device (12) comprises threads for adjusting a height, relative to the auxiliary device (26),
• wherein the clamping device (12) is both disposed along and adjustable along a longitudinal axis of the supra structure (16) and the abutment (14),
• wherein the flat block (30) is provided to be flexible, or is provided with a surface which is flexible and facing towards the supra structure, and is elastically deformed by an incisal or an occlusal surface of the supra structure (16),
• wherein the flat block (30) is provided on one side, with depressions for accommodating the occlusal surface of the supra structure and/or, on the other side, at least one depression for accommodating the incisal surface of the supra structure,
• wherein the tractive device (28) overlaps the flat block (30), such that the flat block (30) exerts pressure in the direction of the supra structure (16),
• wherein the clamping device (12) is configured to clamp the supra structure (16) and then abutment (14) in place along the longitudinal axis,
• wherein the positive-fit engagement made up of the supra structure (16) and the abutment (14) is accessible from a side while clamped between the auxiliary device (26) and the clamping device (12), and a bonding gap (18) is visible.
