Abstract

A denture retaining system and a denture bar constructed to be affixed in a human mouth, the denture bar including a distal end, lingual-side surface, vestibular-side surface, bone-facing surface and superstructure-facing surface opposite the bone-facing surface. The bone-facing surface at the distal end is relieved from the superstructure-facing surface at the distal end by an angle of between 10° and 25° relative to an axis perpendicular to a longitudinal plane passing through the lingual side and vestibular side surfaces of the denture bar. The system also includes an overdenture superstructure having a distal surface that substantially conformingly mates to the denture bar distal end when the overdenture superstructure is positioned against the denture bar superstructure-facing surface, and is coupled to the denture bar by at least one attachment element located at a position to an anterior side of a first molar position.

• A61C 8/00 - Means to be fixed to the jaw-bone for consolidating natural teeth or for fixing dental prostheses thereonDental implantsImplanting tools
• A61C 13/225 - Fastening prostheses in the mouth

Abstract

A prosthetic tooth includes an artificial tooth body and a liner at least partly coupled to the tooth body. The liner includes an elastically deformable material that will at least allow the tooth body to move from an unloaded position under a load, and cause the tooth body to move back towards the unloaded position when the load is reduced. Dentures (full and partial) containing one or more of the described prosthetic teeth, and associated methods of making a prosthetic tooth and a denture are also disclosed.

• A61C 13/107 - Prostheses for temporary restorationVestibular masks
• A61C 13/07 - Linings or cushions therefor
• A61C 13/08 - Artificial teethMaking same
• A61C 13/103 - Fastening of artificial teeth to artificial base material, e.g. to palates or to adjacent artificial tooth connected to base material by additional connecting member, e.g. knob or bar
