Abstract: A dental implant inserted into a jawbone in order to fasten a tooth replacement is characterized by a shape corresponding to two partially overlapping cylinder-like members (29, 30) that have significantly different diameters. The axis of symmetry (14) of the first member (29) having the larger diameter extends perpendicular to the cortical bone (4) of the jawbone, while the axis of symmetry (15) of the second member (30) having the smaller diameter is tilted by an acute angle relative to the axis of symmetry (14) of the first member (29). The point of intersection (2) between the axes of symmetry (14, 15) lies on the axis of symmetry of the first member (29), within or outside said member (29).

Abstract: The invention relates to a spoon for receiving soft or liquid food. Said spoon has a handle with an attached mouthpiece constructed of soft and flexible material. The aim of the invention is to significantly simplify the manner in which food is received by small children and people with facial paralysis. The spoon has a practical shape in that the mouthpiece is trough-shaped and concave and has a level defining upper edge, whereby the thickness of the mouthpiece in the front and on the lateral side is proportional so that its concave shape can be inverted by the pressure of the tongue (Z) during swallowing and the mouthpiece can adapt to the arched shape of the hard palate (G) in a sagital and transversal direction.

Abstract: An oral hygiene appliance has a spring-elastic working piece, comprising a stamped element made from foam, on the head of an handle. The stamped element is made from closed-cell foam, and only the cells located on the stamping face are opened by the stamping process.
