ActiveUS20090092944A1Short maintenance periodMinimal traumaDental implantsExtract toothThin cortical bone
The invention concerns a non rotation-symmetric but root-analogue or tooth socket-analogue dental implant of the same size and shape as the root of the extracted tooth with macro retentions protruding from the implant surface (107, 113, 116).Macro retentions (107, 113, 116) are strictly limited to surface areas of the implant in the interdental space next to spongy and thick bone and in case of the last molar, facing the bone at the end of the tooth row. The diameter of the dental implant in transverse direction next to the thin cortical bone buccal and lingual / palatinal is identical to the alveolar bone or preferably stands back to avoid any pressure induced resorption and fracture of the thin cortical bone layer, respectively, at any cost.

Device for cleaning interdental spaces

Individually packaged coils of dental floss are packed in a succession of separable. The package can be a tubular sheet structure with segments formed between transverse lines of attachment at which the floss is cut and the segments are separable by a lateral perforation. Tearing a separated single segment in half allows the floss to be extended between the free ends of the floss, each captured in the remaining portions of the weld lines at opposite ends of the segment. The segments can be formed from two facing sheets with welds along both lateral edges and across the transverse lines between segments. Alternatively, an integral sheet can be folded to form one lateral edge and attached at the other edge. The sheet material can be polymer coated paper or a transparent plastic.

Toothbrush and toothbrush head for said toothbrush

A toothbrush and toothbrush head with a bristle carrier, on which a bristle section featuring a multitude of filaments is arranged. At least one filament is provided with a taper on its free end with a shape other than a rotationally symmetrical shape to preserve a high flexural strength of the filament in one direction. The taper is a flat-pressed scarfing such that the filament has a greater flexural strength with respect to a first lateral axis than with respect to a second lateral axis perpendicular to the first lateral axis in the region of the taper. The flat-pressed scarfing at the point of the filament improves penetration into the interdental spaces, while the higher geometrical moment of inertia of the wide side reduces the bending of the filament during use.
