Definitions

  • the present invention relates to a toothbrush the structure of which is conceived in such a way as to produce a thorough cleaning and massaging action on the gingival structures in addition to the customary cleaning of the interdental spaces.
  • Toothbrushes have been available for some time now in which the height of the bristles is not constant, but differentiated in such a way that cleaning surface defined by the bristle tips takes on a broadly “anatomical” form, i.e. so as to adapt to the mean curvature of the users' dental arches.
  • a toothbrush whose set of bristle bundles presents a rake; in this type of toothbrush, the height of the bristles increases progressively and linearly with the increasing distance from the end of the toothbrush opposite to the handle.
  • the "raked” toothbrush affords various advantages over traditional toothbrushes.
  • the rearmost molars can be reached easily, even in subjects with a tight rim of the mouth or cramped vestibular space, achieving, moreover, satisfactory removal of food residues from the gingival pockets and dental plaque with reactivation of the gingival circulation.
  • a toothbrush with a head, handle and bristle set characterized by the fact that the bristle set consists of two groups of bristles in each of which the height of the bristles decreases progressively from the edge of the brush head towards its longitudinal axis in such a way that the tips of the bristles produce an elongated hollow depression running parallel to the longitudinal axis of the head.
  • the particular arrangement of the bristles produces the positive effect of achieving simultaneously a delicate massaging of the gums by the longer (and therefore softer) bristles, access in any direction and from any angle to the interdental spaces on the part of the intermediate bristles, and, lastly, a vigorous cleaning action on the dental arches by the shorter (and therefore stiffer) bristles.
