Title:
TOOTHBRUSH ALLOWING SIMULTANEOUS BRUSHING BOTH DENTAL ARCHES
Document Type and Number:
WIPO Patent Application WO/2008/047492
Kind Code:
A1
Abstract:
Although so-called whole periodontal toothbrushes, by which the occlusion
face and the lip and tongue sides of the dental arches can be simultaneously brushed,
are advantageous in allowing easy and quick brushing and so on, they have never
been widely used because of having a large brush width, requiring a manual fabrication
procedure and a welding procedure with the use of a solvent and, in its turn, being
expensive. A toothbrush fabricated by primarily molding a couple of brush-filling
bases, each having two lines of brush-filling holes, using a hard plastic material,
providing a space for enclosing dental arches therein between bristles by using
a brush-filling machine, then forming both brush-filling bases (1, 1'),
a linker (2), a handle (3), a space (10) having a desired chain-shape and so on made
of a soft rubbery plastic that is compatible with the material employed in the
primary molding with the use of a jig capable of giving an inclination of about
150o to about 160o to the brush-filling face, wherein three
or four brush-filling lines are formed on one face of the toothbrush bases, and
bristles in one or two inner lines are cut short while longer bristles are filled
in each of the outermost lines so as to enable brushing with the sides of the individual
brush-filling lines and prevent the toothbrush from slipping off from the dental
arches.
