  • Publication number: 20110072604
    Abstract: A revolutionary three-dimensional brush, specifically designed to maximize performance and provide complete and comprehensive coverage to each surface of the user's teeth on the occlusal, buccal and lingual side. The maximum potential of this brush is accomplished by the three brushes, each covering a different area of the tooth surface in one stroke. The flexibility of the wing allows the brushes to expand and contract in accordance to the diameter and shape of the teeth. When cleaning the front teeth, the brushes will be more contracted, whereas when cleaning the molars, the brushes will be more expanded. Each brush, the lingual, buccal and occlusal contains bristles specifically arranged in evenly spaced rows to allow for a sweeping motion which provides a powerful cleaning to the cervical gingival and proximal gingival areas. This is in contrast to current brushes which contain bristles that are rigid and have no space causing them to pile up together lacking free movement.

  • Publication number: 20100205760
    Abstract: A manually driven toothbrush creating the same force, effect and rotation as the electric powered toothbrush. The oval head is smaller in circumference to the handle, to allow the flexible movement between the two pieces and stimulate the pushing of the stem against the pillar of the first rotator cog, thereby creating the rotating motion of the three brushes. During use of the toothbrush, the applied force of the hand combined with the friction of the bristles against the tooth surface and the spring and stem between the two segments set in motion the three interlocked cogs to which the bristles are embedded causing the bristles to rotate accordingly. This oppositional rotation pressures against the teeth going back and forth, removing the plaque from high surfaces of the teeth with merely the force of a hand. Such movement and rotation, prevents abrasion, massages the gum, while also providing for 360 degree coverage of the tooth surface.
