Abstract
A tooth cleaning device for optimal tooth cleaning comprises, on a U-shaped carrier (109), tufts of bristles (180), which are placed against the tooth using pressure bubbles (149) under equal cleaning pressure on both sides. With this arrangement the tufts of bristles (180) are fitted to individually self-positioning rocker arms (174, 178'), in order to also engage in the spaces between the teeth, which are difficult to access. With the aid of a further pressure bubble arrangement (147) using phase-shifted pulsating pressurization, with reference to the pressure-generating bubbles (149), a wiping movement of the tufts of bristles (180) with cleaning pressure is generated in the direction from the gum towards the crown of the tooth, in counter-direction without bearing pressure on the tooth.
Claims49
A tooth cleaning device with at least one cleaning means mounted to a base arrangement, the device comprising:
- a first driving means for automatically driving said cleaning means in an oscillating manner in a first direction;
- and
- a second driving means controllable independently from said first driving means, for driving said cleaning means in a second direction substantially perpendicular to said first direction whereby said first and second driving means form a composite drive adapted to drive the at least one cleaning means relative to a handle supporting said cleaning means.
A method for cleaning teeth comprising the steps of:
- applying at least one cleaning means to a tooth to be cleaned;
- driving said cleaning means relative to said tooth to be cleaned;
- generating a first drive for automatically oscillating substantially along a first axis extending substantially parallel to a longitudinal axis of the tooth;
- generating a second drive for automatically oscillating substantially along a second axis perpendicular to said first axis, said first and second drive being controllable independent from each other;
- superimposing said two oscillating drives along said first and second axis to form a predetermined composite resultant drive for the cleaning means;
- and
- applying said composite drive to said cleaning means,
- whereby said composite drive is relative to a handle means supporting said at least one cleaning means.
A method for cleaning teeth, the method comprising the steps of:
- applying at least one cleaning means to a tooth to be cleaned;
- driving said cleaning means relative to said tooth to be cleaned;
- generating a first drive for oscillating substantially along a first axis substantially parallel to a longitudinal axis of a tooth;
- generating a second drive oscillating substantially along a second axis perpendicular to said first axis;
- superimposing said two oscillating drives along said first and second axis to form a composite drive for the cleaning means along a non-circular path;
- applying said composite drive to said cleaning means;
- controlling a pressure generated by said cleaning means on the tooth, such that said pressure is greater when said cleaning means moves from a gum to a crown of the tooth than when said cleaning means moves from said crown to said gum.
