Abstract
A system and method for dispensing prophylaxis paste during dental cleaning procedures which includes a flow control valve, which is actuated by pressure between the prophy cup and the tooth, and also includes a source of prophylaxis paste delivered under pressure.
Claims26
An apparatus comprising:
- a prophy angle having a prophy cup attached thereto;
- a supply of matter disposed internal to said prophy angle;
- and,
- a pressure sensitive valve cooperating with said prophy cup, where said pressure sensitive valve is configured to control a flow of said matter to said prophy cup in a manner that is responsive to a pressure applied at least in part via said prophy angle.
1 more element
An apparatus for cleaning teeth comprising:
- means for transmitting power from a power source moving about a first axis to a second axis;
- wherein said means for transmitting is sized and configured to be inserted in a human mouth;
- means for removing matter disposed on a tooth;
- said means for removing is sized and configured to be inserted in a human mouth;
- means for regulating a flow rate of matter onto said means for removing, where said flow rate is responsive to pressure being applied to said means for removing;
- said means for regulating is sized and configured to be inserted in a human mouth;
- said means for regulating further being configured to permit adjustment of said flow rate while said means for regulating is at least partially disposed within a human mouth;
- and,
- said means for regulating further being configured to increase said flow rate as pressure applied to said means for removing increases.
6 more elements
A method of adjusting a flow rate of matter into a prophy cup comprising the steps of:
- providing a prophy angle and a prophy cup in a human mouth-sized cavity;
- without removing said prophy angle from said cavity, increasing a level of pressure on said prophy cup, by applying pressure to said prophy angle and simultaneously contacting said prophy cup with a rigid object fixed in said cavity;
- and,
- without removing said prophy angle from said cavity and without inserting additional objects into said cavity which cooperate with and regulate said prophy angle, dispensing matter into said prophy cup at an increased flow rate when said level of pressure increases.
1 more element
A prophylaxis material dispensing apparatus comprising:
- a first tooth engaging member, sized and configured to be inserted into a human mouth-sized cavity;
- an elongated member, coupled with said first engaging member, said elongated member configured to transmit mechanical force to said first tooth engaging member;
- said first tooth engaging member further configured to be powered into relative repeated motion with respect to said elongated member while said first tooth engaging member is disposed in said human mouth-sized cavity;
- a pressure sensitive prophylaxis material delivery control, coupled to said first tooth engaging member;
- a prophylaxis material supply coupled to said pressure sensitive prophylaxis material delivery control for providing prophylaxis material to said pressure sensitive prophylaxis material delivery control;
- and,
- said pressure sensitive prophylaxis material delivery control being further configured to cause a variable flow rate of prophylaxis material to be responsive to mechanical pressure applied onto said first tooth engaging member.
