Abstract
A dental abrading tool for use in micro-dentistry that utilizes abrasive dust as the abrasion material, and which provides for effective dust suppression through the use of a water-aerosol spray. The tool consists of a means for the emission of a stream of the abrasive material A spray of water-aerosol is also emitted from the tool in a manner which effectively controls widespread contamination by the emitted abrasive material.
Claims69
A dental abrasion device comprising:
- first delivery means for delivering pressurized abrasive material to a tooth region;
- supply means for supplying a pressurized aerosol mixture of a gas and a liquid;
- and
- second delivery means for delivering said aerosol mixture near said tooth region under conditions sufficient to suppress airborne emissions of said abrasive material from said tooth region.
A dental abrasion device comprising first delivery means for delivering abrasive material to a tooth region, supply means for supplying a pressurized aerosol mixture of a gas and a liquid and second delivery means for delivering a pressurized aerosol mixture toward said tooth region under suitable conditions for retarding the escape of airborne abrasive material from said tooth region.
A dental abrasion tool comprising a head, a nozzle mounted on the head which is further connectable to a supply of abrasive material, supply means for supplying a pressurized aerosol mixture of a gas and a liquid, means for the delivery of the pressurized aerosol mixture of a gas and a liquid to the head and at least one outlet at the head adjacent the nozzle to emit said pressurized aerosol mixture, thereby constituting means for suppressing abrasive material dust.
A method of abrading a tooth, comprising the steps of:
- delivering a first supply of abrasive material to a tooth region in a patient's oral cavity;
- and
- delivering a second supply of pressurized aerosol mixture of a gas and a liquid toward said tooth region, wherein said aerosol mixture has sufficient volume and pressure to form a barrier to airborne abrasive material between said tooth region and said oral cavity.
A dental system comprising a hand tool and a supply means operable to deliver an abrasive material stream and a fluid stream including a pressurized aerosol mixture of a gas and a liquid to the hand tool under conditions sufficient to deliver an abrasive material to a tooth region while forming a curtain to suppress airborne abrasive material emissions from said tooth region.
A method of abrading a tooth, comprising:
- a step for delivering first supply of abrasive material to a tooth region in a patient's oral cavity;
- and
- a step for delivering a second supply of a pressurized aerosol mixture of air and water near said tooth region, wherein said fluid has sufficient volume and pressure to form a barrier to airborne abrasive material between said tooth region and said oral cavity.
A method of abrading a tooth, comprising the steps of:
- preparing a first supply of abrasive material;
- delivering the first supply of abrasive material to a tooth region in a patient's oral cavity;
- preparing a second supply of a pressurized aerosol mixture of air and water;
- and
- delivering said pressurized aerosol mixture near said tooth region, wherein said pressurized aerosol mixture has sufficient volume and pressure to form a curtain, thereby to form a barrier to airborne abrasive material between said tooth region and said oral cavity.
A dental abrasion device comprising first delivery means to deliver abrasive material to a tooth region, supply means for supplying a pressurized aerosol mixture of a gas and a liquid, and second delivery meant to deliver the supply of a pressurized aerosol mixture of a drive gas and a liquid near said tooth region and in the form of a curtain surrounding the tooth region, under suitable conditions to provide uninterrupted passage of the abrasive material to the tooth region for contact therewith and to retard abrasive particles deflecting from the tooth region from passing through the curtain.
A dental prophylaxis method, comprising the steps of:
- delivering an abrasive material to a tooth region under conditions sufficient to condition the tooth region;
- providing a pressurized drive gas;
- mixing water with the pressurized drive gas in order to form a pressurized aerosol mixture;
- delivering the pressurized aerosol mixture to the tooth region, under conditions sufficient to cause the pressurised aerosol mixture to form a curtain around the tooth region to impede the passage of airborne abrasive material away from the tooth region.
