  • Publication number: 20080193893
    Abstract: A water spray intensity system for providing water to a dental workpiece based on dynamic conditions experienced by the handpiece. The dental workpiece is a dental structure, typically in the mouth of a patient. A periodic function of the handpiece may include a motion such as a periodic motion of a tool of the handpiece, the speed of the rotating tip or some measurable parameter such as the torque experienced by a rotating tip assembled to the handpiece. Instead of providing water at a constant flow rate, the periodic function of the handpiece, such as torque or tip speed, is made by measuring a parameter associated with the handpiece. The water spray intensity system then automatically adjusts the flow of water from the handpiece based on the sensed parameter or periodic function to improve cutting efficiency.

The main valve is formed with a valve chamber having an inlet port and an outlet port, and the valve comprises a valve seat and a valve member cooperating therewith. The valve member is movable between a closed position in which it engages the seat and blocks flow of fluid from the inlet to the outlet and an open position in which it is spaced apart from the seat and enables such flow. The sensing means includes an exhaust to the atmosphere and exhaust shutoff means actuable for closing the exhaust. The housing and main valve are formed with a passage enabling restricted leakage of fluid from the main chamber to the sensing means for exhaust to the atmosphere when the valve member is in the closed position. The leakage fluid is in communication with the valve member and when pressurized applies a force urging the valve member to the open position.

  • Patent number: 4446456
    Abstract: A dental treatment apparatus having a plurality of dental instruments which are adapted to be deposited and releasably retained in an instrument holding device. The dentist is a position to store for the individual treatment instruments operating data of his own selection which will constitute fixed values. The treatment instrument will begin with these fixed values when taken into operation. However, the dentist can deviate from the fixed values and vary the operating data. The fixed values, as well as the varied operating data can be read off by the dentist on a display arrangement. After termination of the treatment, the treating instrument upon again being placed in operation commences at the stored fixed value. A data converter provides that the operating data are indicated on the display arrangement. It is possible to call up, by means of a single selecting sequence, the sets of data informations typical for treatments by all instruments which are to be employed.

  • Patent number: 4430062
    Abstract: In a dental apparatus, in which each of a number of instruments is controlled by a control circuit common to the instruments, which are connected with a common operator unit having a control member which is movable in planar directions out of a home position, auxiliary functions not related to the instrument operation may be carried out by means of the common operator unit by switching the apparatus to a second mode of operation, when all the instruments assume respective resting positions in an instrument carrier. Moreover, also auxiliary functions directly related to the instrument operation may be carried out by the common operator unit in a first mode of operation by actuating the control member thereof with a movement different from the instrument energizing movement. The movement for energizing such an auxiliary function may have another direction and/or a shorter duration than the instrument energizing movement.

  • Patent number: 4386910
    Abstract: The invention concerns a console specifically designed for the suction tubes of suction units used in dentistry.The console basically comprises a box-like shell which is furnished with a collector, maintained in a state of vacuum and connected to the suction tubes, inside of which is a filter drawer through which pass all the fluids sucked in by the tubes. There is a compartment located in the top of the box-like shell, its top open, which contains the pneumatic and electrical command devices necessary to the console's functioning.The console further comprises a cover in which are located the forked housings for the tubes, which can be attached directly to the top of the box-like shell or which can be connected to the box-like shell by means of articulating arms which allow adjustment of the position of the cover and, consequently, the tubes' housings, with respect to the box-like shell, which will normally be fixed to the dentist's main assembly.

  • Patent number: 4382786
    Abstract: A dental treatment installation comprising at least one dental handpiece having an air operated drive motor and an outlet for discharging operating media used for dental purposes, a spray handpiece, a control arrangement for controlling the supply of operating media to the handpieces, and a storage device for the handpieces having storage switching-means which are arranged to place the handpieces on stand-by to receive operating media upon extraction of the handpieces from the storage device. The control arrangement includes supply sleeves having ducts for supplying operating media to both types of handpiece, couplings for releasably coupling the supply sleeves to the handpieces, and a foot-operated device for regulating the supply of operating media to the handpieces and including first switching-means for controlling the supply of air to drive the motor of the dental handpiece and second switching means for controlling the supply of spray to the dental handpiece.

  • Patent number: 4375963
    Abstract: A control unit is provided for supporting a multiplicity of dental handpieces of the high-pressure air-driven type, and which includes a plurality of holders for removably supporting the individual handpieces. Each of the holders is mounted on one end of a corresponding arm. The other end of the arm serves as a pinch block. Each arm is pivotally mounted on the frame of the control unit. An actuator is mounted on the frame of the control unit adjacent to each holder, and when a handpiece is inserted into the corresponding holder it engages the actuator and forces the corresponding arm to turn and to move, together with the holder and handpiece, to a down position. The other end of the arm then pinches one or more flexible tubes against a pinch bar in the control unit when the holder is forced to its down position.

  • Patent number: 4351634
    Abstract: A dental delivery unit carries a number of dental instruments in nests. Upon selection, one nest is extended carrying its instrument to the dentist's group. Selection is accomplished by a priority system. Associated with each nest is a switch. Activation of any switch starts a selection period by a priority system. At the end of the selection period the nest corresponding to the last to be activated switch is extended by the priority system.If two switches are activated together the nest corresponding to the furthermost switch is extended.

  • Patent number: 4340368
    Abstract: A hand held power tool, particularly of the type of a dental handpiece or the like is provided with power shut-off means disposed directly within the handle. The shut-off means is mechanically connected with a suspension means for suspending the hand piece or the like power tool such that the weight of the tool shuts off power supply to the tool. In a particularly preferred embodiment, a dental handpiece is disclosed wherein the suspension means is a magnet, whereby the handpiece can be suspended on any ferromagnetic surface without having to reach to a suspension fork which, in the known devices, is itself associated with a shut-off valve. The basic idea of the invention has broad application in many different fields of technology.

  • Patent number: 4230452
    Abstract: The specification discloses a multiple dental handpiece control system in which lifting one handpiece out of its hanger blocks supply of power and coolants to all other handpieces. Each handpiece has an individual control unit and a blockout unit. When a handpiece is lifted from its hanger, it actuates a valve to cause a piston in its control unit to shift to a condition causing supply of power and coolant fluid to that handpiece and cutting off power to the corresponding pistons in the other control units thereby preventing supply of power and coolant fluids to the other handpiece.
