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.

Abstract: An improved method and apparatus for effecting delivery of a chemical solution useful in the softening of tooth caries and/or plaque in a patient's mouth utilizes a reciprocating piston-type pump having flow and pressure regulation for injecting a pulsating jet stream of the solution at a controlled rate and pressure, in combination with a separate heater device adjacent an applicator maintaining the temperature of the solution at or near body temperature as it is delivered to the mouth.

Abstract: A router for performing finishing operations on a dental model having a housing with a base in which a motor is positioned. A storage compartment mounted on the base includes a pivotal cover. The cover forms a horizontal work platform on which the dental model is supported during the operations. The motor extends into the storage compartment and a tool is secured to the shaft for vertical projection above the work platform through a hole in the cover. Apertures in the cover permit dust to fall down into the storage compartment from which a vacuum extracts the dust. A novel method of routing dental models is provided wherein the dental model is placed on a horizontal work surface and finished using a vertically oriented tool.

The slide is provided with at least one peripheral slot (6) in which is engaged a bearing (8) carried eccentrically by a shaft (7) rotatably mounted in a cylindrical housing (9A) of a radial extension (9) of the body (1).The head is notable particularly in that the slide may be disengaged by retracting the bearing (8).

Abstract: A clamping arrangement, especially for the clamping or gripping engagement of dental implements, consisting of a receiving sleeve which is rotatably supported in a handpiece and is connected with a rotary drive, which includes at least one rod-shaped elongated clamping element exerting a radially inwardly directed pressure against the shaft of the implement which is inserted into the receiving sleeve because of contact against an inclined track oriented perpendicular to the longitudinal axis of the clamping arrangement. The handpiece can pertain to a straight handpiece or to an angled handpiece (elbow) with an angled headpiece.

Abstract: This invention relates to dentistry, and more particularly to cosmetic dentistry, where for aesthetic objectives it is desirable to remove a small amount of the patient's tooth enamel to modify tooth color. A procedure is described using an applicator and compound which provides accelerated treatment time in stripping away a sufficient amount of the outer layer of the tooth enamel to provide the necessary tooth color modification. The applicator has two functional ends. One end has a containment pocket for holding the compound, and a second end for high pressure scouring of the tooth enamel. The compound comprises an enamel softening acid, such as hydrochloric acid, in the concentration range of between 6%-16% in combination with an abrasive particulate material. The abrasive material should have a hardness greater than 6.0 as measured on the Mohs hardness scale for greatest effectiveness.

The pin or post has a head, neck and shank and is an elongated member formed by crimping the midpoint of a bar, folding the bar in a predetermined configuration about the rings so that the pin or post consists of side-by-side sections joined only at the top of the head portion.

Abstract: A guide attachment for guiding a dental treatment tip such as a dental bur is provided. The guide attachment is composed of a guide member for guiding the dental treatment tip and a fixing member for mounting the guide member to a dental handpiece in which the dental treatment tip is accommodated.

Abstract: Ring for the construction of temporary or permanent dental crowns.The ring is constituted by two molded half-shells (1, 2) which carry coupling elements (3, 4; 5, 6) rigidly fastened together in pairs by bonding, welding or any other method of rigid attachment which is capable of ensuring cohesion of the assembly in such a manner as to constitute in combination a shuttering mold for the filling product which is intended to restore the tooth.

Abstract: An improved dental flossing material and method of making the same is disclosed. The flossing material in the form of a tape is formed of expanded polytetrafluoroethylene (PTFE) folded longitudinally to form a pair of laminae defining a recess therebetween in which an abrasive or non-abrasive cleaning material is disposed. During the cleaning procedure, material flows from the free edges of the tape to become deposited upon the surfaces of the teeth and adjacent gingiva. Due to changes in light transmitting quality of the tape, a visual and reversible indication of prior use becomes apparent. In the manufacture of the tape, the PTFE, which is microporous, is coated on one surface thereof with a moist dentifrice which may be suitably thinned using a volatile vehicle.

The mandrel includes a wheel anchor station which allows quick axial fitting and removal of a disposable polishing wheel.

Abstract: A dental working stand comprises a stationary working table with a lower cabinet forming an instrument module and/or an upper cabinet.To facilitate the dentist's access to the lower and/or upper cabinet during sole working the lower and/or upper cabinet, respectively, are pivotal around a vertical axis from a first position in which the front of the cabinet faces the position of the dental nurse at the front of the working table to a second position in which the cabinet front faces a dentist's postion at one end of a patient's support.

Abstract: A precision haircutting tool primarily designed to facilitate the cutting of one's own hair or someone else's hair easily and uniformly. The thumb of the hand used to hold the hair for cutting is slipped through the thumb ring and the finger guide (or stem) is allowed to extend between the index and 2nd fingers of the same hand. The hair is then combed upwards with the opposite hand and the hair is grasped between the same index and 2nd fingers between which the finger guide is being held. With the thumb resting on the head, the fingers are then slid up the stem to the finger stop and the protruding hair is cut above the fingers. By following a systematic pattern, the hair can be easily cut to the same length all over the head. By using various sizes of the device, a variety of hair lengths or combinations of hair lengths can be attained.

Abstract: An instrument particularly adapted for use in dentistry but capable of a wide variety of other applications and including a divider-caliper type instrument typically having two members of equal length and substantially corresponding configuration pivotally secured to one another wherein opposite ends of each member is defined by different sized points. A scale format is formed on an exposed surface on at least one of the members and is based on the golden proportion of 1 to 0.618. Accordingly, a plurality of scale settings are disposed in predetermined spaced apart relation to one another based upon formulized calculations resulting in use of the caliper instrument in dental applications including direct oral procedures, dental laboratory techniques, cephalometric analyses as well as aiding in the establishment of arch form, tooth size and outline form as well as cusp-fossa proportions and the accurate and simple placement of developmental grooves.
