Patent number: 4180913Abstract: A filler for an .alpha.-cyanoacrylate dental material comprising a silica powder coated with at least one solid catalyst having a weak catalytic activity to the .alpha.-cyanoacrylate. Solid catalysts include amino acids and acid-amide compounds. The dental material is prepared by mixing an .alpha.-cyanoacrylate with the filler. The mixture is applied to the tooth and a setter composition comprising a basic amine compound having a strong catalytic activity to the .alpha.-cyanoacrylate is applied to cure the dental material.Type: GrantFiled: November 14, 1977Date of Patent: January 1, 1980Assignees: Lion Hamigaki Kabushiki Kaisha, Mitsuharu TakeuchiInventors: Mitsuharu Takeuchi, Satoshi Hayashi, Isao Minemoto

Patent number: 4162576Abstract: An appliance for treating teeth, such as human teeth, by providing them with a reinforcing acid-resistant layer of a tooth decay retarding agent. The appliance includes a vibrator for producing ultrasonic vibrations, this vibrator terminating in an elongated vibratory tip. A casing houses the vibrator and has a tubular open end region in which the tip is at least partly accommodated. This tubular open end region of the casing carries an elastic membrane wall which extends across the tubular open end region of the casing and through which the tip extends so that the tip has a free end situated outwardly beyond this elastic membrane wall. The elastic membrane wall fluid-tightly engages the vibratory tip while surrounding the latter, and the membrane wall maintains this fluid-tight engagement with the tip during vibration thereof.Type: GrantFiled: March 23, 1977Date of Patent: July 31, 1979Assignee: Lion Hamigaki Kabushiki KaishaInventors: Kiyochika Takemoto, Yasuo Suzuki, Yoshihito Ochiai, Syozi Nakashima, Midori Hayashi

Patent number: 4144882Abstract: A device for exposing teeth to radiation of ultrasonic waves while the teeth are contacted by a decay-retarding agent, for forming a reinforcing layer of the latter agent on the teeth. In addition to a generator for generating ultrasonic waves, the device includes a support structure which carries a plate capable of transmitting and reflecting the ultrasonic waves. The latter plate is situated between the generator and teeth toward which waves are generally directed from the generator, so that the latter waves are received by this plate which transmits part of the waves through the plate to the teeth at the side of the plate opposite from the generator while another part of the waves are reflected by this plate away from the teeth which receive the transmitted waves, so that in this way the reflected waves may be utilized to treat additional teeth.Type: GrantFiled: December 17, 1976Date of Patent: March 20, 1979Assignee: Lion Hamigaki Kabushiki KaishaInventors: Kiyochika Takemoto, Yasuo Suzuki, Yoshihito Ochiai, Syozi Nakashima, Midori Hayashi

Patent number: 4144675Abstract: The present invention provides an apparatus for treating the top ends of flexible cords or filaments. It comprises holding means for holding articles having flexible cords, delivery means for delivering said holding means in a predetermined direction, cylindrical grinding means disposed at a position adjacent to a delivery passage for delivering said holding means, and means for rotating said cylindrical grinding means around its own axis and around an axis at right angles to its own axis. By virtue of the feature that the cylindrical grinding means is rotated around its central axis and around the axis rectangularly crossing the central axis, the top ends of flexible cords, such as bristles of toothbrushes, can be polished and ground from all the directions and very smooth and round outer ends can be obtained at high efficiency and high rate.Type: GrantFiled: May 11, 1977Date of Patent: March 20, 1979Assignees: Lion Hamigaki Kabushiki Kaisha, K.

Patent number: 4144646Abstract: A torsional ultrasonic vibrator particularly adapted for treating teeth by exposing them to ultrasonic waves in the presence of a tooth-decay retarding agent which engages the teeth. A shaft which has a central axis has fixed thereto a blade which projects from the latter axis while having a size small enough to be situated in the mouth of an individual to be treated and large enough to extend along a plurality of teeth in the mouth. A vibrator is operatively connected with this shaft for angularly oscillating the same about the above axis at an ultrasonic frequency.Type: GrantFiled: December 2, 1976Date of Patent: March 20, 1979Assignees: Lion Hamigaki Kabushiki Kaisha, Kano Denki Kabushiki KaishaInventors: Kiyochika Takemoto, Yasuo Suzuki, Yoshihito Ochiai, Syozi Nakashima, Midori Hayashi

Patent number: 4127125Abstract: For the purpose of forming a reinforcing layer of a decay-retarding agent on the surface of teeth, a device is provided for transmitting ultrasonic waves to the teeth while the latter are in contact with a decay-retarding agent. The device includes an enclosure which is adapted to contain a medium for transmitting ultrasonic waves, this enclosure including a sheet material which defines a hollow interior space in which an ultrasonic wave transmitting medium is adapted to be located. This sheet material of the enclosure has the property of being impermeable to the ultrasonic wave transmitting medium, so that the latter cannot pass through the sheet material. In addition, the sheet material has the property of transmitting ultrasonic waves therethrough.Type: GrantFiled: December 21, 1976Date of Patent: November 28, 1978Assignees: Lion Hamigaki Kabushiki Kaisha, Kaijo Denki Kabushiki KaishaInventors: Kiyochika Takemoto, Yasuo Suzuki, Yoshihito Ochiai, Syozi Nakashima, Midori Hayashi
