Abstract: An instrument product comprises a medical hand instrument (101) and a radio frequency identifier (102) readable from a distance away from the radio frequency identifier. The radio frequency identifier is at least partly covered with cover material (103) attached with adhesive material to a surface of the medical hand instrument so that the adhesive material is in contact with both the cover materia! and the surface of the medical hand instrument. The cover material can be the same material as the adhesive material, or the cover material may constitute a cover element which comprises a cavity for the radio frequency identifier and which is attached with the adhesive material to the surface of the medical hand instrument.

Abstract: An instrument cassette (100, 200, 300) for handling instruments comprises a body section (101, 201, 301) for holding the instruments and a radio frequency identifier (102, 202, 302) readable from a distance away from the instrument cassette (100, 200, 300). The radio frequency identifier (102, 202, 302) of the instrument cassette (100, 200, 300) facilitates tracing operations, such as for example disinfection, sterilization, reparation, and clinical use, directed to or carried out with a set of instruments handled with the aid of the instrument cassette (100, 200, 300). The instruments can be for example medical and/or dental hand instruments.

Abstract: The invention relates to a hand instrument for manual use in dental care, which includes a substantially elongated handle (2), to at least one end of which is arranged a construction for detachably connecting a head part (3) extending substantially from the central axis of the handle (2) and possibly including at least one bending. The construction by which the handle (2) and the head part (3) is arranged detachably connected includes a tightening element (4) axially positioning itself between the handle (2) and the head part (3).

Abstract: A medical or a dental instrument comprises an operative portion (101) for operations according to the purpose of use of the instrument, a center portion (103) mechanically connecting to the operative portion, and a radio frequency identifier (106) located on the center portion and capable of being read from a distance of the instrument. The instrument further comprises a tubular handle portion (104) provided to surround the radio frequency identifier and at least a part of the center portion, the tubular handle portion being cast on the instrument so that the material of the tubular handle portion is adhered to the material of the center portion. Thus, the tubular handle portion acts not only as the handle portion but also as at least a part of a fixation system attaching the radio frequency identifier to the instrument. An instrument of such construction is easy to keep hygienic.

Abstract: An odontological device to guide occlusion of an individual. The device contains a U-shaped arch with concaves on the side of both the lower jaw and the upper jaw. The bottom surfaces of the concaves form an isthmus separating the concaves from one another. The isthmus includes blanks for individual teeth and uniform, continuous hollows for at least two teeth. The lower jaw side of the device has a lower wing constricting a tongue at least sideways.

Abstract: An odontological device and device series to guide an individual's occlusion and a method to be used in selecting an occlusion guidance appliance device to be used in orthodontic treatment. This kind of device contains a U-shaped arch with a lower surface on the side of the lower jaw and a higher surface on the side of the upper jaw, an in both of which there are concaves in which to place the individual's teeth, and where the bottoms of the concaves form of the isthmus separating the concaves from one another. According to the invention, the isthmus includes blanks meant for individual teeth and uniform, continuous hollows meant for at least two teeth to guide the teeth in the required direction, and the lower jaw side surface has a lower wing constricting the tongue at least sideways, and it helps the device to remain in place in the individual's mouth.

This kind of device contains a U-shaped arch with a lower surface on the side of the lower jaw and a higher surface on the side of the upper jaw, and in both of which there are concaves in which to place the individual's teeth, and where the bottoms of the concaves form the bridge separating the concaves from one another. According to the invention, the hollows designed for the back teeth consist of uniform compartments, which start from the second premolar and continue towards the molars at least to the area where the second permanent molar will erupt. The presented device is suitable for use in all dental arch developmental phases.

Abstract: A dental hand instrument (10), comprising a handle (11) with parts (12a, 12b) at its ends. The end of each neck part is provided with a coupling element (15) designed for the connection of replaceable tips (20) and oriented in the same direction with the neck part. The coupling element is a socket or pin (19) extending in the same direction with the neck part and allowing a corresponding concentric pin (21) or socket (26) of the tip to be fitted into/onto it. The socket of the coupling element may be provided with slots (17), and the inner surface of the socket has a circular or cornered cross-sectional form. The neck part and coupling element of the hand instrument are preferably made of stainless steel and the tip is made of steel, aluminum, plastic-coated aluminum, steel or titanium.
