Definitions

  • This invention relates to a dental instrument according to the preamble of claim 1, to be used especially in connection with repairing cavities of teeth.
  • the absorption spectrum of light sensitive materials is usually quite narrow, typically much narrower than that of the incandescent and halogen lamps generally used as light sources in traditional light curers. Efficiency of these lamps having a wide emission spectrum in view of producing radiation relevant to curing is thus already basically quite low and the intensity is further decreased upon their ag- ing or when damaged, which may even become a risk in view of successful curing of the material to be polymerised.
  • light curing devices which include as light source co ⁇ ponents, among others, light emitting diodes, or LEDs.
  • the light is produced in the body part of the device and the radiation received from the light source or sources is guided to the object through the tip part of the device with the help of a light conductor, such as an optical fiber.
  • Light curing devices containing LED groups and in which the tip of the device is formed of an elongated and bent light conducting element which extends essentially parallel with the body of the device are presented e.g. in the DE patent publication 199 43 393 and in the WO publication 00/13608.
  • Such instruments generally comprise a hand piece and a modelling tip attached thereto.
  • Plugger instrument and light curer are used in con- nection with tooth filling by first modelling filling material in a tooth cavity with the modelling instrument and thereafter curing (hardening) the material with help of the light curing device.
  • the filling operation includes several successive modelling and light curing stages. Then, working is somewhat awkward and slow as one must repeatedly use in turns first the modelling instrument and thereafter the light curing device. Two handed work, especially, is then slow and as far as four handed work is concerned, use of the light curer disturbs assistant's other tasks or postpones them.
  • the object of the invention is to come up with a dental instrument especially for use for both modelling and curing of tooth filling material by which one will be able to lessen many of the abovementioned problems of the prior art instruments.
  • the object is to lessen the need to stretch and/or to bow down for seeing the subject being operated on which lies behind the instrument despite that the light source is placed substantially close to the subject being operated, that is in the essential proximity of the tip of the instru- ment, to enable a good light guiding efficiency.
  • the object of the invention is embodiments that may be realized without a need for using special materials more expensive than accustomed yet still creating a rigid enough construction considering the intended use of the instrument.
  • the construction of an instrument according to the invention thus includes a handpiece and at least one tip part joining to the hand piece and consisting of at least one part comprising a first end and a second end.
  • the first end of the tip part is fixedly or detachably attached to the handpiece and the tip part is arranged to consist of a construction which coirprises a modelling part fixedly or detachably attached to the tip of the second end of the tip part or in the es- sential proximity of said tip and protruding from the tip part, the modelling part being arranged for modelling tooth filling material and to be translucent or to include a translucent component.
  • a means for generating light used at least for curing tooth filling material Arranged at the tip part or the modelling part joining to it there is a means for generating light used at least for curing tooth filling material.
  • the dimensions and forms of the tip part, at least at the essential proximity of the second end of the tip part, or the dimensions and forms of said second end of the tip part itself are arranged such that when the instrument is observed at its position in the patient' s mouth regarding operating on one of the premolars or molars, i.e. from an angle with respect to a central axis of said tip part, or, from the direction the person performing the operation sees the instrument at such an instant, said second end of the tip part or said part of the tip part lying at the essential proximity of the tip part, only partially blocks a view to the premolar or molar in ques- tion.
  • the instrument as a whole is realized such that when the instrument is at that position, none of its parts at least completely blocks the view for the person performing an operation to the premolar or molar being operated on.
  • the instrument comprises both a modelling part for filling material and a means for generating and delivering light to the subject being cured with high efficiency, that is means both for modelling filling material and for curing it, and when not only the actual technical function of the instrument but also visibility to the subject to be worked on has been taken into account in its design, especially visibility to the problematic molar area, performing a tooth filling operation is relatively easy even without an assisting person.
  • the instrument provides the operation typically awkward for the dentists can be mentioned when light curable materials are used in which a contact is created between two teeth, regarding which operation the invention provides the possibility simultaneously and with the one and the same instrument both to cure the filling material and to press on a desired target in the operating area.
  • the instrument according to the invention and especially one accord- ing to its preferable embodiments makes possible taking the component emitting the curing wave length close to the subject in patient's mouth which is to be cured and thus directing light to the target at high efficiency.
  • success in the curing is more reliable than e.g. with many prior art instruments upon use of which a significant distance remains between filling material lying at the bottom of a tooth cavity and the light curing head.
  • the invention together with its preferable embodiments also makes possible, for example, realization of the parts used for modelling filling material as detachable and disposable yet as relatively inexpensive.
  • the invention makes em- bodiments possible in which regardless of certain short dimensions of the instrument, a rigid enough structure may be achieved which still may be realized by using relatively inexpensive materials and manufacturing techniques customary in the field.
  • the invention also makes possible realization of a modelling-curing instrument such that as far as its shapes are concerned, it corresponds with the other instruments typically kept in an instrument holder of a dental care unit, whereby in the dental care environment one may place it on the instrument console of a dental care unit.
  • Re- alization of the instrument in accordance with a preferable embodiment of the invention as essentially cylindrical instead of as pistol-like also makes possible using the light curing-modelling instrument according to the invention with similar grip as the other typical dental care instruments.
  • Such an instrument takes much less space on an instrument tray often used in dental care environment than many of the prior art light curing devices.
  • Fig. 1 presents a basic construction for an instrument according to the invention
  • Fig. 2 presents a second embodiment of the instrument as seen from the side and in which the central axis of a handpiece and the central axis of a tip part is arranged at an angle with respect to each other,
  • Fig. 3 presents a third embodiment of the instrument as seen from the side and in which the direction in which the modelling part of the instrument extends from a tip part is arranged to deviate from orthogonal,

  • the handpiece (10) is elongated and its central axis is arranged to be essentially parallel with the central axis of the tip part (11) , but the handpiece (10) may be of some other shape as well.
