Definitions

  • This invention relates to a dental technique and alloy that can be used in orthopaedic stomatology, and especially in dental castings, restorations and cast removable partial devices, including dental prostheses and dentures.
  • the prosthetic device or false tooth application allows to solve tooth defects of the enamel and restore the integrity of the dental arch.
  • the prosthesis design is selected on the basis of what is already currently used in modem dental, prosthodontic practice.
  • the stomatological cast alloy [1] “NiCr-DENT No S vas”, that contains in its composition the following components: Cr-25%; Mo-9.5%; Si, Mn, S-4%; the remainder being Ni.
  • the alloy is characterized by high yield point, high hardness, possibility to be machined with drills of usual instrumental steel, high-tensile oxide film under good adhesion toward metallic basis and ceramic coating.
  • the disadvantages of this alloy are the low biomechanical compatibility, high specific gravity, and the complexity of technology that requires the formation of a deep vacuum.
  • the prosthetic devices made of this prior prototype alloy practically have no shrinkage, they fit on to gypsum models easily thus allowing to reduce the thickness and degree of teeth preparation intended for use with prosthetic devices. Also, these prosthetic devices are not affected by oxidation, thus increasing their service life.
  • the disadvantages of the prototype alloy are low elasticity and low biomechanical compatibility.
  • the fine-structured elements of the prosthetic devices are affected by high-level mechanical loads, for example, the frames of removable partial prosthetic devices, and since they are not elastic, they are weak. In order to increase the strength of the partial prosthetic devices it would be necessary to increase the volume of material and thus to increase the weight of the prostheses.
  • the technical advantages of the invention are an increase in the elastic properties of the new alloy, its related biomechanical compatibility, strength characteristics and strain wear resistance.
  • FIGS. 1, 2 and 3 are views of partial metal frames of the removable prosthetic devices cast from the alloy of the invention.
  • FIG. 4 is a view of a partial prosthetic device cast from the invented casting alloy.
  • the dental casting alloy of the invention comprises, in weight %: Ti: 44-46%, preferably about 45% Mo: 0.2-2.0%, preferably 0.5 to 1.5% Fe: 0.1-1.5%, preferably 0.3 to 1% Cu: 0.1-1.0%, preferably 0.3 to 0.8% Co: 0.1-0.5%, preferably 0.2 to 0.4% Ni balance to 100%
  • Amounts of Mo below the aforementioned lower limit render the alloy difficult to machine or extrude while amounts above the aforementioned upper limit render the alloy too brittle.
  • Amounts of Fe below the aforementioned lower limit reduces the plasticity unfavourably, while amounts above the aforementioned upper limit increase the plasticity to an unfavourable level.
  • the melting temperature is 1130 to 1210° C.
  • the invented dental casting alloy was employed in an experimental trial.
  • the composition was as follows in weight %: Ti-45%; Mo-1.0%; Fe-0.5%; Cu-0.5%; Co-0.3%; the balance to 100% was Ni.
  • This alloy was processed by means of induction casting.
