Definitions

  • the invention relates to a milling block, to a method for producing partial or total prostheses and to a complete milling block system consisting of a first milling block for the upper set of teeth and a second milling block for the lower set of teeth and to a method for providing a partial or total prosthesis.
  • a method for producing a total prosthesis with an upper and/or lower jaw base with the aid of a milling device is already known from EP 0 501 983 B1, the respective base being milled from a synthetic block and data on the oral cavity characterising the contour or topography being used.
  • This method described therein also uses, after preparing the adapted base for the oral cavity, the further procedural step of positioning the required teeth in wax on the upper and/or lower jaw base, the prosthesis being completed by connecting the teeth to the base with the aid of a cold-curing polymer. Next the so-called reocclusion takes place so that the respective patient is provided with an optimal bite according to the latter's chewing movements.
  • a milling block for producing partial or total prostheses may include a prosthesis base to be processed according to the shape of the jaw, on which synthetically moulded teeth, preferably of a full set of teeth, are provided.
  • a method for producing partial or total prostheses may include providing a first milling block for the upper set of teeth and a second milling block for the lower set of teeth.
  • the method may also include determining the contour data of the oral cavity of a patient and preparing and/or processing the first and the second milling block according to the contour data of the oral cavity.
  • FIG. 1 illustrates a milling block in accordance with an embodiment.
  • FIG. 2 illustrates a prosthesis of the lower jaw in accordance with an embodiment.
  • a milling block for producing partial or total prostheses wherein a prosthesis base with synthetically moulded teeth of a full set of teeth is provided that is to be processed according to the shape of the jaw.
  • the corresponding milling block system is also equipped as regards the upper set of teeth and the lower set of teeth independently of the fastening in the mouth.
  • the milling block according to the invention is based on a one-piece arrangement with a first region, which has a prosthesis base that can be processed according to the shape of the jaw, and a second region with a predetermined or standardised arrangement of synthetically moulded teeth or rows of teeth for upper or lower jaw sets of teeth. Therefore, as a preliminary stage for the dental prosthesis a milling block is provided which, in a particularly cost- and time-saving manner, can only be processed, i.e. milled, in its first region, namely the prosthesis base in order to be adapted to the shape of the jaw.
  • the milling block system comprises at least a first milling block for the upper set of teeth and a second milling block for the lower set of teeth, i.e. the preliminary stages of a partial or total prosthesis, which in the respective second region of the first and/or second milling block has a predetermined or standardised arrangement of synthetically moulded teeth or rows of teeth for the upper and lower jaw sets of teeth positioned according to established occlusion principles.
  • the predetermined or standardised arrangement of synthetically moulded teeth or rows of teeth for the upper and lower jaw sets of teeth positioned according to established occlusion principles are non-individualised, prefabricated dental prosthesis parts which do not require any further post-processing.
  • the predetermined or standardised arrangement of synthetically moulded teeth or rows of teeth for the upper and lower jaw sets of teeth positioned according to established occlusion principles takes place according to a selection of prefabricated dental prosthesis parts, i.e. synthetically moulded teeth or rows of teeth according to pre-specified and known positioning systems.
  • the synthetically moulded teeth and the prosthesis base are made in one piece, when producing the milling block a casting or pressing mould can almost be used which therefore also respectively uses just one material for the milling block which advantageously has both a smaller allergy potential and a higher bond strength.
  • the milling block is configured in two parts, it is thus made possible for the first region, that is processed according to the shape of the jaw, to be produced in a standardised manner and to be joined to different teeth, likewise already positioned on a second region, which are of different sizes and have different factors.
  • the prosthesis base can be configured flexibly, simplified adaptation to the oral cavity and adaptation to the shape of the jaw of the respective patient can be allowed for.
  • Materials featured as particularly advantageous for the milling block and for the milling block system are, among others, so-called PMMA plastics, as are also thermoplastics, organically and inorganically filled plastics and also low-allergy plastics.
  • PMMA plastics as are also thermoplastics, organically and inorganically filled plastics and also low-allergy plastics.
  • any form of ceramic in particular glass ceramics, leucite-reinforced ceramic, aluminium-reinforced ceramic, oxide ceramic, zirconium oxide ceramic, infiltration ceramic, feldspar ceramics, lithium disilicate ceramic. It is also conceivable to use materials that have been sintered, but that still require a further production step.
  • the milling block or the milling block system can also be used with a combined dental prosthesis.
  • the milling block or milling block system can also include just two types or more.
  • the milling block or the milling block system according to the application can also be used in particular for the production of partial prostheses if at the very least opposite quadrants of the upper or lower sets of teeth can be used. Due to the positioning prepared for the teeth in the occlusion position, after inserting in and adapting to the corresponding jaw region post-processing of the teeth is therefore also practically unnecessary.
  • One particularly advantageous production technique for the milling block or for the milling block system is the possibility of inserting the selected teeth, pre-polymerised, in the occlusion position in the first region of the prosthesis base and then only undertaking the final polymerisation upon joining to the second region of the prosthesis base.
  • the respective upper and lower jaw prosthesis it is made possible for the respective upper and lower jaw prosthesis to be prepared and produced in one piece and form- and force-fitted, and so it has a lower allergy potential and a higher bond strength.
  • FIG. 1 a milling block 1 is shown which has a prosthesis base 3 which is processed according to the shape of the jaw on which synthetically moulded teeth 5 of a full set of teeth are already provided.
  • the synthetic teeth are already worked such that the teeth are aligned according to an occlusion position and so can interact optimally with the upper jaw (not shown).
  • the prosthesis base and the teeth are made in one piece, and so the production process has been simplified.
  • FIG. 2 the completed total prosthesis of the lower jaw is shown, the prosthesis base 3 already being adapted to the oral cavity.
  • FIG. 2 clearly shows how the shape of the oral cavity has been milled out of the prosthesis base, the teeth 5 , which are aligned in the occlusion position, remaining untreated. It is thus made possible with the method according to the application that only by adapting the prosthesis base is there a complete total prosthesis the occlusion of which is coherent and does not necessitate any further procedural step, such as for example adaptation in an articulator.
  • a further procedural step as specified for example in the prior art, namely subsequent alignment by arranging the teeth in wax in order to achieve the occlusion position, is not necessary with the method according to the application.
