Definitions

  • the invention relates to an arrangement for connecting laterally from each other dental prosthetic items to be arranged, in particular a prosthetic part with an anchor or Attachment part, by gluing, consisting of at least a pair of Fasteners or model parts that with connected to the dental prosthesis to be connected or are connectable and at least of which one embraces the other.
  • Adhesive connections become known (Geiger: "Attachment technology", p. 167 ff.).
  • a Secondary attachment part with a glue stick provided while the to be connected Prosthesis part with a matching eyelet is provided by shaping the model with a thin layer of wax coated glue stick is molded.
  • glue stick and eyelet fit essentially the same shape one another, i.e. that the mutual situation of Secondary attachment part and prosthesis part through those to be connected by gluing Surface parts of the glue plug and the eyelet is specified. A subsequent correction is not provided.
  • Another disadvantage of known technology is that the Modeled and cast adhesive cones first must be before the part to be connected can be modeled.
  • a known principle follows the same principle Connection arrangement brochure "PRECI-BUT" the company ALPHADENT p.v.b.a., Antwerp), the from a tooth to be glued into a denture There is a female and a male.
  • the for Certain admission of the matrix in the prosthesis Cavity is in the cast model by a Placeholder determines its diameter is as large as the diameter of the largest Circumference of the die, so that this in is essentially free of play in the cavity. Therefore the adhesive layer is between these parts in the prospectus also as "relative thin ".
  • the prospectus recommends that Gluing only in the patient's mouth to make any pass errors before Establish the connection and if necessary by reworking the surfaces to be glued the prosthesis or the matrix are corrected can.
  • an artificial tooth is known (DE -A-22 476 49), which consists of a root part and a crown that has an elastomer if necessary, prefabricated intermediate layer with each other are connected. Because these parts in the projection lie on top of each other on the chewing level and therefore essentially only compressive forces the intermediate layer needs to be transferred not to be glued and therefore can be prefabricated, keeping together compared to the small expected Tractive forces come about in that a undercut pin and one undercut hole over the elastic Intermediate layer like a push button work together.
  • the elastomer Intermediate layer can be introduced in liquid form and be hardened, but is also in this connection neither gluing necessarily revealed yet.
  • the invention has for its object a Connection arrangement of the aforementioned Way to create a fitting connection of the dental prosthesis and a subsequent one mutual position correction after their Individual production permitted.
  • a cold-curing agent is expediently used Potting compound used, preferably a cold curing synthetic resin, amalgam or the like. This is because particular advantage of the invention Implementation of the connection by the Allows dentist in the patient's mouth. At extensive bridge associations so far required for merging the Individual parts to produce a separate cast (Literature: loc. Cit.), Whereby nevertheless No connection inaccuracies could be excluded. The Cumbersome and inaccuracies of the known method are by the Avoided invention. However it is if desired, of course possible, the compound of the invention laboratory and then possibly with such To make casting compounds based on any properties processing in Mouth of the patient not allow for example due to increased potting or Hardness temperature or due to its toxicity in the monomeric state.
  • the invention also includes the possibility of a connection in the mouth of the patient first of all by the potting compound of a preliminary Hardening is exposed to such an extent that using the connected parts Appropriate caution without mutual Deformation can be removed again after which the actual curing for example using elevated Temperatures is caused in the laboratory.
  • potting compound expediently such a material that in cured condition is rigid to thereby create a accordingly rigid, comparable to soldering To create connection.
  • a expedient elastic element separate from the rigid casting compound inside or outside the Connection area provided.
  • an elastic material applicable or applied and the remaining space with the hardening Potting compound can be filled or filled.
  • the fasteners can in the prefabricated material and for example by soldering to the connecting parts are connected. Instead of of course it is also possible the fasteners at the Casting manufacturing of dental prosthetic items integral with them. It is advisable to use this prefabricated model parts made of wax or Plastic, which in the usual way with the Model parts of the dental prosthesis combined will.
  • the shape of the fasteners in one Cut across the release direction can vary depending on the Requirements are selected differently, For example, web, circle, oval, cross or star-shaped. Combinations of such or other forms are possible.
  • connection arrangement can besides her Connection function also for other purposes serve, for example as a pontic or Stump for a crown.
  • the formation of the gap is for the Success of the compound of the invention of crucial importance.
  • the distance between those to be connected Surfaces should be as small as possible so that the Potting properties similar to those of one Can develop adhesion.
  • it has to Game for the ex post Correction options should be sufficiently large. Individual shaping would be considerable Include errors.
  • the invention therefore provides that for the representation of the In between a special wax or Plastic model part is provided.
  • too inner connecting element can be a corresponding plastic model part provided be.
  • the model part for the Intermediate space also in connection with an as prefabricated inner connecting element Metal part can be used, for example with is connected to a secondary attachment.
  • Embodiment includes the interior Connection element or model part one cone-like thickened part on one in the Connecting direction of the web protruding from it, the pin direction transverse to Connection direction runs.
  • connection direction is the direction understand the those to be connected Dental prosthesis connects.
  • the across provided pin direction allows the Fasteners using parallel brackets position, separate and assemble.
  • the outer connecting element or Model part is useful in cross section omega-shaped, the Omega opening as a bridge opening part of the Bridge includes, while the spigot inside the further than the web opening Interior lies.
  • the width is the Web opening expediently less than that parallel measured thickness of the cone-like Part. That means the inner Connecting element or model part with his thickened cones not through the web opening, but by one at one end of the outer Connecting element or model part lying Insertion opening can be inserted the direction of insertion transverse to Connection direction runs. That the Insertion opening is opposite end at least partially closed to the before Insert the inner connecting element or Model part in the outer connecting element or molding part spent potting compound to keep it in during assembly and to act towards that end To absorb forces.
  • the outer Receives connecting element or model part thereby the shape of a side to form the Bridge opening slotted mug, which turns to its opening complementary to the shape the pin of the inner connecting element or model part narrowed, preferably conical.
  • the space model part is also conveniently at one end in the form closed on one side slotted cup, at its narrower end, that of Insertion opening of the outer Fastener corresponds to it after modeling the outer part of the model can be pulled out. To this end should it go from its closed to that other, open end towards a constant or have decreasing wall thickness. When pulling this out, either Gap model part or the outer Deform the model part a little bit elastically. In order to this is possible, the space model part and / or the outer model part be resilient. All model parts should fit together exactly during the Modeling to take a defined position.
  • FIG Connecting element 1 which within a Surrounding part 2 contains a cavity 3 which is open at 4 slots and differs from the in Fig. 11 visible upper opening to his Bottom flared.
