Definitions

  • the present invention relates to an impression tray for producing denture impressions having a receiving surface, a dental impression box for producing denture impressions, and a method for producing denture impressions.
  • dental impression trays are used for the production of dental prostheses, such as crowns, bridges, partial and full dentures. These impression trays or impression trays are used by the dentist to take the impression. Depending on the intended use, pre-made spoons are used or individual spoons are made. Ready-made spoons are factory-made impression trays that are used for taking impressions on dental prostheses, situation models and normal jaw conditions for working models. Individual trays are made on models of the patient with which more accurate impressions can be taken.
  • the dental prosthesis parts In order to make the dental prosthesis parts, first an accurate impression or an impression of the denture or a part thereof, the so-called negative form of the patient's teeth.
  • a viscous impression material is introduced into an impression tray and then pressed onto the series of teeth to be removed.
  • the corresponding teeth form as negative.
  • the impression material usually based on silicone, polyether or alginate materials, hardens in the mouth and can then be removed from the mouth with the impression tray. Subsequently, the impression is trimmed, for example with the help of a scalpel for the so-called second impression.
  • a model of the dentition situation is then made of special hard plaster. This model serves as a working basis for the dental technician who can model and make dentures or dental prostheses.
  • the object of the invention is therefore to provide means by which the potential patient / user can automatically, without dental knowledge, mold his own teeth, so that if necessary, the subsequent production of dental prostheses by dental technicians / dentists can be easily performed.
  • impression tray according to the preamble, characterized in that the impression tray above and below the receiving surface each having an impression layer for position marking.
  • a dental technician or dental layman can produce a denture model at any desired location.
  • Gebißmodellen can easily, quickly and inexpensively the shape and position of the upper and lower front and side teeth of any people are secured, especially of young people who have no dentures or need.
  • the dental technician can make a new denture or denture by copying the denture model.
  • the natural anatomy of the dentition predefined by nature can thus be reproduced in case of later loss, fractures or deformities of the teeth.
  • the papilla incisiva a reference point that does not change throughout life and thus at any time Position and position of the upper anterior teeth to determine and reconstruct is shown with.
  • the impression tray is fixed to the hardening of the impression mass by arbitrary finger pressure of the dentist or dental assistant on the jaw. It is especially important to keep the same position during this time, otherwise it would give a distorted negative impression, which would lead to a distorted dentition model. It is not natural for the user to keep the exact position during the impression taking.
  • the impression tray therefore has an impression layer.
  • the impression layer is a wax layer or wax-like layer which softens by gentle heating, preferably water, to allow the user to set the mark by biting before the impression is made. After filling the impression tray with the impression mass, the user can find the position after picking up the impression tray into the mouth by feeling with his teeth and "fix".
  • the impression tray is coated on the top and bottom with the impression layer.
  • the fixation of the position is secured by both the upper and lower jaw teeth row, since the impression or impression takes place with the mouth almost closed.
  • the annoying abandonment of the mouth can thus be dispensed with.
  • the choking of the user is not given due to the extent or the size of the impression tray.
  • the impression tray is designed as a single wall. Due to the single-walled design, it is easier to fill with the impression compound and to separate it out more easily. In addition, there is a more pleasant feeling during taking the impression.
  • the impression layers consist of wax or a waxy material.
  • the stop bar causes a retention for the impression mass and a uniform distribution of the impression mass, so that a uniform thickness of the impression mass can be obtained.
  • This bite bar defines the depth of penetration of the anterior teeth into the impression layers.
  • the impression tray may have a preferably removable handle.
  • the handle proves to be particularly helpful.
  • the user can find the middle of the lip and, on the other hand, it is advantageous for outsourcing.
  • the handle is removable.
  • a development of the invention is that a lid is provided.
  • the impression tray and the lid on a base with which the impression tray is vertically erected.
  • a base with which the impression tray is vertically erected for this purpose, for example, be provided that certain areas of the impression tray and the lid are flattened.
  • the stand makes it possible to incorporate the model compound into the vertically positioned impression tray closed with the lid and to carry out the curing of the denture model in a vertical position.
  • the impression tray can also be used as a storage box.
  • the invention also relates to a dental impression box for producing denture impressions, comprising:
  • At least one dental impression tray according to the invention, at least one impression mass and at least one model mass.
  • impression material is an alginate or a silicone.
  • Other impression materials may also be used which are known from the prior art.
  • a class 4 plaster is used for the model mass for making the denture model.
  • a denture model with very hard, smooth structure and very good detail reproduction can be obtained.
  • a 2-component plastic mixture is used for the model composition. Also you can get very good detail reproduction; However, the denture models produced from it have a glossy surface finish and are also more resistant to fracture than gypsum. However, it is also possible to use other known from the prior art model masses.
  • both the impression mass and the model mass may be colored with conventional dyes.
  • name labels or letter punches are conceivable.
  • the invention also provides a method for producing a denture impression with the following method steps: a) heating an impression tray having an impression layer for position marking above and below the receiving surface, and positioning the impression tray below or above the relevant denture part, b ) easy biting by the user in the impression layers to mark the correct position and removal of the impression tray from the mouth, c) curing the impression layers and filling the impression tray with an impression mass, reimporting the impression tray into the mouth and Positioning at the positions previously defined in the impression layers, until the impression material has hardened, d) removing the impression tray from the mouth, e) closing the impression tray with a lid and setting it up in the vertical direction, f) filling the interior with a model mass, g) Removal of the denture impression after hardening of the model mass.
  • the dental impression box according to the invention should preferably be provided for the user for his own use; However, it is also conceivable to extend the use of dental technicians and dental professionals.
  • the denture model produced with the impression box according to the invention, in particular with the impression tray according to the invention, can be regarded as a dental fingerprint.

Abstract

La présente invention concerne un porte-empreinte pour produire des empreintes dentaires, ce porte-empreinte présentant une surface de réception, ainsi qu'une boîte pour empreinte dentaire pour produire des empreintes dentaires et un procédé de production d'empreintes dentaires. L'objectif de l'invention est de fournir des moyens permettant à un patient ou à un utilisateur potentiel de réaliser seul son empreinte dentaire, sans connaissances particulières en technologie dentaire, de sorte que des éléments prothétiques dentaires puissent être facilement réalisés ultérieurement par des dentistes/prothésistes si nécessaire. À cet effet, le porte-empreinte selon l'invention présente au-dessus et au-dessous de la surface de réception une couche d'impression pour le marquage des positions. Ce porte-empreinte peut être utilisé également par un non-spécialiste en technologie ou médecine dentaires pour réaliser un modèle dentaire à n'importe quel endroit.
