Definitions

  • the present invention deals, as its name implies, with dental models commonly used in implant rehabilitations, as well as with a method of manufacturing said dental models so that errors produced by human intervention are minimized at the same time. that a significant reduction is achieved, both in terms of time and materials.
  • the method of the present invention is based on, from the information of a patient's mouth, obtaining a precision dental model of said mouth in one piece.
  • a second phase of sampling and measurement of both the patient's mouth and the implants placed in the patient's mouth intended to receive the prostheses A third phase in which, from the data obtained in the previous phase, a dental model or replica of the patient's mouth is developed and which in turn comprises:
  • the second and third are of special relevance, since the manufacturing of the prosthesis and its subsequent adaptation to the patient's mouth will depend on them. Obviously, the evolution of said implant in the patient's mouth, its adaptation and functionality will depend largely on the design of said prosthesis and, therefore, on the manufacturing stage thereof.
  • a manual impression takes a fairly high risk of falsification due, for example, to the deformations produced in the "transfers" when removing it, which may cause the subsequent placement of the implant replica to not correspond to the actual position of the implant. mouth.
  • this technique which consists of two separate pieces and two different materials, consists of a process that entails a higher economic and time cost.
  • Both the dental models and the manufacturing process of said dental models set forth in the invention described below solves the aforementioned drawbacks by eliminating the errors of the impression, setting, etc. described above and increasing the accuracy and speed of the process, so that physical precision models are achieved that accurately reproduce the patient's mouth, simplifying the process and saving on costs and time.
  • the dental models of the invention are characterized by being a single piece that replicates with great precision both the geometry of the mouth and that of the implants placed, avoiding obtaining two differentiated pieces, on the one hand the model and on the other the Implant analog that must be mechanically joined later.
  • the manufacturing process of said dental models of the invention basically comprises, as a first step, obtaining information about the patient's mouth that allows said mouth to be faithfully reproduced, that is, both the geometry of the mouth itself and the one of the dental pieces and the implants that can have placed. From that information, the complete dental model of the patient will be manufactured in one piece by means of any of the known techniques.
  • Figure 1 Shows a perspective view of a dental model obtained by the method of the invention and where both dental pieces and implants that have been placed are appreciated.

  • That information about the patient's mouth is essential to be as accurate as possible, not only in terms of the shape of the patient's mouth, that is, the dental pieces that will surround the prosthesis, but also, of course, the implant. , especially in cases where it is of the screwed type, since the degree of precision required is much greater than in those where the union with the prosthesis is caused by cementation.
  • said implant may comprise a reference element that, by means of marks or other types of elements, is capable of giving to the system all the precise information so that both its morphology and its location in the space is perfectly defined and a replica of it can be subsequently made on the mold that corresponds to the reality of the patient's mouth.
  • this information is available in the form of one or several files, for example of the type called "STL" to, from them, obtain the physical dental model using any of the known techniques, such as the so-called rapid prototyping or laser sintering such as for example 2,3,4 or 5 grade laser machines, jack, C0 2 , or heat laser machines, etc. or combinations of them.
