Abstract
A device for making, duplicating and fixing dental models in articulator, using dental replicas (19) of plaster or other material with bases (20) for the manufacture of dental models (18). The device incorporates at least three pins (3) that have elements to be embedded in the bases (20) in charge of said pins (3) for positioning and fixing the dental models (18) to platens (7) that have a minimum of three protruding protrusions (8) on its surface and arranged to fit with the pins (3) and, where appropriate, provide a releasable connection with the pins (3). The platens (7) are attached to the articulator (1) with a height or ratio (h) between protrusions (8) of the platens (7), upper and lower, preset and reproducible.

A dentistry device for making, duplicating and fixing dental models to an articulator, the dentistry device comprising:
- two platens, each platen having at least three fixing elements protruding from a surface of the platen;
- at least three pins, each of the pins having a fixing means to fix the pins to a base of a dental model, each of the pins further comprising a protrusion or lower cavity and, each of the fixing elements having a complementary protrusion or lower cavity configured to mate with the protrusion or lower cavity of a corresponding one of the pins;
- a tray made of an elastic material, the tray configured as a mold for making the base for a dental model, the tray is a container having a bottom with a plurality of holes, the fixing elements of the platen are capable of fitting in the plurality of holes from below and the pins are capable of being fixedly placed from above in the plurality of holes by the fixing element so that the plurality of holes are plugged;
- an articulator comprising two arms, each arm having a stop, the stops configured to stop movement of the articulator at a maximum closure position of the articulator, each arm further comprising a base surface configured to receive one of the platens, in the maximum closure position, the base surfaces are held in a position parallel to one another thus maintaining a predefined separation between end surfaces of the fixing elements when the platens are positioned on the base surfaces of the articulator;
- a double positioner that is attachable to the articulator, the double positioner comprising a hollow body in which a dental replica to make the dental model is arrangeable and adjusted to reproduce a patient's bite;
- a platen positioner that is attachable to the articulator, the platen positioner comprising two opposite end surfaces parallel to each other, the end surface are in a shape of a geometric figure with a minimum of three vertices, each end surface having a fixing and/or positioning element arranged in each of the vertices and configured to mate with the fixing elements of the platens when the platen positioner is attached to the articulator;
- the dental device is configured to establish a detachable connection between a dental model in a pre-established and reproducible relationship.
A dentistry device for making dental models from dental replicas, duplicating the dental models and fixing the dental models to an articulator to accurately reproduce a patient's bite, the dentistry device comprising:
- two platens, each platen having at least three fixing elements protruding from a surface of the platen;
- at least three pins, each of the pins having a fixing means at one end thereof to fix the pins to a base of a dental model, each of the pins further comprising a protrusion or lower cavity at an opposite end thereof and, each of the fixing elements having a protrusion or lower cavity at an end thereof that is configured to mate with the protrusion or lower cavity of a respective one of the pins;
- a tray made of an elastic material, the tray configured as a mold for making the base of the dental model, the tray is a container having a bottom with a plurality of holes, the fixing elements of the platen are capable of fitting in the plurality of holes and the pins are capable of being fixedly placed in the plurality of holes by the fixing element so that the plurality of holes are plugged;
- an articulator comprising two arms, the arms having a stop that stops movement of the arms relative to each other at a maximum closure position of the articulator, each of the arms further comprising a base surface configured to receive one of the platens, in the maximum closure position, the base surfaces are held in a position parallel to one another thus maintaining a predefined separation between the ends of the fixing elements when the platens are positioned on the base surfaces of the arms of the articulator;
- a double positioner that is attachable to the articulator, the double positioner comprising a hollow body in which a dental replica to make the dental model is arrangeable and adjusted to reproduce the patient's bite;
- a platen positioner that is attachable to the articulator, the platen positioner comprising two opposite end surfaces, each of the end surfaces of the platen positioner is in a shape of a geometric figure with a minimum of three vertices, each of the end surfaces has a fixing and/or positioning element arranged in each of the vertices and configured to mate with the fixing elements of the platens when the platen positioner is attached to the articulator;
- the dental device is configured to establish a detachable connection between a dental model in a pre-established and reproducible relationship.
