Description

Dental model

The invention relates to a dental model,

consisting of a generatively manufactured model of a dentate or edentulous maxilla and mandible.

The invention relates to such a dental model, which is used as a work and control model for the production of dental prostheses or for the production of patient-specific

Orthodontic appliances can be used. The prior art is on the

DE 10 2007 014 088 A 1. There, a method for the generative production of individual dental moldings is explained. Furthermore there is an articulator system

described, which allows the individual accurate adjustment.

Based on this prior art, the present invention seeks to provide a dental model, which the dental technician

Building facilitates and the individual

Production of individual elements and their exact incorporation into the model allows.

To solve this problem, it is proposed that the model of at least one, at least partially segmented sprocket with

Single-tooth models or groups of teeth models as well as an individually shaped base plate

CONFIRMATION COPY exists that the base plate coded

Slots and has the single-tooth models or groups of teeth models to the coded

Slots complementary plug-in means

have, so that these parts are unmistakably connected to each other detachable or connectable.

According to this embodiment, the

Single tooth model or groups of teeth models individually removed from the model and incorporated back into the model, with a

unmistakable assignment and arrangement is ensured by the corresponding coding of slots and plug-in means.

An alternative solution is thereby

characterized in that the model of at least one, at least partially segmented

Sprocket with single-tooth models or

Tooth group models and an individually shaped base plate is that the

Ring gear on side surfaces of it

trained tooth models or

Tooth group models approximately parallel to

Base plate extending recesses or coded recesses, in the appropriate components of single-tooth models or

Tooth group models can be inserted, which can be positioned between the side surfaces. Again, it is possible to remove single-tooth models or groups of teeth models from the model to perform appropriate work and then incorporate these components back into the model, with a confusion-free and correct position arrangement of the parts after the

Inclusion is ensured. The

corresponding recesses and matching

Components of interconnectable parts can have different shape design

have, so that by this shape design also an encoding is achieved, so that the respective dissolved part can be incorporated only at a certain place in the model again, so that a positionally correct arrangement and alignment is ensured.

It is preferably provided that the

Single tooth models or tooth group models as plug-in means have a mutually differently profiled underside and the

coded slots complementary to it

Have recesses or form. It is particularly preferred that the single-tooth models or groups of teeth models

Form hollow body whose slots facing the slots with their peripheral edge forms the complementary plug-in means, and that the base plate to matching channel contours

has, in which engage the marginal edges in the inserted position. Although such single-tooth models or

Tooth group models also as assivkörper

be formed, however, the production as a hollow body is cost-saving both in terms of material and in terms of

Production time. Due to the design of these single-tooth models or dental group models as a hollow body, it is possible to use their marginal edges as plug-in means, wherein the marginal edges of each single-tooth model or each

Tooth group model are designed differently to other single-tooth models or tooth group models, so that a confusion-free assignment to the corresponding slot is achieved. The slots can also only as

Be formed gutter contour, in which the

Edge edges of the hollow body can be used. Particular preference is further provided that the base plate on its side facing away from the slots or tooth models a side

individual, patient-specific

Articulated molded part which is coupled to the base plate or formed integrally therewith, which for coupling to a Artikulatorplatte a

Articulator system is determined. It can also be preferred that the

Base plate has another coded slot in which an oral model insertable or is releasably inserted, which is essentially the palate or lower jawbone floor of the

Patient images. Furthermore, it can preferably be provided that the base plate has a further coded slot into which a vestibular model is insertably or releasably inserted, which images the fold and ribbon, which are located between the alveolar ridge and cheek and lips of the patient.

It can also be provided that a jaw, namely upper jaw or lower jaw, with a base plate and single-tooth models or

Tooth group models is modeled and the other jaw, namely lower jaw or

Upper jaw, with an antagonist model

is modeled.

It can be provided that the

Antagonist model on its side facing away from the tooth models an individual,

Having patient-specific articulator molding, which is coupled to the model or integrally formed therewith, and which is intended for coupling to a further Artikulatorplatte an articulator system. To enable the simple removal of single-tooth models or groups of teeth models, it can be provided that the single-tooth model or the tooth group model has a recess as

Has tool engagement and / or the

Base plate in the range of at least one

Slot a breakthrough as

Tool penetration has.

Preferably, therefore, consists of

Dental model according to the invention of hollow or solid manufactured single-tooth models or

Tooth group models with profiled underside and a correspondingly negatively profiled baseboard, which can be made up or in particular individually according to the

Recording data of the patient is made. On this base plug one or more segments of the dental model can be plugged, with a unique arrangement

is ensured. In addition, there is the

Base plug from a separately adaptable or integrated patient-specific

Articulated molding, which allows the coupling to an articulator of articulator systems, as described for example in DE 10 2007 014 088 A 1.

Artikulatorformteile this type can also be integrated into the antagonist model, so this also with a

Artulatorplatte an articulator system can be connected or coupled. The invention is explained in more detail with reference to the embodiments shown in the drawing.

In the drawings, a dental model is shown, which consists of a generatively manufactured model of a dentate or edentulous maxilla and mandible.

As shown in Figure 1, the model consists of a segmented sprocket with segments la to lk, these segments either

Single-tooth models or groups of teeth models can represent. In addition, one is

Base plate 3a is provided, which is shaped individually according to patient data. As can be seen in particular in FIG. 5, the base plate 3a has coded slots 3.1 to 3.11, while the single tooth models or tooth group models la to lk have complementary plug-in means to the coded slots 3.1 to 3.11, so that these parts are unmistakably connected or connectable to one another unmistakably. to

Machining can therefore be the dental technician or the like each one of the models la to lk remove, edit and again with the

Merge base plate 3a correctly.

In the embodiment of Figure 9, the dental model 1 consists of a sprocket element with components 2.10 and 2.11 and a

Sprocket segment 2, which is releasably secured by being in its side surfaces

correspondingly coded recesses or

Having projections that correspond to

Projections or recesses of the parts 2.10 or 2.11 fit, so that a

Integration and outsourcing in a simple manner is possible. The possibility of displacement is thereby in the direction of a vertical

penetrating axis x given.

In the embodiment of Figure 1 to Figure 8, the single-tooth models or

Tooth group models la to lk as plug-in means a mutually differently profiled underside, in each case in Figure 1

upper side of the corresponding segment is visible as a peripheral edge. The coded

Slots 3.1 to 3.11 point to this

complementary recesses, so that a clear integration is possible. In the exemplary embodiment, the single-tooth models or groups of tooth models la to lk are designed as hollow bodies, whose openings 3.1 to 3.11 in the desired position face opening with their Edge edge forms the complementary plug-in means, wherein the base plate 3a matching

Has channel contours, in which the

Edge edges fit in the inserted position.

The base plate 3a also has on its side facing away from the slots or tooth models an individual patient-specific

Articulator molding 3b, which can either be coupled to the base plate 3a or can also be integrally formed therewith. This articulator molding is used for

Coupling to an articulator plate of an articulator system.

As can be seen in particular from FIG. 5, the base plate 3a has a further coded slot 3.12 into which an oral model 2a can be inserted, so that it can be arranged suitably and unambiguously. This oral model 2a essentially forms the palate or

Lower jaw of the patient and is made individually according to patient dimensions. The base plate 3a additionally has further coded slots 3.13, in which a vestibular model 2b is exact and accurate

can be incorporated. Such

Vestibular model depicts the graft fold and ligaments that are located between the alveolar ridge and cheek, as well as the patient's lips. As can be seen in particular in Figure 2, for example, a jaw, namely the

Upper jaw affiliated with a base plate 3a to a Artikulatorplatte 4a, wherein

between articulator 4a and base plate 3a a Artikulatorformteil 3b is inserted. On the base plate 3a, a vestibular model 2b and the segments la to lk is inserted. The lower jaw is equipped with an antagonist model 5, which shows an articulator molding part 4a and an articulator plate 4b.

As illustrated in FIG. 8, the respective single-tooth model or group of teeth models, here the model 1b, can have a recess 6 or a recess 7 for a tool engagement. The recess 7 is suitable for manual access, while the formed as a through-hole recess 6 serves a

Tool, for example, to insert a pin from the bottom to the segment of the

To solve base plate 3a. In this

Embodiment is the segment lb

several parts. It consists of a tooth stump lb.l, a gum part lb.2 and a

Tooth part lb.3. The advantage of this embodiment is that the sprocket element can be used for the production of dental prosthesis with a decrease of the gum part without gum part. The embodiment of the invention provides a segmented dental model available, which modular by the attachment of

Segments can be used as a full model or saw-cut model.

To produce dental restorations, for example, two different types of dental models have hitherto been manufactured. For the production of soft tissue restorations, such as full dentures, full models are used, which include the hard substance, which also reflects the soft tissue of the jaw, for example, the palate and the folds. to

Production of hard tissue stored

Restorations, such as crowns and bridges, use saw-cut models that merely depict the alveolar ridge with the teeth on it.

In the manufacture of complex restorations, such as so-called

Combination work, which usually consists of a hard and soft tissue-mounted dental

In order to make the restoration, it is necessary to produce both a full model and a saw-cut model, since the required operations can not be performed on a single model. By using two models but would increase production costs and the

Making the dentures would be difficult since the restoration can be designed and adapted on both models.

When working on two models, it could also come to transmission errors, which can be noticeable by precision deviations.

By the invention, it is possible by the modular Umsteckcken the model segments, the

Manufacture of combination work on one and the same model, so that lower production costs and the risk of transmission errors in the manufacture of dentures counteracted with the model.

The dental model system according to the invention consists of a segmented sprocket la to lk, with which it is possible, for example, to remove individual teeth and an oral model 2a, which essentially the palate or

Mandible Mouth Bottom Mounts and One

Vestibular model 2b, which depicts the fold and ligaments that move between the alveolar ridge and the cheek or lip. All designated parts can be removed in particular and unmistakably adapted to an individually shaped base plug plate 3a by the special profiling, which results, for example, by the hollowing of the segments. The special profiling and use of an individual Patient-specific manufactured base plate 3a has the advantage that the segments and the base plug can be gracefully designed so that easy handling in the

Manufacture of dentures can be achieved with this model.

In addition, the base plug 3a can be equipped with an articulator molding 3b, which coupling the model to a

Articulator 4a allows an articulator system.

The articulator molding 3b is based on biometric

Patient data generated design element, which is the skull to the skull positionally correct adaptation of dental models in a

Articulator system allows.

CAD software turns digital

Dental models using biometric patient data virtually articulated, that is, the upper and lower jaw becomes the

Skull positioned in the correct position in a virtual articulator. Using the consequent design conditions, an articulator molding described above can be constructed which can be used as an adapter between the sub-model and the articulator plate. The invention is not on the

Embodiments limited, but in the context of the disclosure often variable. All new, disclosed in the description and / or drawing single and

Combination features are called

considered essential to the invention.
