Definitions
- Impression trays are used to keep the impression material in the area of the teeth to be molded. These consist of a base and at least two side walls, which together enclose the impression area, into which the impression material is introduced in order to be brought to the impression point, held by the tray.
- the walls one of which lies lingually / palatally and the other buccally of the teeth to be molded, should ensure that the mass cannot flow away, but is held to the side of the teeth to be molded. It is known (DE-A-196 08 546) to provide in the spoon a feed tube for the mass, which is provided with a row of outlet openings distributed over the length of the spoon.
- the teeth to be molded penetrate the impression material by closing the bit. This doesn't work if the patient bites on one of the two walls and consequently the teeth to be molded do not penetrate into the space between the walls.
- the mass is completely enclosed in a flexible hose, the hose material located between the mass and the teeth prevents a clean impression.
- the proposal of avoiding solid walls by the fact that the walls are formed by inflatable tube elements belongs to the not previously published prior art. Compressed air, water or impression material can be used to fill the hose elements.
- the impression material is not held securely due to the lack of dimensional stability of such impression trays and, for example, flows over the walls. The impression material will then not reach the desired height and the impression will not be taken completely.
- At least one of the walls comprises a rigid longitudinal rib.
- This longitudinal rib can form part of the wall, which, for example, is otherwise formed by a hose element to be filled or can be an insert of such a hose. It can also form the wall in question in its entirety.
- the stiffly constructed or equipped wall is preferably the lingual / palatal one. However, instead of this or in addition, the buccal can also be stiffly equipped.
- the bottom of the spoon is made of flexible material. Except for the
- the wall which is erected by filling comprises at least one hose element, the interior of which is connected to a filling opening.
- This filling opening can, for example, be connected to a dispensing device for impression material.
- the tube element is filled with the impression material and thus gets into the plump, sufficiently dimensionally stable state.
- the impression tray As soon as the impression tray has reached this state, its impression area can be provided with the required amount of the impression material in a conventional manner, for example by holding it under the nozzle of a suitable dispensing device. It is more advantageous according to the invention if the hose element to be filled with the impression material has at least one outflow opening directed towards the impression area of the tray. After the tube element has been filled, the impression material penetrates through this opening into the impression area of the tray and finally fills it. A number of such outflow openings is expediently distributed over the length of the impression region of the tray, so that a uniform filling results. If the hose element is arranged only on one side of the tray, it is provided with these outflow openings on its side facing the impression region.
- the hose element in the area of the stiff wall is returned towards the end of the spoon provided with the filling opening, the outflow openings are expediently arranged on the side of the stiff wall.
- the mass should find a certain resistance when it flows out of the hose element into the impression area of the tray, which ensures that there is a certain overpressure inside the hose element, at least during the filling process, which guarantees the plumpness and rigidity of the hose element.
- Slit-shaped outflow openings have proven successful, these preferably running in the transverse direction (based on the direction of the hose element).
- the outflow openings can form mouths or channels or sockets projecting into the impression area of the tray. On the one hand, this guarantees a particularly even filling of the impression area, on the other hand, it also creates the desired pressure difference.
- the outflow opening (s) with a burst seal, for example a burst membrane.
- the burst closure only opens when a predetermined excess pressure has been reached in the hose element, so that its plumpness is ensured in this way.
- Hose elements with blind ends should be provided with a special ventilation opening, which is expediently designed in such a way that it prevents the impression of impression material. This can happen, for example, in that the vent opening is very small or is provided with a corresponding valve.
- the filling opening is expediently designed to match the connection to an output device for impression material. If the
- Dispensing nozzle of this device ends conically, for example, a hose end forming the filling opening can be pushed onto the conical nozzle end.
- a form-fitting coupling for example with a bayonet lock and sealing surfaces, can also be provided.
- the impression material should be prevented from escaping from the filling opening while the tray is being handled. This can be achieved by a self-closing valve, for example analogous to the design of the filling valve of so-called valve bags.
- a special closure clip can also be provided, which is placed on the outside of the hose part forming the filling openings in order to pinch it together. Or a plug can be used. If it is connected to the hose part with sufficient dimensional stability, it can be provided with a handle according to the invention, on which the entire spoon can be handled.
- FIG. 1 is a perspective view of a first embodiment 2, a cross section through the first embodiment, FIG. 3 the perspective illustration of a second embodiment, FIG. 4 a cross section through the second embodiment and FIG. 5 a third embodiment
- the impression tray according to FIGS. 1 and 2 comprises a base 1, which can be formed, for example, by a flexible film or a piece of tissue.
- a base 1 On the lingual / palatal side, the plate 1 is delimited by a wall 2, which is formed by a rigid component. It is essentially plate-shaped. It forms a longitudinal rib stiffening the spoon. In this context, stiff is to be understood as a strength that enables this wall to maintain its shape sufficiently under the existing force relationships. Suitable materials are polyethylene, polyvinyl chloride, cardboard or the like.
- the boundary of the bottom 1 on the buccal side is formed by a tube element 3.
- the hose element 3 runs over the entire length of the bottom 1 and also encloses its rear edge 4. It ends after the wall part 2.
- the hose section 4 secures the lateral tensioning of the spoon between the wall 2 and the hose element 3 when the bottom 1 is too flexible to be able to perform this task.
- the hose element 3 is connected to a filling hose 5, the end 6 of which forms the filling opening.
- the hose 5 can be pushed with the opening 6 over the conical end of a filling nozzle.
- an opening 7 is provided, which points to the impression area of the tray formed by the base 1. It is either so small that no significant amounts of impression material come out and is only used for ventilation. Or it is so large that the impression material can flow out in the amount required for the impression and fill the impression area.
- the hose element 3 could also be provided with a plurality of discharge openings along its length, which point towards the top of the base 1 in order to feed the required amount of impression material evenly to the impression region.
- FIGS. 3 and 4 The embodiment according to FIGS. 3 and 4 is similar to that described above with regard to the bottom 1, the wall 2, the hose element 3 and the filling hose 5.
- a hose piece 4 also connects to the rear end of the hose element 3, which braces the rear narrow side the device.
- a hose element 8 which accompanies the inside of the wall 2 to the front end and has a plurality of outflow openings 7 which protrude into the impression area in the form of protruding mouths or supports and a uniform supply of this area with impression material enable.
- the filling hose 5, the hose element 3, the hose piece 4 and the hose element 8 can be produced in one piece, the different diameters being produced by different expansion.
- the projecting orifices 9 are extended in the form of channels 10 according to the previously described embodiment, which extend across the bottom 1 in a uniform distribution. They contain opening slots 11, of which the drawing indicates one per channel 10. It is understood that several such openings can be distributed over the surface of the bottom 1. In the case of a slot-shaped design of the opening 11, these are expediently arranged transversely to the longitudinal course of the channels containing them.
