Definitions
- the invention relates to a dental prosthetic arrangement.
- dentures are used to replace missing teeth of a Ge bite.
- Dental prosthetic arrangements are used that have a structure via a jaw implant anchored in the jawbone.
- a cohesive structure over several jaw implants can advantageously be provided.
- a dental prosthesis arrangement is known from US 2013/0171588 which comprises a filling channel and a ventilation channel in order to introduce a large amount of plastic for fastening the dental prosthesis.
- the arrangement of the channels is chosen so that the dentures are permanently attached.
- EP 3 040 047 A1 specifies a ring-fixed cap which comprises drainages through which saliva can leave the ring channel and the interior of the matrix.
- An anchorage for fastening a tooth replacement is known from WO 2008/040 134 A1.
- the anchoring comprises an anchoring part which can be attached to an implant and has a recess and a pivoting part which is pivotable with respect to the anchoring part. By attaching a hardenable substance in a recess of the anchoring part, the pivot part can be fixed in a specific pivot position.
- EP 1 224 920 A1 describes a dental implant-prosthetic system that ensures a permanent force-fit connection between the prosthetic abutment serving as a crown or bridge base and an implant and enables this connection, which is difficult to detach, to be easily released.
- the mounting part has a receiving bore in its base area into which a release pin can be inserted.
- the present invention is based on the object of specifying a partially removable dental prosthetic arrangement in which periodontal cleaning is possible and in addition a good seal to the implant can be achieved to reduce the entry of bacteria.
- a dental prosthetic arrangement for connecting at least one jaw implant to a structure is created, which are connected to one another via a lower part assigned to the jaw implant and an upper part assigned to the structure, with the lower part and the upper part forming at least in sections in the assembled state - nem cavity, which opens into an opening arranged on the side of the upper part, via which at least the cavity can be filled with a curable, liquid filling material, preferably made of plastic, so that after it has hardened, a holding force is created against the axial pulling off of the upper part from the lower part, the upper part can be removed from the lower part, destroying the cured filler material.
- a dental prosthetic arrangement is provided with a curable filler material between an upper part and a lower part, which after it has hardened the structure comes to rest on the jaw implants with a holding force that enables a wearer of the dental prosthetic arrangement to use it normally.
- the holding forces are large enough, for example, to keep the structure on the jaw implants during a chewing process.
- the wearer of the dental prosthetic arrangement can thus use his prosthetic restoration, such as a fixed tooth replacement.
- a simple yet reliable possibility is provided to create conditionally removable dentures.
- the filling material fills the cavity between the upper part and the lower part essentially completely.
- the cavity is filled with the filling material after filling, so as not to form pockets or the like that are the starting point for germs. could.
- the term “essential” is understood here to mean that smaller inclusions can be present in the filler material without this being understood as a deviation from the basic inventive concept.
- sections of the cavity are provided to form the holding force between the upper part and the lower part.
- further sections for sealing can be provided between the upper part and the lower part.
- the filling material fulfills two different functions, which include both the provision of a holding force to prevent the upper part from being pulled off axially from the lower part as well as the sealing towards the jaw implant, so that in particular the entry of germs into the area of the jaw implants by bacteria or the like is reduced, which in particular can prevent further deterioration of the oral situation due to peri-implantitis. Since the initially liquid filling material is fed from the cavity into the occlusal connection in the direction of the jaw implant, it is possible to fill the cavities that would otherwise exist there.
- the cavity can have different geometric shapes.
- the cavity can use the available space in the upper part and lower part so that the filling material can be formed with the desired holding force.
- simple geometrical basic shapes such as annular grooves or the like, more complex designs are also conceivable.
- Individual sections, for example in the form of radially aligned segments, can be designed to form the holding force, while, for example, an annular further section for sealing could be present.
- a ventilation channel is provided in the upper part.
- a rotation lock is formed between the upper part and the lower part.
- the area above and below the cavity between the upper part and the lower part is formed by corresponding bearing surfaces in such a way that the upper part comes to rest on the lower part without greater mechanical clearance, in particular in the radial direction.
- a non-rotationally symmetrical design of the bearing surfaces therefore does not allow any rotation of the upper part. This can be particularly advantageous in the case of a single tooth restoration in the form of a tooth crown.
- the filling material can be produced from a plastic material with a predetermined hardness, provision being made in particular to use silicone material for the filling material.
- adhesive plastics which are known per se in dental technology, can also be used.
- a corresponding hardener can be added here so that the holding force in the cavity has the desired value after hardening.
- Hardeners for plastic or silicone materials are known. These include, for example, the addition of silica or the use of silanized quartz powder. In general, however, it would also be possible to silanize other inorganic or mineral materials and use them as fillers. It would also be conceivable to use fillers containing silicon, for example.
- the opening arranged on the side of the upper part can be closed again.
- the opening can be closed, for example, with a grub screw or the like.
- the opening arranged laterally on the upper part advantageously has an internal thread into which the grub screw or another suitable sealing plug can be introduced.
- it can be particularly advantageous to design the laterally arranged opening together with the possibly present internal thread so that it can be coupled to a pressing device for supplying the liquid filler material.
- a suitable cartridge or the like to the side opening, which a practitioner, such. B. allow a dentist or a dentist the metered addition of liquid filling material.
- a tool attachment is provided for releasing the upper part from the lower part.
- a depression in the form of corresponding grooves can be formed between the upper part and the lower part, so that a corresponding tool can be used to solve the upper part while overcoming the mechanical stability of the filling material in the cavity, so that the filling material breaks in the cavity or is destroyed.
- the dental prosthetic arrangement according to the invention can be used in many different oral situations, in particular the use of several jaw implants and the provision of one dental prosthesis can be advantageously implemented in order to create partially removable dentures.
- a restoration for a single implant with a crown is also possible.
- Fig. 2 is a partially sectioned side view of a further Aust approximate shape
- a dental prosthetic order 2 is shown in a perspective side view, which consists of several parts, as he will be explained below.
- a connecting element 4 is provided, which has a receptacle 6 on its lower part, which can be inserted into a jaw implant (not shown in FIG. 1).
- An external thread 8 which is angled for receiving makes it possible to place an abutment portion 10 on the external thread 8, the abutment 10 having a corresponding opening or internal thread on its underside 12 for this purpose.
- abutment 10 and connecting element 4 are also referred to as lower part 14.
- the two-part construction of the lower part 14 shown here which is also angled with respect to a direction of insertion into a jaw implant by means of the receptacle 6, is only to be understood as an example. It is known to the person skilled in the art that a lower part 14 can also, for example, be formed in one piece or can also be formed without angulation.
- the un- Part 14 be integrated into the jaw implant or an abutment portion of the jaw implant.
- the lower part 14 has in its interior a continuous occlusal channel 16 which penetrates both the abutment 10 and the connec tion element 4.
- a corresponding upper part 18 is placed on the lower part 14, with corresponding bearing surfaces 20 and 20 'being formed between the abutment 10 and the upper part 18 so that the upper part 18 can be placed on the lower part 14 without having radial play.
- the corresponding inner surfaces 20 and outer surfaces 20 'each have an annular groove 22 and 22', which complement the upper part 18 and the lower part 14 after assembly to form a cavity.
- the corresponding inner surfaces 20 or outer surfaces 20 ' are shown rotationally symmetrical in FIG. 1, but can also be formed between the upper part 18 and the lower part 14 with an anti-rotation device (not shown in FIG. 1).
- the upper part 18 can be connected to a crown or a prosthesis in later manufacturing steps, in which case several upper parts 18 and lower parts 14 can also be part of the dental prosthetic arrangement.
- the embodiment with an annular groove 22 or 22 'on the upper part 18 or lower part 14 as a cavity is only to be understood as an example.
- any shapes come into consideration here, for example with an undercut in relation to the insertion direction in the upper part 18 and lower part 14, which can also be slightly offset from one another.
- the partial overlap only has to ensure that the filling material bridges the cavity between the upper part 18 and the lower part 14.
- the cavity does not necessarily have to be designed to be circumferential.
- the cavity can have different geometric shapes.
- the cavity can make use of the space available in the upper part 18 and lower part 14, in addition to simple basic geometric shapes, such as annular grooves or the like, also more complex Ausgestaltun conditions being conceivable.
- individual sections for example in the form of radially aligned segments, can be designed to form the holding force, while a circumferential section effects a seal between the upper part 18 and the lower part 14.
- Access is created to the cavity, which is connected via an opening 24 arranged on the side.
- the laterally arranged opening 24 can be provided with an internal thread 26.
- a screw 28 can be used, which closes the channel 16 to the jaw implant. This can for example, as shown in Figure 1, be designed as a hexagon socket screw.
- FIG. 2 the dental prosthetic arrangement 2 according to FIG. 1 is shown in an assembled state in a sectional view. It can be seen that the annular groove 22 of the upper part 18 and the annular groove 22 ′ of the lower part 14 complement each other to form the cavity 30 already mentioned. It can also be seen in FIG. 2 that the cavity 30 can be reached via the lateral opening 24. Consequently, it is possible to fill the cavity 30, which surrounds the abutment 10 and the upper part 18 along the entire outer circumference, via the opening 24 attached to the side with a liquid plastic material.
- the filling of the cavity 30 with a liquid plastic material is explained in more detail with reference to FIG. You can see that the liquid Filling material made of plastic, which is shown ver in Figure 3 with the reference numeral 32, completely fills the flea space 30, which is designed as an annular channel in this example. After filling with the liquid filling material 32, the opening 24 can be closed with a sealing plug 34.
- the filling material 32 can generally be formed from plastic, with a silicone material in particular also being possible.
- the holding force which has to be applied to pull the upper part 18 from the lower part 14 while wearing a prosthesis provided with the dental prosthetic arrangement 2 is set by the hardness of the filling material 32.
- the addition of silica in silicone material can also be considered in order to be able to achieve the desired degree of hardness.
- the releasability of the upper part 18 and lower part 14 could be achieved by destroying the filling material 32 by using a fine-flowing plastic or zinc oxide (eugenol).
- a fine-flowing plastic or zinc oxide eugenol
- other hardenable inorganic materials could also be suitable.
- a material would also be possible that receives flowable properties due to the influence of ultrasonic vibration in order to be able to detach the upper part 18 from the lower part 14 again.
- a ventilation duct (not shown in the figures) can be provided, which leads to the outside the air located in the cavities before the filling material 32 is introduced. It is also possible To remove dentures that destroy the filler material 32 sensitive to the annular channel 30, provide a corresponding tool kit in order to be able to apply high enough forces to separate the upper part 18 from the lower part 14.
- the dental prosthetic arrangement 2 is advantageously used in the case of a structure in the form of a dental prosthesis with several jaw implants or a tooth crown with one jaw implant.
- a partially removable denture can be created in a simple manner, which also provides a seal with respect to the jaw implants in order to reduce or completely prevent further infestation by bacteria or the like.
- the dental health in a patient's mouth is significantly improved even when wearing a dental prosthesis.
