Definitions
- the invention relates to a dental prosthesis production device according to the preamble of claim 1 , a dental prosthesis according to the preamble of claim 9 , and a method according to the preamble of claim 15 .
- dental prostheses are attached in the mouth of a patient with the help of an implant.
- the implant is typically provided with a so-called abutment after it has been inserted, which is connected to the implant in a geometrically true manner, for instance by configuring the surfaces of the implant and the abutment which face one another in an untrue or non-circular manner.
- the attachment itself is then carried out by means of an abutment screw which penetrates the abutment.
- an upper area of the abutment is configured as a tubing section whose internal diameter is sufficient for receiving the abutment screw.
- the abutment screw is supported slightly below this tubing section on a slightly conical supporting area in most cases, whose internal diameter is smaller than the diameter of the head of the abutment screw but wide enough to fit the shank and the thread of the abutment screw.
- the implant comprises an internal thread in a way known per se for threaded engagement with the thread of the abutment screw.
- the tubing section or the upper area of the abutment is slightly conical on the outside in most cases and fits into a corresponding recess in the dental structure in a geometrically true manner.
- the abutment flanges which extend radially towards the outside and which are intended to be in engagement with corresponding grooves in the dental structure in order to provide the desired anti-rotation device. If this area is sawed off without further ado, the anti-rotation mechanism is not available anymore; if, on the other hand, the abutment is used for abutment teeth of a bridge, the anti-rotation device which exists in this connection can be disturbing in some cases as in this case an angularly accurate orientation to, for instance, less than 1° would be necessary to avoid tensions.
- the invention is based on the task of providing a dental prosthesis production device according to the preamble of claim 1 , a dental prosthesis according to the preamble of claim 9 and a method according to the preamble of claim 15 which take account of the requirements presented to the dental prosthesis consisting of implant, abutment and dental structure in an improved manner and which make it possible to handle the production of the dental prosthesis by the dentist or dental technician in conformity with warranty claims.
- the production device itself comprises a selection device for abutments.
- the data of the dental structure produced by means of CAM, compression molding technology or rapid prototyping has been defined beforehand and is present in the production device, such that according to the invention it is particularly favorable that the load-carrying capacity of the power transmission surfaces between abutment and dental structure, the remaining wall thickness of the dental structure, the angular orientation, the height level, etc., can be defined beforehand and in a predetermined manner by the production device.
- a compression molding technology can also be used, and in this respect it is referred to the entire document EP 1 915 972 A1 by way of example.
- the abutments can be selected based on the existing dimensioning of the abutments and that the adjusted configuration of the bearing surfaces of the dental structure on the abutment can be specified for the CAM device.
- Shortening the abutment can be performed by means of a machining tool, in particular a milling cutter, or a CAM device.
- an inventively advantageous embodiment it is provided to provide a groove or a plurality of grooves which extend(s) vertically almost across the entire height of the upper area of the abutment which is referred to as tubing section herein.
- This embodiment comprising the anti-rotation device has the advantage that it is also effective in this respect if the height of the tubing section is reduced in accordance with the advantageous embodiment. Furthermore, by realizing flanges according to the groove and tongue principle in the radial inner surface of the dental structure the inventive anti-rotation device can be ensured with the desired reliability.
- the inventive dental prosthesis is configured as a bridge such that an additional anti-rotation device is not only undesirable but also disturbing the CAM device simply omits or does not produce the corresponding flanges such that the desired ability to rotate for a stress-free mounting of the bridge is given.
- the desired adhesive gap can be set at an exceptionally great accuracy of, for instance, 50 ⁇ .
- the milling process automatically defines the curves and radii as can be provided in a stress-related limited manner. An unintentional reduction and thus a decrease of the support surface are precluded, just like an unintentional confusion of the abutments which are adjusted to the corresponding dental structure, respectively. Finishing, such as roughening or the like, is not required; in fact, as part of the CAM production the abutment can, for instance, also be coated and thus be given a desired color in any suitable manner, wherein it is to be understood that the degree of roughness of the coating is adapted to the requirements.
- the upper area of the abutment can be shortened to standard dimensions in any suitable manner such that the inner surfaces of the dental structure can also be configured with standard dimensions.
- the configuration of the arrangement of grooves in the upper area of the implant can be used as an anti-rotation device but also, for instance, a respective untrue or non-circular configuration at a collar of the implant which is engaged with the dental structure.
- the desired shape of the dental prosthesis is determined based on an extraoral or intraoral 3D scan with the aid of a scanbody whose cylindrical geometry comprises a bevel or a ball-shaped reference surface in order to enable the determination and transfer of the initial situation (model) into 3D data (scan).
- the scanning result is supplied to a CAD device which, based on the shape of neighboring teeth of the desired dental prosthesis, forms a virtual shape of the restoration to be produced and divides it virtually into an implant, an abutment and a dental structure—optionally after the intervention of a user.
- an abutment refers to any desired meso-structure, that is to say any structure which extends between the implant and the dental structure which is also referred to as suprastructure, wherein it is to be understood that single-unit but also multi-unit dental abutment structures can be realized basically.
- the outer surface of the tubing section of the abutment can be provided with drain channels for adhesive in any desired manner which can be combined with anti-rotation elements, that is to say corresponding grooves or other female molds at the outer surface of the tubing section, if necessary.
- the realization of a chamfer at the transition between the tubing section and the collar of the abutment is particularly preferable. This chamfer is typically external to the contact area, that is to say to the area at which the abutment contacts the dental structure, and is thus subjected to lower surface pressure.
- excessive adhesive can be carried off in a suitable manner by means of a correspondingly suitable configuration of an elongated or ring-shaped recess.
- the collar of the abutment extends substantially vertically towards the outside and comprises a relatively small axial height which can amount to between 0.1 mm and 1 mm, 0.1 mm and 2 mm and between 0.1 mm and 0.5 mm. This enables an adjustment to the emergence profile in an anatomically favorable manner.

- FIG. 11 shows a schematic representation of an inventive dental prosthesis production device illustrating the part relevant for the invention, however, in a modified embodiment.
- FIG. 1 an abutment 10 is illustrated as part of a dental prosthesis which can be connected to an implant for the production of a dental structure (see FIG. 2 ).
- the abutment 10 comprises an implant connection 12 which is able to be supported in a torque-proof manner on an implant.
- the anti-rotation mechanism realized in this respect can be configured, for instance, with a hexagonal outer shape or a hexagonal inner shape.
- a collar 14 is formed above the implant connection 12 which collar merges into the implant connection 12 across a relatively large radius (see FIG. 2 ).
- the collar 14 tapers off in a relatively pointed manner and its top ends in an internal radius 16 which is even considerably smaller than the radius of the implant connection 12 .
- the tubing section 18 comprises a central recess 20 which is suitable for receiving an implant screw (see FIG. 8 ).
- the tubing section 18 comprises a slightly conical shape; the cone angle is, for instance, 3°.
- the abutment 10 comprises a plurality of grooves 22 which are evenly distributed around the periphery and which extend in an open manner towards the top and vertically across a chamfer in a closed manner towards the bottom.
- FIG. 2 It can be seen from FIG. 2 how a dental structure 28 can be connected to the tubing section 18 .
- an adhesive gap 30 extends between the dental structure 28 on the one hand and the collar 14 and the tubing section 18 on the other hand.
- the dental structure 28 comprises flanges which face inwards and which are intended to extend into the grooves 22 of the tubing section 18 in order to ensure that no rotation occurs.
- the implant can basically be provided with several lengths.
- the three different lengths presented herein only differ in the height of the tubing section 18 , while the shape of the implant does not exhibit any difference apart from that.
- the inventive selection device selects the appropriate shape depending on the size and shape of the dental structure 28 . Additionally, if necessary, it is possible to perform a fine adjustment by determining the exact desired height of the tubing section 18 by means of the CAD/CAM device ( FIG. 10 ).
- molars comprise dental material in the approximal or buccal/lingual direction.
- the shear forces introduced by the masticatory forces are correspondingly larger with molars, but due to the larger wall thickness in the area surrounding the tubing section 18 molars are also more stable such that a higher surface pressure in the tubing section 18 is possible.
- the depth of the grooves 22 amounts to approximately half of the wall thickness of the tubing section 18 , and it is to be understood that, if necessary, the selection device can also select an abutment for anterior teeth, which has a slightly smaller wall thickness, for instance 0.5 mm instead of 0.6 mm. In this way, the wall thickness of the dental structure can even be increased slightly.
- the selection device automatically selects a suitable abutment based on the result that has already been determined, that is to say the dental prosthesis to be produced, and that it adjusts this abutment optionally in a patient-specific manner, reduces its height or adjusts the rest of it.
- the shape of the abutment is compatible with that of the implant, as can be seen from FIG. 8 .
- the selection device selects an abutment whose height is the same or larger than a target height such that sufficient material is always provided for the machining process which may be required.
- the end radius 32 is attached or kept quasi automatically during machining or milling.
- the dental prosthesis production device also produces at least the inner structure of the dental structure 28 in a suitable manner and adapted to the result of the selection by the selection device and apart from that also adapted to the shape of each abutment 10 used for the production of the dental prosthesis.
- the outer shape of the dental structure 28 can already be determined based on a detection of the oral situation of the patient by means of a 3D scan, it is also possible and particularly favorable if the scanning result forms a virtual shape of the restoration to be produced based on the shape of neighboring teeth of the dental prosthesis to be produced and at the same time performs the division of this shape into implant, abutment and dental structure.
- the production device refers to an abutment library which has available a certain number of sizes of the abutment depending on the type of the dental prosthesis, wherein then, depending on the size, the production device takes into account the forces to be absorbed and the selection device selects the abutment also based on this.
- the height level of the occlusal surface of the dental structure is preferably taken into consideration that is to say that the abutment is shortened to such an extent or is selected in a shorter form by the selection device that sufficient dental material, such as ceramic material, is available between the upper end of the abutment and the occlusal surface.
- the groove 22 or the plurality of grooves 22 extends across a significant part of the height of the tubing section 18 of the abutment 10 .
- FIG. 3 illustrates an embodiment of an abutment 10 with only one groove 22 .
- FIG. 4 it extends to the collar 14 such that sufficient torque-active surface is still available even if the tubing section 18 has been shortened as greatly as possible.
- the flute (groove 22 ) comprises one end radius or one chamfer, respectively, in order to prevent abrupt changes in stiffness of the abutment.
- the wall thickness of the tubing section can be constant from the collar 14 to the end radius 32 , or can decrease slightly, for instance by 10% to 15%, wherein it is to be understood that the internal diameter of the tubing section 18 is constant across the height as in the recess 20 an implant screw with its head must be received.
- the abutment 10 comprises an internal taper 34 in the area of the collar or slightly above, and the head of the implant screw is in contact with the internal taper.
- FIG. 5 illustrates an embodiment which is modified even further.
- the anti-rotation device is realized by means of a groove 22 in the area of the collar 14 , while the tubing section 18 is free of grooves or flutes (grooves 22 ).
- FIG. 7 an abutment is shown slightly enlarged in a position screwed into the implant.
- the area between the collar 14 and the upper end of the implant 40 is smoothed in a way known per se with dental cement for providing a suitable emergence profile; due to the small height of the collar 14 an adaptation to the requirements of the patient is possible to a large extent.
- the transition towards the dental structure 28 is important which is in connection with the abutment 10 by means of the adhesive gap 30 .
- any desired suitable biocompatible adhesive or dental cement can be used as a filling material for the adhesive gap 30 .
- FIG. 8 It can be seen from FIG. 8 how an implant screw 42 can be inserted into the recess 20 .
- the screw head is, for instance, provided with an inbus structure which has been modified towards a TORX structure and the screw head 44 fills the recess 20 radially almost completely.
- the implant 40 is provided with an external thread known per se even if this is not shown in the Figures.
- an undercut 48 is formed which serves to receive adhesive which drains off. Furthermore, in this embodiment it is provided to compress the surface of the abutment after the shortening process which has been performed optionally, for instance by exposing it to a jet of a granular substance.
- FIG. 10 illustrates the schematic configuration of a dental prosthesis production device 62 .
- the oral situation of the patient, in particular the neighboring teeth of the dental prosthesis to be produced is scanned by means of a scanning device 60 .
- the scan data are present in the dental prosthesis production device 62 .
- the dental prosthesis production device 62 develops a dental prosthesis in a way known per se, for instance as a virtual hybrid between both the neighboring teeth or in any other suitable manner corresponding to the position of the dental prosthesis in the mouth of the patient.
- the dental prosthesis production device 62 defines the outer shape of the dental structure 28 , also including the height level for the provision of a suitable occlusal surface (or incisal surface) with respect to the antagonist of the dental prosthesis.
- the outer shape of the dental structure is also determined, also including the dimensions of the dental structure in the approximal and lingual/buccal direction.
- a selection device 66 selects a suitable abutment.
- the abutment 10 is selected such that its height fits the virtual internal space of the dental prosthesis, that is to say such that sufficient ceramic dental material is available for the support at the tubing section 18 .
- the wall thickness of the dental structure is taken into consideration as a marginal condition in the selection process, for instance >1 mm with anterior teeth and >2 mm with molars and pre-molars.
- the selection device 66 is part of a CAD station and determines the suitable abutment based on this, which can optionally be shortened in order to optimize it.
- a CAM device 68 serves this purpose and performs the shaping step which comes up in this respect and which in particular also shapes the end radius 32 of the abutment automatically.
- the selection device 66 also transmits shape data 72 for providing the internal shape of the dental structure 28 which is produced by the CAM device 68 .
- a test step it is further checked at the same time if the inner surface of the dental structure 28 fits the respective abutment 10 to be processed. This can be done either by adaptation—without adhesive—or by means of a scan for which the scanning device 60 can be used again.
- finishing is carried out in a finishing step again by means of the CAM device 28 .
- scan data is initially provided which has been produced by the 3D scanning device 60 .
- the selection device 66 does not only determine the shape of the abutment 10 but also the outer shape of the dental suprastructure 28 .
- This data which fits one another, also with regard to the height of the tubing section 18 in case of the abutment 10 , is supplied to the corresponding production devices, and the height of the abutment 10 is shortened to “L”, “M” or “S”, if necessary.
- the associated radius is rounded off at the same time.
- the internal structure of the dental structure 28 is determined such that it matches the radius and produced by means of CAD/CAM, and, of course, at the same time also the outer structure.
- the dental prosthesis is now assembled in a step 74 , wherein the dental structure 28 is adhesively bonded onto the abutment 10 .
- a test step and optionally in a finishing step 70 the result is reviewed and finishing is carried out, if necessary, for instance by removing occlusal defects at the occlusal plane of the produced molar of the dental structure 28 .
