Superstructure attachment method; A method of aligning a drilling device using a drilling jig to form an artificial tooth hole in a human jawbone; And a method for implanting the superstructure prefabricated in an artificial tooth root fixed to a man's jawbone.

It is known to implant artificial roots in the jawbone of a person without teeth. In order to permanently fix the artificial root, a number of factors must be met, among other things with regard to material selection and manipulation techniques. In fact, artificial roots made of pure titanium with a surface with fine depressions developed by Professor Branemark show very good long-term fixation properties. Screw-shaped prostheses are implanted into the jawbone that heales and heals, typically for several months, over a period of time. Thereafter, a tooth may be installed in the artificial tooth root. Most implanted elements are provided with external screws, so they are implanted screws and are attached by screwing them into holes formed in the bone tissue. Typically, these holes are preformed with screws, but it is also possible to form screws in self tapping screws. Typically, implanted elements require shorter or longer time for healing before they are exposed to significant load. For implanted elements, it is possible to attach individual teeth, such as one tooth per element, but also a point of attachment for a bridge structure in which a number of implanted elements, such as at least two or more comprise several teeth or complete tooth rows. Used as For this purpose, a suitable design for the free end of the implanted element may comprise an internal thread of the cylindrical bore in the tooth element which engages with an external thread on the cylindrical attachment part of the single tooth prosthesis.

Simple bridge structures that are attached to two or more implanted elements are known from SE-448 599 (Patent Application No. 8503580-6). This bridge structure is inherently coupled with a rigid bridge foundation, which is directly attached to the titanium element by screws and mounting devices for removably attaching a row of teeth on the bridge foundation. Advantages of the rigid bridge foundation include that the tooth rows can be attached in a simple manner and the bridge foundation can be easily manufactured. However, the known device must be attached in the jawbone with the spacer parts precisely parallel so that it is possible to install the bridge foundation undeformed, instead of allowing it to proceed individually to the position of the free end of the spacer part, their free ends being The disadvantage is that it must lie on a predetermined plane and be spaced apart by a predetermined distance.

Perhaps it is not possible to achieve this accuracy in normal cases, so it is necessary to apply the bridge foundation individually to the spacer. This application is realized for example by means of columnar spacer portions provided between the respective implanted elements and bridge structures described in Swedish publication 446 370. Both ends of the spacer portion are tapered conically. The free end is provided with a threaded bore that allows it to be screwed into a fitting hole of the dental prosthesis. Between the dental prosthesis and the conical free end is provided a device consisting of a sleeved component with conical inner and outer shell surfaces. This known device has some flexibility, but the above specification requires the effect of the columnar element location, and possible necessary adjustments between the conical surface of the bridge and the sleeved part can be made before final installation.

These disadvantages can to some extent be overcome by an apparatus for attaching a tooth bridge according to Swedish patent application 8800082-3. Here, the spacer portion has a conical free end, and the bearing bridge structure engages with a sleeve designed to have a conical bore used to install the conical end of the spacer portion, each sleeve having two side vanes. Adjacent vanes on adjacent sleeves overlap one another and they are joined by screws. However, the design or construction of such a device is not optimal in terms of hygiene, strength and simplicity of installation in a series of teeth.

The installation of the tooth bridges requires an enormous amount of work, as a result of which the cost of rebuilding the entire maxilla or mandible is relatively high. In addition, reconstruction makes the patient spend a lot of time. Therefore, with user-friendly implants and installation schemes, it is desirable to reduce the amount of time and work required for full jaw reconstruction, including reconstructions involving only critical adjacent portions of the dentition.

In Swedish patent 501 174 a dental prosthesis device is known in which the tooth bridge is attached to the artificial root by means of fitting agents aligned between the respective tooth root and the anchoring device of the tooth bridge. This fitting material precisely engages the spacer portion of each artificial tooth, and they also engage each fixation device on the tooth bridge with a predetermined clearance. The bridge may be attached to the fitting member by an adhesive layer or a hardening layer applied to the clearance, and the fitting member may be removably attached to each spacer portion.

In Swedish Patent No. 500 851 a dental prosthesis device is known in which the bridge base is fixed to an artificial tooth root attached to a man's jawbone. The artificial tooth root is attached in four holes drilled in the jaw bone using a jig. The bridge foundation may be supplied as a prefabricated element selected from a set of existing bridge foundations.

When using tooth bridges that require little or no treatment for application to artificial tooth implants implanted in the human jawbone, techniques based on introductory adjustment or preparation for application to the bridge attachment were used and also to achieve the required accuracy. In an attempt was used a technique in which a drilling jig was used. The latter case requires strict conditions on how the drilling jig or other positioning device should be applied and handled when the hole for the artificial tooth is drilled.

In this technical context, the present invention provides a dental prosthesis device and a component for the dental prosthesis device that enable the use of a prefabricated superstructure with minimal risk of misalignment, thereby minimizing the need for individual application of the superstructure when attached to the patient. It aims to provide.

According to the invention, this object comprises a reference device used in accordance with the features of claim 1, ie for installing a positioning device, the reference device defining a definite position in relation to a person's jawbone, A dental prosthesis device comprising a drilling jig and an artificial tooth guide insert, which can be installed in the drilling jig, according to the features of claim 21, ie comprising a drilling jig, said drilling jig There is provided an alignment device which is arranged to align the drilling jig to a predetermined position in combination with a reference device implanted in the man's jawbone, the drilling jig for guiding the drill bit to make a fixing hole in the man's jawbone. A guide device is provided, through a positioning device, wherein the feature of claim 27 is provided. The drill guide insert according to claim 31, comprising a fitting device used to fit with the drill guide insert in a limited position, ie in relation to the drill jig, and a drill bit through hole. Thus, i.e., through the artificial root guide insert, characterized in that it comprises a fitting device used to insert the artificial root guide insert in a restricted position in relation to a jig and comprises an artificial root through hole. Depending on the part, i.e., the artificial tooth holder device, the instrument penetrating device, the alignment determination device arranged to be guided by the first guide surface positioned by the jig, and also the alignment guided by the second guide surface located by the jig The artificial root alignment device comprising a depth determination device, comprising: According to the features, ie, the first fixation device comprises a plurality of attachment elements with predetermined positions determined by the manner in which the positioning device fits the reference device, And in accordance with claim 30, ie with a drill guide through-hole characterized in that it has a drill bit through-hole having a diameter different from the corresponding diameter of the other drill guide insert included in the set.

It is furthermore an object of the present invention to fit in position in accordance with the features of claim 39, i.e. using a reference device that defines the position adjusting means in a restricted position with respect to the man's jawbone, and the superstructure is adjusted. A method, characterized in that it is provided as a prefabricated element in a prefabricated attachment unit having a predetermined position with respect to the device, in accordance with the features of claim 40, i. By means of positioning the drilling jig using a reference device defining a and according to the features of claim 45, ie as a single method, the superstructure is not yet fixed with the necessary torsional resistance. By means of a step of allowing it to be mounted on an artificial tooth root Is achieved.

Due to the fact that the dental prosthesis device includes a reference device associated with the jawbone of the patient used as the positioning device, it is possible for the positioning device to very accurately position and orient the artificial root used for attachment. This makes it easier to match the prosthesis with the superstructure with prefabricated fixation device while minimizing the risk of error. Because of this, no continuous adjustment of the prefabricated elements is required at all or at least smaller than that required in the techniques used so far. Due to the fact that the required processing time is relatively short, the cost of fixing the dental prosthesis is reduced as well as the discomfort and pain of the patient. The device and its components according to the invention enable the use of a one-time sourced superstructure implant method. Best of all, there is no need to wait three to six weeks, which was normally required for the prosthesis to ossify to achieve the torsional resistance required to withstand significant loads. Therefore, the superstructure can be implanted early, and in fact, the superstructure can be implanted immediately after fixing the artificial root.

In a preferred embodiment of the invention, the reference device comprises a first prosthetic artificial root secured to the jawbone. Since the reference device is used to guide the positioning device into position, the best accuracy of the relative positioning and orientation of the other artificial root is ensured.

In another preferred embodiment, the positioning device comprises a drilling jig. With this, since the drilling jig is aligned by the reference device, since the hole for the artificial tooth can be formed in a well defined position, an upper structure which is attached very accurately to the artificial tooth root in succession is fixed to the fixed artificial tooth. It will have prefabricated fixation elements positioned in a tailored manner.

The superstructure can be properly aligned as an individual bar with a fixation device and also has a dental prosthesis bridge that can be attached to the bar. In another preferred embodiment of the invention, the fixation device is aligned directly on the dental prosthesis bridge.

In another preferred embodiment of the invention, a deforming device is provided between the support surface on the artificial tooth root and the bearing surface of the corresponding attachment unit. Although accuracy is obtained, if a certain alignment change and / or height change occurs in any artificial root, it can be absorbed by the deforming device.

Other embodiments of dental prosthetic devices, positioning devices and superstructures are described in the dependent claims.

The invention is explained in more detail in the following detailed description of the preferred embodiments of the invention with reference to the accompanying drawings.

1 and 2 illustrate the main parts of a dental prosthesis device according to the invention. These are shown more clearly in the exploded view of FIG. 1. An artificial tooth root 1 (shown as three in this embodiment) is fixed to the bone tissue 7 (see FIG. 2) of the lower jawbone of the person. Each artificial tooth root comprises a fixing part 3 and a spacer part 2 attached to the fixing part by, for example, a threaded joint. The bar 4 has three through holes 8 and the position of the through holes coincides with the exposed ends of the spacer portions 2 of each artificial tooth 1 so that the bars 4 are exposed at these exposed ends. Can be combined above. The screw 9 penetrates each hole 8 of the bar 4 and is screwed into the bore 40 of the spacer portion 2, thereby attaching the bar 4 to the three artificial roots 1. The bar 4 is provided with a prosthetic bridge 5 supporting a dental prosthesis (not shown in FIGS. 1 and 2). The prosthetic bridge 5 is attached by four retaining screws 6, each retaining screw passing through a corresponding hole 11 of the prosthetic bridge and screwing into an internal threaded bore 12 at the top of the bar 4. Combined. 2 shows a state in which the tooth bridge is fixed to the jaw bone 7 by the aforementioned elements.

FIG. 3 is a bottom view of the bar 4 shown in FIG. 1, showing the location of three holes 8 coupled into three artificial tooth roots.

FIG. 4 is a side view showing the dental prosthesis mounted on the dental prosthesis bridge 5 of FIG. 2.

In the device shown, all parts included in the superstructure, for example the bar 4, the dental prosthesis bridge 5 and the retaining screw 6, are made of prefabricated elements. Supplying the dental prosthesis bridge and screw in this way as a standard unit does not pose a problem. The main difficulty lies in the bar 4, which must be attached to a number of artificial roots that are fixed to the jawbone of a unique person. To enable this, the artificial root must be fixed to the jaw bone in an interrelated position that coincides with the corresponding position of the bore 8 including the attachment holes of the standardized bar 4. In addition, the artificial roots must be exactly parallel to each other.

To realize this, as described above in the introduction, it is known to drill a hole for the artificial tooth in the jaw bone 7 using a drilling jig. However, when the drilling jig is applied to the dental prosthesis technology, at present the artificial tooth fixed to the hole is drilled with sufficient precision to ensure that it exactly matches the prefabricated bar with a standardized position for the attachment hole 8. It is impossible to provide a hall. The following describes how the drilling jig according to the present invention can achieve such precision.

FIG. 5 illustrates the application of a drilling jig to a man's jawbone in a manner that ensures a certain degree of precision. As a first step, a hole for a centrally located first artificial tooth is drilled, which artificial tooth is used as a reference device of the drilling jig 20. Drilling jig 20 has a through hole 21 located in the center, the through hole serves to align the drilling jig 20 on the artificial tooth root (1a) located in the center. By means of a retaining screw 22 of the same type as the retaining screw 9 used to screw the bar 4 in place on the artificial root, the drilling jig 20 is firmly screwed to the reference artificial root 1a. This places the drilling jig 20 in a well defined position. The drilling jig 20 is fixed in this position by a support screw 24 aligned on each side of the reference artificial tooth root 1a and threaded into the jawbone of the person through the hole of the drilling jig. Two through holes 23 are provided at the outer end of the drilling jig 20. These holes serve as guides for drilling the holes required for two different artificial roots.

Here, one set of setting sleeves 25 is used, which is used as a set of drill guide inserts (only one in the figure is shown), each setting sleeve having a set sleeve 25 on top of the drilling jig 20. It is equipped with two cylindrical protrusions 26 which, when disposed in the drill, slide very accurately into the holes 23 of the drilling jig. Each sleeve 25 is coaxial with a cylindrical protrusion and has a pair of through holes 27 that direct the drill bit. The hole drilled in the jawbone consists of three stages. First, a setting sleeve with a relatively small hole 27a of about 2 mm in diameter is used. Using this sleeve, the jawbone is drilled with the corresponding fine drill bit 28a. The drilling jig 27 is then replaced by a similar drilling jig with a hole 27b slightly larger in diameter 3 mm, which holes are used to drill with a second drill bit 28b of a corresponding size. . In step 3, a drilling jig with a hole 27c about 4 mm in diameter is used to finally drill the artificial root hole in the jawbone, for which a large drilling bit 28c is used.

The holes drilled for the two lateral prostheses are positioned very accurately due to the well defined drilling jig 20 position in the patient's jawbone. This is achieved by a central artificial root 1a which serves as a reference and serves as a reference, a guide hole 23 positioned precisely with respect to the central artificial root 1a, and three setting sleeves 25. . In addition, the clearance between the hole 23 and the protrusion 26 and the clearance between the holes 27a to 27c and the drill bits 28a to 28c are sufficient to ensure that the three artificial tooth holes in the jaw bone can be parallel. In addition to being minimal, the holes 23, the corresponding protrusions 26 and the holes 27a to 27c are sufficiently long in the axial direction.

Thereafter, two side artificial roots are fixed in the formed holes. This fixation process is shown in the exploded view of FIG. 6, and the state after the artificial tooth is fixed to the jawbone is shown in FIG. 7. The same drilling jig 20 that is used to make the hole continues to be used to apply the artificial tooth. A fourth sleeve 30 used as an artificial tooth guide insert with a cylindrical protrusion 31 corresponding to the hole 23 of the drilling jig is coupled to the drilling jig 20. The artificial root guide sleeve has a hole 32 that penetrates the protrusion and is arranged in the same manner as in the drill guide sleeve. Each hole 32 of the artificial tooth guide sleeve has a diameter through which the alignment element 33 can be received and precisely coupled. The alignment element is equipped with a through hole 34 for the artificial root mounting screw 38. The bottom of the alignment element is provided with a recess 35 of hexagon slightly wider than the through hole and a bore 36 that is shallower and slightly wider than the recess. The width and length of the recess 35 are adapted to the hexagonal neck 42 at the top of the spacer portion 2b of the artificial tooth 1b, the second bore 36 of the spacer portion 2b. It has a diameter corresponding to the outer shell surface 41.

In addition, the alignment element 33 is provided with a radial flange 37, when the alignment element 33 is installed, the flange contacts the top side of the setting sleeve 30, thereby providing a reference in the vertical direction. Done.

The lower end of the installation screw 38 is provided with a threaded portion 39 engaged with the internal threaded bore 40 of the spacer portion of the artificial tooth root 1b.

In the installation process, by screwing the threaded portion 43 of the spacer portion 2b to the internal threaded bore 44 of the fixed portion 3b of the artificial tooth 1b, the fixed portion 3b of the artificial tooth 1b. And spacer portion 2b are combined to form a single unit. In addition, the mounting screw 38 passes through the hole 34 of the alignment element 33 so that the bores 35, 36 of the alignment element surround the corresponding portions 42, 41 of the spacer portion 2b. It is screwed into the bore 40 at the top of 2b.

Accordingly, not only the installation screw 38 and the alignment element 33 but also the spacer portion 2b and the fixing portion 3b of the artificial tooth 1b pass through the holes 32 of the sleeve 30 as a single unit. The outer shell surface 45 of the alignment element 33 is joined to the hole 32 of the sleeve 30 and guided by the hole. Thereafter, the mounting screw 38 is tightened. Since the installation screw has already been tightened to the bottom of the bore 40 of the spacer portion 2b and the spacer portion 2b is screwed to the fixing portion 3b, tightening the installation screw 38 causes the artificial tooth root 1b. Is screwed into the hole drilled in the jawbone. Thus, the lower end of the artificial tooth root 1b is automatically tapped in a known manner, screwed down and fixed in the drilled hole. Tightening continues until the top side 47 of the sleeve 30 defining the correct threading depth and the flange 37 of the alignment element 33 contact. This is most clearly shown in FIG. 7.

8 is a perspective view showing the installation of an artificial tooth root. Once the lateral prosthesis is secured in this way, all elements used in the installation are removed, such as the installation screw 38, the alignment element 33, the sleeve 30, the drilling jig 20 and the support screw 24. .

Immediately thereafter, the bars 4 shown in FIGS. 1 to 4 can be screwed firmly into place on the artificial tooth root in the manner described in connection with these figures. After about 8 days of healing, the tooth bridge may be attached to the bar. During the waiting period, it may be desirable to attach a soft bar to the bar 4 to prevent the bar from wearing out.

In spite of the precise positioning of the artificial root in order to obtain a suitable position and orientation with respect to the anchoring device of the bridge foundation, inadequate defects may remain, especially with respect to the mutual alignment direction of the artificial root. It is difficult to fully implement the mutual parallelism between the prostheses. This problem is described in more detail in Swedish Patent Application No. 9602555-6, filed under the name “artificial root, prosthetic fixture and prosthesis,” which is referred to herein.

In order to solve the problems caused by the misalignment between the support surface of the artificial tooth and the corresponding bearing surface of the superstructure, a deformation device is provided on the support surface of the artificial tooth. One embodiment of the deforming device is shown in FIG. 9, which shows an artificial tooth 101 with a fixed end secured to a person's lower jaw 102. The attachment at the upper end of the artificial tooth 101 includes a bar 103, which is aligned to support a tooth prosthesis bridge (not shown) attached to the bar.

The fixing portion 107 of the artificial tooth 101 is configured in a conventional manner so as to have a threaded portion 104 with a conical portion 105 provided with a slot 106 at its end. The fixing part 107 made of titanium is screwed by automatic tapping into a hole pre-drilled in the jawbone 102. The upper end of the artificial tooth root, which is the anchoring end, includes a spacer portion 108, which is integral with the fixing portion 107 to form a single part, or more typically, an internal screw (see FIG. 9). Not shown) may be a separate unit that is screwed into the provided fixing portion 107 bore.

The securing end is provided with an attachment unit for engaging another securing unit adapted to be applied on the bar 103, the two being secured to each other. The attachment unit at the securing end includes a support surface 109 aligned perpendicular to the longitudinal axis A of the artificial root. The attachment unit also includes an axially aligned projection 110 extending from the support surface 109 and an internal threaded bore 112 of the artificial tooth. The bore 112 is axially aligned with respect to the top of the protrusion. Corresponding attachment units of the bar 103 include some bottom surface including bearing surface 113, through bore 114, cylindrical conical bore 115 at the top of the bore, hexagonal conical bore 116 at the bottom of the bore, and retaining screw. 117.

Bar 103 defines a direction that depends on the direction of the first artificial tooth root (not shown). Efforts have been made to observe whether the normal alignment B in this direction corresponds to the depicted direction of the artificial root 101. This is the case not shown in the figure. Instead, there is a deviation of α ° between them. Corresponding angular deviations also occur between the support surface 109 and the bearing surface 113.

The support surface 109 of the artificial root is provided with a deformation device in the form of a flange 118 aligned with the outer periphery of the support surface 109 and extending axially from the support surface. This flange is relatively thin, about 0.05 mm, and about 0.15 mm high. When the artificial root 101 is firmly pulled toward the bar 103 by tightening the screw 117, a portion of the support surface of the artificial tooth root made of the flange is in direct contact with the bearing surface 113 of the bar 103. Since these surfaces are not parallel, the initial contact is made at one point on the flange 118. If the screw continues to tighten, the flange 118 will plastically deform at this position, and if the screw is further tightened, the deformation will extend across the flange 118. The flange 119 modified in this way is shown on the left side of the drawing. The deformed flange results in an end surface that is parallel to the bearing surface 113 of the bar 103 and in contact over the entire range. As a result, each deflection α is compensated, whereby good contact between the artificial tooth 101 and the bar 103 is achieved, and deformation of the jaw bone 102 does not occur. Instead of the flange, a ring-shaped washer that can be plastically deformed may be disposed on the support surface of the artificial tooth root.
