    SUPERSTRUCTURE AND METHODS FOR MANUFACTURING THE SAME Technical field The present invention pertains to a dental superstructure attaching system foruse with a dental implant. More specifically the present inVention pertains to a systern tobe arranged in between a dental implant and a dental superstructure/ framework,members thereof, and methods for attaching a dental superstructure to a dental implant via such a system.
    Background The goal of a dental implant system is to restore the patient to normal fiinction,comfort, aesthetic, speech and health regardless of the current oral condition. Theseimplant systems are based on the implantation of dental implants, such as dentalimplants made of biocompatible titanium, through insertion into the patient's jawbone.In this respect, the use of biocompatible titanium started in Sweden as early as 1950,and has since then been further developed and spread world-wide. During the 1980' s anumber of implant systems entered the world market.
    When securing a dental prosthesis to the j aw of a patient, it is commonlyknown to attach a superstructure to osseointegrated dental implants. However, since theposition and angle of the dental implants Vary greatly from patient to patient, the use ofangled distances is common. These distances are placed upon the dental implant, andthe superstructure is then most often cemented to the distances, since it is difficult toretain the superstructure to such distances by means of screws. However, when usingseparate distances, these will ineVitably extend - at least to some extent- in the axialdirection of the dental implant. It is then often Very difficult or even impossible to applythe superstructure on such distances, since the application of the superstructure calls fora substantially parallel arrangement of the distances. Also, the mounting process whenusing such distances is very complicated and cumbersome, since a Vast number ofdifferent distances must be tested on the implants, to find the needed match. Also,interfaces between the distances and the superstructure are hygienically bad.
    WO01/ 70127 describes an arrangement comprising a spacer element for animplant. The spacer implant has a screw bore at a fixed angle relative the longitudinalaxis of the implant, such that a holder configured to support a superstructure may bemounted in said screw bore at the corresponding angle. Hence, using this kind of system the mouth of the connection channel between the superstructure and the spacer element may be arranged with a freedom of choice in accordance with the angle of the screwbore of the spacer element.
    However, the freedom of the above described system is limited to the pre-deterrnined angle of the spacer element, and the system requires specially adapted toolsfor assembling the arrangement.
    Thus, there is a need for a new device and method allowing for improved construction of angled distances.
    Summary of the invention Accordingly, the present invention preferably seeks to mitigate, alleviate oreliminate one or more of the above-identified deficiencies in the art and disadvantagessingly or in any combination and solves at least the above mentioned problems byproviding a method and a device according to the appended patent claims.

    Further advantageous features of the invention are defined in the dependent claims.
    Brief Description of the Drawings These and other aspects, features and advantages of which the invention iscapable of will be apparent and elucidated from the following description ofembodiments of the present invention, reference being made to the accompanyingdrawings, in which Fig. 1 is a schematic cross-section of a system according to an embodiment; Fig. 2 is a schematic cross-section of a longitudinal member of the system shown in Fig. 1; Fig. 3 is a schematic cross-section of a casing according to an embodiment,housing a longitudinal member according to Figs. 1 and 2 therein; and Fig. 4 is a schematic cross-section of a casing according to Fig. 3.
    Description of embodiments Several embodiments of the present invention will be described in more detailbelow with reference to the accompanying drawings in order for those skilled in the artto be able to carry out the invention. The invention may, however, be embodied in manydifferent forms and should not be construed as limited to the embodiments set forthherein. Rather, these embodiments are provided so that this disclo sure will be thoroughand complete, and will fully convey the scope of the invention to those skilled in the art.The embodiments do not limit the invention, but the invention is only limited by theappended patent claims. Furthermore, the terrnino lo gy used in the detailed descriptionof the particular embodiments illustrated in the accompanying drawings is not intendedto be limiting of the invention.
    In general, the present invention pertains to a system and devices thereof, forobtaining a dental superstructure, and subsequently a dental prosthesis, comprising saiddental superstructure and an appropriate facing material thereon, without any form ofscrew channel mouth in the masticating surface. The system instead assures that thesuperstructure may be attached to a dental implant through a tightening screw lingually.In this way a more aesthetic and endurable construction may be obtained.
    According to the embodiment in Fig. 1 and Fig. 2, a dental implant connectingmember 101 and a longitudinal member 102 are disclosed. The dental implantconnecting member l0land the longitudinal member 102 are parts of a superstructureattachment system, said system comprising the dental implant connecting member 101,the longitudinal member 102, and a casing 200, according to Figs. 3 and 4. Thelongitudinal member 102 is adapted to be inserted into a casing 200, in accordance withFigs. 3 and 4, which will be further described below, which in tum is connected toadental superstructure. The longitudinal member 102 comprises two portions, a mainmember l02a and a lever member l02b, which in use are held together by a screwmember arranged in a correspondingly threaded screw hole 103. The two membersl02a, 102b have a substantially longitudinal extension, and are intended to extenddistally from the implant connecting part 101, and therefore also distally from the jaw bone to which an implant (not shown) is secured. The screw hole 103 extends substantially transversally in respect of the longitudinal extension of the two members102a, 102b, and runs at least through portion 102a.
    The thread of the screw hole 103 may be such that at least a part of the screwhole 103a in portion 102a is threaded. Portion 102b may comprise a receiving seat103b, for receiving the screw member arranged in the screw hole 103a and protrudingfrom an interface surface 105a on the portion 102a. In this way, the portion 102a may bepushed away from the portion 102b by screwing the screw member into the screw hole103 and pushing onto the receiving seat 104. The portion 102b may also have athreaded part in the receiving seat 104. In this way the screw member may beprearranged in the screw hole, holding portion 102a and 102b together duringapplication of the casing 200 thereon. The thread of the screw hole part in portion 102bmay be threaded in the opposite direction to the thread in the screw hole 103a of portion102a. In this way the separation action between portion 102a and 102b may beamplif1ed, such that portion 102a and 102b are separated by two thread heights duringevery rotation of the screw member arranged in the screw hole 103.
    The implant connecting member 101 and the longitudinal member 102 areconnected to each other at a curved interface area 106 forming a ball-socket joint. Theball-socket joint is formed by a partially spherically shaped protrusion 110 arranged atthe distal end of the dental implant member 101, and a recess 104a, 104b having acorresponding inverted shape and configured to engage with said protrusion 110.
    In Figs. 3 and 4, a casing 200 is disclosed, in accordance with one embodimentof the invention. The casing 200 is to be inserted into a cavity in a dental superstructure.In this way, the dental superstructure can be provided with a predeterrnined cavity forreceiving the casing 200, which cavity has a shape and size being known to for examplethe CAD/CAM equipment milling or shaping the dental superstructure. Within thecasing 200 the longitudinal member 102 is intended to be received. In this way, thecasing 200 may be manufactured in material being more resistant to strain and stressthan the material of the dental superstructure. For example the casing 200 may bemanufactured in stainless steel, titanium, CoCr etc., making it possible to manufacturethe dental superstructure in more fragile materials, such as plastics. The casing 200 issubstantially cylindrical, with a tubular cavity 201, extending into the casing 200 fromthe proximal end thereof The distal end of the casing 200 is preferably closed, such thatthe cavity 201 ends in a distal bottom end wall 202. The cavity is adapted in size and shape to receive the longitudinal member 102.
    The casing 200 is provided with a proximal outer shoulder 203. In this way -since the dental superstructure is manufactured and shaped to correspond to this exactcavity - the dental superstructure may bear upon the outer shoulder 203, which willfacilitate arrangement and fixation of the casing into the dental superstructure and alsodistribute tensions and stresses between several cavity/casing positions in one dentalsuperstructure, once the dental superstructure has been fixated to the dental implant, inaccordance with below.
    In the proximal end of, i.e. at the opening 204 of, the cavity 201 a ledge 205 isformed. The ledge 205 is adapted in size and shape to correspond to the flange 107 ofthe longitudinal member 102. The interaction between the ledge 201 and the flange 107creates a pivot point for said lever member 102b. Since the casing 200 has apredeterrnined shape corresponding to the longitudinal member 102, the cooperationbetween the flange 107 and the ledge 205 may be close, to minimize movement andplay between the two.
    The casing 200 has a tubular wall 206, in accordance with above. The tubularwall 206 is provided with a through hole 207. The through hole 207 communicates withsaid cavity 201. The position of the through hole 207 corresponds in position to thethrough hole 103a of said main member 102a. The through hole 207 is also positioneddistally of the proximal outer shoulder 203 and distally of the proximal ledge 205.
    The functionality of the superstructure attachment system will now bedescribed. The dental implant connecting member 101 is tightly attached to the dentalimplant by a screw 109 threadably engageable with the dental implant. The mainmember 102a and the lever member 102b of the longitudinal member 102 are f1tted toengage with partially spherically shaped distal end of the implant connecting member101. As the lever member 102b and the main member 102a are in close contact alongtheir longitudinal axis, the longitudinal member 102 may be angularly displaced relativethe longitudinal axis of the implant connecting member 101 by means of the ball-socketjoint formed at the interface between the implant connecting member 101 and thelongitudinal member 102.
    Then, casings 200 are inserted into pre-shaped cavities, corresponding to theouter shape of the casing 200, and adhered thereto through gluing or cementing. Thecasings 200 then receive the longitudinal members 102 in the cavities 201 thereof Thecavities of the casings 200 are shaped such that the proximal mouth for receiving thelongitudinal member comprises a seat, in form of the ledge 205, for the flange 107 in a proximal zone of the longitudinal member 102. The cooperation between the flange 107 and the corresponding ledge 205 of the casing 200 will enhance the leverage of theseparation force from separation of the main member 102a and the lever member 102b,since a distinct leverage/pivot point will be formed at the interface between the two.
    When the casings 200 have been slid onto the longitudinal portion and thelongitudinal member 102 consequently is positioned at a desired angle, the screwinserted into the screw bore 103 of the main member 102a is tightened such that itprotrudes outside the main member 102a and consequently causing a relative movementbetween the lever member 102b and the main member 102a. As a distance between thelever member 102b and the main member 102a is induced, the partially sphericallyshaped recess 104a, 104b of the longitudinal member 102 will consequently clamplongitudinal member 102 to the implant connecting member 101, such that thelongitudinal member 102 is tightly connected to the implant connecting member.
    A superstructure may be attached to the system after the position of thelongitudinal member 102 relative the implant connecting member 101 has been secured.Preferably, the superstructure comprises at least one interior channel for receiving thecasings 200, and thereby also the longitudinal members 102. More preferably, each oneof the interior channels is reachable from the oral cavity by an opening, such that thesuperstructure may be further attached to the system by means of a screw. Hence, theopening is aligned with the through hole 207 of the casings 200 and the screw hole 103of the main member 102a of the longitudinal member 102.
    The dental implant connecting member 101 is preferably a two-part piece,comprising a bolt and a f1tting. The bolt has a threaded part 109 and tool receiving part108 such that it may be tightly screwed into the implant. Before the bolt is f1tted into theimplant, it is inserted into the f1tting such that the f1tting will be secured relative theimplant upon tightening of the bolt. For this purpose, the fitting is equipped with aprotrusion 112 and a recess 111 which engage with the implant and/or the bone of thepatient for preventing rotational movement of the fitting relative the implant.
    The tool receiving part 108 is formed as a cylindrical or conical recess in thespherically shaped distal end, wherein the longitudinal axis of said recess is alignedwith the longitudinal axis of the implant. Hence, the distal end is formed as a sphereintegrally formed with the protrusion/recess part 111, 112, with a bore extending fromthe upper end through the sphere.
    With reference to Fig. 2, the longitudinal member 102 will be described inmore detail. Here, the longitudinal member 102 is formed by the main member 102a and the lever member 102b. When the lever member 102b is in close contact with the main member 102a, the longitudinal member is generally extending in a longitudinaldirection and consists of three general parts; a cylindrical part, a flange, and a conicalpart. The cylindrical part is arranged at the distal end of the longitudinal member 102and extends distally from the flange 107. Proximally of said flange 107, a conical part isarranged. The conical part comprises a proximal recess having a curvaturecorresponding to the distal end of the implant connecting member 101. The casing 200is accordingly provided with a cavity 201 corresponding to longitudinal member 102,such that the longitudinal member 102 may be slid into the casing 200.
    The main member 102a and the lever member 102b are facing each other viathe surfaces 105 a, 105b, which form a longitudinal interface between the lever member102b and the main member 102a. The distal portion of the interface between thesurfaces 105 a, 105b is preferably substantially aligned with the longitudinal axis of thelongitudinal member 102, while the proximal portion of the interface between thesurfaces 105a, 105b is preferably angled relative the longitudinal axis of thelongitudinal member 102, such that the interface surface 105a has a normal facingproximally and transversally and the interface surface 105b faces distally andtransversally, with respect to the longitudinal direction of the member 102. In this way,the demounting of the casings 200, and thus the superstructure, from the implantconnecting members 101, and thus the implant, may be facilitated, since thesuperstructure may be lifted in the distal direction once the screw member in screw hole103 stops to exert pressure on the lever member 102b. In this position the superstructuremay be lifted together with the main member 102a, due to the angled arrangement of theinterface surfaces 105 a, 105b in relation to the central axis of the longitudinal member102. Hence, this arrangement of an at least partially angled interface area facilitatesseparation of the main member 102a and the lever member 102b by means of reducingthe risk of that the members are stuck to each other. In other embodiments the angledinterface portion is made longer; e. g., the entire interface area may be angled relativethe longitudinal axis of the longitudinal member 102. The interface area formed by thesurfaces 105a, 105b, when viewed from above, may also be planar or curved.
    Preferably, the interface between the surfaces 105a, 105b is ending at aposition being located at the center of the spherical recess 104a, 104b of the proximalend of the longitudinal member 102. In other embodiments, however, the interface endpoint could be located slightly off-center.
    As shown in Fig. 2, the through hole 103a of the main member 102a is substantially perpendicular to the longitudinal axis of the main member 102a. The lever member 102b has a corresponding seat l03b for receiving a screw protruding throughsaid main member l02a.
    In other embodiments, the screw hole l03a, l03b may be arranged differentlyand the engaging screw members may then be correspondingly adapted. For example,the screw hole l03a, l03b may extend through both the portions l02a, 102b, but thescrew hole part corresponding to portion l02a having opposite threading direction thanthe threading direction in the screw hole part corresponding to portion l02b.Analogously, the screw member may have the corresponding threads, such thatscrewing action on the screw member in the screw hole 103 will result in increasedseparation effect. One rotation of the screw member will then result in a separation ofthe portions l02a, 102b corresponding to two thread heights.
    In further embodiments, the threaded holes l03a, l03b may be arranged at adifferent angle such that the mouth of the through hole l03a is directed slightly distally.
    The diameter of the longitudinal member 102 is preferably in the range of 2 to5 mm, such that it may be accommodated within the oral cavity while still providingsufficient strength and stability to the casing 200, and thus the superstructure. The totallength of the longitudinal member is in the range of 10 to 15 mm, and hence thedisplacement of the lever member 102b relative the main member l02a is sub-millimeter at the most distal end in order to provide sufficient clamping of thelongitudinal member 102 to the implant connecting member 101. Accordingly, thecavity 201 of the casing 200 is adapted to snuggly receive a longitudinal member 102 ina sliding manner.

Rather, the invention is limited only by the accompanying claims and, otherembodiments than the specific above are equally possible within the scope of theseappended claims.
