A spacer and a screw are engaged with a holder in a rotationally fixed position with respect to the holder. The spacer is engaged in a spacer engaging portion of the holder and the screw is engaged in a screw engaging portion of the holder. The screw is inserted in a threaded receiving passage of the implant such that threads on the screw engage threads of the receiving passage. A rotational motion is applied to the holder, thereby rotating the rotationally fixed spacer and screw and screwing the screw into the receiving passage of the implant. A cooperation between a bearing surface of the spacer and a top surface of the implant is established at a predetermined position of screwing. The holder is separated from the spacer and the screw.
FIELD OF THE INVENTION The present invention relates to, inter alia, a method for securing a spacer to a firmly integrated implant, preferably in the jaw bone, by means of a holder and with the aid of a screw. The threaded part of the screw will extend through a recess in the spacer so that its thread cooperates with the thread of the implant. The screw head can moreover cooperate with a tightening and locking surface in the spacer, which also has a bearing surface which can cooperate with a top surface of the implant. The invention also relates to an arrangement for application of this method. The invention relates in addition to the use of the holder for securing a spacer in an implant by means of a screw.
BACKGROUND OF THE INVENTION After the implant has become firmly integrated in the bone, which normally takes 3 to 6 months after fitting the fixture or implant, a spacer is attached. In this connection, an incision is made through the gum so that the upper surface of the implant is exposed.
SUMMARY OF THE INVENTION The object of the invention is, inter alia, to solve these problems, and the feature which can principally be regarded as characterizing a method according to the invention is that the screw, in its position passing through the spacer, and the said spacer are first held together in a rotationally fixed manner in the holder, so that the bearing surface of the spacer protrudes beyond the holder, and the threaded part of the screw in turn protrudes beyond the bearing surface. Further features are that the rotationally fixed unit thus established by the holder, the spacer and the screw is thereafter applied to the implant in a position of cooperation of the threads of the implant and screw. The unit is then given rotating movements, during which the thread of the screw is screwed down into the thread of the implant. At a predetermined position of screwing, preferably where the cooperation between the bearing surface of the spacer and the top surface of the implant has been established, the holder is separated or detached from the spacer and the screw by means of a separating movement, for example a deflecting movement, which is preferably distinct from the rotating movement. The screw head is exposed for possible further tightening.
BRIEF DESCRIPTION OF THE DRAWINGS Presently proposed embodiments of the method, arrangement and use having the characteristics of the invention will be described below with reference to the attached drawings, in which:
DETAILED EMBODIMENT In FIG. 1, a holder is indicated by 1. The holder comprises an elongate part 1 a and a widened part 1 b arranged on the elongate part. The holder can be made of plastic material, the part 1 a can be a substantially solid part and the part 1 b has an end recess, in accordance with what is described below. The holder has a length L of about 20 mm and a diameter D of about 3 mm in part 1 a. The part 1 b has a diameter D′ of about 5 mm. The parts merge into each other via a bevel 1 c. Applied to the holder in a rotationally fixed manner there is a spacer 2 which protrudes beyond the end surface 1 d of the holder via a part which has a bearing surface 2 a. In accordance with what is described below, a screw is applied to the holder and extends through a recess in the spacer so that its threaded part protrudes beyond the bearing surface 2 a. The screw is indicated by 3 and the threaded part of the screw by 3 a, while the thread itself is indicated by 3 b. FIG. 1 also shows an implant or fixture 4 which has become firmly integrated in a bone, preferably in a symbolically indicated dentine 5. The implant or the fixture can be of a type known per se and has one or more external threads 4 a. The implant is screwed into a hole 6 formed in the bone. The implant is also provided with a top surface 4 b against which the bearing surface 2 a of the spacer is intended to bear when the spacer has been screwed into the implant by means of the screw 3. The implant also has an internal thread 4 c with which the thread 3 b of the screw can be screwed. The implant is also provided with a hexagon, by means of which the implant can be screwed down into the hole 6 formed in the dentine 5. FIG. 1 shows a position 7 in which the holder has been moved into position near the implant for cooperation between the threads 3 b and 4 c. In accordance with FIG. 2, the spacer can be designed in a manner known per se. Thus, a bearing part 2 b is included for the head 3 c of the screw. The bearing recess of the part 2 b for the screw head 3 c is indicated by 2 c. At the screw head 3 c, the screw is also provided with a projecting flange or tabs 3 d which cooperate with a top surface 2 d of the spacer element. The part 1 b of the holder is provided with an end recess 1 e. The spacer 2 is introduced into this recess 1 e. At the lower end, the spacer has a recess 2 e. The end part 1 b also has a second recess 1 f in which the upper part of the screw head is introduced. The part 1 b is also provided with an inwardly directed flange 1 g or flange parts which can cooperate with the outside of the spacer part 2 a. The spacer part 2 a and the said inwardly projecting flange/flange parts are chosen so as to give a rotationally fixed anchoring for the spacer 2 in the part 1 b. The recess 1 f is chosen with a diameter dimension or a corresponding dimension in relation to a part 3 e of the screw which projects into the recess 1 f so as to give a rotationally fixed function. The recess 1 f can be cylindrical or has a polygonal shape corresponding to the shape of the screw at the said inserted part 3 e. The arrangement is thus such that both the spacer and the screw are given a rotationally fixed anchoring in the holder 1.
