- an implant 100 is comprised of a fixture 1 and an abutment 40 which is coupled to the fixture 1.
- the fixture 1 comprises a fixture body 10, a neck portion 20 which is integrally formed on an upper portion of the fixture body 10 and a cap 50 which is selectively coupled to a lower portion of the fixture body 10. It is preferred that the fixture body 10 is entirely formed into a tooth shape. For example, the fixture body 10 is firstly bent at a point A so that the outside diameter of the fixture body 10 is gradually reduced, and secondly bent at a point B.
- the fixture body 10 may has a constant outside diameter from the upper end to the lower end, regardless of the tooth shape.
- the stepped form of the fixture body 10 is advantageous in inserting the fixture body 10 into a socket from which a tooth is extracted.
- a plurality of screw threads are repeatedly formed along the circumference of the outer face of the fixture body 10. Therefore, as described below more fully, the contact area between the inside wall of the socket and the outer face of the fixture body 10 is increased so that the fixture body 10 is fixedly mounted on the inside wall of the socket. Further, the screw thread may be changed into various different shapes.
- a cap 50 is mounted on the thread portion 11.
- the fixture body 10 may have various cross- sectional shape corresponding to the forms of the socket and the jawbone, as shown in Figs. 6A to 6C. That is, the fixture body 10 is formed into various shapes, e.g. a circle type, an ellipse type, or a quadrangle type so as to be adapted to various structures of the socket and the jawbone. Further, the size of the fixture body 10 may be also varied. In this embodiment, the fixture body 10 has a constant thickness. However, if necessary, the thickness of the fixture body 10 may be varied, as shown in Figs. 6D and 6E .
- the fixture body 10 is a hollow pillar.
- a partition wall 15 which is formed with a through hole 17 at a center portion thereof.
- the partition wall 15 divides the inner space of the fixture body 10 into an upper abutment receiving portion 18 and a lower nut receiving portion 19.
- a screw 30 is inserted into the through hole 17. A head portion of the screw 30 s caught by the partition wall 15.
- the rest body portion of the screw 30 is positioned in the nut receiving portion 19.
- a ring-shaped protrusion 16 is formed on an upper face of the partition wall 15.
- a groove 36 On a bottom face of the head portion of the screw 30 corresponding to the ring-shaped protrusion 16, there is provided a groove 36.
- the ring-shaped protrusion 16 may have various kinds of cross-sections, e.g. a trapezoid, a triangle or a circle type.
- the head portion of the screw 30 may have a ring-shaped protrusion 16', and a groove 36' may be formed on the partition wall 15 corresponding to the ring-shaped protrusion 16', as shown in Figs. 7D to 7F.
- a nut 60 is screwed on the body portion of the screw 30 which is positioned in the nut receiving portion 19.
- the nut 60 has a shape which its outside diameter is gradually reduced from an upper end toward a lower end thereof.
- a through hole 62 is formed m the nut 60. Further, on both opposite outer sides of the nut 60, there are provides guiding protrusions 64.
- the inside wall of the nut receiving portion 19 entirely has a parabola shape, in which an inside diameter is gradually reduced from an upper end of the nut receiving portion 19 corresponding to the point A. Continuously, the inside wall of the nut receiving portion 19 is firstly bent at a point C corresponding to the point B so that the reducing rate of the inside diameter is slowed. Then, the inside wall of the nut receiving portion 19 is secondly bent at a point D so that the inside diameter of the nut receiving portion 19 is increased.
- This shape of the inside wall of the nut receiving portion 19 is an example. If the lower body of the fixture body 10 can be expanded by the nut 60 as will be described below, the shape of the inside wall of the nut receiving portion 19 may be varied into other forms.
- the fixture body 10 is formed with at least one slot 14 which is extended from the point B to the lower end of the fixture body 10.
- the slot has a width in which the guiding protrusion 64 can be fitted and slid.
- the number of the slots 14 is provided responding to the number of the guiding protrusions which are formed on the nut 60.
- the thickness of the fixture body 10 is constant as shown in Figs. 6A to 6C, there are provided two to four slots 14 in each case so that the guiding protrusions are fitted in each slot 14.
- a guiding groove 66 is formed m the nut 60, and a thicker portion 10' of the fixture body 10 is inserted into the guiding groove 66 of the nut 60.
- a male screw 42 so as to be engaged with the female screw 22 formed on the inside wall of the abutment receiving portion 18.
- the cap 50 is screwed on the lower end of the fixture body 10.
- the cap 50 is a hemisphere shape having a receiving groove 52, as shown in Figs. 1 and 2.
- On the receiving groove 52 of the cap 50 there is formed a thread 54 from its upper edge.
- a proper implant fixture 100 which is adapted to the form and size of the socket, is selected. At this time, the screw 30 is inserted into the implant fixture 100 and engaged with the nut 60. The cap 50 is coupled to the lower end of the implant fixture 100.
- the fixture body 10 is inserted into the socket. At this time, since the fixture body 10 is formed into a stepped form, the fixture body 10 is fixedly fitted into the socket.
- the inside wall of the fixture body 10 is pushed outward by the nut 60, whereby the fixture body 10 becomes wider after the point C.
- the expanding rate of the fixture body 10 can be regulated by properly varying the shape of the inside wall of the fixture body 10. If the fixture body 10 is wider outward by the nut 60, the fixture body 10 is tightly contacted with the inside wall of the socket, since the screw threads 12 are formed on the outer face of the fixture body 10. Moreover, since the screw threads 12 respectively have a sharp end, the fixture body 10 can be fixedly contacted with the inside wall of the socket. Referring to Fig. 3, the nut 60 is moved to the point D, whereby the fixture body 10 is completely contacted with the inside wall of the socket.
- the fixture body 10 is completely fixed to the socket, thereby being prevented from shaking. Since the cap 50 is removed from the lower end of the fixture body 10, the lower end of the fixture body 10 is expanded outward. In other embodiment, in case that the fixture body 10 is inserted in the socket without removing the cap 50, since the lower end of the fixture body 10 is not expanded by the cap 50 and stably positioned at a bottom face, there is an advantage that the fixture body 10 is not moved due to the expansion of the fixture body 10.
- the screw 30 is not rotated any more. Further, since the ring-shaped protrusion 16 of the partition wall 15 is fitted to the groove 36 of the screw 30, saliva is prevented from being permeated into the nut receiving portion 19 of the fixture body 10, thereby- being prevented from being infected with a germ contained in the saliva .
- the abutment 40 is inserted into the neck portion 20 of the implant fixture 100. At this time, the shape of the abutment 40 is properly selected into a linear type or an angled type according to the situation. According to the embodiment, the abutment 40 is screwed to the neck portion 20 of the fixture body 10. If necessary, the abutment 40 is attached to the fixture body 10 by an adhesive.
- Fig. 8 is a perspective view of a built-m type implant 200 according to other embodiment of the present invention.
- the structure of the built-m type implant 200 has a similar to that of the implant 100 in Fig. 1.
- the built-m type implant 200 comprises a fixture body 10 integrally formed with the abutment 40. Therefore, the neck portion 20 of the implant 100 is not formed.
- On an inside wall of the abutment 40 of the built-m type implant 200 there is formed a female screw (not shown) .
- a cover 70 formed with a male screw 72 on an outer face thereof is screwed to the abutment 40. That is, after the fixture body 10 is fixed to the socket, the cover 70 is screwed to the abutment 40. Therefore, the operation is very simple.
- the fixture body is immediately inserted into the socket.
- the fixture body is expanded so as to be fixedly contacted with the inside wall of the socket. Then, the abutment or cover is coupled to the fixture body, whereby the operation time is remarkably reduced as well as the operation is simple. Further, since the number of the operation times can be reduced to once, thereby reducing a patient's pain and financial charge.
- the shape of the implant fixture is designed to be similar to a tooth or the cross section of the fixture body is formed into various shapes, e.g., a circle, an ellipse, an triangle, a trapezoid, etc., although the socket and jawbone is small and narrow, the operation efficient is improved.
