- One of the two end pieces is firmly connected to the web 92.
- the other end piece 92.1 for example, axially verstel lbar provided on the web 92 and formed, for example, by a seated on the web 92 rubber ring.
- the web 92 is roughened at least on its to be connected to the tooth or root rest 2 surfaces.
- the web 92 is preferably prefabricated in different lengths, ie part of a web set with webs 92 of different lengths, for example with a length of 8 mm, 10 mm and 15 mm.
- FIG. 40 shows a schematic representation of a device 92 for gentle
- FIG. 41 shows, as a further embodiment, a device 97 for gently extracting a tooth or root remnant using a ring or circular spring 98, which in turn engages at its lower region in FIG. 41 via the armature 96 at the tooth or root remnant 2.
- the circular spring 98 is attached to a support 99, which in turn is fixed in a suitable manner to at least one or to two of the tooth or root rest or the treatment area adjacent teeth.
- the circular spring 98 is formed so that it has an oval shape in the relaxed state, in which the larger cross-sectional axis extends horizontally or substantially horizontally.
- the strained circular spring 98 connected to the tooth or root remainder 2 has a round or substantially circular cross-section or an oval cross-section in which the larger cross-sectional axis is vertical or substantially vertical, i. oriented parallel or substantially parallel to the axis of the tooth or root remnant 2.
- FIG. 42 shows, in greatly enlarged representation, a clamping element 100 with a bolt 102 axially displaceable in, for example, a bow-shaped base 101, an elastic element 04 acting between the base and a bolt end 103 provided with a bolt head 103 and with a tensioning lever 105 which is in contact with an eccentric surface the base 101 abuts, by pivoting in one direction the bolt head 103 moves under tensioning of the element 104 in the direction of the base 101 and by pivoting in the opposite direction, the bolt 102 is free for movement through the element 104 or for generating a clamping force B.
- Das Clamping element 100 may, for example, instead of the respective
- FIG. 43 shows, in greatly enlarged representation, an extraction device 106 for gently extracting a tooth or root residue 2.
- the action element producing the extraction force A on the tooth or root remnant 2 is in this embodiment a shaped body of a tooth-colored elastic material (eg elastomeric plastic).
- FIG. 44 shows, in a simplified representation, an extraction device 109 which is shown in FIG. 44
- Substantially consists of the base 101, which in turn at one or more
- a sleeve 1 10 is guided axially adjustable by means of a thread.
- a spring element such as a compression spring or tension spring, in the extraction direction A.
- the tensile and / or compressive force of the spring element acting on the pin 102 is at least twice adjustable, once by adjusting the sleeve 1 10 with the tool 1 1 1 and on the other to adjust the point of attack of Spring element 109.1 on the sleeve 1 10 with the tool 1 1 1 .1.
- FIG. 45 shows, in a simplified representation and in section, an action element 9e which corresponds to the action element 9c with respect to its use and which has a
- predetermined extraction stroke allows and essentially one-stop
- Action element 9e activated, for an extraction stroke corresponding to the axial length of the separate sleeve portion 1 12.1.
- Figure 46 shows a simplified representation and in section an action element is in a tooth or root rest to be anchored sleeve 1 14 made of biocompatible material and anchored at the lower end in the sleeve tension spring 1 15.
- the tension spring is for this purpose at its lower end with a helical Provided section which is screwed into a thread of the sleeve.
- the tension spring itself can form a threaded end with its turns, which can be anchored in a thread 1 16 of the sleeve 1 14 by screwing.
- Figure 47 shows a simplified representation of a starting material 1 1 7 for forming an anchor, which corresponds to its function, for example, the anchor or the base 7.
- Material consists of at least two-layered sections 1 18. From fiber-reinforced plastic and between these sections 1 18 formed areas 1 1 9, which are for example tapes or only from the fibers or from the uncured, the fibers containing plastic. In use, sections 1-18 are fixed to existing teeth (e.g., by sticking). Subsequently, the sections 1 18 are cured or impregnated with hardenable plastic and then cured so that then between the adjacent sections 1 18 a fixed bridge is formed.
- the sections 118 can also be formed in three dimensions, for example adapted or approximated to the shape of the outer surface of a natural tooth, and / or as caps, crowns, rings, etc.
- Figure 48 shows diagrammatically and in plan view various shapes of the pins 14, namely cylindrical, conical and bulged with at least one bulge and / or bore.
- Figure 49 shows various embodiments of the pin 14 in cross-section, rectangular, at the top with at least one bulge or central reinforcement, in
- the pins 14 are, for example, grooved in the longitudinal or transverse direction or notched with a diamond pattern on the
- the pins 14 may also be formed like a tube with inner and / or outer structure.
