Definitions
- the present invention relates to a modular implant for dental prostheses comprising a base provided with means for stable, but reversible, engagement with a corresponding element for closing the base. It is known in the art relating to the implantation of dental prostheses that there is the need to replace the cavities resulting from the loss of teeth with prostheses made of synthetic material of various types. It is also known that, in order to be able to install in a stable manner said prostheses in the associated seat, it is necessary to provide a fixed pin onto which the tooth itself is cemented. The arrangement of said pins is basically performed in two ways: direct screwing of the pin onto the jaw bone
- endosseous implant or, in the case where the bone has deteriorated and does not allow direct screwing of the pin, the positioning, on the bone, of bases made of biocompatible alloys carrying the pin (juxtaosseous implant) .
- a modular implant for dental prostheses comprising a base provided with means for stable, but reversible, engagement with a corresponding element closing the base in the area underneath the gum and with means for supporting the false teeth.
- Figure 2 shows a cross-section along the plane indicated by II-II in Fig. 1;
- FIG. 3 shows a front view of a multiple implant according to the invention
- FIG. 4 shows a partially sectioned front view of the multiple implant arranged in position
- Figure 5 shows a cross-section along the plane indicated by V-V in Fig. 4; - Figure 6 shows a cross-section, similar to that of Fig. 5, of the implant after mounting of the pin in place of the cap; and
- Figure 7 shows a variation of an example of embodiment of the means for supporting the teeth in the case of a full prosthesis.
- the implant 10 is composed of a substantially cylindrical or frustoconical base 11, the bottom part of which is formed in the manner of a fork (Fig. 2), the opposite arms lib of which are integral with a strip 12 of suitable material extending in a substantially transverse direction with respect to the longitudinal axis X-X of the base 11.
- Said transverse strip 12 is made from material of limited thickness and provided with holes 12a and, during casting, performed on the basis of the imprint of the bone 20 taken beforehand, assumes the shape corresponding to that of the bone 20 itself so as to allow perfect adaptation to the surface of the latter on which it is placed (Fig. 4) .
- the base 11 has, formed inside it, a female thread 11a designed to engage with the threading 13a of the shank 13b of a cap 13, the top end 13c of which is provided with a hexagonal operating seat 13d.
- the modular implant 10 according to the invention may be constructed in multiple form in all those cases where it is required to replace a plurality of teeth with a corresponding number of prostheses .
- the implant may advantageously be applied in the form of either a single module or multiple module consisting of up to eight elements distributed along the dental arch and joined together by transverse strips 12 which extend along the jaw bone 20.
- Figs. 4 and 5 show how the implant 10 is arranged in position:
- the gum 30 is opened and the implant 10 (which in the Figures is of the multiple type) is placed on the bone 20 so that the bases 11 are arranged inside the said seats 21 and the inside bottom part of the fork rests axially on the bone 20 on which the strip 12 integral with the opposite arms lib of the fork(s) is also rested (in the transverse direction with respect to the axial direction of the base) .
- the implant 10 which in the Figures is of the multiple type
- the threaded holes 11a are closed with the caps 13 and the implant is covered with a granular synthetic material 40 which, over a certain period of time (50-60 days) , becomes hard bone, mixing with the haematic fibrin and securely fixing the implant also owing to the presence of the holes 12a on the transverse strip 12.
- the gum 30 is closed over the base 11 and the cap 13, so as to allow the synthetic material 40 time to harden.
- the gum 30 is opened again in the region of each base 11, the cap 13 is unscrewed and a corresponding pin 50 (Fig. 6) , onto which the false tooth will be cemented, is screwed in.
- the base may be applied in a combined endosseous and/or juxtaosseous manner, solving the problems associated with those cases where the bone is particularly fragile and unable to support a screw screwed directly inside it;
- FIG. 7 shows a variation of an example of embodiment of the implant according to the invention, suitable for application to an entire dental arch: in this case the bottom part remains unchanged, but an arch 150 is mounted on the bases and fixed in position by means of stud bolts 151 inserted into corresponding through-seats 152a of columns 152 integral with the said arch 150 and provided at predefined intervals along the length of the arch 150 corresponding to the position of the bases 11 onto the female threads 11a of which the said stud bolts 11a are screwed.
- the arch 150 replaces the individual pins 50 in those cases where it is required that the whole dental arch should be extractable.
