Definitions

  • the invention concerns a method and a device for producing growth of bone tissue, as well as a device for securely anchoring an implant in bone tissue by producing growth of bone tissue.
  • the jawbone If the jawbone is much resorbed, it may be difficult to make removable dentures remain in place. Further, it may be impossible to anchor a bridge in the jawbone, sinc this requires a certain minimum thickness of the jawbone in order that the fixtures in which the bridge is screwed can be implanted therein.
  • the minimum thickness of the jawbone must be such that the fixtures can be implanted i their entirety, so that their uppermost end is on a level with the interface of the jawbone with the mucous membran which otherwise runs the risk of being perforated thereby.
  • the jawbone In the upper jaw, the jawbone must, furthermore, be at least so thick that there is no risk of the fixtures pene trating into the sini, which might lead to inflammation causing the fixtures to come loose.
  • the jawbone In the lower jaw, the jawbone must be at least so thick that there is no risk o the fixtures perforating canalis mandibularis (see Fig. 3, Item 12), since this may cause the patient to lose his sensibility in the lower lip. Moreover, the fixtures must, if to be usable, have a certain minimum length. Very shor fixtures (3-5 mm) are not sufficiently anchored in the bone and may therefore come loose when subjected to load. To enable use of bridges when the jawbone is resorbe to such an extent that fixtures cannot be anchored there ⁇ in, enough jawbone must be recreated to enable anchoring. In a prior art method, part of the patient's iliac crest or rib is transplanted to the jaw.
  • the transplanted bone is treated to fit the jaw, and is then screwed onto the existing jawbone by means of fixtures, whereupon the mucous membrane is applied and sewn on.
  • the bone transplant can also be placed in the maxil ⁇ lary sini (Fig. 3, Item 13) to which access is gained by drilling through the buccal bone wall. Then, dentures may be attached in the thus-restored jaw.
  • this method is not only expensive, care-demanding and extremely unpleasant to the patient (in particular old people may suffer from postoperative complaints from the hip), but it is also disadvantageous in that the transplanted bone is gradually resorbed.
  • Guided tissue regeneration is a known technique for creating new periodontal tissue for real teeth. This technique is based on the assumption that only some of the cell types in the jaw have a positive effect on the creation of supporting tissue, whereas other types have a negative effect.
  • the latter i.e. the epithelium, connec ⁇ tive tissue and bone cells, should be prevented from reaching the tooth, whereas the former, mostly from the periodontal ligament, should have free access thereto.
  • "cell-tight" filters or membranes placed near to the tooth are used. The mem ⁇ brane, which is soft, is applied or applies itself to the tooth.
  • a much-used membrane consists of expanded PTFE and is sold under the tradename of GORE periodontal membrane (Gottlow et al J. Clin. Periodontology 1984; 9: 494-503; Pontoriero, R. et al J. Clin. Periodontology 1988; 15: 247-254; Pontoriero, R. et al J. Clin. Periodontology 1989;: 16: 170-174; Gottlow, J. et al 1986; 13: 604-616; Becker, W. et al Int. J. Periodont. Rest. Dent. 1988; 3: 2-16).
  • this technique is said to be useful in connection with fixtures.
  • One object of the invention is to obviate the above inconveniences by providing a method and a device promot ⁇ ing growth of bone tissue.
  • Another object of the invention is to provide a method and a device for securely anchoring an implant in bone tissue.
  • the device used for this purpose serves to obviate the risk of the fixture perforating the flap which, by means of this device, is kept away from the fixture.
  • the perforations of the device permit rapid and adequate revascularisation of the blood clot, so that this does not degenerate before newly-formed blood vessels and bone cells from bone tissue and periosteum have had time to grow in. They increase the oxygen and nutrient supply necessary for the regeneration process.
  • FIG. 1 is a perspective view of an inventive device especially suited for securely anchoring tooth implants
  • Fig. 2 is a cross-sectional view of the device in Fig. 1 mounted on a tooth implant in a jaw
  • Fig. 3 illustrates how the device can be used, both in the oral cavity and in the maxillary sinus after loosening the mucous membrane
  • Fig. 4 is a schematic view of part of a face with an embodiment of the inventive device for producing growth of the cheekbone
  • Figs 5a-c illustrate how the device can be used for reconstructing jawbone resorbed after tooth extractions
  • Fig. 5a being a top view
  • Fig. 5b being a sectional view
  • Fig. 5c being a front view
  • Figs 6-8 illustrate the results of a fixture instal- lation without a calotte, with a perforated calotte according to the invention, and with a non-perforated calotte.
  • Fig. 1 shows a device for securely anchoring an implant in bone tissue. This device is especially suitable for fixtures used for permanently anchoring dentures in the jawbone.
  • the device shown, generally designated 1, substan ⁇ tially has the form of a calotte. Its lower periphery 2 i rounded and, in the embodiment shown, substantially cir ⁇ cular, but it may also be oval.
  • the calotte may be semi- spherical or, as in the Figure, truncatedly semi-sphe ⁇ rical. At the top of the calotte, there is a central opening 3.
  • the calotte is made of a tissue-compatible and inert material, preferably titanium.
  • suitable materials include ceramic materials, e.g. frialite, steel, plastics and hydroxylapatite.
  • the thickness of the calotte is pre ⁇ ferably so small in relation to the size that the calotte is mouldable in the plane of the lower periphery. How ⁇ ever, the thickness should be sufficient to make the calotte vertically rigid.
  • a device intended for securely anchoring a fixture and having a diameter of about 7 mm at the lower periphery 2 may suitably have a thickness of about 0.1 mm.
  • Fig. 1 The embodiment shown in Fig. 1 is formed with perfo- rations 4, which may take up more or less of the surface of the calotte across which they are distributed.
  • the device 1 of Fig. 1 is mounted on a fixture 5 which is screwed into bone tissue 6 by means of a screw 7.
  • the diameter of the opening 3 is smaller than that of the cross-sectional surface of the fixture 5, thu enabling the device to rest on the upper side of the fixture 5.
  • the area of the resorbed jawbone in which the fixture is to be attached is first uncovered by cutting away the flap, i.e. the mucous mem ⁇ brane and the periosteum normally covering the jawbone (designated 8 and 11 in Fig. 2), from the bone and foldin it aside. Then, a hole is prebored in the jawbone, and a fixture 5 is screwed into the bone as far as the thicknes thereof permits.
  • the fixture would not, after healing, be able to withstand the strain from a bridge attached to the fixture, since it is not screwed into a sufficiently thick jawbone.
  • the inventive method and device it is, however, possible to produce growth of the bone tissue 6, thereby achieving satisfac ⁇ tory anchoring.
  • a device 1 of the type shown in Fig. 1 the lower periphery 2 of which defines an area much larger than the cross-sectional area of the fixture 5.
  • fixtures usually have a diameter of 3-4 mm, and that the recommended centre-to-centre distance between the fix ⁇ tures is 7-8 mm. This means that the device 1 must not extend more than about 7 mm in "the direction of the jaw", if it is to be possible to provide adjoining fixtures with the inventive device.
  • the device 1 is attached to the fixture 5 by means of a screw 7, which is screwed into the internal thread 9 in the fixture 5.
  • the device forms a calotte over the fixture 5, a space 10 being formed between the calotte, the bone tissue 6 and the fixture 5. This space will immediately be filled with blood from bleedings aris ⁇ ing upon the uncovering of and the drilling in the bone tissue.
  • the flap is placed over the device 1 and the fixture 5, and is then sewn onto the surrounding tissue.
  • the fixture 5 In a couple of months, cells from the bone tissue 6 and the periosteum 11 will grow into the space 10, whereby the fixture 5 is securely anchored.
  • the flap When the space 10 is entirely filled with bone tissue, the flap may again be loosened, the screw 7 removed, and a bridge anchored in the fixture 5 and the adjoining fixtures, which as well may be anchored by means of devices according to the invention.
  • the fixture 5 thus anchored is able to with ⁇ stand load from the bridge, being completely anchored in the bone tissue 6.
  • the device 1 need not be removed after growth of bon has taken place. Since the device is made of a tissue-com patible and inert material, it may safely be left in the jaw. If one so wishes, it is nevertheless possible to remove the device when the desired bone growth has been achieved.
  • the device 1 is preferably mould able. This is an advantage if the jawbone in which the fixture 5 is to be attached is so narrow that the peri- phery 2 of the device is outside the jawbone when the device has been mounted on the fixture, or if the shape o the jawbone otherwise does not match the device 1. In suc a case, the device 1 may easily be adapted to the jawbone at issue. As already mentioned, the device should however be vertically rigid, the reason being that it, in our view, is essential that the blood clot in the space 10 remains still, in order to avoid the formation of connec ⁇ tive tissue. Many patients have to use removable dentures during the healing process, and if the device is not ver- tically rigid, the load from these dentures may cause the clot to move, thus disturbing it.
  • Fig. 4 shows an embodiment of the inventive device used for recreating or newly creating cheekbone by bone growth.
  • the device comprises a curved, mouldable but vertically rather rigid element of slight thickness.
  • the device 14 has rounded edges in order not t damage surrounding tissue.
  • the device is perforated to enable oxygen and nutrient supply to the blood clot in the space defined by the device.
  • the device is formed with peripheral openings 16 for attachment means, optionally in the form of pins 15 (cf. Fig. 5c), which fix the device in the bone tissue round the area where growth of bone tissue is to be produced.
  • the device is used roughly in the same manner as described above. The area where bone growth is to be pro ⁇ quizd, is uncovered by cutting away the flap.
  • the device which has been shaped so as to correspond to the shape desired for the created bone tissue, is fixed by means of the pins 15 in the existing bone tissue. There ⁇ after, the flap is put in place over the device and sewn on. After about 6 months, bone growth has been achieved in the space beneath the device.
  • Fig. 5a shows an upper jaw from above.
  • the continuous lines illustrate the extension of the existing jawbone, and the broken line illustrates the perforated, self-sup ⁇ porting (rigid) device 14 which keeps out the soft tissue and promotes bone growth in the space 10.
  • Fig. 5b illu ⁇ strates the same jaw, but in profile, and
  • Fig. 5c shows the perforated device from the front.
  • the same reference numerals as before are used. With this device, a much more aesthetical appearance can be obtained. Thus, the lip is pushed out, and the sunken, aged looks of the patient are radically changed. The prosthesis replacing the lost teeth is connected to the underlying mucous membrane in an aesthetical manner.

Abstract

Procédé servant à produire une croissance du tissu osseux chez l'homme ou chez les animaux, et consistant à détacher un lambeau de tissu osseux dans la zone où la croissance doit avoir lieu, une hémorragie étant ainsi provoquée, puis à remettre le lambeau en place à une certaine distance du tissu osseux, un espace pour le sang provenant de l'hémorragie étant ainsi formé entre le lambeau et ledit tissu. Un dispositif permettant de mettre en oeuvre le procédé est constitué d'un matériau inerte et compatible avec le tissu et comporte un élément mince, perforé et bombé ainsi qu'un dispositif de fixation. Un dispositif servant à l'ancrage efficace d'un implant (5) dans du tissu osseux (6) présente la forme d'une calotte perforée (1) dont la périphérie inférieure (2) définit une surface beaucoup plus grande que la superficie de la section de l'implant (5). Par ailleurs, une ouverture (3) est ménagée dans le dispositif afin d'en permettre le montage sur l'implant. On décrit également un procédé permettant l'ancrage solide d'un implant.
