Abstract
The invention relates to a transcutaneous or transgingival implant having a body 1 made of a bioinert material, whose subcutaneous or subgingival part 2 is anchored in bone tissue, and, in the region of the passage of the body 1 through the skin or mucosa 4, a ring 5 having at least a surface layer, which is contacted by the skin or mucosa, of a bioactive material. Bioinert materials such as titanium or dense, high-purity Al2O3-ceramic material permit good integration of the implant body with bone. The mechanical properties of these bioinert materials also permit their use for load-transmitting functions. Bioactive materials, such as hydroxyapatite ceramics or tricalcium phosphate ceramics, permit a more favourable deposition of tissue at the passage through the skin but their mechanical strength is too low. By providing the ring 5 of bioactive material on a semi-implant of bioinert material in the region of the passage of the implant through the skin or mucosa it is possible to utilise the more favourable tissue compatibility even for load-transmitting transcutaneous or transgingival implants. <IMAGE>
Description
SPECIFICATION
Improvements in and relating to semi-implants
The invention relates to a transcutaneous or transgingival implant made of a bioinert material, whose subcutaneous or subgingival part is anchored in bone tissue.
Transcutaneous implants of the above mentioned type are disclosed, for example, in an article by T.
Albrektsson, P.-l. Branemark and J. Lindström entitled "Transcutaneous titanium implants in clinical practice", in A.J.C. Lee, T. Albrektsson, P.-i. Branemark (editors) "Clinical applications of biomaterials", volume 4 of Advances in Biomaterials, John
Wiley & Sons, Chichester, 1982, pages 157-166.
Transgingival implants of the above mentioned type are known from, for example, an article by P.-l.
Branemark, R. Adell, T. Albrektsson, G. Carlsson, T.
Haraldson, U. Lekholm, L. Lindquist, J. Lindstrom, S.
Lundqvist and B. Rockler entitled "Osseointegrated titanium implants in the rehabilitation of the edentulous patient", in the above book, at pages 133-139. In the above two implant types, the bioinert material is composed of titanium. There are also implants of the above mentioned type in which the bioinert material is composed of a dense, high-strength alumina ceramic material. Implants of this type have been described in, for example, German Patent Specifications Nos. 2,549,114 and 2,619,650. It is common to all these implants that the inert material of which they are composed is the same, even in the region of the passage through the skin or the mucosa, as that from which the whole implant is fabricated.
In general and herein, a bioinert material is to be understood to be a material which, in a biological medium, does not release any ions into the surrounding tissue, or, taking account of the ions which possibly go into solution, only releases ions which do not biochemically interfere with the normal metabolisum of the surrounding tissue. According to present-day knowledge, this certainly applies to the two materials mentioned above, titanium and alumina ceramic material.
The very inertness, described above, of the materials makes deposition of skin or mucosa on the particular implant surface possible, and this ensures an essentially bacteria-tight closure. Nevertheless, according to the present state of knowledge, this takes the form of pure deposition, without biochemical bonding taking place between the bioinert material and the particular tissue in the region of the passage of the implant through the skin or mucosa.
To date, biochemical binding of this type has been observed with materials for which the term "bioactive" has been adopted. These bioactive materials cause the surrounding tissue, in a manner which has not yet been elucidated in every detail, to adhere to the surface of the bioactive material, and this might be termed biochemical binding. Thus, for example, it has been observed in the case of bioinert materials that collagen fibre structures arrange themselves parallel to the surface of the material, while it has been reported in respect of bioactive materials that the collagen fibres may start from the implant surface and, from there, penetrate into the surrounding tissue. Thus both the mechanical adhesion of the skin or mucosa and the bacteria-tight closure at the surface of bioactive materials of this type are more favourable than with the bioinert materials hitherto used.
The bioactive materials hitherto known are hydroxyapatite ceramics, tricalcium phosphate ceramics, glasses containing calcium phosphate, and glass ceramics containing calcium phosphate. It is common to all these materials that their mechanical strength is low. According to present day knowledge, it is in the region of 100 N/mm2 or below for all the materials mentioned. This is too low for load-transmitting implants. An additional factor is that these materials show a great reduction in mechanical strength under load in a biological medium. This fatigue of the materials makes it virtually impossible to use them for loadtransmitting implants.
According to the present invention there is provided a transcutaneous ortransgingival implant comprising a body made of bioinert material, having a subcutaneous or subgingival part which is to be anchored in bone tissue, and in the region of the passage of the body through the skin or gingiva, an annular portion which is composed, at least on its surface of a bioactive material.
The annular portion preferably comprises a ring which is received on the body of the implant. The interface between the body of the implant and the ring may be cylindrical or conical. The ring may be formed as two half shells or elements which may be fixed to the body of the implant by a bioinert adhesive.
An intermediate member, made of a synthetic material which is tolerated by the body, may be inserted between the subcutaneous or subgingival end of the ring and an adjoining part of the body of the implant. The intermediate member may be made of a polymerisable material and may be completely polymerised when in position on the body of the implant.
The supracutaneous or supragingival region of the ring may be rounded off.
The ring may be made wholly of dense hydroxyapatite, ortricalcium phosphate, or a glass, or a glass ceramic material, containing calcium phosphate or may be made of a composite of a metallic foundation and a surface layer of hydroxyapatite or tricalcium phosphate, or a glass, or a glass ceramic material, containing calcium phosphate.
The body of the implant may be made of titanium or alumina ceramic material.
Embodiments according to the invention will now be described by way of example only, with reference to the accompanying drawings, in which:
Figure lisa section through part of an embodiment of a semi-implant according to the present invention; and
Figure 2 is a section similar to that of Figure 1 through another embodiment according to the present invention.
In Figure 1 there is shown the upper end of a body 1 of an implant which has a part 2, which projects into the bone tissue and only the upper portions of which is shown in Figure 1, and a central bore 3 in the supracutaneous or supragingival end of the implant which projects out of the body. The bore 3 serves to receive, for example, the device above in the case of dental implants, or other parts which are to be fixed to the implant for medical reasons. The skin or mucosa of the body is shown at 4. In the region of the passage of the body 1 through the skin or mucosa, the body 1 is reduced in transverse dimensions to provide a step in which a ring 5 is located, the surface of the ring 5 being, in use, in contact with the skin or mucosa. Preferably the surface of the ring 5 forms a continuation of the surface of the adjacent subcutaneous or submucosal part of the body 1.The interface 6 between the ring 5 and the body 1 of the implant is as shown cylindrical.
Figure 2 shows another embodiment of the invention. In Figure 2, only the uppermost part of the body 1 of the implant is shown. Like parts have been designated by the same reference numerals as are used in Figure 1. In this embodiment, between the subcutaneous or subgingival end 7 of the ring 5 and the adjoining face 8 of the body 1, an annular intermediate member 9 made of a synthetic material tolerated by the body is located. Member 9 is made, for example, of a silicone material which is tolerated by the body. Member 9 may be put in place in the form of a ring before the ring 5 is pushed into position from the upper end of the body 1. Alternatively, the synthetic material of the ring 9 may also be introduced into the region above face 8 before it is finally cured. Then the ring 5 is pushed onto the ring 9, which can then cure, in the case of cold polymerisation.In the case of heat polymerisation, the entire body of the implant, together with the ring 9 of synthetic material and the ring 5, may be subjected to appropriate heat treatment in an oven.
In this embodiment the supracutaneous or supramucosal end portion 10 of the ring 5 is rounded off.
In the above embodiments while, as shown, the interface 6 between the body 1 and the ring 5 is cylindrical, it may alternatively be conical. The ring 5 may be fixed to the body 1 by a bioinert adhesive and, to facilitate assembly, may be made as two half-rings.
The rings 5 of the above embodiments are made with at least a layer of a bioactive material on the surface contacted by the skin or mucosa. For examplethe rings 5 may be made wholly of dense hydroxyapatite, or tricalcium phosphate, or glass containing calcium phosphate, or a glass ceramic containing calcium phosphate, or the rings 5 may be made as a composite comprising a metallic body or foundation with a surface layer, on the surface to be contacted by the skin or mucosa, of dense hydroxyapatite, tricalcium phosphate, a glass containing calcium phosphate, or a glass ceramic containing calcium phosphate. Each body 1 is made of a bioinert material, such as titanium or a suitable alumina ceramic material, which is selected to have mechanical characteristics appropriate for the function of the implant.
There are thus provided semi-implants which utilise the favourable properties of bioactive materials in respect of the production of a strong bond of the implant to skin or mucosal tissue in the region of the passage of the implant through the skin or mucosa, but are otherwise made of bioinert materials having the mechanical strength and the resistance to fatigue which are necessary for the intended use.
