Definitions
- the invention relates to a covering membrane made of body-compatible, possibly at least partially resorbable membrane material for temporarily covering a recess in the body's own bone tissue filled with bone building material, in particular hydroxyapatite granules.
- bone building material which is usually made from a mis ⁇ chung from bone substitute material, such as hydroxyapatite granules, and the body's own bone particles, or also from bone substitute material or body's own bone particles alone.
- bone building material which is usually made from a mis ⁇ chung from bone substitute material, such as hydroxyapatite granules, and the body's own bone particles, or also from bone substitute material or body's own bone particles alone.
- EP 0 475 477 discloses a covering membrane of the type described above, in which the covering membrane is essentially completely resorbable, but there is the possibility that the covering membrane is resorbed so quickly that the bony growth of the bone-building material and so that the healing of the bone defect and the lost periodontal tissue or the dental cement can, under unfavorable circumstances, be disturbed by the inflammatory process accompanying any resorption of foreign tissue.
- the US 48 16 339 shows a cover membrane made of several layers, these layers not consisting of resorbable membrane material, but of polytetrafluoroethylene-containing materials.
- the multilayer structure serves to optimize the waxing properties, but the lack of resorption of the membrane material can lead to long-term problems.
- a cover membrane of the gate Described in accordance with the invention, in which the fact that the membrane material can be more quickly absorbed from the side facing away from the body's own bone than from the side facing towards the body's own bone largely ensures that the bony growth of the bone building material and thus the healing of the bone defect essentially undisturbed by the inflammation process accompanying any resorption of foreign tissue.
- the generic cover membrane has proven itself. However, it has turned out to be desirable to give the soft or connective tissue surrounding the bone defect site the possibility of rapidly growing on the covering membrane, so that a good connection between the soft tissue and the bone that is later restored is ensured. This is particularly, but not exclusively, of particular importance if the covering membrane is to remain in the body.
- the invention is based on the object of developing the generic covering membrane in such a way that a flawless stabilizing and relative movement-avoiding connection of the soft tissue surrounding the bone defect site or of the collagen structures that result from the predeterminated granulation tissue, which after bleeding into the bone defect parts this fills, and the cover membrane is guaranteed.
- this object is achieved in that the side of the covering membrane facing the soft tissue and / or the bone tissue (each) has a retention support device for improving the retention of the soft tissue or the (respective) collagen structure (s) on the covering membrane /exhibit.
- the invention also provides for the retention support device (s) to have at least one mechanical retention aid.
- the invention further provides that the mechanically active retention aid (s) is / are at least partially designed for positive engagement by soft tissue and / or collagen structure (s).
- the mechanical retention aid (s) is / are at least partially formed by projections and / or depressions in the covering membrane of the covering device.
- the invention also provides that the mechanical retention aid (s) is / are at least partially formed by uneven surfaces of the covering membrane of the covering device.
- the invention provides that the mechanical retention aids are at least partially formed by a tissue and / or knitted structure of the surface of the covering membrane of the covering device facing the soft tissue or the bone tissue.
- the invention also provides that the retention support devices are / are formed at least partially by appropriate selection of the chemical composition and / or the morphological structure of the material of the covering membrane in the area of the covering membrane facing the soft tissue or the bone tissue.
- the invention is characterized by at least two layers of different structure and / or composition, the layer facing the soft tissue being the Retention support device (s) has / have.
- the invention is also characterized by open micropores provided in the soft tissue and / or the layer facing the bone tissue.
- the invention is characterized by chemically and / or physically acting molecular docking aids for the soft tissue or the collagen structure (s) provided in the area facing the soft tissue and / or the area facing the bone tissue.
- the invention is based on the surprising finding that it is possible to effectively promote the adhesion of the connective or soft tissue or the collagen structures which sprout into the bone defect site by virtue of the fact that the soft or connective tissue or the bone defect parts facing surface of the covering membrane is formed in such a way that retention support devices are provided for improving the growth of the respective tissue or the respective collagen structures, whereby a reliable stabilizing connection with the covering membrane is ensured.
- retention support devices can be, for example, mechanically acting devices for preferably interlocking gripping through soft or connective tissue or collagen structures.
- chemical, ie molecularly acting, docking aids can also be provided, which may be formed by a corresponding special “special layer” of the cover membrane, which, for. B. facing the connective tissue.
- a corresponding special “special layer” of the cover membrane which, for. B. facing the connective tissue.
- the base layer can be designed in such a way that there is a particularly good cell-occlusive and / or mechanically supportive effect.
- FIG. 1 shows a first embodiment of a cover membrane according to the invention in section perpendicular to the membrane plane;
- FIG. 2 in a representation corresponding to FIG. 1, a further exemplary embodiment of a cover membrane according to the invention.
- Fig. 3 shows another embodiment of a
- the surface facing the connective or soft tissue lying at the top of the drawing has a covering membrane 18, projections 36 and depressions 38, which are each designed so that they form through collagen structures of the connective tissue that grows from above ⁇ can be encompassed, whereby the retention of Connective tissue on the cover membrane 18 is improved.
- the covering membrane 18 is constructed from a base layer 40, which faces the bone, and a cover layer 42, the latter having open micropores 44, which are also suitable for the ingrowth of collagen structures.
- the covering membrane 18 has a backing layer 46 on the side of the base layer 40 facing away from the covering layer 42, ie facing the bone defect site, which is also provided with open micropores 44, which are used to ingrow collagen structures from the bone defect site are suitable.
- the layers 42 and 46 preferably have such a resorption genetics that there is a resorption time of about 6 to 12 weeks in periodontal surgery and a resorption time of about 6 to 9 months in bone surgery.
