Definitions

  • the invention relates to a dental implant according to the preamble features of claim 1, a closure cap according to the preamble features of claim 6 and a system according to the preamble features of claim 11.
  • Implants are becoming increasingly important for the replacement of missing teeth. Ideally, implants enable a stable and long-lasting replacement of lost teeth, which also creates a visually appealing impression, which is particularly important in the anterior region.
  • the interdental papillae represent a still serious problem when replacing several successive teeth by means of implants. Due to the breakdown of the jaw bone, which usually precedes tooth loss, the alveolar ridge is changed so that the interdental papillae are no longer formed naturally. The increase in bone required for the formation of the interdental papilla is consequently lost. Missing interdental papillae, however, create an optically unappealing impression. There are gaps between the teeth, which is why they are referred to as "black triangles".
  • interdental papillae not only has optical disadvantages, it also lacks the natural function of the interdental papillae. These are usually used to keep the interdental spaces clear of food residues, which reduces inflammation of the gums.
  • Dental implants usually consist of a generally cylindrical base body.
  • An implant has an upper end that protrudes somewhat from the bone (distant from the jaw) and a lower, apical end that is anchored in the bone (near the jaw). With the The lower end of the implant is inserted into the jawbone.
  • implants known, for example with an external thread, with openings in the vicinity of the lower end for growing through the bone, with a convex or flat lower end, with a polished outer surface or a roughened outer surface, etc.
  • all known implant shapes have an essentially flat, upper end. At best, deviations are known to the effect that structures are formed on the upper end, which can be engaged, for example, with an appropriate screwing device in order to drive the implant into the jawbone.
  • DE 197 25 788 AI describes a support structure for a membrane for the controlled regeneration of periodontal tissue.
  • the supporting framework is inserted between the implants and covered with a membrane, which creates a space in which tissue grows.
  • this scaffold does not create proximal bones for an interdental papilla, but only connective tissue is built up.
  • a dental papilla implant is described in US Pat. No. 6,213,774 B1. It has a shaft that can be inserted into the jawbone and a head that is later covered by the gums and thus creates the interdental papilla. The implant remains in the bone.
  • a disadvantage here is that the head of the implant is disruptive to the patient and, moreover, it is sensitive to pressure. Furthermore, the use of a of such papilla implants, of course, that there is jaw bone into which the implant can be inserted. However, a very strongly atrophied jaw bone does not allow the use of such a papilla implant.
  • it is known in the prior art for example, to take connective tissue from the palate and to bring it into a shape that approximately corresponds to a dental papilla. The ball of connective tissue formed in this way is then sutured with gums and in this way also forms an artificial interdental papilla.
  • the implant After placing the implants, it takes a long time for the implant to grow completely and firmly into the bone. During this period, the implant must not be exposed to any loads, which is why the denture cannot yet be attached to the implant.
  • the upper end of the implant is closed with a sealing cap to prevent ingrowth of To prevent gum tissue in the implant.
  • This cap is inserted into the hole in the center of the implant and fixed in it. Then the cap is surrounded by gum tissue, which is sewn over the cap. After the implant has healed, the gums are opened again, the closure cap is removed and the dentures are inserted. Since the generally customary caps are intended to protect the implant from ingrowth with gums and epithelial tissue, the caps accordingly have the diameter of the implant.
  • closure caps are known, the edge of which protrudes beyond the dental implant, thereby preventing cells from migrating into the peri-implant space at the passage point from the soft tissue area. This means that the immediate area around the implant should be protected against the immigration of epithelial cells. With the closure caps known from these documents, however, only the immediate vicinity of the implant covered with them can be covered.
  • the dental implant according to the invention is an essentially cylindrical body which has an upper and a lower end.
  • a receptacle in particular an inner bore with a hexagon socket or anti-rotation protection, is provided for receiving, in particular, a closure cap or a denture carrier.
  • the expression "essentially cylindrical” denotes a body that is both a strictly cylindrical Can have shape, as well as deviations thereof, for example in the form of a truncated cone.
  • the body of the dental implant can have any shape known from the prior art;
  • the lower end near the jaw can be both convex and flat, threaded holes can be provided along the circumference of the body, ie on its lateral surface, the surface can be polished or roughened, for example sandblasted or etched, and there can also be recesses be provided in which the bone can grow.
  • the upper end of the dental implant is deepened, in particular designed to be concave. In other words, the upper end is saddle-shaped. This means that the upper, near the jaw surface or the top of the dental implant is not designed flat, as is known from the prior art, but that a rounded incision, a recess is provided.
  • the recessed, upper end of the dental implant can be both trough-shaped and spherically concave, or can have a similar design. Furthermore, the depression can be both symmetrical and non-symmetrical with respect to an axis passing through the center of the implant.
  • the concave upper end can deviate from a flat surface at its deepest point, in particular in the range from 0.1 mm to 10 mm.
  • the recessed, saddle-shaped shape of the upper end can also be described using points that are located on an edge of the upper end.
  • the area that is located at the transition between the upper surface of the upper end and the outer surface of the cylindrical body is regarded as the edge.
  • This edge is all-round and points can be defined there at an even distance, with a top view similar to the quarter hours of a clock.
  • These four points are at a certain distance from the lower end of the dental implant. According to the invention it is now provided that the first and third points are further away from the lower end than the second and fourth points, which are approximately at right angles to the Connection line of the first / third point are arranged.
  • the first and third points and the second and fourth points are preferably each equidistant from the lower end, ie the distance between the first and third points and that of the second and fourth points from the lower end is identical. Furthermore, it is preferably provided that the distance of the first and third points from the lower end corresponds to the total height of the dental implant.
  • the dental implant When the dental implant is inserted into the jawbone, the dental implant is arranged so that the raised parts of the dental implant come to rest on the dental arch, whereas the lower parts are arranged vestibularly and orally.
  • the edge of the dental implant used reflects the natural, garland-shaped course of the alveolar ridge. This becomes particularly clear when several dental implants are placed side by side.
  • the jawbone can keep its natural shape or regenerate accordingly between the two dental implants located next to one another.
  • proximal bone is broken down.
  • this remains because it does not protrude beyond the upper end of the dental implant, but rather corresponds to its height.
  • a space is also created for the regeneration of already degraded, proximal bone in which the bone material can grow.
  • a plastic membrane known from the prior art, in particular from
  • Polytetrafluoroethylene can be stretched over the dental implants, creating a storage space into which bone material can grow.
  • the dental implant would correspond to the root and the denture to the crown.
  • the boundary between the root cement that surrounds the root and the tooth enamel that surrounds the crown is curved, i.e. not in a straight line.
  • the boundary between the dental implant and dentures is not exactly as in the prior art, but rather curved. This also contributes to the natural formation of papillae, which exactly reflect this curved boundary between tooth enamel and root cement.
  • the closure cap according to the invention is intended in particular for the dental implant according to the invention.
  • the closure cap can be fixed in the inner bore of the dental implant by means of, for example, a screw. It covers the dental implant and thus prevents the ingrowth of gums on the top of the dental implant, in accordance with the closure caps known from the prior art. It is envisaged that the closure cap will protrude beyond the edge of the dental implant. In other words, the closure cap is wider or larger in diameter than the dental implant. This creates a reserve space in the vicinity of the dental implant into which bone can grow. This means that the closure cap not only keeps the dental implant free of gums and epithelial tissue, but also the bones surrounding the dental implant.
  • the closure cap is elongated, namely that the cap is wider along the course of the dental arch than in the vestibular-oral direction.
  • This configuration according to the invention enables two adjacent caps to overlap. That way created by a number of caps a relatively large reserve space in which bone material can grow.
  • the closure cap since the closure cap also protrudes vestibularly and orally beyond the edge of the dental implant, not only interimplant but also circular bone around the dental implant can be obtained with the closure cap according to the invention.
  • the closure cap according to the invention is designed so that it can be fixed in the implant regardless of the angle. In other words, it is designed to be rotatable. An arrangement of the closure cap according to the physiological course of the dental arch is thus possible at any point. Furthermore, the closure cap is designed so that adjacent closure caps overlap without being formed between these gaps, into which connective tissue could grow, for example. For this purpose, the edge regions of the closure cap preferably have the shape of spherical segments. Another advantage of the closure cap according to the invention is that it is a prefabricated closure cap which can be produced in series without the need for a one-off production. This enables relatively inexpensive production.
  • the system according to the invention for the regeneration of proximal jaw bone consists of a dental implant according to the invention and a closure cap according to the invention.
  • the protruding edge of the closure cap covers the adjacent jawbone and thus provides a space in which the jawbone can grow.
  • adjacent caps overlap one another in the dental arch. This creates a gapless storage space for the ingrowth of the bone.
  • the use of both a prefabricated cap and A made-up dental implant in the system according to the invention has the advantage that a very inexpensive method is made available, with the help of which degenerated bone tissue can be rebuilt, and thus interdental papillae can be created.
