Definitions

  • the present invention relates to a dental implant carrier for mounting in a cavity, in particular a predrilled bore, a bone, with a body insertable into the cavity and a clamping part with an implant post for the attachment of a dental implant.
  • Dental implants as fixed dentures combine many advantages in terms of comfort, dental aesthetics and functionality: the dental implant support is inserted into the jawbone and then grows over time with bone and tissue. There, the dental implant carrier assumes the function of a natural tooth root. The most important prerequisite for a successful placement of an implant carrier is the firm ingrowth into the bone tissue, which is usually done only after a few months. During the time of waxing, the patient receives a provisional tooth system. If the dental implant carrier fused firmly, so the final dentures is fitted.
  • Object of the present invention is to propose a dental implant carrier of the type mentioned, which allows not only an improved fit and an immediate load.

  • the present invention makes now this dense and stable structure of this bone outer layer (Substantia compacta corticalis, hereinafter referred to as Compacta) advantage, by in one step, the body with its spring-trained spreader is inserted into the prepared bore of the jawbone, the laterally projecting and preferably compressible expansion parts are again automatically spread in the radial direction after passing through the opening of the compacta in sponge-like bone tissue. Subsequently, the main body can be pulled with its spread spreading parts through the clamping part to the inside of the stable Compacta towards the implant post.
  • the main body in the unloaded state has at least two spaced-apart areas with different diameters and that the base body is formed in the region of the largest diameter resilient and the spring load of the main body in the region of its largest diameter, preferably radially outwardly.
  • the base body acts, at least in the region of its largest diameter, preferably radially outwards.
  • the base body is formed compressible at least in the region of its largest diameter, so that it can be inserted into the cavity from the outside. It is expedient if the base body is designed such that it together with the clamping part - for example, by a cooperating screw - in the bore of the jawbone! is einf ⁇ hrbar.
  • the spreading parts can be beveled at its upper free end.
  • a chamfer can be formed to the outside of the body.
  • the clamping part above the preferably existing conical section in the radially widened area is followed by a cylindrical area which either has laterally projecting cutting edges or alternatively has a self-tapping thread.
  • a screwing into the jawbone and here in particular in the area of the Compacta is achieved when screwing the clamping part in the area) of the cutting or the self-tapping thread.
  • the upper region of the clamping part is thus designed as a cutting tool, which allows an improved fit when screwing the implant.
