Definitions

  • the invention relates to a device for spreading a jawbone according to the protection claim. 1

  • Implants are currently produced regelffleBig of titanium, are designed in two parts and comprise a substantially cylindrical basic body which is provided with an external thread for screwing into the jaw and having a central threaded bore for receiving one threaded bolt, by means of which an implant post, in professional circles as n Abutment a designated, is attached.
  • an implant post in professional circles as n Abutment a designated, is attached.
  • the implant In order to be able to screw the essentially cylindrical base body, the implant, into the jaw, it is necessary to have an entire width of the jaw in order to ensure a sufficient hold of the implant in the jawbone.
  • the ridge has a sufficient width so that either m 'rt Anlagen so-called bone replacement materials can be built up until the required thickness is reached Alternatively, it is also possible to spread the jaw bone. In this case, a gap is introduced in the jawbone, which is subsequently widened with a pair of pliers or a spreader hook.
  • a disadvantage of the known in the prior art tools for spreading the jawbone is that they are cumbersome to handle and beyond limit the operating room. When re-drilling for the deep-seated implant stems as well as for the thread cutting it can also lead to unwanted bone removal on the splayed walls. Furthermore, uncontrollable fractures can occur. Also, a "collapse" of the surgical procedure can occur, which can lead to far-reaching complications.
  • the invention aims to remedy this situation.

  • the spreading elements are linearly displaceable to each other.
  • the spreading elements are each formed by two domes that receive a keel leaf, wherein at least two oppositely arranged domes of the spreading elements are connected to each other via a telescopic rod.

  • the keel blades are used to homogenize the adjacent forces and the retention of jaw material. Between the keel leaves, a freely accessible surgical field is ensured. Keel leaves and dome are also conceivable in unwound form, whereby the main pressure during spreading of the upper narrow alveolar crest can be moved even further to the jaw base.
