Method for enlarging a jaw bone using a hollow dental implant having a side perforation

Abstract

A system comprising a container and a bone augmentation material and a method of using the system to regenerate bone in the jaws by inserting the container and the bone augmenting material between the jaw bone and periosteal tissue.

What is claimed is: 
     
         1 . A guided bone regeneration system for augmenting bone between the jaw bone and its periosteal tissue to treat human patients in need for enlargement of the jaw bone comprising:
 a device in the shape of a container before being inserted inside the body for insertion between said jaw bone and said periosteal tissue, and a bone augmenting material, a top of said container has towards said periosteal tissue a periosteal-tissue-contacting region which is resistant to epithelial tissue ingrowth, a bottom of said container has towards said jaw bone a bone-contacting region, said bone-contacting region is made at least partially from a bio-dissipative material, said container is filled with said bone augmenting material, said periosteal-tissue-contacting region having a first stiffness and said bone-contacting region having a second stiffness less than said first stiffness.   
     
     
         2 . The system of  claim 1 , wherein at least part of said bone augmenting material is bio-dissipative 
     
     
         3 . The system of  claim 1 , wherein said bone-contacting region, before being inserted inside said body is resistant to the passage of said bone augmenting material from inside said container downwards to beneath said container. 
     
     
         4 . The system of  claim 1 , wherein said bone-contacting region and said periosteal-tissue-contacting region, before being inserted inside said body are substantially horizontal. 
     
     
         5 . The system of  claim 1 , wherein said bone-contacting region, before being inserted inside said body, is perforated, with more than one hole that allow bone tissue ingrowth inside said container. 
     
     
         6 . The system of  claim 1 , wherein said bone-contacting region being configured, before being inserted inside said body, to retain said bone augmenting material within said container. 
     
     
         7 . The system of  claim 1  wherein said bone-contacting region exhibits a first mean time to dispersion and said periosteal-tissue-contacting region exhibits a second mean time to dispersion longer than said first mean time to dispersion. 
     
     
         8 . The system of  claim 1 , wherein said container includes at least one fill opening into which said bone augmenting material may be inserted. 
     
     
         9 . The system of  claim 1 , wherein said bone augmenting material includes rigid particles. 
     
     
         10 . The system of  claim 1 , wherein said container includes an element assisting filing said container with said bone augmenting material. 
     
     
         11 . The system of  claim 1 , wherein said periosteal-tissue-contacting region is made from a guided bone regeneration membrane. 
     
     
         12 . The system of  claim 1 , wherein said container includes an extension for fixation, said extension has at least one hole. 
     
     
         13 . The system of  claim 1 , wherein the most lower area of said container, before being inserted inside said body, is resistant to passage of at least part of said bone augmenting material. 
     
     
         14 . The system of  claim 1 , wherein an aperture which is large enough to allow the passage of all said bone augmenting material through said aperture is absent from said bone contacting region. 
     
     
         15 . The system of  claim 1 , wherein at least part of said container is made from collagen. 
     
     
         16 . The system of  claim 1 , wherein said bone augmenting material is being inside a syringe before being inserted inside said container. 
     
     
         17 . The system of  claim 1 , wherein said system further includes a screw for fixating said container to said jaw bone. 
     
     
         18 . The system of  claim 1 , wherein said system further includes a tack for fixating said container to said jaw bone. 
     
     
         19 . The system of  claim 1 , wherein said system further includes a cannula for insertion of said container adjacent said bone so at least part of said container being inside said cannula before being inserted inside said body. 
     
     
         20 . The system of  claim 1 , wherein said container has a fixating collar along at least part of the borders of said container, said collar has several holes.
