Abstract
Devices and methods for gradual displacing of the soft tissues covering bones. The gap developing between the bone and the displaced soft tissue will be filled with bone callus as it is in distraction osteogenesis. The devices and methods allow formation of bone in distraction osteogenesis without cutting a segment of the bone. The devices and methods are particularly useful in dental implantology for vertical ridge augmentation by displacing the periosteal tissue and for sinus lift by displacing the Schneiderian membrane. The devices and methods can also regenerate soft tissue between the bone and the displaced soft tissue.
Claims73
A method for expanding, stretching, displacing or regenerating tissues comprising:
- (a) inserting at the bone soft tissue interface at least part of a displacing device, said displacing device includes a soft tissue displacer and a displacing element configured to displace said soft tissue displacer from the surface of said bone so as to displace said soft tissue to create a space between said bone and said soft tissue, said device is configured to allow new tissue ingrowth into said space while said soft tissue displacer is between said bone and said soft tissue, said soft tissue displacer includes a protruding element rigidly connected to said soft tissue displacer configured to protrude through said soft tissue;
- (b) displacing said soft tissue displacer from the surface of said bone so as to displace said soft tissue.
A method for expanding, stretching, displacing or regenerating tissues comprising:
- (a) inserting at the bone soft tissue interface at least part of a displacing device comprising a soft tissue displacer, said device is configured after activation to displace said soft tissue displacer from the surface of said bone so as to displace said soft tissue to create a space between said bone and said soft tissue, said device is configured to allow new tissue ingrowth into said space while said soft tissue displacer is between said bone and said soft tissue, without separating said new tissue from said bone, said soft tissue displacer includes a protruding element rigidly connected to said soft tissue displacer configured to protrude through said soft tissue, the height of said device inside the body between said bone and said soft tissue is enlarged as said device is activated
- (b) displacing said soft tissue displacer from the surface of said bone so as to displace said soft tissue.
A device for expanding, stretching, displacing or regenerating tissues comprising:
- a soft tissue displacer for insertion at least partially to the bone soft tissue interface and a displacing element configured to displace upwards said soft tissue displacer in a vertical direction from the surface of said bone so as to displace said soft tissue to create a space between said bone and said soft tissue, said device is configured to allow new tissue ingrowth into said space while said soft tissue displacer is between said bone and said soft tissue, said soft tissue displacer includes a protruding element rigidly connected to said soft tissue displacer configured to protrude through said soft tissue, said soft tissue displacer includes a rigid plate to be located between said bone and said soft tissue, the plane of at least part of said plate being substantially perpendicular to said direction, at least one extension is extending from said part of said plate downwards and horizontally.
