Abstract
A bone spreader for preparing a site for dental prosthesis implantation consists of a relatively flat, wide, blade component and a longitudinal ridge component centrally disposed on one side of the blade component. Penetration of the instrument effects spreading of cortical bone tissue and produces a recess that includes a groove portion within which the root element of a dental implant can be accommodated.
Claims24
An instrument for spreading bone tissue so as to facilitate implant insertion, said instrument having a forward end portion constructed for bone penetration and terminating at a tip, and a rearward end portion constructed for receiving driving force, said instrument being comprised of a relatively wide and thin blade component having a relatively sharp peripheral edge portion, including laterally spaced edge sections and comprising said tip, extending effectively about at least said forward end portion of said instrument, and an integral ridge component extending rearwardly from adjacent said tip on one surface of said blade component, said ridge component having a leading end element, adjacent said tip, that merges with said one surface of said blade component and is formed to facilitate bone penetration.
In a method for bone implant insertion, the steps comprising:
- (a) identifying an implantation site;
- (b) driving an instrument for spreading bone tissue into bone at said site so as to form a recess extending into said bone, said recess having a portion dimensioned and configured for the ready receipt of an implant element;
- (c) removing said instrument from said recess;
- and
- (d) inserting an implant element into said recess, said instrument for spreading bone tissue comprising a forward end portion constructed for bone penetration and terminating at a tip, and a rearward end portion constructed for receiving driving force, said instrument being comprised of a relatively wide and thin blade component having a relatively sharp peripheral edge portion, including laterally spaced edge sections and comprising said tip, extending effectively about at least said forward end portion of said instrument, and an integral, relatively narrow ridge component extending rearwardly from adjacent said tip on one surface of said blade component, said ridge component having a leading end element, adjacent said tip, formed to facilitate bone penetration.
In a method for implant insertion, the steps comprising:
- (a) identifying an implantation site;
- (b) driving an instrument for spreading bone tissue into bone at said site so as to form a recess extending into said bone, said recess being dimensioned and configured for the ready receipt of an implant element;
- (c) removing said instrument from said recess;
- and
- (d) inserting an implant element into said recess, said recess comprising an inwardly tapered plane portion of relatively wide, thin cross section, and a relatively narrow groove portion extending longitudinally along one side of said plane portion, said groove portion cooperating with said plane portion for receiving said implant element.
An instrument for spreading bone tissue so as to facilitate implant insertion, said instrument having a forward end portion constructed for bone penetration and terminating at a tip, and a rearward end portion constructed for receiving driving force, said instrument being comprised of a relatively wide and thin blade component having relatively sharp peripheral edge portion, including laterally spaced edge sections and comprising said tip, extending effectively about at least said forward end portion of said instrument, and an integral ridge component extending rearwardly from adjacent said tip on one surface of said blade component, said ridge component having a leading end element, adjacent said tip, formed to facilitate bone pentration, and at least a forward end portion of said ridge component being of substantially curvilinear cross section.
