5. A dental tool adapted to engage, carry, and drive a dental implant, the driving tool comprising:
an elongated shaft having proximal and distal ends;
a housing located at the distal end;
a locking member and a biasing member located in the housing for biasing the locking member against a surface of the implant to hold and carry the implant;
wherein the locking member is formed of a ceramic and the biasing member is formed of a corrosive resistant metal.
6. The dental tool of claim 5 in which the locking member is formed of ruby or silicone nitride.
7. The dental driving tool of claim 6 in which the biasing member is formed of titanium.
8. The dental driving tool of claim 7 in which the distal end has a polygonal shape adapted to engage and drive the implant into a jawbone.
9. The dental driving tool of claim 8 in which the locking member and biasing member hold the dental implant with a removal force between one ounce and 1½ pounds.
10. A dental tool, comprising:
a shaft having a distal end and a proximal end;
a drive mechanism located at the distal end, wherein the drive mechanism is adapted to drive a dental implant into a jawbone;
a retention mechanism located at the distal end and including a housing, a locking member, and a biasing member biasing the locking member, wherein the locking member and biasing member are located in the housing and adapted to hold the dental implant; and
wherein the locking member is formed of ceramic as one of a ball, pin, or cylinder;
and the biasing member is a spring formed of a corrosive resistant material.
11. The dental tool of claim 10 in which the housing includes an axial bore that is perpendicular to a longitudinal axis that extends through the shaft.
12. The dental driving tool of claim 11 in which the locking member and biasing member are removable from the housing.
13. The dental driving tool of claim 12 in which the drive mechanism has a polygonal configuration that matches a polygonal configuration at a coronal end of the implant.
14. The dental driving tool of claim 11 in which the locking member slideably moves in the axial bore.
15. The dental driving tool of claim 14 in which the locking member partially protrudes from the axial bore and engages a surface of the dental implant.
16. A dental tool, comprising:
a shaft having a distal end and a proximal end, wherein the distal end is adapted to drive a dental implant into a jawbone;
a retention mechanism located at the distal end and including a ball and spring biasing the ball, wherein the retention mechanism is adapted to hold and carry the dental implant;
wherein the ball and spring are housed in an axial bore, and the spring biases the ball against an internal cavity of the dental implant; and
wherein the ball is formed of ruby and the spring is formed of titanium.
17. The dental tool of claim 16 wherein the retention mechanism holds the dental implant with a force of about one ounce to 1½ pounds.
18. The dental tool of claim 16 wherein the distal end is shaped as one of a hexagon, star, triangle, square, or octagon.
19. The dental tool of claim 16 wherein the ball and spring are housed in an axial bore;
the spring biases the ball against an internal cavity of the dental implant; and
the distal end has a polygonal shape adapted to engage and drive the implant into a jawbone.
20. A dental tool adapted to engage, carry, and drive a dental implant, the driving tool comprising:
an elongated shaft having proximal and distal ends:
a housing located at the distal end;
a locking member and a biasing member located in the housing for biasing the locking member against a surface of the implant to hold and carry the implant;
wherein the locking member is formed of ruby and the biasing member is formed of titanium.
21. The dental tool of claim 20 wherein the distal end has a polygonal shape adapted to engage and drive the implant into a jawbone.
22. The dental tool of claim 20 wherein the distal end has a polygonal shape adapted to engage and drive the implant into a jawbone and the retention mechanism holds the dental implant with a force of about one ounce to 1½ pounds.
23. The dental tool of claim 20 wherein the locking member and biasing member are housed in an axial bore, and the biasing member biases the locking member against an internal cavity of the dental implant.
24. A dental tool, comprising:
