Manual driver for implant drills and method of dental implantation

Abstract

A manual driver for a dental implant drill or other dental implant tools and the method of use for preparing for dental implantation are provided. The manual driver includes a handle, an extension shank and a chuck having an axial channel configured to receive and interlock an implant drill, and a fastening screw transverse to the axial channel. The method of manual preparation for dental implantation using the manual driver has a high precision, and reduces the risk of bone cracking caused by vibration of motor-driven drilling. The manual drilling method provides better tactile sensation and drilling control to the dentist. Further, the method avoids drilling irrigation, allows collection of virgin bone tissue from the drills, and reintroduces the collected bone tissue in the receiving bore to promote bone regeneration after the implantation.

1 . A manual driver for an implant drill or a dental implant tool comprising:
 (a) a chuck having an axial channel with an opening at a distal end of said chuck and a stop in a proximal portion of said chuck, and a fastening screw transverse to said axial channel adjacent to said stop, said axial channel including an abutment portion for interlocking with a shaft of said implant drill;   (b) an extension shank integral with and extending from said proximal portion of said chuck along a longitudinal axis of said manual driver; and   (c) a handle extending from a proximal end of said extension shank along said longitudinal axis.   
   
   
       2 . The manual driver of  claim 1 , wherein said proximal portion of said chuck is generally cylindrical and a distal portion of said chuck is conical tapering toward said distal end. 
   
   
       3 . The manual driver of  claim 2 , wherein said proximal portion of said chuck includes a cut-out having a planar surface in parallel with said longitudinal axis of said driver, said cut-out rendering visible a proximal portion of said shaft of said implant drill when said shaft is secured to said dental driver. 
   
   
       4 . The manual driver of  claim 1 , wherein said proximal portion of said chuck includes a threaded transverse bore disposed at said abutment portion of said axial channel for receiving said fastening screw. 
   
   
       5 . The manual driver of  claim 4 , wherein said threaded transverse bore has a recess at an outmost end thereof, adjacent to a periphery of said proximal portion of said chuck, and said fastening screw has an enlarged screw head disposed within said recess of said threaded transverse bore. 
   
   
       6 . The manual driver of  claim 4 , wherein said fastening screw is an Allen head screw. 
   
   
       7 . The manual driver of  claim 4 , wherein said fastening screw has an enlarged screw head disposed outside of said threaded transverse bore. 
   
   
       8 . The manual driver of  claim 1 , wherein said handle is tapered toward said extension shank, providing an ergonomic shape for engagement with hands.
