Multi-adjustable drill guide for dental prosthesis

Abstract

In one aspect, a group of prefabricated components to form a drill guide system for drilling a properly spaced and oriented implant hole adjacent to another implant hole or adjacent to a fully-installed implant is disclosed. In another aspect, improved procedures for drilling a dental implant hole adjacent to another implant hole are disclosed.

1 . A system of prefabricated components for forming a drill guide, comprising: 
 a positioning assembly;    a connective member; and    a drill sleeve.    
   
   
       2 . The system of  claim 1  wherein said positioning assembly comprises a paralleling pin disposed through a positioning sleeve.  
   
   
       3 . The system of  claim 1  wherein said positioning assembly comprises an implant with a collar connected thereto.  
   
   
       4 . The system of  claim 1  wherein said drill sleeve includes a receiving slot, and wherein said connective member includes an enlarged end portion retained within said slot, said connective member disposed between said positioning assembly and said drill sleeve.  
   
   
       5 . The system of  claim 2  wherein said positioning sleeve and said drill sleeve each include an outer surface and a channel for capturing an end of said connective member, said channel extending from said outer surface into the interior of said sleeve and being more narrow at said outer surface than at said interior so as to form a capture for said end of said connective member.  
   
   
       6 . A method of drilling a dental implant hole adjacent a first implant hole comprising: 
 disposing a positioning assembly in the first implant hole;    connecting the positioning assembly to a drill sleeve; and    drilling the dental implant hole through the drill sleeve.    
   
   
       7 . The method of  claim 6  wherein disposing a positioning assembly in the first implant hole comprises disposing a paralleling pin through a positioning sleeve and into the first implant hole.  
   
   
       8 . The method of  claim 6  wherein disposing a positioning assembly in the first implant hole comprises disposing an implant having a framework component connected thereto in the first implant hole.  
   
   
       9 . The method of  claim 6  wherein connecting the positioning assembly to a drill sleeve comprises disposing a bar portion between the positioning assembly and drill sleeve.
