Dental bridge attachment system and method

Abstract

Provided is a removable bridge system for attachment to a plurality of dental implants, including a plurality of abutments, each including a seat portion conforming with a shape of a corresponding implant head and allowing fixedly positioning of the abutment to the implant, and an abutment head. At least one of the abutments is configured as a locking abutment and includes a locking portion. A bridge generally conforming with dental parameters of the individual has a bottom surface formed with a receiving apertures shaped so as to snugly fit over a corresponding abutment head. The bridge further includes a locking arrangement for removably locking the bridge to the abutments, and including one or more locks for detachable locking to a respective at least one locking abutment.

         28 . An adapter abutment to be received between a dental implant head and a seat portion of an abutment, the adapter abutment, comprising:
 an adapter seat portion configured for motionless fixation over said dental implant head and defining an adapter seat portion axis;   an adapter head portion configured for motionlessly affixing thereto a seat portion of said abutment, and defining an adapter head portion axis; and   an adapter abutment body portion extending between said adapter seat portion and said adapter head portion.   
     
     
         29 . The adapter abutment according to  claim 28 , wherein the adapter seat portion axis and the adapter head portion axis extend at any position respective to one another, coextending, parallel or intersecting one another. 
     
     
         30 . The adapter abutment according to  claim 28 , wherein the adapter abutment body portion extend coaxially with any one of the adapter seat portion and the adapter head portion. 
     
     
         31 . The adapter abutment according to  claim 28 , wherein one or more of the adapter seat portion and the adapter head portion are of any regular or irregular shape. 
     
     
         32 . The adapter abutment according to  claim 28 , wherein one or more of the adapter seat portion and the adapter head portion configure as either a male-type coupler or a female-type coupler, configured for fixedly coupling engagement, at fixed angular orientation, with respect to a dental implant head and a seat portion of an abutment, respectively. 
     
     
         33 . The adapter abutment according to  claim 28 , configured for securing directly over the head of the dental implant, by a fastener screw. 
     
     
         34 . The adapter abutment according to  claim 28 , configured for securing directly over the adapter head portion of an abutment, by a fastener screw. 
     
     
         35 . The adapter abutment according to  claim 28 , comprising a locking portion configured for locking engagement with a locking arrangement of a dental bridge. 
     
     
         36 . The adapter abutment according to  claim 28 , comprising a througoing bore coaxial with the adapter seat portion axis, and a threaded bore extending along the adapter head portion axis. 
     
     
         37 . The adapter abutment according to  claim 36 , wherein said througoing bore has a seat opening at a side wall portion of the adapter abutment and an opening at the adapter seat portion.
