Precision dental implant system
View Patent ↗The present dental implant, whether tapered or cylindrical, is cannulated, to allow placement over a slender post pre-embedded into the host bone. The post is a rigid, not a flexible, construct that can be placed accurately, as to position and angle, in the jawbone. With the post in the correct position, the implant is then installed directly over the temporarily anchored post, and after tightening of the implant by rotation the post is removed.
1 . A dental implant system comprising:
a dental implant;
a removable position implant explorer, comprising a slender post having a post shaft and a post distal cutting tip that tapers distally to a sharp point and contains threads proximally adjacent to said post distal cutting tip,
wherein said slender post has a constant diameter from its proximal end to said threads and further is configured to engage to a driver tool at its proximal end and also is configured to contact the jawbone at its distal end as a pre-drill configured for insertion and removal, thereby facilitating the position and orientation of said dental implant during implantation;
further wherein said dental implant has a single cannulation therein, wherein said cannulation extends the entire length of said dental implant as a cannulated shaft, wherein said cannulated shaft is configured to receive said position implant explorer throughout the entire length of said cannulated shaft throughout said single cannulation which extends the entire length of said dental implant,
said dental implant having an exterior diameter and further comprising an outer shaft having a shaft end bearing cutting threads on the exterior thereof, said outer shaft having a distal shaft and a proximal shaft, said cutting threads having a chamfer, wherein said proximal shaft has a proximal collar having a proximal collar recess and further wherein said cutting threads end with said chamfer groove at a shaft tip;
and further wherein said cannulated shaft extends from said proximal collar to and through said shaft tip and further wherein said cannulated shaft surrounds throughout its length said removable position implant explorer;
an abutment containing an abutment cannulation configured to engage a coronal portion of and to attach to said dental implant with a set screw that fills said abutment cannulation upon affixation of said abutment and said set screw, with said set screw being configured to hold said abutment in place on said coronal portion of said dental implant, wherein said slender post of said position implant explorer has a diameter of ⅓ to ⅕ of said external diameter of said dental implant; and wherein upon positioning of said position implant explorer and said dental implant, said dental implant adopts the same orientation as said position implant explorer.
2 . The dental implant system of claim 1 , wherein said cannulated shaft has interior cannulation threads on a segment of an inner surface of said cannulated shaft.
3 . The dental implant system of claim 2 , wherein said set screw bears threads which mate with said interior cannulation threads.
4 . The dental implant system of claim 2 wherein said set screw has a distal end sized to mate with and partially or totally fill a distal end of said cannulated shaft.
5 . The dental implant system of claim 2 , wherein said abutment fits via an abutment anchor into said proximal collar recess and said set screw secures said abutment to said implant.
6 . The dental implant system of claim 2 , wherein said proximal shaft has a proximal end and said proximal end is shaped to mate with conventional dental hand pieces either directly or through an adapter to conform to dental hand pieces.
7 . The dental implant system of claim 2 , further wherein said abutment comprises a cannulated abutment and said set screw comprises a threaded set screw.
