Condensing skeletal implant that facilitate insertions

Abstract

A dental implant that facilitates insertion includes a body having a coronal end and an apical end opposite the coronal end. An implant-prosthetic interface region is provided adjacent the coronal end. A tapered region is adjacent the apical end. A variable profile helical thread extends along the tapered region. The thread becomes broader in the apical-coronal direction and higher in the coronal-apical direction. The threads include an apical side, a coronal side and a lateral edge connecting them. The variable profile thread includes an expanding length of the lateral edge while the distance of the lateral edge from the base is reduced in the direction of the coronal end. The implant also has a gradual compressing tapered core, a self drilling apical end with a spiral tap, and a coronal end with and inverse tapering.

1 . A dental implant comprising:
 a body;   a coronal region of the body;   an apical region of the body, the apical region having a core with a tapered region wherein a diameter at an apical end of the core is smaller than a diameter at a coronal end of the core; and   a helical thread extending along at least a portion of the apical region;   wherein the apical end of the core is substantially flat and wherein the thread comprises an apical side, a coronal side, and a lateral edge connecting the apical side and the coronal side, a base connecting the thread to the tapered core, a thread height defined between the lateral edge and the base, the lateral edge having a variable width that is expanded along a segment in the direction of the coronal end, so that a least width of the lateral edge of the thread is adjacent the apical end and a greatest width of the lateral edge of the thread is adjacent the coronal end, and the thread having a variable height that is expanded substantially along the segment of the implant in the direction of the apical end, so that a least height of the thread is adjacent the coronal end and a greatest height at apical portion of the thread.   
   
   
       2 . The implant of  claim 1 , wherein the thread extends to an edge of the apical end of the body. 
   
   
       3 . The implant of  claim 1 , wherein the thread adjacent the apical end is self-tapping. 
   
   
       4 . The implant of  claim 1 , wherein the apical end includes a spiral tap, the spiral tap extends from one side of the implant to the opposite side along more than a third of the length of the implant. 
   
   
       5 . The implant of  claim 1 , wherein the implant has more than one thread. 
   
   
       6 . The implant of  claim 1 , wherein the implant includes a protruding element configured to protrude through the gums to allow the connection to a dental prosthesis. 
   
   
       7 . The implant of  claim 6 , wherein the protruding element and the implant are one piece. 
   
   
       8 . The implant of  claim 6 , wherein the protruding element is configured to be attached to an abutment from the side. 
   
   
       9 . The implant of  claim 1 , wherein the an apical end of the thread begins at the substantially flat apical end of the core and the apical end of the thread has a thread height that is greater than the thread height at the coronal end of the thread. 
   
   
       10 . A dental implant comprising:
 a body;   a coronal region of the body;   an apical region of the body, the apical region having a core with a tapered region wherein a diameter at an apical end of the core is smaller than a diameter at a coronal end of the core; and   a helical thread extending along at least a portion of the apical region;   wherein the apical end of the core is substantially flat and wherein the thread comprises an apical side, a coronal side, and a lateral edge connecting the apical side and the coronal side, a base connecting the thread to the core, a thread height defined between the lateral edge and the base, the thread having a variable height that is expanded substantially along the segment of the implant in the direction of the apical end, so that a least height of the thread is adjacent the coronal end and a greatest height at apical portion of the thread, and wherein the an apical end of the thread begins at the substantially flat apical end of the core and the apical end of the thread has a thread height that is greater than the thread height at the coronal end of the thread   
   
   
       11 . The implant of  claim 10 , wherein the coronal region of the body has a frustoconical shape wherein a diameter of an apical end of the coronal region is larger than a diameter of a coronal end of the coronal region.
