Screw or Tapered Implant?

Figure on the left is a 3-D image showing that the socket of the second molar is tapered.  Figure on the right is a sagittal section through the msiodistal aspect of the tooth #15.  The apical dimension is less than 5 mm, smaller than the apical diameter of 8x11 mm tapered implant (5.5 mm).  Furthermore, can we lift the sinus floor to gain apical friction and use 8x14 mm tapered implant?  Return to main article
