Fig.3 is a so-called longitudinal section (coronal).  It helps us decide the length of the implant.  The socket is long and empty.  So we should place an implant as long as possible.  The implant may have to push the sinus floor (>) upward to gain its length and tight contact with the bone.  According to the measurements, the implant is expected to have 14 or 17 mm long.  We will make final decision for the length and diameter of the implant during surgery. The root #3 is called palatal. Return to original article
