Claim 9:
10. A method of performing a sinus lift procedure on a patient, the method comprising:
accessing the maxillary bone of the patient at a location where a dental implant is to be installed;
defining a bore at the location beneath the patient's maxillary sinus;
using an osteotome, fracturing the maxillary bone remaining at a distal end of the bore;
elevating the Schneiderian membrane relative to an inferior surface of the maxillary sinus to define a pocket above the location;
using a surgical instrument, pushing bone graft material into the pocket laterally and superiorly of the bore;
wherein the surgical instrument comprises:
a shank having a body portion, a first end, an opposite second end, and a neck portion disposed between the body portion and the first end, wherein the neck portion has a circular cross-section defining a first radius and wherein the neck portion defines a longitudinal axis;
a head, comprising:
a flat circular proximal surface defining a second radius that exceeds the first radius, wherein the proximal surface is coupled with the neck portion and wherein the longitudinal axis is perpendicular to the proximal surface and extends through a central portion of the proximal surface;
a spheroid distal surface opposite the proximal surface; and
a lateral surface extending between the proximal surface and the distal surface.
