Claim 0:
1. A method of performing a sinus lift procedure on a patient, the method comprising:
accessing the maxillary bone of the patient at a location for placement of a dental implant;
defining a bore at the location beneath the patient's maxillary sinus;
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 first neck portion disposed between the body portion and the first end, wherein the shank body portion defines a first longitudinal axis and the first neck portion defines a second longitudinal axis;
the shank further defining a first head coupled with the first end;
the first head comprising:
a flat first proximal surface that extends radially outward of the first neck portion, wherein the first proximal surface is circular in shape;
a domed first distal surface opposite the first proximal surface; and
a curved peripheral surface extending between the first proximal surface and the first distal surface;

wherein the second longitudinal axis is perpendicular to the first proximal surface and extends through a central point of the first proximal surface; and

placing the dental implant at the location.
