Claim 14:
15. A method of performing a sinus lift procedure on a patient, the method comprising:
accessing the maxillary bone of the patient at a location;
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 first longitudinal axis;
a head, comprising:
a proximal surface having a circular cross-section defining a second radius that exceeds the first radius, wherein the proximal surface is coupled with the neck portion and wherein the first longitudinal axis is perpendicular to the proximal surface;
a spheroid distal surface opposite the proximal surface, the spheroid distal surface comprising at least one groove defined therein or at least one projection extending outwardly therefrom.
