1. A method of utilizing an ultrasonic instrument comprising:
obtaining an ultrasonic instrument, comprising:
a tip portion;
a transducer configured to convert electrical energy into vibrational energy;
an acoustic transformer interconnecting the transducer and the tip portion; and
a portion disposed at least partially about the acoustic transformer, the grip portion coupled to the acoustic transformer via a soft mount comprising a resilient nodal coupling at a nodal region of the acoustic transformer, the resilient nodal coupling comprising:
a resilient mount disposed at the nodal region of the acoustic transformer; and
a nest defined within the grip portion, the nest configured to receive and contain the resilient mount,
 wherein the resilient nodal coupling is structured to provide rotational and axial stability to the acoustic transformer by minimizing the lateral and longitudinal movement of grip portion relative to the acoustic transformer during static and dynamic phases of use of the ultrasonic instrument,
 wherein the resilient nodal coupling includes a resilient mount disposed at the nodal region of the acoustic transformer, the resilient mount applying at least one of radial pressure or lateral force to the acoustic transformer,
 wherein the resilient mount includes a pair of opposed protrusions defined at the nodal region of the acoustic transformer and a resilient member disposed about each of the protrusions, and
 wherein an area between the acoustic transformer, the grip portion, and the nest provides a pathway for coolant fluid to flow across the soft mount;
grasping the grip portion; and
orienting the tip portion along a line angle of a tooth.
