Small tap to crack the Sinus Floor elevating the SinusFloor and Schneiderian Membrane in “Trap Door Fashion.” All autogenous bone collected using the unique multiplecutting surfaces of the pilot osteotomes will be puashed into the space created between the floor ane the membrane.
	The site is now prepared for inserting a 3.3mm ACE Screw-Type Dental Implant. For larger sized implant sizes and styles additional step and final osteotomes are used. As required, autogenous bone or bone graft mix can be added to the osteotomy. The ACE AutografterTM can be used to obtain
	Placement of the appropriate length and diameter Implant will utilize the new formed bone depth and push the sinus membrane into the sinus cavity. For Larger diameter implants (3.75, 4.0, 4.75,mm Self-Tapping or 3.5, 4.0, 5.0mm Press Fit): Increase the diameter of the osteotomy using the appropriate step and final osteotomes.
