Implant placement

(I–J) Final drill used is the 3-mm twist drill to finish preparation of the osteotomy site. (K–L) Countersink drill is used to widen the entrance of the recipient site and allow for the subcrestal placement of the implant collar and cover screw. An optional tap (not shown) can be used after this step to create screw threads in areas of dense bone. (M–N) Implant is inserted into the prepared osteotomy site with a handpiece or handheld driver. Note: In systems that use an implant mount, it would be removed prior to placement of the cover screw. (O–P) Cover screw is placed and soft tissues readapted and sutured.
