CRESTAL BONE DRILLS & BONE TAPS
Purpose: Removes cortical bone at ridge crest to facilitate pressure-free seating of the implant collar.
• Site Specific. Indicated when dense cortical bone is present at crest

• Used following the final Width Increasing Drill for each implant
• 850-2,500 rpm with steady irrigation11 Do not fully seat the drill if all or a portion of the collar is to be left supracrestal. Fully seating the
drill allows the implant to be placed with the prosthetic platform level with the crestal ridge.
Partially seat drill.
(Supracrestal)
1mm left above osseous crest.
• Preparing to Level 1 allows placement of the prosthetic platform level with the crest.
• Preparing to Level 2 allows placement of the Cover Screw level with the crest, provided the osteotomy
has been prepared to accommodate the additional depth.
Purpose: Prepares dense cortical bone for implant threads.
• Site specific
• 30 rpm or less12 • Final instrument prior to implant placement
• Square drive shaft interfaces with Ratchet and Hand Wrench
Place the tip of the Bone Tap into the osteotomy, apply firm apical pressure
and begin rotating slowly in a clockwise direction (30 rpm or less is
recommended) 12 . When the threads engage, allow the tap to feed without
excessive pressure. To remove, rotate the Bone Tap in a counter-clockwise
direction, allowing it to back out of the osteotomy.
Do not pull on the Bone Tap to remove it from the site.
