Drilling Sequence


  • Our main drills are available in 6 diameters
  • The first 4mm of each drill is the lesser diameter that steps up to the greater diameter.
  • The drill marked “HB” is used when there is dense or hard bone.
  • In the case of soft bone, we suggest to not employ the final drill.
  • To ensure accurate depth and parallelism we suggest the use of OsseoDent® OSD-PDG-2320

Drilling Instructions

Step 1: With proper irrigation, perforate the alveolar crest.

Step 2: Employ a 1.8mm pilot drill, and with proper irrigation, drill a pilot hole to the appropriate depth marking on the drill. Check the orientation of the initial osteotomy using a Parallel Pin or Direction Indicator (OSD-PDG-2320). If placing more than one implant and parallelism is desired, begin drilling the next site and align as the trajectory of the bone permits.

Step 3: Surgical Drills – Depending on implant diameter and the density of bone at the osteotomy site, it may be necessary to utilize one or
more of the Surgical Drills to widen the osteotomy. To avoid over-preparation, widening drill diameters should be used only as necessary, and
in proper succession. Select the desired Surgical Drill, accounting for the density of bone at the osteotomy site and the diameter of the implant to be placed

Using Your Existing Drills

Many of our surgeons use their existing surgical drills and our final drill. If you wish to do this, the drill to use prior to our final drill should be 4/10 of a millimeter smaller than our final drill.
