Drill hole for the centring pin using the 2,2 mm pilot drill in the median plane
Drill holes for the implants along the fitted paralleling guide

The paralleling guide is used for aligning 2 or 4 interforaminal implants in the edentolous mandible to the median plane. A hole is drilled in the middle of the mandible using a pilot drill, which is easily aligned to the median plane. The distance to the middle can be accurately transferred to the opposite side by swivelling the fitted paralleling guide.
