Pins are all short but the plan says long?

This is ok. Use the short pins and do not drill to full depth. Use a surgical mallet and tap the remaining 3-4 mm’s. If the plan calls for short pins and you only have long, a judgement call must be made. It may be okay to tap through the lingual cortical plate. This solution changes doctor by doctor and where the exit point is, mandibular or maxilla. Long Drills are 25mm and Short Drills are 21mm. Can leave the long drills protruding from the Fixation Base. This is the best option, as the trajectories of the pins should hold the base in place.
