Biomet 3i Abutment Screw

There are few experiences more aggravating than an implant abutment coming loose due to a faulty screw. Generally speaking, most implant companies make a "lab" screw and a "final" screw. However, in practice, most doctors utilize the lab screw provided by the lab for the final insert. For standard titanium screws, this is generally acceptable as the screws will rarely ever strip. However, if the lab mistakenly uses the final insertion screw, the screw can strip and problems may ensue. This is specifically an issue with Biomet 3i as they provide a "gold" final screw. As gold is a soft metal, any significant torque by the lab can strip the screw threads. It is highly recommended that the doctor use the gold screw once and only once upon insertion.
