We concluded that extraction screws provide better clinical results when they have some bend or “give” before breaking. In short, a successful extraction with a bent screw is better than an unsuccessful extraction with a broken screw.

In a nutshell, under certain clinical circumstances bending a screw is an expected and perhaps even a necessary part of a successful extraction. However, by using proper extraction technique, as described in our detailed written instructions, dentists can m
