Cement Vs. Screw Retention

Authors

Dr. Collins asks:

In all the courses on dental implants that I have taken this year, the instructors recommend using custom abutments and cementing the crowns and bridges. Some recommend temporary cement and others use permanent cement.

One lecturer provided some vivid demonstrations of what can happen if you torque down a bridge with screws when it does not fit exactly. I am just about to start my first dental implant case – a maxillary second premolar. Should I use cement or screw retention? Is the prevailing opinion in the restoration of dental implants moving in the direction of cement retention? If so, why? I’d be interested in others philosophy and protocols on this subject. Thanks.
