Screw vs. Cement Retained Implant Restorations - How to Choose?

3/30/2015

Recent studies have shown that screw-retained implant restorations are more biocompatible than cement-retained restorations.  It is therefore recommended that cement-retained restorations be limited to the following situations:

1) When a screw access hole would result in unsupported material (greater resistance to porcelain fracture).
2) When resistance to offset loading is desired (allows forces to be better distributed along the axial inclination of the implant).
3) When a screw access hole would be visible (enhance esthetics).
4) When an intact occlusal surface is desired (occlusal table can be adjusted).
5) To correct implant malposition or angulation.
6) To reduce treatment costs.
7) To simplify the fabrication procedure.
8) When a passive fit is desired (40µm of cement space can compensate for laboratory distortions).
9) When a patient has limited opening.
