Brief Summary

Together with materials and type of retention, the stability of the implant abutment connection represents one of the key factor for the success rate of an implant supported restoration. The recent diffusion of high quality and easy to use CAD/CAM systems has contributed to market launch of a number of competing companies that offer the so called "clonical" or "compatible" restorative components. Although they are claimed to be identical, the original abutments are supposed to present maximum accuracy and consequently lower microleakage. The aim of the present randomized controlled trial will be to analyze the implant abutment junction stability comparing implant-supported crowns restored with original components and compatible non-original abutments. The hypothesis is that original components will present significantly better stability than non-original abutments.
