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.

Conditions

• Bone Loss, Alveolar
• Dental Implant Failure Nos

Interventions

Type	Name	Description
DEVICE	Original CAD/CAM prosthetic abutment	Original (Sweden\&Martina) CAD/CAM abutments will be screwed to the implants at 32N/cm.
DEVICE	Compatible CAD/CAM abutment	Compatible (New Ancorvis) CAD/CAM abutments will be screwed to the implants at 32N/cm.
PROCEDURE	Local anesthesia	Infiltration of 4% articaine with 1:100,000 adrenalin (Inibsa).
DRUG	Painkillers	Patients will be prescribed ibuprofen 600 mg three times per day for five days
DRUG	Mouthwashes	Patients will be prescribed mouth-rinse with chlorhexidine 0.12% twice daily starting 3 days prior to surgery and for 2 weeks afterward
DEVICE	Implant placement	Dental implants (Sweden \& Martina, Padua, Italy) will be placed at crestal level and according to the manufacturer's instructions.
