Comparison with Screw-Retained Systems

Advantages over the traditional screw-retained implant systems
System Capability or feature Typical Screw-Retained Implant System KAT Implant System
Number of platforms Multiple (can be as many as three). Number of the abutments that need to be stocked corresponds to the number of platforms One
Small diameter implants able to use standard abutments No Yes, 2.5mm and 3.0mm diameter implants.
Strength of the implant, 5 million cycle FDA implant fatigue test 180-250 N for 3.5mm implants (NobelActive™1 3.5 - 222 N); 300-400 N for larger diameter implants (NobelActive™ 4.3 - 355 N) 425 N for a 3.5mm diameter implant. 3.5mm implants can be used in molar region because of high strength and large surface area
Rotational play of the components (including the implant level transfer copings) Yes, due to manufacturing tolerances No rotational play
Platform shifting / switching / changing Yes, in some systems, but only horizontal Yes, horizontal and vertical
Diameter of the transgingival portion Larger diameter transgingival portion decreases the volume of the gingival tissues and does not contribute to the esthetics and health Consistent 3.1mm for all implant sizes. Increased volume of the gingival tissues promotes high esthetics and health
Microgap Varies with the system Eliminated due to a 1.5º locking taper design
Pick-up coping for an implant level impression Needed Not needed, abutment acts as a pick-up coping
Can the vertical "sliding" of the components be predictably reproduced during implant indexing and abutment installation? Impossible to achieve due to machining tolerances if a conical or a locking taper connection is utilized Yes, to within 10 microns for cement retained restorations; even more accurate with screw retained restorations;
