The dental implant platform combines the benefits of a taper lock implant abutment interface (IAI) and platform switching with the known restorative advantages of the internal hex. The advantage of the internal hex is that a custom made laboratory locating jig is not required to seat the final restoration. Another cost and time saving innovation.
The taper lock is one of those marvels of modern engineering and is the reason why keyless chucks on power drills work. However in this case it is used in combination with cold welding. A cold weld occurs when two similar materials are forced together such that atoms are exchanged between the surfaces. This join when made accurately enough can be a hermetic one, eliminating microbial leakage.
For two piece implant systems there exists two potential pathways for bacterial penetration resulting in crestal bone loss. One route is through the inside of the abutment, along the screw threads eventually exiting at the implant abutment interface or microgap. Alternatively bacteria can migrate along the outer surface of the abutment. If a cold weld is formed at the Implant-Abutment-Interface (IAI) creating a hermetic seal then the bacteria traveling through the inside of the abutment cannot reach the bone, eliminating a potential cause of bone resorption.
