IMPLANT CONNECTIONS
CloseFit™ Conical-Hex
The proprietary CloseFit™ dental implant connection combines a unique internal conical-hex Morse Taper implant-abutment interface, and platform switching. In addition to the known restorative advantages of the internal hex, this platform minimizes micromovements between the implant and abutment, thus eliminating potential bone loss.
How does this work?
Once assembled, the CloseFit™ forms a cold weld between the implant and abutment. A cold weld occurs when two similar materials are forced together. When made accurately enough, this connection can be a hermetic one, eliminating microbial leakage. For two-piece dental implant systems, microbial leakage and colonization between implants and their abutments may cause unwanted inflammatory reactions and crestal bone loss. Bacterial penetration can occur through the inside of the abutment, along the screw threads, and/or along the outer surface of the abutment. If a cold weld is formed at the dental implant-abutment-interface, then the bacteria travelling through the inside of the abutment cannot reach the bone, eliminating a potential cause of bone resorption
Standard Internal Hex
The Standard Internal Hex connection is a widely used implant-abutment interface. This connection incorporates a 6-point single hexagon. The hex functions both in engaging the driver or the mount tip during implant placement, and in providing an anti-rotational fit to the prosthetic component. The geometrical design of the system ensures proper implant-abutment seating, reduces horizontal bone stresses, and uniformly distributes forces within the implant, therefore minimizing excessive loading on the retention screw.
Additionally, the Internal Hex allows for excellent esthetic results.
