KAT Implants, LLC is the dental implant manufacturer and distributor based in Portsmouth, NH. The single platform of all implants is, by far, the most prominent feature of KAT System. But, although it is the most prominent and arguably the most important feature, it is not the only one. From inventing the new locking taper activation method and Pick-up Abutments™ to utilizing a solid body implant design, KAT Implants is changing conventional implant dentistry.

KAT System includes implants ranging in diameter from 2.5 to 6.5 mm and in length from 6 to 14 mm. All abutments of KAT System can fit any implant and, since the connection between implant and abutment is accomplished via a locking taper, neither cement nor retaining screws are needed.

"Best implant course that I have taken. The one-on-one instruction was excellent. All my questions - even the dumb ones were answered. Uncomplicated system that will fit my general practice."

Herbert L. Gumpright, DDS


"The KAT Implants course was extremely beneficial. The live surgery presentation was fantastic. I recommend the course to anyone interested in implant placement."

Dayton Cambra, DDS


I love the huge variety of implant diameters available from mini-implants all the way to large diameter implants all sharing the same easy-to-use prosthetic connection. My dental assistant commented recently how much she loves the KAT system for that reason. The bone and tissue response around the KAT implants, as well as the overall esthetics have been exceptional. One of my favorite things about the system is the surgical kit.  It is the most intelligently designed implant surgical kit that I have used to date, and I have used several.
