Developed by a Portsmouth, NH dentist Vitali Bondar, DDS, KAT Implants is a manufacturer and distributor of a patented dental implant system designed to have:


Stronger Implants

KAT implants are extremely strong, much stronger than other implants of larger diameters as proven by independent fatigue testing.

Comparison of mini dental implants strength. KAT dental implants are much stronger than conventional implants.
Hollow implants are not as strong as KAT dental implants. X-ray of fractured implant taken by Vitali Bondar, DDS Portamouth NH implant dentist.

Why are stronger implants good for you?

Stronger implants are less likely to fracture. The x-ray  on the left shows another manufacturer's fractured hollow implant. This is impossible to fix and the implant must be removed by drilling away bone.


On the right side is the x-ray of KAT 3.1mm diameter implant that replaced a molar. The implant has been in function for two years. Notice the healthy bone surrounding the implant.

KAT mini imlplant was placed by Vitali Bondar, DDS - Portsmouth, NH implant dentist who is the inventor of KAT dental implant system.

Streamlined Procedure

When your tooth is replaced with an implant you will actually have three individual parts connected to each other:

  1. Implant - a screw that is placed in your jaw bone
  2. Abutment - a "stump" that is attached to the implant
  3. Crown - a tooth colored cap that is cemented on top of the abutment


All implant systems have multiple implant diameters to be used in different situations... Small diameter implants for thin ridges (2.5 and 3.1mm diameters), standard diameter implants (3.5 and 4.3mm diameters) for medium ridges, wide diameter implants (5.0mm diameter) for wider ridges and finally extra-wide diameter implants (6mm and wider) for really wide ridges or for placement into large extraction sockets.


All other systems have separate abutment lines to fit different diameter implants. Same as different allen wrenches fit in different sockets. On the other hand, all KAT abutments fit all KAT implants regardless of diameter. This reduces the inventory that the dentist has to have and increases the likelihood that the ideal abutment size will be attached to the implant.

No Loose Retaining Screws

The abutment of a typical implant system is attached to the implant with a retaining screw. It has been proven that retaining screws lose retention after years of chewing and can come loose. This results in loose abutments and the need to make new crowns.


KAT system utilizes locking taper connection to hold the abutment securely on the implant. In fact, we have not received any reports of loose abutments since introduction of KAT Implants in 2009.


The best way to demonstrate how locking taper connection works is to press two Home Depot buckets together really tightly and then try to take them apart. Not a simple task! Now imagine that the buckets made from titanium and have been pressed by a powerful press. That's how KAT System works and we hold the patent that protects this method (US Patent 8,469,710)! The video below demonstrates how simple it is to place and remove KAT abutments.

There is another locking taper connection system on a market - Bicon implant system. To attach Bicon abutments to implants one must use the hammer to hammer the abutment in - a very unpleasant task for the patient indeed! To remove Bicon abutments one must use extraction forceps and twist abutment off, much like taking the tooth out!


Watch this video to see how it is done with KAT System!

Less Bone Grafting Surgeries

Since the strength of KAT implants is at least double the strength of similarly sized competition implants, it is possible to use smaller diameter implants in thin ridges without prior bone grafting procedures! This approach saves time, money and requires only one surgery!

Less Long-Term Bone Loss Around Implants

KAT implants have been placed in patients since 2009. Every implant placed by Dr. Vitali Bondar, the founder and owner of KAT Implants, is documented and cataloged on our home page in the Transparency Project section. Please see for yourself how stable the bone is around KAT Implants. Historically, bone loss of 2mm within the first year of implant function is deemed a success. Thanks to a locking taper connection KAT implants exhibit negligible bone loss over multiple years!
