The uniqueness and exceptional geometrical shape of ARDS' implants, as well as the special drilling technique, ensure a reduction of drilling volume along with an additional gain of primary stabilization.

ARDS dual thread implants have a varying screw width and an internal hex. There is one screw width along the entire implant – the upper part's thread starts at 0.2mm depth and gradually deepens to 0.9mm after 5.5mm from the top.

The upper part, 5.5mm long, is consisted of two threads in order to increase the implant's surface area, and is designed to better grasp at the cortical bone.

The lower part, slightly tapered, is consisted of 0.9mm deep thread and wide tread in order to allow better grip at the spongiosal bone.

The second thread overlaps with the first and ends after 5.5mm from the top; the advancement of these two threads is identical on the upper and lower parts, so that the implant advances at an equal pace through its entire length.

The drilling method and its stages

1. Using the marking drill to set the implant site.
2. Performing a first pilot hole for the entire implant's length with a 2mm drill bit, suited for the 8mm, 10mm, 11.5mm or 13mm implants.
3. Inserting a leading pin into the pilot hole. The diameter of the pin is 2mm and its length is 16mm – longer than the length of the pilot hole. The pins must be fully inserted into the pilot hole and will always protrude above the bone.
4. Additional 2.8mm, 3.6mm, 4mm and 4.2mm trephine drills are shaped uniquely. The hollow drills are placed over the guiding pins in order to drill the cortical bone to a 5.5mm depth.
   
   
   
   
5. In case of a type I bone, the pilot hole's diameter needs to be enlarged using the 2.8mm drill through its entire length.

Inserting the implant into the pilot hole

When the implant is inserted into the pilot hole, its lower part is screwed in the first 5.5mm of the pilot hole. From this point the implant continues by self tapping into the bone as it intersects and compresses it.

The procedure's advantages

1. Saving 40% of the bone by reducing the amount of drilled bone.
2. Significantly shortening the process of bone-implant integration due to a unique design of the implant which increases bone-implant contact in the surgery phase (in comparison with conventional implants of the same diameter).
3. A drilling method combined with the shape of the implant which results in the compression of the spongiosal bone around the apical part of the implant during its insertion. Thus, the forces are dispersed along the entire implant and not only at its upper part, as in common implants held only at the cortical bone at the end of the implant.
4. The drilling method enables precise control over the placement and shape of the bore hole. This is attainable by the usage of leading pins which direct the drill at the correct angle throughout the process and stabilize it, also in thin ridges.

Please note – while we recommend using ARDS unique drilling technique, it is possible to use ARDS implants with standard drills as well. In such cases, the drilling should be 5.5mm deep, after which the insertion of the implant is as described.
