IMPLANT-ABUTMENT CONNECTION
Implant-abutment connection in the NDI implantation system is built on a hexagonal-conical type. Such
a combined type of fixation has advantages:

• stability, strength and durability after installation;
• tightness of connection;
• resistance to rotation and micromotions of the implant in the bone;
• optimal load distribution on the implant.

The stability and strength of the implant-abutment connection is also ensured by two types of platforms:

• small - for implants with a diameter of 3.6 and 4 mm;
• large - for implants with a diameter of 4.6; 5 and 6 mm.

The difference in the size of the platforms makes it possible to choose the best option in different clinical cases. Implants with a diameter of 4.6 mm, 5 and 6 mm are installed in the region of molars, with increased chewing load.
Implants of smaller diameter are designed for installation in the frontal jaw.

The diameter of the screw depends on the diameter of the implant and the size of the platform in the implant-abutment connection, which affects the strength of the structure.

The tolerance in the implant-abutment interface is ± 0,005 mm
MATERIALS
For the production of the intra-osseous part of the implants, we apply only to the bio-inert titanium alloy of 4th Grade.

We do not use the Grade-5 Ti-6Al-4V alloy including impurities that do not have bioinert properties (4% aluminium and 6% vanadium), because this can lead to different complications in the post-implantation period.

Surgical and prosthetic tools for implant installation are made of special surgical steel.

The manufacturing technology includes sterilization of the implant surface with disinfecting gamma rays. Term of sterilization is 5 years.
SURFACE
The titanium surface of the implant is treated using SMART technology - sandblasting and subsequent etching with
a mixture of acids at a specified temperature.

This effect creates the necessary roughness on the titanium surface of the implant, which increases the contact area with surrounding bone tissue, accelerates and improves osseointegration. In addition, such a surface is free from any residual traces of contamination.

The bonding strength of the SMART surface with bone is confirmed in histological and clinical studies.
