Osstem Dental Implant

Outstanding Biocompatibility

Excellent osseointegration between bone and implants. The superior biocompatibility to the bone is attributed to the RBM (Resorbable Blasting Media) surface treatment that uses HA (Hydroxyapatite), which is a major inorganic component (calcium phosphate) of bone and teeth

Optimal Surface Roughness

Osseointegration can be enhanced by the optimal surface conditions. Increasing the contact area with the bone facilitates osseointegration. As such, the surface roughness of OSSTEM Implants ranges 1.2 ~ 1.8, which has been reported as an optimal level of osseointegration. Uniform roughness is also maintained all over the screw threads.

Verification of stability

Proven safety based on various biological tests.
All products of OSSTEM are studied and developed following the verification of biological safety.

1) Cytotoxicity tests (ISO10993-5) : The cytotoxicity tests that were carried out with the extraction eluates from fixtures showed none cytotoxic response.
2) Sensitization tests (ISO10993-10) : The tests designed to assess contact sensitivity revealed no symptoms of erythema or edema; thus proving that the products cause 
neither allergy nor sensitization reaction.
3) Intradermal tests (ISO10993-10) : Neither erythema nor edema was observed during the test designed to assess the local reaction of the tissue, thereby proving that the product is safe for the human body.

Products superior surface cleanliness

Surface cleanliness is the most important factor in successful implant surgeries. Through the Automatic Cleaning System developed by OSSTEM unique technology, OSSTEM produces clean products completely free from residual substances including organic contaminants.
