The SA Surface Treatment is a proprietary refinement applied to Osstem dental implants, combining alumina sand‑blasting and acid etching to generate a unique microtopography. This process creates a network of craters and micro‑pits with a controlled roughness (Ra ≈ 2.5–3.0 µm) that significantly increases the implant’s surface area for bone contact.
This enhanced morphology promotes faster osteoblastic cell activity, improving early osseointegration, mechanical stability, and ultimately reducing healing time and supporting predictable restoration.
Why It Matters for Clinicians
Selecting the optimal implant surface is key for restoration predictability and clinical efficiency. The SA Surface supports faster, stronger bone integration—crucial for high-demand cases such as early or immediate loading, compromised bone quality, or aesthetic zones. Clinicians benefit from reduced treatment time, fewer complications, and more reliable results—even in challenging clinical scenarios.
The Sand-blasted & Acid-etched (SA) surface increases surface area by 45% compared to RBM surfaces. Bone healing is accelerated by 20%, leading to reduced healing times.
For patients, the SA Surface means confidence in their treatment results. With our SA surface Implants, you and your patients are given several benefits due that enhances biological healing and primary stability.
The clinical reliability of sandblasted and acid-etched (SA) surfaces has been confirmed by long-term studies. In a 12-year follow-up, implants with this surface demonstrated a cumulative survival rate of 96.1% and predictable outcomes when applied under strict clinical protocols, even across different types of prosthetic restorations.
