Surface Treatment : SLA or RBM?

S.L.A - Stands for Sandblast, Large grit, Acid-etch.

A surface treatment that sets to Improve the implant's properties, yet to keep its rudimentary qualities intact.

SLA Treatment Process:

The implant's surface is blasted with corundum particles of aluminum oxide, acquiring micro-roughness.

The next step - dipping the implant into a high-temperature mixture of sulfuric & hydrochloric acids, the result is: micro-cavities of 2-4 microns will form.

SLA biological point of view:

Just like in the small intestine, where mucosa cells contain microvilli which are tiny hair-like projections, that increase the surface area of the small intestine allowing more area for nutrients to be absorbed – A similar biological mechanism is achieved by SLA implant surface treatment.

By increasing the surface area of the implant, we allow for better osteoblast proliferation and cellular adhesion, thus increasing the bone to implant contact, resulting in an excelled process of osseointegration.


Taking tissue integration to the next level, SLA treatment succeeds in producing a surface topography, that provides an ideal structure for cell attachment.

Many documented pre-clinical & clinical studies done on implants following an SLA treatment indicate a survival rate of 98.8% (95.1% )in a 5 (10)-year follow-up, with low-to-none prevalence for peri-implantitis along with faster healing time.

SLA is the most popular implant surface treatment up to date. Utilized by the largest dental companies on the market.


RBM – Stands for Resorbable Blast Media.

The core idea underlying RBM surface treatment is to generate a rougher surface.

Rougher surface increases the overall surface area of the implant, allowing for a more sufficient

bone to implant cohesion and retention characteristics, thus increasing the osseointegration of the implant.

RMB Treatment Process:

Achieved by “high-speed particle blasting” using

suitable & resorbable hardened Beta-TriCalcium Phosphate particles.

Following the mechanical abrasion, leftover calcium particles cleaned off by etching the surface with organic acid of low concentration, leaving no residue and avoiding the implant’s titanium surface refurbishment.

RBM Mechanical & Biological Properties:

Successful osteogenesis around the implant is obtained due to the created homogenous pore diameter and uniform surface.

bTCP (Beta-TriCalcium Phosphate) is a resorbable, biocompatible substance used in alloplastic bone grafts.

bTCP does not transfix deeply into the implant's surface

and does not lodge inside the physically created crater.

In case there is bTCP leftover residue on the implant surface, it adds to the osteogenic value of the implant due to the osteoconductive properties it possesses, allowing it to be completely resorbed and replaced by new bone cells.

RBM Implant Treatment has the Following Advantages:

• Cleaner Implant surface

• Mineralized bone formation contributed by optimal homogenous pore diameter.

• No Titanium nor acid residues are left.

• Accelerated Healing & Osseointegration.

• Enlarged implant surface area for optimal contact.
