Genesis - Building
a Biomimetic Surface

 

The BioSpark™ process results in a
hydrophilic implant surface that mimics the chemical
composition and structure of natural bone.

 

 

Creating macro-micro surface roughness.

• The body of the implant is roughened and double-etched creating the macro-micro surface

Anodization – the anatite™ process

• Genesis implants are anodized through an electrochemical process to generate the natural titanium oxide surface, turning the implant to a uniform pink color 

 

The Biospark™ process

• The Anodic Spark Deposition (ASD*) process creates controlled ‘sparking’ to produce a uniform nano roughened surface, enriched with charged calcium and phosphorous ions 

 
 

The result— genesis the biomimetic implant system™

A surface composition that offers:

• A macro-micro-nano texture similar to that of natural bone

• A moderately roughened pink collar to maximize bone levels** and enhance aesthetic outcomes

The BioSpark™ surface contains a unique
combination of properties that mimic the chemical
composition and structure of natural bone 

The hydrophilic surface of Genesis attracts blood to the site. This helps stimulate angiogenesis— a critical factor for endosseous healing—which provides vital nutrients and growth factors to the healing implant site.



During healing, fibronectin attracts and promotes binding of osteoblasts. The preferential absorption of fibronectin on the BioSpark™ surface may account for the enhanced adhesion, proliferation and metabolic activity of osteoblasts.1



Compared to traditional macro-rough surfaces, the Genesis macro-micro-nano increases osteoblast adhesion.

Charged calcium and phosphorous ions in the Genesis nanotexture* fuel osteoblast activity. P ions stimulate osteoblasts triggering bone formation while Ca ions promote bone mineralization.



The nanostructure surrounding the charged ions forms a micromechanical bond between the newly formed bone and the implant.
