Implants’ Surface Treatment

AB Dental’s surface treatment enhances bone formation around implants and improves osseointegration. Our physical and chemical modifications create a highly consistent microroughened surface needed to stimulate bone formation around the implant.

 

Osseointegration is a tightly regulated biological process that occurs immediately after implant placement. The cells are sensitive to implant surface properties including topography, chemistry, and wettability and respond to these properties by either creating bone on and around the inserted implant or by creating a fibrous collagen tissue resulting in pain and implant failure. Not all implants are made equally. Scientific research has shown that Titanium and Ti alloy (Ti-6Al-4V ELI) implants that match the physical topography of bone increase implant integration and reduce healing time compared to smooth or machined implants.

 

AB Dental has developed a new surface treatment to enhance bone formation around Ti-based implants and improve implant osseointegration. This novel surface uses physical and chemical modification methods to create a highly consistent microroughened surface needed to stimulate bone formation around the implant.
AB Dental implants undergo a special treatment starting with RBM (Resorbable Blast Media) blasting with Biological Calcium-Phosphate particles for surface roughening and followed by several thermal acid etching treatments to enhance the implant surface and provide it the perfect roughness and microstructure. The final, highly clean, free of contaminates, biological surface with a high surface area provides direct
attachment of the bone to the implant and promotes fast and optimal Osseointegration.
Next, the implants are sterilized by Gamma irradiation to ensure optimal clinical success for patients.

 

A Morphological scanning electron microscopy of the novel biomimetic surface at the macro, micro, and nanoscale show complex roughness at all different levels including Nano roughness (Figure 1).

Figure 1: Morphological scanning electron microscopy of the novel biomimetic surface at macro, micro, and nanoscale. 20Kx and 50Kx images show osteoclast-like pits on the surface of the Ti6Al4V implant surface. 100Kx image shows nanoscale topography like that of collagen fibrils on a native bone surface.
