Implant Design and Surface Features
SLA Surface Properties
A SLA surface produced by sandblasting and double etching process, produces an homogenous rough surface with a 1.8 micron Ra. This type of surface micro-texturing has been shown to promote and stimulates early bone attachment to the implant surface. Energy-dispersive X-ray spectroscopy (EDXA) confirms that the implant surface is free of biocontamination which can result in poor bone to implant surface contact and even failure to achieve osseointegration.
Faster and enhanced osseointegration is developed through the maintenance of intimate bone contact with the implant surface during the early stages of integration.
At three weeks the pure SLA facilitates bone contact with the implant surface following insertion ensuring primary fixation.
At 6 week the bone healing response to the SLA surface is excellent and histology confirms new bone ingrowth has occurred and is occupying the space between the threads.
This type of rapid bone formation is essential to the success of early loading and the development of secondary fixation.
Electron microscopy shows intimate bone contact and healing response to the SLA implant surface.
Implant Design Features and Philosophy
The implant system has been developed in accordance with the six critical factors that influence the process of osseointegration.
