3. Morphology of BOI Implants and Related Designs

That Straumann went from TPS coating to SLA coating is remarkable in more than one respect. As late as in 1997, Buser had shown in a broadly designed study that TPS-coated full screws of the ITI type are extremely resistant. Nonetheless, Straumann abandoned this design and started marketing the SLA coating, without any equal study showing that the SLA coating is superior. It is hard to understand why a product is abandoned that had had “scientifically proven” success without first demonstrating the superior qualities of the successor product. To this day, many users cite the above-named study, a study that had been performed using completely different implants that are not even available on the market today and where only a single design feature still corresponds to the scientifically tested implant: the intraoral coupling design (internal cone and internal octagon). Good marketing allows the selling of a brand new product with proven long-term success!
