Intoduction in Basal cortical integrated implantology
The mainstream in dental implantology today uses conventional screw-type (and two-stage) implants. But the limitations provided by the native bone either prevent treatments at all or make them complicated and lengthy. Through this technology many patients could not be treated with implants at all, even though they needed and wanted them.
At the turn of the century, the time had come for us to search for true progress in dental implantology. That this would require a new way of thinking has become obvious, since the development of traditional implant systems seem to have been locked in attempts to modify implant surfaces. The inherent limitations of cylindrical and screw implants were, and are, unfortunately too often taken for granted and never seem to be questioned. On the contrary – more and more complicated and at the same time risky surgical procedures are being included into routine protocols, and bone graft donor regions are identified, all in an attempt to adapt the shape of the bone to the shape of the conventional implant rather than the other way around. In doing so, great effort is expended to force the build-up of bone in regions of the body where there had never been any bone in the first place or where the body had (often for good reasons) eliminated any bone that may once have been present. These bone augmentation procedures are associated with additional pain, considerable risks, and enormous cost. The require treatments often over many years and in some case stable results are nevertheless not achieved. That such attempts are made at all, is usually justified by pointing out the alleged absence of alternatives.
But alternatives, true alternatives, exist – and they work.
The BOI® principle has allowed to provide fixed restorations for every patient, without exception, who has ever approached for them. The distal areas of the mandible no longer present with borderline situations from the point of view of the implantologists, nor does the maxillary posterior region. The situation has improved tremendously. We are today able to provide implants to patients where bone augmentation procedures and implants placed by oral and maxillofacial surgeons have failed.
