13 Jul Implantology: Where do we stand?
Since the work of Prof. Bränemark’s team in Göteborg (Sweden) on osseointegration, implantology has made considerable progress and has become a highly specialized technology.
Thanks to new surgical techniques, more patients can now benefit from implants. Implantology statistics have improved considerably, with the rate of failure falling to 1% in implanted patients.
This high percentage of success is due in part to a better study of the implant site: preparation of the site, whether at the time of extraction or when correcting bone or gingival defects, is essential.
The cone beam imagery (3D scanner with significantly reduced radiation) allows immediate visualization.
Consideration of the periodontal approach (condition of the periodontal tissue that surrounds the implant) in the implant management is an element that further improves the success rate of this surgery.
Thus, the material specific to the implant placement, the choice of the implants, their surface condition and the operating techniques have evolved greatly; Even if certain key principles remain immutable:
- Use only pure titanium
- Use an instrumentation perfectly adapted to the new shape of the implants
- Promote primary stabilization of the implant, without effort or trauma
Preimplant surgery, increasingly sophisticated, can restore bone volume before implantation by:
- Peak or apposition expansion surgery to increase the thickness of a resorbed bone crest and correct its volume and contours.
- Intra-sinus bone surgery which, by increasing the height of the bone, makes it possible to place an implant.
Thanks to an implant, it is possible to replace at once a missing tooth. Indeed, for the comfort of the patient who is not obliged to wait several months before having a definitive tooth (especially in the visible regions of the smile), it is possible to carry out an immediate loading by placing a crown Directly on the implant.
