In the last 30 years, implantology has made enormous progress to become a highly specialised technology.
Thanks to the new surgical techniques, today increasingly more patients can benefit from implants. Implantology statistics have considerably improved, with the failure rate standing at only 1% of all patients with implants.
The preliminary study
This high success rate is due to greater study of the area to which the implant is to be fitted and its preparation.
At the moment of extraction, it is important to ensure that the piece is cleanly removed and leaves as much bone as possible; this means correcting bone or gum defects.
Images obtained by scanning the upper maxilla or jawbone enable us to obtain a precise view of the height, width and density of the bone into which we want to make the implant. Based on this, we will decide the length, width and shape of the implant to be fitted.
Good periodontal manipulation (i.e. the gum round the bone) when managing implants is a factor which improves implant success even more.
Similarly, the material used to fit implants, their choice according to the case at hand, condition of the bone surface and gums on which the work is carried out and surgical techniques have evolved enormously.
Several factors must be considered:
- High quality titanium implants must be used. They must be made by a recognised manufacturer and have passed a series of exhaustive controls.
- The surface must be microscopically treated for improved fixation to the bone.
- The instruments used must perfectly adaptto the new implant shape.
- Priority must be placed on primary stabilisationof the implant (i.e. the implant must be fixed in place during the operation), causing neither stress nor traumatism.
Pre-implant surgery, increasingly more sophisticated, can reconstitute the bone volume before fitting the implant as follows:
- Ridge expansion or onlay, making it possible to increase thickness of the reduced bone ridge, and to correct its volume and outline.
- Sinus lift surgerywhich, increasing the bone height, enables an implant to be fitted despite the proximity to the maxillary sinus.
In implantology, the failure rate is lower than 1% provided that the process is carried out by an expert dentist.
