Anesthetic risk : Although, under local anesthesia in the vast majority of cases, the anesthetic risk is never zero. An allergy, extremely rare, is always possible. However, this type of anesthesia is widespread and “at risk” subjects are often already known.
Non-osteo-integration (called « rejection ») : It is translated in the weeks or months following the installation of the implant.
The material used is pure titanium, whose physical and biological properties are very well known and used for many years in orthopedic surgery (hip prosthesis, knee …). It is very well tolerated by the body and no rejection or allergy reaction has been reported so far.
The bone cells did not colonize the surface of the implant and it is mobile because not “welded” to the bone. It will then be necessary to deposit the implant. This is why we usually wait 2 to 6 months before making the final prosthesis on the implant.
The causes are not always identified, however, tobacco and hygiene play a significant role.
Overall this affects 5% of implants posed The 100% success does not exist for implant treatments.
However, if it is possible, you can put an implant in the same site a few weeks or months later, and often this second attempt is successful.
Infections : Post-operative infection is rare. It is either a neighboring abscess or (much more rare) a soft tissue infection around the jaw bone (an infection called cellulite) or sinus infection (sinusitis).
This is why antibiotic therapy is prescribed to you, that the aseptic conditions must be drastic and that we must avoid operating when the body is weakened (by another infection, poorly balanced diabetes …)
Hemorrhage : As with any oral surgery, there may be haemorrhage or hematoma, but this is not serious in the vast majority of cases.
Lesions of the nerves :
At the level of the lower jaw (mandible) there is the sensory nerve of the lip and the chin that travels in the bone (in the region of premolars and molars). This is why a scanner is also required to locate it, and sometimes, if the bone height is insufficient, you will be rejected for an implant placement in this area. Very rarely the nerve can be touched, during the pose (technical error, poor appreciation of the scanner, patient moving at the time of drilling …), or after a hematoma or edema compressive. This results in a decrease in the sensitivity of the lip and chin (not paralysis). Generally, by proper treatment, these disorders are reversible.
Exceptionally, there may also be a lesion of the lingual nerve that gives anesthesia of the edge of the tongue.
