Surgery RisksIf the position of the sinuses and the nerve are very important during the first surgery, one or several radiographs are needed. If the dentist touches a nerve while screwing in the implant, you may feel constant numbness in your gums, chin and lips.
Also, there must be enough bone in the jaw for the dental implants to be properly integrated. If the dentist does not estimate properly the amount of bone or if the bone hasn’t enough strength, the implant will be rejected. If there is not enough bone, a bone grafting procedure or a bone augmentation must be performed prior to the insertion of the implant titanium screw.
The implant may also be poorly positioned, which may lead to failure eventually.
Peri-implantitisDental implants cannot develop caries, but the surrounding area may get infected and cause complications or the loss of the implant.
Peri-implantitis is an inflammation of the area surrounding the dental implant; the tissue or bone near the implant may get infected due to different bacteria, viruses or poor dental hygiene and this will eventually cause the loss of the implant screw and the bone surrounding it.
If detected in timely manner, an infection may be treated and the loss of the implant is not imminent. Make sure to call your dentists whenever you feel something is wrong or have swollen gums in the implant area.
Make sure to keep your teeth clean and use an interdental brush to prevent the deposits of plaque and bacteria in between the teeth and the implant. Diabetics and smokers are also exposed to developing peri-implantitis.
Rejection of the ImplantA low percentage of people may reject the implant. This may be due to intolerance to titanium, but the exact causes have not yet been established.
The implant is also considered rejected if it is mobile or if the bone loss around the implant screw that is exceeds 1.0 mm in the first year and more than 0.2mm in the second.
People who grind their teeth may reject the implant, due to the additional pressure that is added on the implant. Teeth grinding may also lead to bone resorption or even fractures.
Smokers are more likely to reject a dental implant, so dentists recommend quitting prior to the installation of the implant screw.
Receding GumsIn some cases, receding gums may reveal part of the implant screw and this will facilitate the access of bacteria, leading to frequent infections and possibly the loss of the implant.
The success of a dental implant surgery depends on the skills of the dentist as well as the initial health of the bone and the surrounding tissue and the maintenance after the surgery. However, dental implants are successful about 95% of the times.
