Cutting down on complications

Dental implants already have a very favourable success rate, but certain patients are still at risk of failure in the long-term. By better understanding the reasons for this and the ways in which complications can be reduced, we can help ensure that patients benefit from their implants for many years to come.

Smoking & Diabetes

Smoking can delay soft tissue healing, increase the likelihood of inflammation of the tissues around the implant, and decrease resistance to post-operative infection. Provided diabetes is controlled, it should not adversely affect the patient’s prognosis. Where diabetes is poorly controlled, it can significantly slow osseointegration. Within the first six years of receiving an implant, the success rate for diabetic patients is the same as for those without the condition, though in the long term there is an increased incidence of peri-implant inflammation.

Maintenance

One of the main threats to implant health isperi-implantitis,whichisinflammationof the gums due to bacterial build up. This can result in progressive damage to the hard and soft tissues.

Preventing this largely depends on patients being able to adequately manage their oral hygiene, meaning regular check ups and visits to the hygienist are, of course, highly recommended. Research indicates that around a third of British men only brush their teeth once a day, which enables bacteria to multiply unmolested, giving rise to harmful plaque and tartar. With so many people following suboptimal oral hygiene practises, it is crucial that patients understand how much of a difference improving this can make to their long-term prognosis.

Osseointegration is the process by which the patient’s bone tissue bonds with the implant, providing it with a sound mooring.

Without successful osseointegration, the implant is considered to have failed. Primary implant stability refers to the mechanically induced stability from the procedure (dependent on the properties of the bone, implant and technique utilised). Secondary stability is a measure of how successful osseointegration has been, which is contingent on the primary stability achieved.

Traditional methods of gauging implant stability by using blunt instruments and the percussion test are unreliable and potentially misleading. While microscopic and histologic analysis were historically considered the most accurate means of evaluating osseointegration, they were highly invasive and destructive. New non- invasive diagnostic tools have become popular and can provide very useful diagnostic information.
