Clinical Trial Summary

Implant placement is the solution of choice for replacing missing teeth in a fixed way. However, dental practitioners and surgeons are reluctant to place implants in the population of patients with special needs. They argue different arguments which involve various risk factors. A systematic review shows that it is clear that there is a gap in knowledge about implant placement in patients with special needs in order to argue the choices of prosthetic rehabilitation or abstention based on a scientific evidence-based approach. There is a need of studies with a large number of patients and implants.

The Unit of Special Care Dentistry at the University Hospital of Clermont-Ferrand started to place implants in 2007. This study should present the evaluation of the survival, success and failure rate of implants placed under general anesthesia and of the prosthesis rehabilitation that followed.

Description:

Patients with special needs face multi-level barriers to dental care. Their oral health is worse than those of the general population. Delayed care in one of many reasons that lead to advanced dental disease and a need of more dental treatments. So, patients with special needs are at higher risk of early edentulism, especially since they also are at higher risk of extraction perfomed rather than conservative care. As a result, in addition to social and psychological impacts, this influences largely the oral functioning. Functional problems (mastication, swallowing) appear or are aggravated. A high prevalence of tooth loss exacerbates chewing and swallowing problems. This increases the risk of aspiration and choking, which is a major risk to general health, with bronchopulmonary disease being the leading cause of death in special needs patients. The maintenance of oral functions is therefore essential. However the conventional therapies are not adapted to patients with special needs. In particular, removable prostheses are very poorly tolerated by these patients because of the discomfort and the limitation of autonomy. The maintenance is complicated (higher prevalence of loss and repair). Many authors put forward the difficulty or even the impossibility of making removable prostheses for patients with disorders, Down's syndrome patients, patients with mental retardation or physical limitations and epileptic patients who present a risk of aspiration or ingestion of the prosthesis during seizures. In addition, the presence of associated xerostomia contraindicates the removable prosthesis and indicates the fixed solution. Implant placement is the solution of choice for replacing missing teeth in a fixed way. However, dental practitioners and surgeons are reluctant to place implants in the population of patients with special needs. They argue different arguments which involve various risk factors. A systematic review was performed to summarize the literature available about implant survival rates in patients with special needs. Twelve articles could have been included in a meta-analysis. A mean survival rate of 92% at 47,2 months on average, for an average of 23 patients and 81 implants per study was obtained. It is clear that there is a gap in knowledge about implant placement in patients with special needs in order to argue the choices of prosthetic rehabilitation or abstention based on a scientific evidence-based approach. There is a need of more studies with a large number of patients and implants.
