COMPLICATIONS OF IMPLANT SUPPORTED OVERDENTURES

The Glossary of Prosthodontic Terms defines overdenture as; “Any removable dental prosthesis that covers and rests on one or more remaining natural teeth, the roots of teeth, and/or dental implants.” Many studies found that overdentures have benefits includes preservation of residual alveolar bone, improvement in masticatory efficiency, increase in retention and stability of denture, and increased satisfaction to patients. The most common complications of implant supported overdentures are loss of implant, peri-implantitis and soft tissue complications, the need for relining, replacement or activation of retentive elements, loss of retention, pop-out of denture teeth, denture base material fracture. The aim of this study is to evaluate the types of complications seen in patients with implant-supported overdentures and identify their relationship with the demographic/prosthetic data’s. Total of thirty-four participants were included in this study who had an overdenture on the implant as a treatment at the Istanbul University and had been using prostheses for at least three months. A questionnaire including demographic information, prosthetic information, and complication information was administered to all participants. Statistical analyzes were performed using SPSS software. P <0.05 was considered significant. Twenty-four participants from total number had complications, 9 of these participants had only 1 complication and fifteen participants had more than 1 complications. Complications were seen on thirteen women and eleven men. The incidence of complications was found higher in men. the mean age of the participants was sixty-five years. The complication rate was found higher in patients who is sixty-five years and older. In this study the most complications were seen in participants have ball attachment. There is a statistically significant relationship between complications and types of attachment. The most common complications were painful and/or inflamed areas on the soft tissue. Within the limits of our research, there is a statistically significant result between age, area of rehabilitation, the material used, type of attachment, and complications. Further studies are needed to confirm these initial findings.
