Abstract:

Recent studies indicate high rates of therapeutic success for osseous-integrated implants in equal measure to partially edentulous patients and the dentate patients.
Nevertheless, even under the most stringent conditions of sterility, surgical procedures and best selection and preparing of the patients, some implants present a failure of osseous-integration. Most incipient failures present evidence for infectious symptomatology shortly after the implant placement, or the insidious development, asymptomatic, of a retrograde peri-implantitis .This study intends to consider the various factors which increase the susceptibility of the patient for the processes of infectious nature, processes that may endanger the success endoosseous implantation therapy. In this context we wish to make the distinction between the immediate failure (a result of a deficient healing process) and peri-implantitis. Although immediate failure may be due to various factors such as surgical trauma, overheating bone tissue during the preparation of the implantary bed, frequently its bacterial nature is identified. The infectious origin of the immediate failure may be due to pre-operator contamination of the receptor site, or due to the hematogenous post-operator infection. The term peri-implantitis addresses to an inflammatory process that interests tissues adjacent to an already osseous-integrated implant causing resorption of the osseous support tissue. The purpose of this article is to evaluate the increased potential of risk for the implantary supra-structure loss under the context complications of biological and infectious origin in patients with history of periodontal disease.
