Periodontally associated complications & Failures of dental Implants

Dental implants according to American Dental Association is defined as a device specially designed to be placed surgically within or on the mandibular or maxillary bone as a means of providingall dental replacement. Any deviation from the normal osseointegration because of dental implant infection rejection overload failure bone loss inflammatiom incision line opening etc are included in complication of dental implants. There are two kinds of complications depending on the time they emerge: early and late. Complications might indicate an increased risk for a failure but are of either temporary significance or amenable to treatment. Failing implants or complications in the soft tissues can be of three types namely peri-implant disease peri-mucositis and peri-implantitis Implant failure may be defined as the first instance at which the performance of the implant measured in some quantitative way falls below a specified acceptable level.Failures can be divided into biological failures and mechanical failures of the components.Only by using a good work protocol we can detect the local and systemic risk factors that could determine the success of the treatment.
