Retrospective on Treating Periimplantitis

1st European Workshop on Periodontology in 1994 defined Periimplantitis as the inflammatory reactions in the hard and soft tissues, with loss of supporting bone, surrounding a dental implant exposed to the oral environment. A successful dental implant is defined as immobile when tested clinically. Vertical bone loss is less than 0.2 mm annually following implant first year of service, as well as, the absence of pain, infection, neuropathies, and parasthesia .
There are a number of reasons for an implant to fail. They include
a) Implant overstressed due to hyper-occlusion
b) Apical pathology from adjacent tooth
c) Retained cement on cementation of prosthesis
d) Residual bacteria left from either endodontic, periodontal pathology

The aim of this article is to present most common causes of periimplantitis and to show treatment for each of these. Somecauses can be prevented by careful use sound clinical skills and others byprevention of chronic inflammation, recognizing early signs of soft tissue inflammation around a dental implant. This article will focus on each of these failures and provides a treatment protocol or prevention for these problems.
 Periimplantitis
Case Studies: Overstressed implants:
Over functioning on implants is a problem. Either due to overloading on completion of the implant case, or due to changes in restorations opposing an implant can cause this scenario. The first case that exhibits this is a female that had a single implant placed distally that was designed to take compressive forces on a free-end-saddled partial. The patient was to return back to her referring dentist to reline the distal saddle. The patient did not do as instructed, and after 3 years the patient presented a buccal fistula.
