Patients with prosthetic heart valves are maintained on lifelong oral anticoagulant therapy. The optimal anticoagulant management of such patients during surgical dental procedures has been debated for a long time. Valvular heart disease does not directly affect dental implant outcome; however, there is a major need for preventing potential infective endocarditis. As the cardiac tissue can be damaged in these patients, especially valves, the risk of bacteria-induced infective endocarditis can be high. Preoperative rinses with chlorhexidine can be beneficial together with antibiotic prophylaxis. If any infection persists around dental implants in these patients, necessary steps need to be taken very quickly, such as removing the implants (the infection) under stringent conditions. Patients with valvular prosthesis placement must be vigilant with their oral hygiene to prevent infection. Adult patients on oral anticoagulant therapy, like their healthy counter parts, may have a missing tooth or teeth as a normal because of periodontal problem and for decay. Warfarin, a competitive inhibitor of vitamin K. is a commonly prescribed oral anticoagulant shown to reduce the risk of thromboembolism in patients with mechanical heart valves, deep vein thrombosis, and other hypercoagulable states. Its principle adverse effect is bleeding. The international normalized ratio (INR) is used to monitor therapy so as to make it safe and effective. The target INR varies (2.0-4.5) depending on the reason for anticoagulation. Osseointegrated implants have been shown to exhibit reliable results in the rehabilitation of fully and partially edentulous patients. Many dental implant systems have shown multiyear success rates.90% for fully edentulous patients. Similarly, multiyear studies of dental implants in partially edentulous patients have generally reported success rates around 90Sfor maxillary and mandibular prostheses. [ABSTRACT FROM AUTHOR]
