Are there any special precautions we should take when doing site development, bone grafts, sinus lifts or installing implants in organ transplant patients? Most organ transplant patients will be taking immuno-suppressive drugs and will this decrease their resistance to infection? Should we be prescribing antibiotics for all invasive procedures that involve bleeding and the potential for creating a bacteremia? Should we have these patients on chlorhexidine rinses? Should we have these people come at 3 month intervals for recall examinations and oral prophylaxis? Are there any absolute or relative contra-indications for implants in these patients? Is time since organ transplant a factor? If let us say a patient had a kidney transplant 7 years prior, is this patient still considered at risk for complications that might leading to rejection of the transplant?
