A 49-year-old woman with mitral and tricuspid mechanical valve prostheses developed marked weight gain with increasing abdominal girth and facial plethora 4 weeks after anticoagulation was temporarily interrupted for abdominal surgery. Transthoracic and transesophageal echocardiography documented severe tricuspid stenosis and regurgitation. The two discs of the tricuspid prosthesis were immobilized, half open and half closed.

Abstract:Prosthodontic rehabilitation of a patient with compromised edentulous ridges in a conventional manner is a difficult task. Modifications in the treatment procedures should be considered to fulfil the patient's functional and esthetic desires. This article reviews the various compromised situations commonly encountered in a routine clinical practice and the possible management of each of them.
This article reviews the various anatomical facts significant for preoperative planning of implant procedures in the mandible and the maxilla. This planning includes the precise evaluation of distinct anatomical factors, such as the position of the mandibular canal, the maxillary sinus, the width of the cortical plates, the existing bone density , appropriate implant selection and planning the most appropriate implant position in the existing clinical condition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
