infections, it can also cause highly invasive and potentially lethal infections, including necrotizing pneumonia, septic cavernous sinus thrombosis, and pyogenic brain abscess. The fulminant nature of these unusual cases has led many investigators to speculate that CA-MRSA may be more virulent than HA-MRSA. In fact, CA-MRSA strains have been shown to be more virulent than HA-MRSA in neutrophil ...

BACKGROUND The primary objective of this study is to use histomorphometric techniques to evaluate the concept that the new bone formed in the maxillary sinus lift procedure emanates from the endosteum of the sinus floor. In addition, the effect of the residual crest vertical dimension on the graft outcome and assessment of osteoclast numbers as an indirect measure of a connection between the cr...

OBJECTIVES An aberrant sinus anatomy or pathology can influence the sinus lift technique if it is encountered during surgical exposure. The purpose of the present study was to determine the prevalence of sinus disease and variations of normal anatomy among edentulous patients prior to sinus augmentation. MATERIAL AND METHODS 120 patients attending a private surgical practice (53 women and 67 ...

Introduction After the loss of teeth in the posterior maxilla, the thickness or vertical height between the alveolar crest and maxillary sinus may be insufficient to place dental implants. At present, maxillary sinus lifting has become a widely used technique for augmenting bone tissue volume in the maxilla. Various surgical techniques can be applied to achieve a sufficient bone volume in order...

For more than 30 years the maxillary sinus augmentation graft has been a mainstay of implant-directed maxillary reconstruction. The purpose of this article is to review the fundamentals of maxillary sinus reconstruction including anatomy and physiology of the sinus, indications for surgery, preoperative evaluation, surgical techniques, and management of complications. While there are some relat...
