A variety of surgical techniques and materials have been developed to increase the vertical bone height in the posterior maxilla. Minimally invasive crestal approaches for the elevation of the floor of the sinus using a crestal approach have been recently reported to minimize adverse events associated with the use of the osteotome technique for indirect sinus lift. The aim of this study is to r...

Aim: To describe through a clinical case report the surgical sequence of rehabilitation with 3D-printed implantsassociated maxillary sinus floor lift synthetic regenerative materials, including biphasic bioceramic.Case Report: Patient had an agenesis upper left premolars (#12 and #13), vertical bone deficiencycaused by sinus’ pneumatization, horizontal alveolar resorption around missing teeth a...

Openand closed-loop control of vortex shedding in two-dimensional flow over a flat plate at high angle of attack is numerically investigated at a Reynolds number of 300. Unsteady actuation is modeled as a body force near the leading or trailing edge and is directed either upstream or downstream. For moderate angles of attack, sinusoidal forcing at the natural shedding frequency results in phase...

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...

air in the intracranial vascular compartment is rare and only few case reports are published in the literature. without surgery or open head trauma, the origin of air bubbles in the venous sinus is still debated. we report an admitted patient in the emergency room one hour after a severe closed head injury, and in whom, the post-surgical cranial ct scan demonstrated feature of air embolism alon...

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...
