in many signal processing applications, an appropriate measure to comparetwo signals plays a fundamental role in both implementing the algorithm andevaluating its performance. several techniques have been introduced in literature assimilarity measures. however, the existing measures are often either impractical forsome applications or they have unsatisfactory results in some other applications....

augmentation of the maxillary sinus is a highly predictable and effective procedure to increase bone volume in the posterior maxilla. Success rates are equal to or better than that of all implants placed in nongrafted maxillary bone in or out of the sinus. Consequently, even in situations where the interocclusal dimension is normal or only moderately increased due to loss of bone height, bone a...

A review of maxillary sinus floor elevation as an integral part of restoring the posterior maxilla is discussed. The related anatomy of the area and the current techniques available are reviewed. The classic lateral antrostomy pioneered by Tatum appears to be the most common sinus lift procedure. The more conservative crestal approach, advocated by Summers, provides another effective way of all...

Forty-eight Endopore dental implants were placed in the posterior mandibles of 24 partially edentulous patients. Seventeen of these implants replaced premolar teeth, while 31 replaced molars. Only 7-mm and 9-mm implants were used, and the majority of prosthetic restorations (83%) were single crowns. After a mean functional time of 32.6 months (range, 8.2 to 50.3 months), the implant survival ra...

Maxillary sinus augmentation has been shown to be a predictable treatment option for placing dental implants in areas of posterior maxilla with lack of sufficient residual alveolar bone height.1 The transalveolar (crestal) and the lateral window are the main techniques for the maxillary sinus augmentation with the goal of creating a space beneath the Schneiderian membrane in which to place vari...

Many studies described several parameters which are supposed to determine success or failure in longterm evaluations of dental implants. However, the relationship between crestal bone loss around implants and the location of implant-abutment connection in the bone still needs further investigations.The subgingival microgap between the implant and the abutment, which creates higher bone level re...
