OBJECTIVE This paper describes a case of secondary mandibular bone reconstruction performed to place dental implants. Osteosynthesis and simultaneous irregular trifocal distraction osteogenesis were documented. PATIENT The patient was a 51-year-old man with recurrent ameloblastoma of the mandible. Segmental mandibulectomy for tumor ablation and immediate mandibular reconstruction were perform...

Dilemmas accompanying esthetic zone implants frequently involve a dehiscence type defect of the midfacial tissues. The challenge to the surgical-restorative implant team is to understand the etiology associated with such defects and the treatment options that can be offered lending to predictable outcomes. Etiologic factors are: 1) poor implant spatial positioning; 2) incorrect abutment contour...

A modified Code Noise and Multipath (CNMP) algorithm is presented for dual-frequency differential GPS precision approach and landing. Pseudorange noise and multipath are exchanged for reducible biases in both reference station and aircraft ranging measurements. The second frequency is used only to correct the code-minus-carrier observable. Corrected pseudorange measurements are combined using a...

Acromioclavicular (AC) joint injuries are common and often seen in contact athletes, resulting from a fall on the shouldertip with adducted arm. This joint is stabilized by both static and dynamic structures including the coracoclavicular (CC)ligament. Most reconstruction techniques focus on CC ligament augmentation as the primary stabilizer of the AC joint.The best surgical technique for some ...

The Escritoire is a horizontal desk surface that uses two overlapping digital projectors to create a foveal display – a large interactive surface that has a high-resolution area to accommodate the user’s focus of attention. In contrast to high cost, multi-projector display walls for group presentations or scientific visualization, it is an augmentation of the personal computer, designed for com...

We studied reach adaptation to a 30° visuomotor rotation to determine whether augmented error feedback can promote faster and more complete motor learning. Four groups of healthy adults reached with their unseen arm to visual targets surrounding a central starting point. A manipulandum tracked hand motion and projected a cursor onto a display immediately above the horizontal plane of movement. ...

The logarithmic conformal field theory describing critical percolation is further explored using Watts’ determination of the probability that there exists a cluster connecting both horizontal and vertical edges. The boundary condition changing operator which governs Watts’ computation is identified with a primary field which does not fit naturally within the extended Kac table. Instead a “shift...

The present work shows the results obtained from experimental investigations of the augmentation of turbulent flow heat transfer in a horizontal tube by means of mesh inserts with air as the working fluid. Sixteen types of mesh inserts with screen diameters of 22mm, 18mm, 14mm and 10mm for varying distance between the screens of 50mm, 100mm, 150mm and 200mm in the porosity range of 99.73 to 99....

Ionospheric disturbances are known to have adverse effects on the satellite-based communication and navigation. One particular type of ionospheric effects, observed during major geomagnetic storms and threatening the integrity performance of both ground-based and space-based GNSS augmentation systems, is the sharp increase/decrease in the ionospheric delay that propagates in horizontal directio...

UNLABELLED Backround: The aim of this study was to assess changes in bone volume after block bone augmentation and placement of dental implants and further evaluate the aesthetic outcome of the treatment. MATERIAL AND METHODS 9 patients with atrophied anterior maxilla were included in this study. They received total of 21 implants. Dimensions of the alveolar ridge were measured from cone-beam...
