The Magdalena Ridge Observatory Interferometer (MROI) is a US federally funded project to construct the world’s most ambitious optical/IR (0.6-2.4micron) imaging interferometer at a 10,500ft-altitude site in New Mexico. In its initial phase it will consist of 6 telescopes, each 1.4m in diameter, separated by distances ranging from 7.5m to 340m. A second phase will upgrade the interferometer to ...

Materials and methods This study included 300 human adult skulls, which were obtained from the Forensic Osteology Research Center, Faculty of Medicine, Chiang Mai University. The metopic suture and supraorbital ridge were observed macroscopically. The degree of supraorbital ridge was classifi ed into 4 levels. The 1st level had a massive prominence, the 2nd showed fair prominence, the 3rd indic...

BACKGROUND Localized alveolar ridge defect may create physiological and pathological problems. Developments in surgical techniques have made it simpler to change the configuration of a ridge to create a more aesthetic and more easily cleansable shape. The purpose of this study was to compare the efficacy of alveolar ridge augmentation using a subepithelial connective tissue graft in pouch and m...

BACKGROUND Following loss of teeth, atrophy of alveolar ridge of the jaws is a substantial problem and unintended outcome that compels clinicians to perform bone reconstruction ahead of implant placement. Although autogenous bone is recommended as the gold standard in bone reconstruction, aninvasive second surgery harvestinga limited volume of bone (from intraoral source) has led a significant ...

careful treatment planning, space management, augmentation of bone and attention to the details of implant surgical and prosthetic techniques are important factors when treating anterior maxilla specially replacement of missing teeth. this case report addresses a chair-side ridge augmentation procedure using autograft bone harvested with trephine drills and placed without using screws and the f...

An adequate amount of bone all around the implant surface is essential in order to obtain long-term success of implant restoration. Several techniques have been described to augment alveolar bone volume in critical clinical situations, including guided bone regeneration, based on the use of barrier membranes to prevent ingrowth of the epithelial and gingival connective tissue cells. To achieve ...

Discussed is a procedure being developed for the clinical assessment of children's phonological patterns. Reviewed are recent developments in the psycholinguistic/sociolingUistic literature which support the basic criteria for the new procedure (such as the provision for child phonology rather than adult phonology). The significance of contextual influences is stressed, and the linguistic and c...

New experimental laboratory data are presented on swash overtopping and sediment overwash on a truncated beach, approximating the conditions at the crest of a beach berm or inter-tidal ridge-runnel. The experiments provide a measure of the uprush sediment transport rate in the swash zone that is unaffected by the difficulties inherent in deploying instrumentation or sediment trapping techniques...

Bone morphogenic proteins (BMP) are members of the family of transforming growth factors. Fifteen different BMP have been identified, all with varying degrees of cellular activity, including cartilageor bone-inductive properties. Two recombinant proteins are available: recombinant human bone morphogenetic protein (rhBMP)-2 and rhBMP-7. These products have been investigated as alternatives to au...

PURPOSE Autogenous bones are frequently used because of their lack of antigenicity, but good osteoconductive and osteoinductive properties. This study evaluated the biological behavior of perforated and nonperforated cortical block bone grafts. METHODS Ten nonsmoking patients who required treatment due to severe resorption of the alveolar process and subsequent implant installation were inclu...
