background: several grafting materials have been used for alveolar ridge augmentation. the literature lacks researches to compare cenobone to other grafting materials. the aim of this study was to compare cenobone/cenomembrane complex to bio-oss/bio-gide complex in lateral alveolar bone augmentation in terms of radiographic, histologic, and histomorphometric parameters. materials and methods: i...

In this paper, a novel hierachical fingerprint matching method is proposed through using the minutiae and ridge image. The ridge-based matching is complementary to the minutiae-based matching for the purpose to reduce the false matching. The ridge matching is only accomplished in the area of the convex hull constructed by those matched minutiae in the phase of minutiae-based matching. Experimen...

Abstract—A relative efficiency is defined as Ridge Estimate in the general linear model. The relative efficiency is based on the Mean square error. In this paper, we put forward a parameter of Ridge Estimate and discussions are made on the relative efficiency between the ridge estimation and the General Ridge Estimate. Eventually, this paper proves that the estimation is better than the general...

In this paper we modeled and analyzed the ridge type InGaAlAs/InP semiconductor laser with lateral current confinement structure, and optimized the design for the ridge wave guide with the current confinement. We proposed and fabricated the ridge type InGaAlAs/InP laser with a cost effective selective undercut etching method and demonstrated the improvement of the ridge laser performance. This ...

Geological mapping of the area around Baltis Vallis, the longest (6,800 km) canali-type channel on Venus, has led to the determination of stratigraphic relations which appear to be consistent over this entire region comprising -20 x 106 km 2 or -5% of the total surface of Venus. The most abundant unit in the study area, plains with wrinkle ridges (Pwr), consists of two subunits separated by the...

The defects of the alveolar ridge can result from various causes, most common being the collapse of alveolar bone during extraction. Localized defects of alveolar crest impair prosthetic rehabilitation due to poor emergence profile of function. Several alternatives have been proposed to restore the damaged ridge by hard and soft tissue augmentation. Various soft tissue ridge augmentation techni...
