With this case report we demonstrate a new technique useful in augmenting alveolar ridges after resection procedures or atrophic loss of volume. The augmentation is done by means of a new osteogenic distractor (manufactured by ACE Surgical Supply Co., Inc., Brockton, MA, USA), the distraction procedure is according to Ilizarov's principles.

introduction in spite of multiple applications of bioactive glasses, these materials have not been evaluated yet for ridge augmentation. due to the large number of patients who need ridge augmentation and the benefits of nova bone, in comparison with other alloplasts, this study was fulfilled for evaluation of nova bone ability in ridge augmentation. methods the samples of this experimental stu...

In this article we consider the stochastic restricted ridge estimation in semipara-metric linear models when the covariates are measured with additive errors. The development of penalized corrected likelihood method in such model is the basis for derivation of ridge estimates. The asymptotic normality of the resulting estimates are established. Also, necessary and sufficient condition...

background and aims. autogenous onlay bone grafting is a common procedure for alveolar ridge augmentation. it has been suggested that the amount of healed bone after this technique would be significantly less than the initial quantity. the aim of this study was to determine the relationship between the various parameters influencing the outcome of ridge augmentation procedures. materials and me...

Background Dermatoglyphics could assist in the diagnosis of congenital abnormalities. The aim of this study was to identify the dermatoglyphic patterns (finger print pattern type, total ridge count of each finger, a-b ridge count, and articulotrochanteric distance [ATD angles]) in the parents of cystic fibrosis children. Materials and Methods We recruited 75 parents of children with cystic fibr...

In this paper we consider the problem of blood vessel segmentation in retinal images. After enhancing the retinal image we use green channel of images for segmentation as it provides better discrimination between vessels and background. We consider the negative of retinal green channel image as a topographical surface and extract ridge points on this surface. The points with this property are l...

The proposed ridge features are composed of four elements: ridge count, ridge length, ridge curvature direction, and ridge type. For extracting ridge features, we also define the ridge-based coordinate system in a skeletonized image With the proposed ridge features and conventional minutiae features(minutiae type, orientation, and position), we propose a novel matching scheme using a breadth-fi...
