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.

Abstract Causality is an important element in decision-making and interventions are required to optimize results of target values. In this paper, based on the model Causal Bayesian Optimization, a counter-noise version acquisition function proposed new prior estimation algorithms including Support Vector Regression, Ridge Regression Random Forest evaluated. This paper provides improved framewor...

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...

As the uneven distribution of contrast agents and the perspective projection principle of X-ray, the vasculatures in angiographic image are with low contrast and are generally superposed with other organic tissues; therefore, it is very difficult to identify the vasculature and quantitatively estimate the blood flow directly from angiographic images. In this paper, we propose a fully automatic ...

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...

We study the problem of high-dimensional variable selection via some two-step procedures. First we show that given some good initial estimator which is l∞-consistent but not necessarily variable selection consistent, we can apply the nonnegative Garrote, adaptive Lasso or hard-thresholding procedure to obtain a final estimator that is both estimation and variable selection consistent. Unlike th...

High dimensionality causes problems in various areas of statistics. A particular situation that rarely has been considered is the testing of hypotheses about multivariate regression models in which the dimension of the multivariate response is large. In this article a ridge regularization approach is proposed in which either the covariance or the correlation matrix is regularized to ensure nons...
