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.

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...
