Horizontal Ridge Augmentation Before Placing Implants Using a Double-bone, Double Resorbable Membrane Technique: Two Clinical Cases.

Guided bone regeneration is a well established technique used for augmentation of deficient alveolar ridges. There is much evidence in the procedure. Multiple techniques have been introduced using various types of membranes and bone grating materials. However, efficacious regeneration requires both a high level of technical skills and a through understanding of major biological principles. This case report is presented to illustrate a reliable approach to successful management of two different alveolar defects.
