One of the most common challenges faced by the dental professionals is resorbed alveolar ridges which can be in horizontal and vertical dimension . Alveolar distraction osteogenesis is one of the mode of treatment for improving the deficient areas of alveolar ridges.
Alveolar distraction osteogenesis is biological process which involves progressive incremental traction between the vascularized bone segments in order to gain new bone formation. Osteotomy is usually performed which is followed by placing a osteo-distractor device which controls the separation process. By using this technique, the use of bone graft can be avoided as it produce same character and morphology of bone. It results into growth of the soft tissue with development of new bone on deficient ridge. As bone height is restored by this technique ,it is feasible to place longer dental implants. 
This review discuss about ride augmentation and various procedure which are performed to restore resorbed alveolar ridge. It emphasize on importance of alveolar distraction osteogenesis with some history of the technique on the basis of evidences available.
To conclude, distraction osteogenesis is an efficient method to restore the alveolar ridge height for better adaptability of dental implants.

Dimensional variations in the alveolar ridge after extraction often negotiations on achieving adequate  implant stability and placement of implants in the right prosthodontic positions. These circumstances request augmentation of the residual ridge to accomplish successful implant placement and long-term survival. Vertical Ridge Augmentation  is accomplished using both hard and soft tissue grafting procedures that intend to augment the alveolar ridge volume beyond the existing skeletal envelope; they are usually performed at the edentulous site of a deficient alveolar ridge . Although there are a large variety of alveolar ridge augmentation techniques with various degrees of success,  this review concentrate on vertical ridge augmentation using guided bone regeneration, autogenous block and alveolar distraction osteogenesis . Vertical ridge augmentation  procedures before or during dental implant placement are technically challenging and often encounter procedure-related complications. To minimize complications and promote success, a literature search was conducted to validate procedures used for Vertical Ridge Augmentation. A decision tree based on the amount of additional ridge height needed (<4, 4 to 6, or > 6 mm) is developed to improve the procedure-selection process. A decision tree guides selection of the most appropriate treatment modality and sequence for safe, predictable management of the vertically deficient ridge in implant therapy. Though the available literature speaks of an excess of methods and agents for ridge augmentation, there is a comparative scarcity of quality evidence to guide the selection of suitable techniques and material. Henceforth, this paper is an endeavor to develop and describe an evidence-based decision pathway for the selection of suitable techniques for various clinical situations. Additionally, a descriptive overview of various techniques and materials is presented.
