The keyword for the search was vertical augmentation and dental implant .The limitation forthis review was 10 years and dental journals.The number of literature reviewed was167 and the databases were Medline and Pubmed , with non-peer-reviewed articleseliminated as much as possible.  Results Several techniques have been developed to treat insufficient volume, but only fourof the most commonly performed are described. Three are frequently used: (1) sinusfloor elevation and (2) bone block graft, involving either a cortical or cortico-cancellousgraft and (3) GBR .The fourth is the technique of bone distraction, which is still indevelopment and may show promising results in the future because of its greatbiological pertinence.Depending on the implantation site, the morphology of the bone defect and thequantity of bone to be repaired determine the techniques used in oral surgery. Conclusion Many different techniques for reconstruction of bony defect exist for effective boneaugmentation. The approach is largely dependent on the extent of the defect and specificprocedures to be performed for the implant reconstruction It is most appropriate to usean evidence-based approach when a treatment plan is being developed for boneaugmentation cases.Key words: vertical augmentation, dental implant, bone substitute, bone graft,membrane    - 4 - I. Introduction As the prevalence of implants has increased, so has the challenge to augment theremaining osseous structure to house those implants. Therefore, lots of differentmethods for vertical bone augmentation have developed and the purpose of this articleis to review the existing methods and prognosis of that according to these respectivemethods.Several techniques have been developed to treat insufficient volume, but only fourof the most commonly performed are described. Three are frequently used: (1) sinusfloor elevation and (2) bone block graft, involving either a cortical or cortico-cancellousgraft and (3) GBR .The fourth is the technique of bone distraction, which is still indevelopment and may show promising results in the future because of its greatbiological pertinence.The expectations of dimensional gain and bone quality are unique to each technique,as well as the potential complications. Distraction osteogenesis has had the greatestpotential for vertical gain, while guided-bone regeneration and monocortical onlaygrafting achieve similar results and bicortal onlay graftin has better results thanmonocortical and GTR .The choice of procedure is to be based upon the patient's existing anatomy, degreeof vertical deficiency, and willingness to participate in treatment.Volume insufficiencyat the maxillary and mandibular incisors is usually related to a lack of thickness, whilemolar sectors more often present with height. Depending on the implantation site, themorphology of the bone defect and the quantity of bone to be repaired determine thetechniques used in oral surgery. The following question should be considered: in lightof the current information available, is a particular therapeutic approach adapted toreach the treatment objectives?
