Study of guided bone regeneration in alyeolar ridge augmentation

Due to partial or systematic reasons,long term teeth deficiency can break the dynamic balance of osteogenesis and osteo-destruction.The dental alveolar ridge may be absorbed and atrophied to a low,narrow and notched shape,just like an edge.as a result,the attachment plate between the base and the dental alveolar ridge is decreased and can affact retention and stability of the denture.It is difficult to achieve the goal of mastication function rehabilitation.So to augment dental alveolar ridge by surgical operation is one of the most important tasks of denture preposthetic surgery.We thus review an assay about guided bone regeneration(GBR) in surgery repair technique.
