Bone mass (height and width) is one of the local factors that must be considered in implant repair. Trauma, infection, tumor, osteomyelitis surgery debridement, as well as various congenital factors will to varying degrees destroy the integrity of alveolar bone structure and morphology, resulting in simple planting can not meet the repair requirements.
