Abstract
When tooth is extracted because of deep caries, severe periodontal disease, trauma etc., alveolar ridge resorption will
happen inevitably. Mostly alveolar ridge resorption (vertical & horizontal) makes implant placement difficult. To improve
these defects, additional procedures such as GRB (staged or simultaneous approach), block bone graft or ridge splitting
is needed. Especially in case of severe horizontal bone loss but relatively maintaining a vertical ridge height (seibert
classification, class I), implant placement is universally done with Block bone graft or GBR. Unlike these two procedures,
the ridge splitting converts non-contained defect (dehiscence) to contained defect (self-space making defect) that are
favorable to healing. Also ridge splitting has advantages such as the maintenance of buccal bone plate and the active
topical metabolism during healing by intentional fracture. In these two cases, it is ascertained that implant placement with
ridge splitting procedure is effective in the severely atrophic alveolar ridge.
