Abstract
Several techniques such as onlay block bone grafting, guided bone regeneration, ridge split technique/ridge expansion technique, distraction osteogenesis and etc. were performed to form sufficient alveolar buccolingual width for implant insertion in narrow alveolar ridge. Ridge split technique was recognized as very useful method for expansion the narrow edentulous ridge and implant placement simultaneously. Ordinary ridge split technique consists of splitting the vestibular (horizontal) and buccal (vertical), displacing the vestibular cortical bone by greenstick fracture, separating from the bone marrow and creating a middle gap for implant insertion. We mostly can expand the alveolar bone in ridge area through this technique. However, in some cases, the alveolar bone is thinner in apical area than ridge area, especially in maxillary incisior and premolar area. In these cases, performing the ordinary ridge split technique can cause the perforation of apical alveolar bone when drilling or placement of implant. We performed the different ridge expansion technique with apical osteotomy locally in narrow maxillary premolar edentulous area and implant insertion simultaneously for prevention of the perforation. So, we report this case with a review of literature.
