Recently, the use of implants in the elderly patients has been increasing the recovery of the edentulous area. This is due to an increase in the number of elderly people who maintain natural teeth compared to the past. In addition, the lower age of health insurance coverage for implants seems to have an impact. Older patients are often left with missing teeth, or due to chronic periodontal disease, alveolar bone of defect site is often lost. In particlar, in the maxillary posterior defect region, pneumatization of the maxillary sinus occurs and the alveolar bone for implantation is insufficient. Various techniques have been proposed to increase the remaining bone height, which is insufficient for placing the implant in the maxillary posterior defect area. The crestal approach and the lateral approach have been studied for a long time and are actively used. In this study, we discuss the advantages of the crestal approach compared to the lateral approach in elderly patients and report the case of implant placement with crestal approach using osteotomes in the case of lack of maxillary posterior alveolar bone.
