Using CBCT-guided technology to facilitate indirect (crestal) sinus lift with immediate dental implant placement
Ridge resorption begins immediately after a tooth is removed. In the posterior maxillary arch, this bone loss is compounded by pneumatization of the maxillary sinus into the edentulous space. Even when ridge preservation is performed, the residual alveolar ridge may be deficient for dental implant placement due to inferior expansion of the sinus floor. This can be managed by the sinus lift procedure, either by lateral or crestal approach. Many techniques have been developed for the crestal sinus lift utilizing various osteotomes, bone compactors, and drilling systems with control devices to limit depth of penetration toward the sinus floor. This report describes a unique technique which utilizes CBCT guided surgery to develop a controlled osteotomy to accomplish a crestal sinus lift.
