TY - JOUR ID - TI - Simultaneous Indirect Sinus Lift and Implant Insertion. Case Report for Extreme Bone Resorption AU - Faaiz Alhamdani PY - 2018 VL - 5 IS - 2 SP - 26 EP - 31 JO - Journal of Oral and Dental Research مجلة طب الفم والاسنان SN - 23106417 AB - Background Sinus lift is the procedure performed to overcome shortage in alveolar bone height in posterior maxilla. Objectives Alveolar bone shortage occurs due to maxillary sinus pneumatization after tooth extraction. This might interfere with primary implant stability. Materials and Methods There are two methods to elevate the sinus membrane for better accommodation of dental implant without jeopardizing the Schniderian Membrane. Direct (lateral) Approach and indirect (crestal approach). Direct approach is preferable when bone height is less than 4 mm, whereas indirect sinus approach is more suitable for cases with ≥ 5 mm bone height. However, excessive sinus pneumatization remains a challenge even for cases with direct sinus approach. Such cases require two step procedures for implant replacement. Results It seems unlikely to achieve sinus lifting and direct implant placement for cases with extreme alveolar bone height shortage in the same surgical procedure. Conclusion In this case report indirect sinus lift has been performed utilizing IBS® CMC Technique and IBS thread design to perform one step bone implant placement for alveolar bone height of 0.5 mm.
