Direct Sinus Lift with Immediate Implant Placement- A Modality in Atrophied Maxilla: A Case Report

The pneumatization of the maxillary sinus poses challenges for oral implantologists due to its natural expansion into the maxillary bone, often exacerbated by tooth loss. This reduces available bone for implant placement in the posterior maxilla, necessitating augmentation techniques to facilitate successful implantation. This article presents the case of a 23-year-old female with severe tooth decay in the left maxilla, desiring implant replacement. Cone-beam computed tomography (CBCT) revealed inadequate bone height (3.3 mm) complicated by sinus pneumatization. Surgical intervention involved tooth extraction followed by direct sinus augmentation with a bone graft to stimulate osteogenesis. Simultaneously, an implant was placed. Follow-up CBCT examination occurred at the 4-month interval. At the 4-month follow-up, CBCT examination demonstrated a significant increase in vertical bone height to 12.4 mm, indicating successful bone regeneration and implant stability. The case highlights the importance of a comprehensive diagnostic approach and strategic surgical planning in managing sinus pneumatization-related challenges for implant placement. Direct sinus augmentation combined with bone grafting proved effective in achieving sufficient bone height for implantation. This underscores the significance of appropriate therapeutic interventions and postoperative monitoring for favorable outcomes in such cases.
