Implant Insertion in the Presence of Bone Islands in the Maxillary Sinus: A Case Report

Bone islands in the maxillary sinus are rare, and no established guidelines exist for implant surgery in their presence. This case report presents an approach to implant surgery utilizing bone islands in the maxillary sinus. In this case, we utilized the bone island, performed osteotome sinus floor elevation combined with concentrated growth factor (CGF), and simultaneously inserted a Straumann Soft Tissue Level implant for a 56-year-old male patient. Based on 1-year follow-up examinations and cone beam computed tomography (CBCT) images, the approach yielded favorable outcomes. Utilizing bone islands in the maxillary sinus during implant surgery appears effective, but longer-term follow-up and additional cases are needed to validate this approach.
