Implants placed simultaneously with maxillary sinus floor augmentation in the presence of antral pseudocysts: Presentation of a case series

Objective: To report the outcome of simultaneous placement of dental implants with maxillary sinus elevation in the presence of antral pseudocysts. Method and Materials: This case series involved 14 patients with 28 implants placed simultaneously with maxillary sinus elevation. The psuedocysts were treated by cystic fluid extraction. Postoperative examinations were performed at 3, 6, and 12 months. Results: All restorations were finished 6 to 9 months after implant placement. Nine antral pseudocysts disappeared and five decreased in size. All implants were deemed successful at 1 year postoperatively, showing osseointegration and masticatory function. No mobility was found during the follow-up period. Conclusion: In the absence of maxillary sinus infection, the combination of cystic fluid extraction, maxillary sinus elevation, and immediate implantation showed an acceptable clinical outcome in this series of patients.
