Introduction: Maxillary sinus lifting for dental implant placement is a well-known and versatile technique; new techniques have been presented based on the physiology of bone repair inside the maxillary sinus, now blood clot can be considered autogenous osteogenic graft material, into which osteoprogenitor cells can migrate, differentiate, and regenerate bone.
Objective: Evaluation of the effectiveness of graftless sinus lifting technique through lateral window with simultaneous placement of dental implant.
Patients and methods: Ten patients were selected to match inclusion and exclusion criteria. They were treated using graftless sinus lifting through lateral window technique with simultaneous implant placement. New bone formation was assessed radiographically by measuring bone height, bone volume, bone density and implant stability.
Results: In all treated cases bone volume and bone height increased significantly. Radiological and clinical follow-up was conducted throughout 6-months postoperatively. All patients showed successful bone formation beneath the schneiderian membrane.
Conclusion: Graftless sinus lifting with immediate implant placement is a predictable, time saving technique. Also it decreases the overall cost of the procedure and the complications that maybe encountered when using any bone substitutes.
