STUDY OBJECTIVES METHODS AND RESULTS
This report presents a two-stage approach for crestal sinus elevation using the osseodensification technique in a case of severe vertical bone deficiency (<3 mm). Traditional approaches to maxillary sinus elevation with less than 3 mm of residual bone height typically require a lateral window technique. A 55-year-old male patient presented with a missing maxillary right first molar with residual bone height of 2 mm. The treatment involved: Stage 1: Crestal sinus elevation using osseodensification with Versah burs and allograft placement. Stage 2: After 6 months of healing, placement of a Straumann Bone Level Tapered implant (4.1 × 10mm) with 35 Ncm insertion torque and final prosthetic restoration was started 4 months after implant placement. Then, follow-up at 12 months demonstrated stable peri-implant tissues, maintained bone levels, and excellent patient satisfaction. Radiographic evaluation showed uniform bone formation around the implant and maintained sinus floor elevation.
CONCLUSIONS
The case demonstrates that osseodensification can provide a predictable alternative to lateral window approaches even in cases with severe vertical bone deficiency (<3 mm), offering reduced invasiveness with enhanced bone density and favorable clinical outcomes.
