Two-Stage Crestal Sinus Elevation Using Osseodensification Technique for Single Molar Restoration: A Case Report

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Severe vertical bone deficiency (<3 mm) in the maxilla typically necessitates invasive lateral window sinus elevation techniques.
• The case involved a 55-year-old male patient with a 2 mm residual bone height in the maxillary right first molar region.

Observation:

• A two-stage crestal sinus elevation was performed using the osseodensification technique with Versah burs and allograft.
• Following 6 months of healing, a dental implant was placed, with prosthetic restoration initiated 4 months later.
• A 12-month follow-up assessed peri-implant tissue stability, bone levels, and patient satisfaction.

Findings:

• The osseodensification technique resulted in uniform bone formation around the implant and maintained sinus floor elevation.
• Stable peri-implant tissues and maintained bone levels were observed at 12 months.
• The procedure demonstrated excellent patient satisfaction.

Implications:

• Osseodensification presents a predictable and less invasive alternative to the lateral window technique for maxillary sinus elevation, even in cases of severe vertical bone deficiency.
• This approach enhances bone density and leads to favorable clinical and radiographic outcomes.
• The findings support osseodensification as a viable option for complex implant cases requiring significant bone augmentation.
