Immediate dental implantation after indirect sinus elevation using osseodensification concept: a case report

Area of Science:

• Dental Implantology
• Oral and Maxillofacial Surgery
• Bone Grafting Techniques

Background:

• Posterior maxillary implantation is challenging due to insufficient bone height and low bone density after sinus pneumatization.
• Osseodensification (OD) presents a novel, less invasive, and effective indirect sinus floor elevation technique.

Purpose of the Study:

• To evaluate the efficacy of osseodensification (OD) as a sinus floor elevation technique for dental implant placement.
• To assess the potential of OD as an alternative to direct sinus lift procedures.

Main Methods:

• A case presentation of a 52-year-old male with limited bone height (1-4 mm) in the posterior maxilla (teeth 16, 17).
• Treatment involved tooth extraction, internal sinus lifting and bone grafting using OD burs, followed by immediate implantation.

Main Results:

• Cone-beam computed tomography (CBCT) confirmed residual bone height of 1-4 mm and width of 9-12 mm.
• The procedure utilized osseodensification burs for internal sinus lifting and bone grafting prior to immediate implant placement.

Conclusions:

• Osseodensification (OD) is a promising technique for direct sinus floor elevation.
• The vertical bone gain achieved with OD in transcrestal sinus lifting can be comparable to external sinus lifting procedures.
