Abstract:
Implantation in the posterior maxilla is more challenging due to the insufficient bone height after maxillary sinus pneumatization and the low bone density. Osseodensification (OD) is considered a novel, less invasive, and more effective indirect sinus floor elevation technique.
Case Presentation:
A 52-year-old male presented to the oral and maxillofacial surgery department with a main complaint of chewing difficulties in the right posterior area maxilla (teeth numbers: 26 and 27). A cone-beam computed tomography (CBCT) imaging showed that the residual bone height ranged between 1 and 4 mm and the width ranged between 9 and 12 mm in the area of teeth numbers 16 and 17.
Intervention And Outcome:
The treatment plan was to extract the teeth (numbers: 16 and 17) and conduct internal sinus lifting and bone grafting using the OD burs with immediate implantation.
Clinical Discussion:
OD is proposed as an alternative procedure to the direct (lateral window) sinus floor elevation procedure. The amount of vertical bone gain obtained by this technique in transcrestal sinus lifting can be the same as external sinus lifting in this case.
Conclusion:
OD can be considered a promising technique for direct sinus floor elevation, considering the amount of vertical bone gain obtained by this technique.
