Aim
The main objective of this research was to examine the outcomes of transcrestal sinus lift with simultaneous implant placement employing Osseodensification, in comparison to lateral sinus lifting methods. Patients and
Methods
Fourteen patients were enrolled in this clinical trial at the clinic of Oral and Maxillofacial Surgery Department, Faculty of Dental Medicine, Al-Azhar University. These patients were randomized allocated into two groups. Group I: Patients who underwent transcrestal sinus floor elevation procedures utilizing osseodensification. Group II: Patients who received treatment involving Lateral Maxillary Sinus Floor Elevation. CBCT scans were acquired immediately postoperatively and at the 6-month follow-up to assess bone height, bone gain, and bone density. Osstell was utilized to evaluate primary implant stability both during the initial placement and at the six-month follow-up. The length of the surgical procedure was meticulously recorded for every group.
Results
The findings indicated that Group I exhibited a mean bone height gain of 5.33 ± 0.83mm, whereas Group II showed a gain of 10.02 ± 1.82mm, with a significant statistical difference. The average implant stability quotient (ISQ) values for Group I was 80.00 ± 3.11, compared to 75.86 ± 2.91 for Group II, also showing a statistically significant difference.
Conclusion
Crestal maxillary sinus elevation with Osseodensification shows better bone density and implant stability than lateral lifting. Osseodensification is less invasive and time-consuming, making it a potential alternative to the lateral window technique.
