Bone Volume Changes After Sinus Floor Augmentation with Heterogenous Graft
Summary
Deproteinized bovine bone showed increased volume after sinus augmentation in critical defects. This study evaluated volumetric stability using cone beam computed tomography (CBCT) and 3D analysis over eight months.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Dentistry
- Biomaterials Science
Background:
- Sinus augmentation is crucial for dental implant placement in the posterior maxilla.
- Graft material stability is essential for successful long-term outcomes.
- Deproteinized bovine bone is a commonly used bone graft material.
Purpose of the Study:
- To evaluate the volumetric stability of deproteinized bovine bone.
- To assess graft volume changes after sinus augmentation using cone beam computed tomography (CBCT).
- To analyze three-dimensional (3D) volumetric changes over an eight-month period.
Main Methods:
- Retrospective analysis of 13 patients undergoing sinus elevation with deproteinized bovine bone.
- Volumetric analysis of CBCT scans using InVesalius 3.0 software.
- Scans were taken immediately post-surgery (T1) and 8 months later (T2).
Main Results:
- All patients demonstrated an increase in bone volume (mean 9.10%).
- Mean bone volume increased by 0.137 cm³ from T1 to T2.
- A statistically significant correlation between bone volume and time was observed (P < .0001).
Conclusions:
- Deproteinized bovine bone exhibited volumetric increase after sinus augmentation in critical defects.
- The findings suggest favorable volumetric stability of this graft material.
- Further research with larger samples is warranted.
