Volumetric Changes in Anterior Maxillary Reconstruction using DBBM Associated with PRF Membrane and Titanium Mesh - case series.

Aim: This study aimed to assess the horizontal and volumetric bone augmentation obtained by using deproteinized bovine bone mineral (DBBM) associated with platelet-rich fibrin (PRF) membrane and titanium mesh at anterior atrophic region of the maxilla. Materials and methods: Eight healthy patients requiring horizontal and vertical bone reconstructions were included. The amount of horizontal bone gain was measured on computed tomographic images and the thickness at three levels (7,11,13 mm from the crest) before and six months after reconstructive surgery. Each graft was plotted on sagittal image at the mid-face by using the OnDemand 3D Dental TM software and volumetric analysis was performed by using the InVesalius 3.0 software. Results: The initial height was 15.61 ± 4.3 mm and the final one was 17.94 ± 5.2 mm (p = 0.001), resulting in a gain of 2.33 mm and the initial thickness 5.962; 6.762; 7.918 (7,11,13 mm from the crest) change to 8.627; 10.05; 10.63 respectively. The volume increased 42.939± 16.856 mm3, which corresponds to a variation of 45 - 160%. depending on the defect. A total of 20 implants were successfully installed. Conclusion: The use of DBBM, PRF and titanium mesh is a safe choice with promising results. [ABSTRACT FROM AUTHOR]
