Critical Size Bone Defect Healing Using Collagen–Calcium Phosphate Bone Graft Materials
Fig 4
Fourier Transform Infrared Spectroscopy and X-ray Diffraction.
Fig 4a The FTIR spectra for the calcium phosphate portions of the graft are shown in the top panel. The Sorrento Bone Graft Substitute (red) and Vitoss Foam Strip (Grey) compared well to each other were both similar to the tricalcium phosphate control (Blue) and differed compared to the hydroxyapatite control (green) [55]. The FTIR spectra for the organic portions of the graft are shown in the bottom panel. The Sorrento Bone Graft Substitute (red) and Vitoss Foam Strip (Grey) compared well to each other were similar to the Collagen control (Blue). The typical amide peaks of collagen were present in all samples [54]. There was however evidence of the calcium phosphate residual material as evident by the phosphate peaks at approximately 1100–950 cm-1. Fig 4b The XRD diffraction patterns for the calcium phosphate portions of the graft are shown in the top panel. The Sorrento Bone Graft Substitute (red) and Vitoss Foam Strip (Grey) compared well to each other were both similar to the tricalcium phosphate control (Blue) and differed compared to the hydroxyapatite control (green) [55].
