Powder synthetic materials have been regarded as a treatment alternative for restoring anatomy and function of bone deficient regions in the maxillofacial complex, especially prior to implant therapy. Objective: to physically/chemically characterize a ß-TCP powder. Methods: Three powder samples were used for each analytical tool. SEM was performed at various magnifications for powder morphology assessment. EDS at various accelerating voltages was used for elemental assessment. TEM specimens were prepared and analyzed at various magnifications. XRD spectra were obtained by scanning the powder from 10-110 2-theta at 0.05 degrees step size/ 5 sec step time, and were compared to theoretical crystallographic calculations. FTIR spectra were evaluated for the presence of P-O, P-O-H, and H-O-H alpha-TCP and ß-TCP characteristic bands. Surface elemental composition was evaluated by XPS Results: SEM revealed a porous granular microstructure of a wide particle size range without macrocontaminats. EDS showed Ca, P, and O, with stoichiometric values close to theoretical values. TEM analyses revealed multigrained particles and contamination absence. XRD spectra revealed the presence of ß-TCP peaks in agreement with theoretical calculations. The absence of bands (FTIR spectra) at 460 and 720 cm-1 added to the absence of an isolated band at ~600 cm-1 characteristic of alpha-TCP further indicated the absence of such phase. XPS revealed the presence of Ca, P, O, and adsorbed C at the powder surface. Conclusions: physico/chemical characterization showed a crystalline ß-TCP powder, without secondary phases, presenting undetectable contaminants, supporting favorable properties for its intended application.
