Immediate Implant Placement in the Esthetic Zone using the “Socket-Shield Technique”: A clinical Report

This paper presents the characterization of two( Ba .Ca .B . ) ( Ti .Zr .)O glass samples with the composition 40.0BaO+5.0CaO+5.0B2O3+45.0TiO2+5.0ZrO2(BBCZT) using various techniques.The two samples were produced through the melting quenching technique with two different methods.XRD analysis showed that both samples are amorphous.The glass network structure was analyzed using FT-IR spectroscopy, which enabled the identification of the functional groups and vibrational modes associated with the chemical bonds within the material.By applying Archimede's principle, the density ( ) and molar volume ( ) of the samples were evaluated.It was observed that the density of one of the samples increased (4.089 -4.260 g/cm 3 ), which was attributed to the conversion of BO (81.98%) to BO (89.73%) units in the material.Optical spectra were obtained to determine the optical energy gap ( ) (2.848 eV -3.028 eV) and Urbach's energy (E) (0.262 eV -0.247 eV), which were found to vary between the two samples due to differences in their preparation methods.The linear refractive index ( ), the dielectric constant (), the molar refraction ( ), the molar polarizability ( ), and the metallization criterion ( ) were also calculated to understand the optical characteristics of the two samples.
