Abstract
This article focused on the comparative study of the physicochemical properties of bovine and human bio hydroxyapatites with commercial samples used in dental implants. Raw and defatted bovine bone was calcined at 560 °C, while commercial samples were analyzed without any processing (RTR, Novabone®, and Nukbone® granules). Transmission Electron Microscopy and Scanning Electron Microscopy were used to study their crystal size and morphology. Thermogravimetric analysis was used to study the decomposition and transformation of the organic and inorganic phases. The crystalline phases and Full Width at Half Maximum were determined by X-ray. Infrared and Raman spectroscopies were used to determine the presence of organic materials. Results showed the presence of organic material in some commercial samples, which means that these biografts could have immunological reactions with the patient.
