Abstract
The CAD/CAM technology has played a significant influence in the growth of the dental prosthesis business in recent years. Nonetheless, due to a lack of competitive technologies that support dental application materials such as all-ceramic and porcelain material, additive manufacturing technologies have a weak penetration in this field of application. As a result, the primary purpose of this work is to characterise dental prostheses made of nano-fluorapatite glass-ceramic (NFGC) and fabricated by Shell Sintering Technology (SST). The main and secondary effects of manufacturing parameters on geometry accuracy, material strength, were demonstrated using a multivariable method. The study demonstrated that the proposed method is suitable for fabricating dental prostheses, with the optimal sintering parameters being 700 °C and 30 min holding time. Furthermore, the flexural strength of materials was found to range between 55 and 65 MPa, with shrinkage ranging between 10 and 14 %.
