Abstract

This study is focused on development of ceramics-based different types of body implants like the spinal cord, femoral head, and elbow joints and dental implants. Due to low fracture toughness and high hardness, sintered stage machining is not preferable for ceramics. Advancement of gelcasting and protein coagulation casting of ceramics is promoting green stage machining in recent time due to their high green strength. Interestingly, custom design and fabrication are essential due to variation in size and shape of body implants of different peoples of crown like many other biomedical objects. The surface quality of the machined sample was evaluated through surface profilometry and optical imaging. The Computerized Numerical Control (CNC) machining parameters of diamond-coated tools for the manufacturing of dental crown were optimized for superior surface quality in a minimum time period. Finally, different ceramic implants of varied size and shape were fabricated and characterized by using different tools.
