Microwave-assisted casting is an innovative manufacturing technique that employs microwave energy to melt and shape materials. This process ensures uniform and volumetric heating, yielding superior products with enhanced mechanical characteristics. Moreover, it is a faster, energy-efficient, and environment-friendly manufacturing method. Titanium (Ti) and its alloys are extensively utilized for implantology in dental applications as a result of their biocompatibility and versatile properties. The properties of Ti get refined when exposed to microwave radiation. Recently, microwave casting of such biomaterials has gained attention from researchers as a method for developing cost-effective and superior bioimplants. This chapter presents an insight into fundamentals of the microwave-assisted casting technique. It highlights the application of this innovative technique in casting biomaterials for dental implants. The impact of various process parameters is discussed, in addition to issues and possibilities linked to the microwave casting of biomedical implants.
