The book "Spark Erosion Process in Dentistry: An Overview" provides a comprehensive introduction to the application of the electrical discharge machining (EDM) process in dentistry. It highlights the advantages of modern precise laboratory techniques compared to traditional methods and explains how EDM, a non-conventional industrial technique, has gained importance in dental practice since the 1990s. By using electrical discharges for material removal in a controlled liquid medium, this process allows for the creation of ideal and precise restorations. The author, Liju Jacob Jo, imparts in-depth knowledge about the functioning and specific applications of spark erosion in dentistry, making it a valuable resource for professionals and students in this field.
