Designing is the most important and most difficult phase in Removable Partial Denture construction. Even though designing is a dentist activity, many of the them badly depend on laboratory technologist for designing. This may be attributed to the issues related to conceptual clarity. Through this textbook, I am trying to demystify various grey areas related to the designing aspect of removable partial dentures. This textbook presents a novel, innovative and simple 'quadrant driven approach' for the design process, which am sure will benefit everyone who wants to master the art of designing. This textbook reflects a collage of thoughts and concepts which was developed during my clinical and academic career. That is the reason behind using hand drawn illustrations in this textbook. I am sure this textbook will stimulate creative thoughts in every reader.
