Over last few decades "the facebow", which is the basic instrument in dentistry, have undergone lots of changes in their design, due to which it is real difficult to read about them in a single book. This book is a review about the basics of the facebow and is written basically for the undergraduates dental students, keeping in mind that it will help them understand facebow in a better way. I hope it will provide enough knowledge to them regarding the facebow.
