This book covering the basic essentials of prosthetics gave no information in the wider fields of the subject. Also since no textbook can remain permanently up to date it was decided to revise certain sections and make some additions. The section on partial dentures has been largely re-written with many new illustrations. Several new chapters have been included dealing with perfecting the occlusion and articulation, obturators, appearance and overlay and implant dentures thus presenting in one volume all the essentials which a student should know before qualification and also making the book more useful to the practitioner. An experiment has been tried in this new edition with some trepidation - which is to drop the use of the term bite taking substituting where possible the word record taking as being more in keeping with modern teaching: time will show whether this change is justified or not.
