The term Temporomandibular disorder's (TMD) covers constellation of conditions. There have been many attempts to categories these conditions but all have shortfalls. Some classify by anatomy, some classify by etiology and some by frequency of presentation. We should be aware, however, that there is considerable overlap in any classification system because these are often not clinically appropriate. No one system, therefore, satisfies all criteria. Temporomandibular disorders effect the articulatory system, consisting of temporomandibular joints, mandibular muscles and the occlusion. Any factor that has an effect on one part of the system is likely to influence the other parts of the system, so it is important to avoid tunnel vison when considering possible signs and symptoms of the Temporomandibular Disorder. In modern dental schools there is a shift from traditional teaching to more interactive methods. In classical didactic textbooks, readers are frequently seen as passive recipients, without any engagement in the learning process. Problem based learning increases the effectiveness of delivering information and makes learning a more memorable experience for the reader.

Loss of teeth causes difficulty in mastication and speaking which requires replacement to provide lost function and esthetics as well as psychological benefit.A prosthodontist must combine his skills in the field of Prosthodontics, Periodontics and Restorative dentistry to restore a dentition effectively. He must be capable of making an accurate diagnosis, which includes condition of remaining teeth, their supporting structures, occlusal relationship of teeth and articulation of jaws. All these factors play a very important role in replacement of missing teeth by prosthesis that include precision attachments. Unfortunately, most often precision attachments are chosen from descriptions in commercial catalogues. A dentist must base his techniques on both sound biological principles and mechanical considerations. Then precision attachment becomes what it should be, a beautiful example of bio-engineering that will be compatible with the continuing health of masticatory apparatus. I hope that this book will help the reader anticipate problems, overcome obstacles and master the basic technique of attachment retained denture construction - the rest will follow.
