Case planning and practicing in isolation may have been possible 20 years ago, but the contemporary dentist recognizes that there is too much at stake and too much to know to go it alone. Collaboration can open new prospects to many treatment options that may never have been thought of, and some of these options may fit the patients' desires better than anything one may think of presenting. Patients demand a higher level of dental care when combining treatments from different clinicians, as they are not only looking for function, but also for esthetics. A high percentage of adult patients show a combination of situations that make an interdisciplinary treatment plan necessary. In addition, there seems to be more credibility in the eyes of patients when a team of experts is consulting and collaborating on their case. The aspects of the various specialities and their interrelationship with each other along with the role of Interdisciplinary treatment planning as pertaining to the branch of Periodontology in the overall successful management of the patient is very well highlighted in this current edition of Lambert Publication.
