Twin Block Functional Therapy: Applications in Dentofacial Orthopedics

Since the last edition, new research has provided convincing evidence to support the value of functional orthopedic techniques. Research has now established that Twin Blocks influence the functional environment of the developing dentition and produce significant improvements in the pattern of facial growth and dental arch development. This latest and third edition contains important new sections to illustrate improvements and to advance our knowledge of Twin Block technique and other related aspects of functional therapy. Some of the topics that have been included in the latest edition are pitfalls in appliance design and management, explained with examples of problem patients and contraindications for functional therapy. The author has developed and tested Fixed Twin Blocks for the past 15 years and treatment records show the evolution of this technique, leading to a final solution with an improved design and protocol to integrate Fixed Twin Blocks with fixed appliances. There is also a discussion on Invisible Twin Blocks with preformed occlusal blocks present as a patient-friendly approach to the treatment of sleep apnea, with the added advantage of correcting Class II malocclusion. This new edition provides “state-of-the-art” instruction in all aspects of functional therapy, including diagnosis, case selection, appliance design, and clinical management.
