Book: "Color Atlas of the "en bloc" Movement using GUMMETAL wire" by Shin Hasegawa

“Color Atlas of the "en bloc" Movement using GUMMETAL wire” by Dr. Shin Hasegawa is a comprehensive clinical guide to applying GUMMETAL, a revolutionary beta-titanium alloy, in orthodontic treatment. GUMMETAL possesses unique properties — a super-low Young's modulus and high strength—allowing it to function similarly to rubber with a strong shape-memory effect.

Key Aspects of the Book and GUMMETAL Technique:

• "En Bloc" Movement: The book focuses on using GUMMETAL for the efficient, simultaneous movement of teeth ("en bloc"), which can significantly reduce total treatment time compared to traditional methods.
• Clinical Application: Dr. Hasegawa details the practical use of GUMMETAL in a dental office, covering bracket positioning, vertical control, and specific bending methods for the main archwire.
• Malocclusion Management: The book provides case studies demonstrating the use of GUMMETAL for various conditions, including Angle Class I, II (divisions 1 and 2), and III, as well as open bites, lateral mandibular deviations, and partial corrections.
• Material Advantages: GUMMETAL allows for 3D control of tooth movement from the early stages of treatment, is biocompatible (nickel-free), and provides a gentle, constant force that reduces patient discomfort.

The book is characterized by abundant illustrations and clinical case photographs to guide practitioners through this new-age orthodontic technique.
