The Cause & Cure
of Malocclusion
Discover the root cause of crooked teeth and natural solutions. Prof. John Mew’s definitive guide to Orthotropics, facial growth, and malocclusion.
Research Based
Includes the famous Twin Studies
Malocclusion is a Postural Deformity
Modern orthodontics excels at straightening teeth, often using mechanics that retract the dentition. John Mew argues that while this aligns the teeth, it often fails to address the underlying cause.
The book posits that modern lifestyle factors—specifically soft diets, mouth breathing, and low tongue posture—cause the maxilla (upper jaw) to drop and narrow.
The Solution: Treat the cause, not the symptom. By correcting oral posture and muscle tone, we can influence the trajectory of skeletal growth.
Inside the Textbook
A rigorous academic manual designed for professionals and informed individuals seeking to understand the mechanics of facial growth.
The Tropic Premise
A rigorous examination of why modern faces are growing vertically. Understand the biological link between muscle tone, tongue posture, and skeletal development.
Reading the Face
Master Chapter 4, the definitive guide to facial analysis. Learn to objectively measure facial growth using the Indicator Line and Cheek Line.
Biobloc Orthotropics
A complete technical manual for the "Cure." Detailed instructions on the design, adjustment, and management of Biobloc appliances (Stage 1 through 4).

The Twin Studies: Environmental Influence
Chapter 6 presents one of the most compelling arguments for Orthotropics: a longitudinal study of monozygotic (identical) twins treated with different modalities.
The book provides visual and cephalometric evidence comparing traditional retractive mechanics against forward growth guidance.

About The Author
Prof. John Mew is an orthodontist and the originator of the philosophy of Orthotropics. A controversial figure in the dental community for his outspoken critique of extraction and retraction mechanics, his work has sparked a worldwide debate.
He argues that the aim of treatment should not merely be straight teeth, but the optimization of the facial skeleton and the preservation of the airway. This book is the culmination of his life’s research.
