1) Who is in control?
Our welcome post. It emphasized the responsibility the professional should have conducting his cases, especially in relation to the knowledge of the exact laws that govern all orthodontic appliances. We can never forget who is in control.

2) Physiological expansion
A much discussed, but still poorly understood question was raised in this post. Are there advantages of self-ligating brackets over conventional ones, regarding the physiological expansion of dental arches? A robust set of evidence shows that the magnitude of forces released, the type of tooth movement and degree of bone modeling during transverse expansion do not depend on the type of bracket.

3) Testing your Clinical Eye: Can you “read” the wire?
We have shown that the simple “reading” of the wire, or visual inspection, represents an incorrect method for predicting the forces systems delivered by an orthodontic archwire. In addition, we shared with you a reliable clinical tip to immediately recognize the presence and direction of forces in a “two-tooth” system. Check it here.

4 and 5) Equilibrium, your clinical life depends on this principle

One of the most essential topics of biomechanics. It was addressed in two posts. In part 1, we clarify fundamental concepts for understanding the topic, such as static equilibrium, activation and deactivation forces, and the correct interpretation of the law of action and reaction. In part 2, we explain how to recognize the requirements needed for the equilibrium condition. Since all appliances must meet this condition, the post helps the professional to take this first step for the rational and effective application of biomechanical principles in the clinical practice.

6) A greeting for professor Burstone
Faced with doubts and uncertainties about the future of our specialty, this post was a simple appeal to the study, application and sharing of the certainties that govern our clinical practice. After all, why so much eagerness to accelerate the dental movement, when in many cases it is not known how and where these teeth are moving?

7) Our First Online Course
We are glad to invite you to our first online course: Introduction to Orthodontic Biomechanics. We hope this course can help students and professionals to learn and consolidate the elementary concepts of physics applied to orthodontics, by using a scientific and creative approach.

Happy new year 2017!
