🟣 New video: Anchorage in Orthodontics

How does the size of the Target Unit influence anchorage loss?
Based on Newton’s Second Law, even with the same force, changing the Target Unit can significantly affect how the Anchor Unit responds.

A key concept with direct clinical implications when planning multi-tooth movement.

🟣 In our latest video, Dr. Alikhani continues the discussion on Anchorage in Orthodontics.

This session explores how the size of the Target Unit influences movement of the Anchor Unit, even when force and anchorage remain unchanged — a concept with important clinical implications when moving multiple teeth.

He also introduces the role of time and rate of movement, highlighting how small decisions can significantly impact anchorage loss during space closure.

🟣 In our latest video, Dr. Alikhani continues the anchorage discussion in Part 3 of the series.

This session focuses on another strategy to reduce movement of the anchor unit: differential forces. With a brief review of the biology of tooth movement and simple illustrations, Dr. Alikhani explains how elastics can optimize the force applied to the Target unit while minimizing the forces on the Anchor unit.

While widely used to reduce anchorage loss, this approach must be applied carefully to avoid unintended side effects.

🟣 In our latest video, Dr. Alikhani continues the discussion on Anchorage in Orthodontics, focusing on strategies to reduce movement of the anchor unit.

Through simple illustrations, he explains how—even though orthodontic tooth movement is biologic—Newton’s laws of motion still apply. This session highlights a key clinical principle: increasing the size of the anchor unit as a common approach to minimizing anchorage loss.

🟣 In our latest video, Dr. Alikhani launches a new series of episodes focused on one of the most fundamental concepts in orthodontics: Anchorage.

This first session introduces essential physics principles, defines Anchor and Target units, and reviews the different levels of anchorage required for precise, personalized mechanotherapy. Understanding reaction forces and anchorage demands at each stage of treatment is critical to achieving predictable outcomes.

🟣 In this video, Dr. Alikhani reviews a facial trauma case complicated by delayed orthodontic follow-up after hospitalization, which resulted in tooth ankylosis and an open bite.

Against the common belief that ankylosed teeth cannot be treated, he presents a CTOR Ortho approach that includes subluxation of the ankylosed tooth and forced eruption using precise mechanotherapy—achieving stable anchorage, open bite closure, and an ideal occlusion.

Watch the latest episode — link in our stories.

🟣 In this new video, Dr. Alikhani reviews the craniofacial and functional implications of Nemaline rod myopathy (NM), a rare congenital myopathy. Altered muscle function in NM can lead to significant challenges — including skeletal open bite tendencies, deep palate with thick mucosa, flaccid soft palate without proper nasal seal, swallowing difficulties, tongue-thrust patterns, and reduced condylar and coronoid development.

Understanding these neuromuscular effects is essential for planning orthopedic and orthodontic care, highlighting the need for interdisciplinary collaboration, tailored treatment strategies, and adequate neuromuscular adaptation time.

🟣 A new Biology of Orthodontics video is now available on CTOR’s YouTube channel.

Dr. Mani Alikhani presents findings from a clinical trial examining how age affects the biological response to orthodontic forces. The study shows that beyond a certain threshold, increasing force does not enhance tooth movement—both adolescents and adults reach a saturation point, though adults reach it sooner.

These results highlight the need to individualize force levels in orthodontic treatment based on biological response rather than magnitude alone.

🟣 CTOR Press at IADR 2025!
Our CEO, Dr. Chinapa Sangsuwon, represented CTOR Press at the IADR General Session in Barcelona, where she hosted the Orthodontics Research Group business meeting in her role as Secretary and Treasurer. This international group connects clinicians and scientists dedicated to advancing orthodontic research.
Dr. Sangsuwon also had the honor of presenting this year’s CTOR Press INNOVATION Award for Excellence in Orthodontics Research — a recognition of outstanding contributions by early-career professionals working to shape the future of our field.
