Charles Tweed and why is he still important?
Today is the birthday of a great American orthodontist, Dr. Charles Henry Tweed. He was born on June 24, 1895. In the early 1940s, he established a study course which has been alive and kicking to the present day. Three times per year enthusiastic orthodontists from all over the world flock to the Charles Tweed International Orthodontic Foundation in Arizona to learn the fundamentals of diagnostics and treatment planning that were developed by Dr. Tweed.
Tweed’s Orthodontic Landscape
Dr. Tweed was initially mentored by Dr. Edwrad Harltley Angle, a charismatic and financially prosperous orthodontist who invented the edgewise appliance — a prototype of modern-day fixed brackets. Dr. Angle had an erroneous idea that all malocclusions can be fixed without premolar extraction and once the teeth are aligned, the jaws would grow naturally into ideal positions. Being confused by Dr. Angle’s beliefs, for the first six years Dr. Tweed practiced without the removal of premolars. Consequently, he found that he was successful only in 20 percent of his patients. The remaining 80 percent of his patients had unstable dental results and unaesthetic facial profiles [1]. This led him to collect a famous sample of 100 patients which he retreated with premolar extraction after initial unsuccessful non-extraction treatment.
From Orthodontia to Orthodontics
Due to a strong influence of Dr. Angle on the orthodontic community, for almost four decades premolar extraction had been considered a taboo in the US. It took time and effort to reintroduce the procedure of taking teeth out back into orthodontic practice.
For the first time Dr. Tweed presented meticulously collected records of 100 retreated patients at the annual American Association of Orthodontists meeting in Los Angeles in 1938. As his contemporaries remembered later, the results were “beyond criticism”[2]. Symbolically, this was the year when orthodontic specialty finally adopted its current name — orthodontics[3]. Before that, an accepted name was ‘orthodontia’, which due to its suffix ‘-ia’ was probably more suitable as a name for some disease. Suffix ‘-ics’, on the contrary, represented belonging to the exact sciences, such as physics, optics, mathematics.
Apart from pure semantics an important factor that put orthodontic specialty on a scientific footing was the development of cephalometrics. It provided orthodontists with some definable treatment objectives. After the invention of a cephalometric machine by Holly Broadbent in the early 1930s, Dr. Tweed was one of the first private practitioners who got the machine in his office. This helped him to collect a substantial radiographic data and develop his famous diagnostic triangle, one of the most fundamental cephalometric analysis.
Why is Charles Tweed still important?
Historically, the opinions of leaders — like in the case of Dr. Angle — were very important in the orthodontic specialty. This many times facilitated the spread of various dogmatic ideas and eventually resulted in erroneous treatments.
I think Charles Tweed’s story teaches us to be always cautious of popular ideas “du jour” and to always take into account currently available evidence while making clinical choices. This may sound banal in the era of evidence-based orthodontics. However, we should remind ourselves that unlike orthodontic evidence which was dramatically expanded over the past decades, human nature underwent little changes and we still have a plethora of flamboyant “opinion leaders” driven by greed, ego, and an irresistible desire to post fancy food on social media.

That’s an interesting study. Let’s discuss. Do you use a FM? With or without TADs? I think I stopped using FMs for the last 5-6 years.

Friday’s clinical Tip 💡
🚫 It is an error to position lower first molars tubes too far gingivally , either to avoid occlusal interference or due to the welding height on the band.
⚠️ Placing the molar tube more gingivally will produce unwanted buccal root torque.
✔️ Correct vertical positioning is needed to avoid unwanted torque changes and poor alignment of marginal ridges.
