Greetings from Synapse HealthTech.
We're delighted to introduce Torque of the Town, our very first newsletter, written to open up conversations across the orthodontic community and, just as importantly, to learn from what you tell us in return.
Every issue begins with a crossword with order discounts for the winners, followed by a real case from our planning desk and how we went ahead with it, instances from the business world worth taking inspiration and ideas from, and finally a conversation with an orthodontist we admire. As an add on, we also have the invite for a national workshop to be held in Bangalore from the 4th to the 6th of September.
And this is a two-way street.
Your feedback decides what we publish next. Reply buttons sit on every page, so use them freely.
Let's begin the newsletter with a simple segment. Six clues from your own vocabulary.

The French astronomer Pierre Janssen set up a spectroscope in a tobacco field in what is now Andhra Pradesh and waited for a total eclipse. In the six minutes of totality he found a bright yellow line in the Sun's atmosphere that matched no element known on Earth.
It was helium.
Still the only element in the periodic table to be discovered somewhere other than this planet. It would be another 27 years before anyone on Earth held any.
Some cases are difficult because a lot is wrong. This one is difficult because two things are wrong in opposite directions, and fixing either one alone makes the other worse.
The upper arch is constricted on the left. The lower arch is wide. Put those together and you get a posterior crossbite that no amount of upper expansion alone will comfortably close. Meanwhile the lower anteriors are severely crowded, 46 is missing, and 47 has tipped forward into the space that crowding needs.
Expansion and constriction of 4–4.5 mm in opposing quadrants is precisely where a conventional tray struggles. Push the upper out and you tend to flare the crowns rather than move the roots. Squeeze the lower in and the tray simply flexes away from the tooth.
With BioSmart shape memory aligners the activation is built into the material rather than into the fit. Thickness is increased palatally in the upper left posterior to drive expansion, buccally in the third quadrant to drive constriction, and anteriorly as well, to add to the crossbite correction. The force then arrives from the side it is needed rather than from the tray gripping the whole arch.
Thickness on its own, though, would still only tip the crowns. So a counter moment is planned against each of these movements, and that is what converts tipping into bodily movement. Worth saying plainly: this is not something particular to shape memory aligners. A counter moment belongs in conventional treatment planning just as much. The material makes it easier to deliver, not necessary to invent.
Because no single movement is large. The crossbite is roughly 8–9 mm of correction, and we have split it in half — 4–4.5 mm from each arch. Halved movements sit comfortably inside what an aligner delivers per stage, which is what keeps the tray in contact with the tooth instead of unseating from it.
Because the space exists before it is needed. Extracting 38 first means the third quadrant constricts into room that is already there. Nothing in the sequence depends on space we are hoping to find later.
Because the force is directional. Thickness-modulated activation puts pressure on the specific surface that needs it, so the movement does not rely on the whole tray gripping and holding.
And because the two arches work against each other by design. The upper expands while the lower constricts, so each arch braces the correction of the other rather than fighting it. That is the argument for this plan: every difficult movement in it has been made an easy one.
The lower carries more than twice the staging as the lower arch has to accommodate the decrowding, the constriction and the extraction-space closure.

Somewhere in your clinic is something so small that nobody has ever thought to question it. That is usually where the money is.
The business world has names for these things, and some genuinely surprising stories attached to them. Each of the three below is far smaller than you would expect, and each turned out to be worth far more than anyone guessed.
In 1987, American Airlines was under pressure to cut costs without upsetting passengers. Its chief, Robert Crandall, went line by line through the catering budget and stopped at the salad served in first class. It came with a few olives. Someone had counted, and most passengers were leaving one behind.
So he removed exactly one olive from every salad. Nobody complained. Nobody noticed. It saved the airline about $40,000 every year.
Van Halen toured with nine trucks of equipment into venues built for three. If a stage was wrongly rigged, people could be badly hurt. Their contract ran to dozens of pages of technical requirements, and nobody read it properly.
So the band buried a strange clause in the middle: a bowl of M&Ms backstage, with all the brown ones removed. It was never about sweets. If the singer walked in and saw a brown one in the bowl, he knew instantly that the contract had not been read, and he ordered a full inspection of the entire stage. He said it almost always turned up a real technical error.
Aravind Eye Hospital in Madurai treats most of its patients free, funded by those who can pay. To make that work, it had to find far more surgery in the same working day, without asking anyone to rush.
So it changed the room. Every theatre has two operating tables instead of one. A surgeon finishes a patient, turns around, and begins the next patient who has already been prepared and anaesthetised by a separate team. The surgeon never waits for a room to be cleaned or a patient to be readied.
The result is not a small improvement. Their surgeons perform well over two thousand operations a year, against an Indian average nearer four hundred.
An olive. A sweet. A second table.
None of these came from a bigger budget or a busier day. They came from someone finally looking closely at something everyone had stopped seeing. Every clinic has its own version of each, sitting in plain sight.

In our very first edition, we're delighted to feature Dr Sarojini Joseph, senior orthodontic consultant with St John's Academy, founder member of the New Faces Trust, and for over two decades a mentor and guide to young orthodontists. She has worked in cleft and craniofacial orthodontics since 1989 and taught postgraduates for fourteen years. Today she devotes herself to training the next generation. In this edition she talks about learning, honesty, and the conversations nobody prepares you for.
“Force is the tool of the orthodontist, just as the axe is the tool of the woodcutter.”
The workshop Dr Sarojini Joseph spoke about on the previous page, run as the Dr Kandavara Sadashiva Shetty Training of Trainers Programme. Three named lectures, delivered by faculty from Yonsei University in South Korea, the University of Siena and the University of Naples Federico II.
