What Does the Graph Above Mean?
How mechanics determine speed of treatment
The graph above shows the movement speed of our device compared to aligners. Teeth move at very small increments that are hard to see on the screen, so these lines are a blown up version of the speed of movement at a scale of 133x. We want to reiterate, these are actual rates of tooth movement.
Comparing movement speed is always difficult because it is not an exact science. This is also why marketing for different devices is so difficult to understand nowadays. Seemingly every device is faster than the other, and others use other studies to try to substantiate their own methodology of testing for speed.
For us, we want to be as upfront and as objectively honest as we can possibly be. We are very proud of what we are offering, but more importantly, we want our patients to understand orthodontics on a more technical level. This way, orthodontic healthcare for everyone not only increases, but it also further substantiates our technology.
As to the graphs above, our measure of speed is objectively measured by mechanics. The graph states that in two weeks "aligners move 0.3mm max." What we mean by this, is that aligners are made from a clear plastic material that has a known range of material deflection before it permanently deforms of 0.2-.0.3 mm, depending on the company and their proprietary acrylic materials. What this means is the teeth can only move as far as that material can deflect and force the teeth back to the original, un-deformed or passive position of the tray. This distance was readily available by asking the various sales teams who were happy to answer.
Our movement mechanics shave months off of treatment time
For The Skarin System, we are not limited by the flex of a clear aligner material. We are able to determine through accurate, superimposed photographs what distances the teeth move over a known period of time. Knowing the distance moved over time will determine rate, and is conservatively compared to the known rate of aligners to compare treatment times.As previously stated, the Skarin System can move teeth up to 5 times that of aligners.
*AN IMPORTANT POINT* - even if the rate of movement was exactly the same, the significantly lighter continuous forces placed on the teeth in the Skarin System are far safer, more easily tolerated than any aligner system can hope to duplicate. This is how we can state a measurement of 1.5mm max and ultimately make the claim that our movement speed is up to 5x faster than aligners.
Even for cases that require small adjustments for alignment, this principle would still hold true. The Skarin System accomplishes this task up to five times faster than aligners. Moreover, treatment will be accomplished with a gentle force on the teeth that our patients say they can barely feel. Patients often describe the force as "pressure" but without any soreness or pain.
