Lower distalisation with miniscrews in Class III
Many Class III cases come with maxillary hypoplasia, and that hypoplasia is rarely only transverse: it almost always has a sagittal component too. So in these cases the order of movements matters as much as the movements themselves. First we sort the maxilla, and only then do we distalise the lower arch, leaning on skeletal […]

Molar intrusion with miniscrews to close an open bite
With an open bite there comes a point where you may have tried every sequence going, posterior intrusion, anterior extrusion, bite ramps, and still not closed it. When the aligner on its own cannot deliver the posterior intrusion the case needs, the answer is not to push harder with more of the same, but to […]

Moving teeth with gingival recession: sequence before force
In a tooth with marked gingival recession, the risk isn’t so much in the movement you want to make as in when you decide to make it. Moving it early, before you have anchorage, is the quickest way to lose control exactly where the tissue is most delicate. The key, almost always, is the sequence. […]

Attachments in clear aligners: what they do and which types matter
Clear aligners move teeth with light, continuous forces, but some movements are hard for a smooth plastic tray to achieve on its own. That is where attachments come in: small tooth-coloured composite bumps bonded to the tooth that give the aligner a defined point to push or pull against. Without them, certain movements are slow […]

Using a Bolton discrepancy to simplify extraction cases
In extraction cases, the hard part usually isn’t opening the space, it’s closing it well. And the movement that complicates most is mesialising the posterior segments to bring the canines into Class I. Before committing to that movement, it’s worth reading a figure that often rewrites the whole mechanics: the Bolton discrepancy. The Bolton discrepancy, […]

Clear aligner training for orthodontists: what actually moves the needle
Most of us learned aligners the hard way: a weekend intro, a stack of tutorials, and then a lot of trial and error on real patients. It works, eventually, but it is slow and it costs refinements. The gap is rarely the software or the brand. It is the biomechanics, and biomechanics is exactly what […]

Third molar anchorage for arch development, step by step
In severe crowding, the first decision isn’t how to align, it’s where the space is going to come from. Most of the time we move between two options that both carry a cost: expanding, which loses arch depth, or compressing, which proclines the incisors beyond their biological limits. There’s a third route that many cases […]

Closing diastemas with aligners without losing incisor torque
Closing diastemas with aligners has a trap that shows up almost every time at the same point: once the incisors start retracting, the torque gets lost. The result is a retrusion that closes the space but leaves the incisors tipped palatally, with everything that means for aesthetics and long-term stability. Avoiding it doesn’t take extraordinary […]

Closing extraction spaces with reciprocal anchorage, step by step
Closing extraction spaces with aligners is one of the scenarios where improvisation shows the most, and where the lack of a clear protocol shows even more. In Class II or Class III cases requiring full correction, where a direct staging would be complex, the key is sequencing the movement with reciprocal-anchorage logic that lets you […]

The sandwich technique: solving severe crowding without stripping, extractions or TADs
When a severe crowding case comes in, the first options that come to mind are almost always the same: stripping, extractions or TADs. In some patients, whether for periodontal reasons, patient preference, or both, none of those is viable or desirable. The sandwich technique is the alternative when the crowding has to be resolved without […]

Second molar in crossbite: solving it with aligners, without elastics or TADs
A second molar in crossbite is often filed under “needs elastics or miniscrews.” In many situations that assumption is reasonable, but it is not inevitable. With a sequence designed properly, and with the patient’s own occlusion used as a biomechanical resource, this case can be solved without auxiliaries. What follows is how, and above all […]

Molar flaring after expansion: turn it into a resource
After a palatal expansion, buccal tipping of the molars is almost inevitable. It does not matter which device you used: when you gain several millimetres of transverse width by pushing on the molars, those teeth end up with negative torque that has to be corrected. The question is not whether it happens, but what you […]
