When planning Class III treatment with aligners, the movements that appear in the software can be confusing. No platform is going to tell us the limits of distalisation, nor how the planned movements will actually occur... And neither can it reflect the effects that the elastics will have on both arches. The reality ...

Jaw expansion is a relatively common treatment for growing patients. Many children have a narrow jaw for various reasons, whether due to habits, a respiratory problem, genetics or inadequate function. This jaw deficiency can be treated with a variety of appliances: Hawley plates, disjunctors, jaw tracks, ...

Talking about what aligners are made of is probably a somewhat "cumbersome" and unattractive subject. We all like to see cases, especially if they are complex, and enjoy the magnificent mechanics that some professionals apply to solve them. But materials and orthodontics are condemned to understand each other. As far as ...

Sequential distalisation of the lower arch with aligners is a relatively predictable and effective treatment for resolving sagittal discrepancy. Before opting for this solution to treat the Class III patient, we must determine the limits that exist for this movement. The limits of distalisation do not depend on ...

The curve of Spee is the natural curvature of the occlusal plane that follows the anatomical shape of the mandibular arch. An excessively increased curve of Spee can lead to various problems such as excessive wear of the anterior teeth, periodontal problems or joint disorders. This last aspect is frequently found in cases where the curve of Spee is too large.
How should we level the curve of Spee with aligners? Read More »
Attachments are a key part of treatment with aligners, necessary to improve the efficiency and predictability of certain dental movements. Even so, they are not essential in all situations. There are movements, such as retroinclination or incisor rotation, that do not require the placement of these attachments to be completed. The ...
We are all attracted to the concepts of "predictability" or "reliability". We want to offer maximum guarantees to our patients in everything we do (and, incidentally, to sleep soundly), but, fortunately or unfortunately, biology is not as exact a science as mathematics. As we have discussed on other occasions, the development of ...
One of the main questions that patients ask us when they come to see us is: doctor, how long is my orthodontic treatment going to take? Some companies, aware of this, use this claim to attract or attract those who are looking for quick treatments regardless of the complexity of their case or to offer those of us who are looking for ...

Digital orthodontics has led to the introduction of 3D printers in the dental sector. These printers can be used for different purposes: printing models with which to manufacture aligners on them, printing retainers or even, as we have recently seen at a congress, printing the aligners directly. In order to guarantee the fit of the aligners ...

Orthodontic treatments, whether aligners or braces, have their limits and may not be suitable for all cases. For this reason, some of our patients will need to undergo orthognathic surgery combined with orthodontics in order to solve their problem adequately. In those malocclusions where the patient presents a skeletal problem ...
Are there any benefits of using aligners in surgical cases? Read More »
Before the advent of aligners, Class II correction by upper distalisation was a difficult strategy to apply. Most cases involved Class II elastics that correct the sagittal problem at the expense of mesialising the lower arch teeth. Due to their greater complexity, in ...
I remember when I was immersed in the world of aligners. In those first trainings, we were shown the strengths and weaknesses of invisible orthodontics. For example, a case with an open bite could be easier to solve with aligners than with brackets, thanks to the intrusion that occurs due to the brackets' ...
Extraction cases with aligners are considered some of the most complex cases to treat with aligners due to the properties of the plastic. When we treat an extraction case with brackets, we have the possibility to choose the stiffness and thickness of the archwire to achieve greater control of the mass movement of the teeth ...
Who hasn't had to scan a patient for a misalignment of a rotated canine? Rotation of round/conical teeth is a movement that can be complex to perform with aligners. The poorly retentive anatomy of the teeth means that the application of forces by the aligners is not as effective as it could ...
Class II malocclusion is one of the most common malocclusions among orthodontic patients. Within Class II, we have two subtypes, division 1 and division 2. Each one of them has a series of dental and facial characteristics associated with it that must be taken into account when designing our orthodontic plan.
One of the great debates in orthodontics that has existed practically since its emergence is whether or not extractions are necessary. If we look back, it is interesting to see how this issue has fluctuated over time, creating orthodontic trends or "currents" that defend the need for extractions or, on the contrary, the necessity of extractions, or, on the contrary, the ...

Can we conceive today's society without the existence of plastic? We live in the age of plastic. As I write this article, on the train, I look around me and all I see are objects made of plastic: the seats and walls of the train, my mobile phone case (lie, those who know me know I don't have one), the ...

We all remember our postgraduate years when we had to measure the size of each tooth on plaster models with a caliper in order to calculate the Bolton discrepancy. A tedious job like no other, in which we spent hours and hours. Fortunately, technology has made this job much easier. ...

When we try to correct the torque or inclination of the incisors, it is common to see how what was planned in the programme does not coincide with the clinical reality. How many of us have seen how the aligners were misaligned when trying to correct the negative torque of the anterior teeth? With power ridges, with vestibular attachments, with palatal attachments... Different ...

Open bites are traditionally one of the most feared malocclusions by orthodontists. The difficulty in controlling the vertical plane, coupled with the risk of relapse that these patients present, makes the treatment of this malocclusion a real challenge. Many patients with an open bite have a number of features or problems with their bite, such as ...
