📝 Adult skeletal Class III patient treated with MSE + aligners in 12 months. How?

🔑 As always: good DIAGNOSIS and a clear treatment plan.

🗣️Aligners move teeth, not bone. Severe dentoalveolar expansion can lead to periodontal problems, occlusal instability and relapse.

⚠️In this adult patient, we followed a protocol combining MSE + aligners. In the before and after CBCT, we can see how we maintained, and even improved, posterior torque while achieving a real skeletal gain, aiming for long term occlusal stability and avoiding posterior open bites.

But remember: not every adult patient is a candidate for this type of expansion 🫵 It is essential to understand the suture stage, appliance design, how to make expansion more predictable and, most importantly, when to expand and when not to!

📣 Stay tuned! Next week we will launch our new intensive aligner courses at 🔗Bio Global Clear Aligner Education & focusonaligners.com. Spending 6 months together gives us time to go through simple, moderate and complex cases, giving you a broad range of clinical scenarios and, most importantly, helping you develop your own clinical judgement.

✨ In a world where social media can make the most complex technique look like the best one, simple and efficient solutions are still my favourites✨
💡 CLINICAL PEARL!
Ectopic eruption of the upper first permanent molar is a common developmental issue in young patients. The 6 erupts at an abnormal mesial angle and becomes locked beneath the second primary molar, the “E”, often causing root resorption and early loss of the E.
If the E is lost too early, the 6 can drift mesially, taking up valuable arch space that will later be needed for the second premolar ⚠️
My go to approach is very simple: a separator placed between the E and the 6, changed once a month. This helps redirect the eruption of the molar, protects the E and preserves arch space.
I use this technique particularly often in patients who also require maxillary expansion and present with the 6 erupting in this position, before bonding the Hyrax expander.
Simple, predictable and highly effective 💡 Sometimes, the smallest intervention makes the biggest difference.

Skeletal expansion is easily achievable even in late teens when the right expander design and accurate diagnosis are used! 🦷✨

In this case, a 19yo female, we chose a McNamara expander to increase anchorage and reduce posterior crown tipping. 💪 We also added some overcorrection to prevent transversal relapse once the expander is removed (around 6 months). ⏳

🔍 Complex case of lower incisor intrusion with aligners and TADs. The absence of first and second molars (5s and 6s) limited posterior anchorage, and with no incisor crowding, achieving relative intrusion movements was challenging.

The solution: two interradicular TADs!

💪 Thanks to this combination of biomechanics with aligners and TADs, we achieved controlled, efficient pure intrusion.

Invisible aligners work by applying controlled, specific forces to the teeth, allowing them to gradually move into the desired position. Each aligner is designed to exert light, continuous pressure on the teeth, gradually moving them in the necessary direction. These aligners are replaced periodically, typically every one to two weeks, with each new set designed to continue the dental movement, always progressing towards bite correction and alignment.

Treatment planning is carried out using advanced digital technology, such as 3D scans, which provides precise visualization of the teeth and the movement design to follow. The orthodontist can plan the treatment accurately, ensuring that each aligner fits the patient’s specific needs. This personalization makes tooth movement more precise and predictable, optimizing treatment results.

An important advantage of invisible aligners is that they distribute forces evenly across the teeth, helping to reduce discomfort compared to traditional braces. Additionally, aligners are made from a soft, flexible material that comfortably adapts to the mouth, minimizing irritation to the gums and oral tissues. They also allow for specific tooth movements, such as intrusion (moving teeth inward into the gums), extrusion (moving teeth outward), rotation, or translation (shifting teeth along the dental arch).

Class II intermaxillary elastics can be placed in different ways, depending on the patient's needs and the treatment goals. Here are the two configurations mentioned:

1. From the upper canine to the lower molar: This is one of the most common ways to use Class II elastics. The elastic is placed from the upper canine (on the upper arch) to the lower molar (on the lower arch). This type of elastic helps correct overbite and improve the relationship between the dental arches by moving the lower jaw backward and aligning both the anterior and posterior teeth.

2. From the distal of the upper lateral to the lower molar: In this case, the elastic is placed from the distal of the upper lateral (usually the second premolar or first molar) to the lower molar. This approach is used when greater control over the posterior movements of the upper arch is needed, providing additional anchorage. It helps correct a Class II molar discrepancy without compromising the alignment of the anterior teeth.

Both configurations can be effective depending on the case, but the choice between one or the other depends on the diagnosis and the specific treatment needs of the patient. Generally, elastics from the canine are more common for correcting a Class II, while elastics from the lateral or premolar can be useful for more precise control of posterior tooth movements.

In this 3D video, we can see each stage of dental movement leading to perfect alignment of the lower arch.

Thanks to detailed scanning and the use of aligners, we could precisely plan each step from the initial diagnosis.

Technology and thorough analysis make all the difference in achieving optimal results.
