Preparing the teeth for wearing clear aligners
Before handing over the invisible aligners, the orthodontic specialist reviews the treatment plan and checks which procedures need to be performed on the teeth during the first appointment. Below, I will list the most important tasks of this type.
1. Attachmentek felhelyezése
One of the most important elements needed for every Invisalign treatment is the placement of the so-called attachments on the teeth. Attachments are small, aesthetic (tooth-colored) composite resin bumps bonded onto the teeth. They play a key role in moving the teeth in the correct direction and in anchoring the aligners. Without them, aligner-based orthodontics would not be possible. To place the attachments, we must first clean and prepare the teeth. Then, using a template, we place the little composite domes in the proper locations, where they harden under blue light. It is important to note that the tooth enamel is not harmed during the procedure, nor when the attachments are removed.
2. Interproximal enamel reduction (IPR)
Before we dive into this topic, let me mention that during the discussion of the digital treatment plan, you may decide that you do not wish to undergo this procedure. In that case, the dentist will explain to you the alternatives and possible disadvantages of not doing IPR and will modify the treatment plan if you still don’t wish him to do it. Now let’s look at what exactly IPR is. In certain cases, there is not enough space available within the dental arch. The reason is usually severe crowding, but discrepancies in the size of the upper and lower teeth can also cause this situation. In this case, we somehow must create some space, and enamel reduction provides a solution to this problem. Before I explain in more detail how this process works, I would like to dispel all doubts. It is very important to know that the procedure is completely painless, and no anesthesia is needed. The teeth are not damaged, and they will not develop cavities later as a consequence of IPR. The maximum amount of enamel removed is half (0.5) a millimeter, which corresponds to the thickness of human hair. (The extent of reduction is precisely defined in the treatment plan, and the dentist always follows this guideline.) The procedure is usually performed using polishing strips or a very thin, fine-grained bur. Yes, I know and understand your concerns regarding this procedure. However, please allow me to advocate a bit for enamel reduction. It is a completely proven and very frequently used procedure in orthodontics, not only for aligner-based, but also during traditional fixed orthodontic treatment. It has numerous positive effects and no negative consequences. With its help, we can shorten the treatment time, avoid tooth extraction, protect the periodontal tissues, decrease the chances of root resorption, and solve problems that might otherwise prove impossible.
3. Placement of aesthetic little buttons for rubber bands
In certain bite irregularities (crossbite, mispositioned jaw) and for anchorage enhancement, it may happen that the patient must wear small elastics during certain phases of treatment together with the Invisalign aligners. These elastics can be hooked onto the small buttons bonded to the teeth. They are completely unnoticeable (tooth-colored) and comfortable (their surfaces are smooth), so wearing them poses no problem.
4. Handing over the aligners and demonstrating their use
Once we have completed the tasks described above, nothing remains but to hand over the beautiful new aligners. First, the doctor tries them on the teeth and checks whether the aligners fit properly. If everything is in order, the dentist then asks the patient to remove the aligners and then insert them again. Throughout the process, there will be help in case you get stuck at any point. There is no need to worry, because removing and inserting the aligners is simple. Even younger children manage this task with ease.
