What is Orthodontic 2 by 4 Appliance| 2x4 Orthodontic Braces

   The journey to the perfect smile is directly associated with maintaining the ultimate dental and oral health. When it comes to orthodontic problems, bite issues fall among the most common in both children and adults. This is where a 2 by 4 appliance steps in. Although frequently used in orthodontics, a 2 by 4 appliance failed to get the exact popularity as devices similar to it. However, what makes a 2 by 4 appliance stand out is its multipurpose use, as well as favorable results stemming for its application.

To make things clearer, let’s dig deeper into how a 2 by 4 appliance helps treat various orthodontic issues, including crossbite.

What is a Crossbite?

In dentistry, a crossbite represents a common orthodontic condition which manifests in early childhood. In cases of a crossbite, the top and bottom teeth are improperly placed in the back of the mouth. Typically, the condition shows a significant positioning of the upper and bottom teeth behind one another. In addition, a crossbite is divided in two main types. The first type of crossbite is also known as posterior crossbite. The problem occurs when the top, back teeth find themselves deeper than the bottom teeth. At the same time, an anterior crossbite is a condition in which the top, front teeth lay far behind the bottom teeth.  

Conclusively, a 2 by 4 appliance is a great way to treat both types of crossbite.

In some cases, just as with crossbite, a 2 by 4 appliance can also solve teeth overcrowding issues.

What is a 2 by 4 Appliance?

A 2 by 4 appliance is an orthodontic tool, very similar looking to braces. The appliance itself is fixed and works based on an easy activation. Mostly used in children, a 2 by 4 appliance impacts a wide range of problems, thus also showing lasting effects.

Among the most important aspects in using this device, is knowing the primary teeth won’t be affected by the treatment. Of course, the appliance’s usage and installment requires a bit of force, but no pain whatsoever. Still, in cases of painful experiences, your orthodontist can prescribe milder sedatives to help with the discomfort.

How is a 2 by 4 Appliance attached?

In most cases, a 2 by 4 appliance is placed onto the first molars and on all 4 incisors of the arch. Fitting a 2 by 4 appliance well is crucial in treating crossbite successfully. In the process, some patients are likely to experience a certain extent of root damage, too. However, no tooth loss has been reported as a result of wearing a 2 by 4 appliance.

As soon as the treatment is complete, your orthodontist may also use retainers to further strengthen and fix the teeth. Retainers will also serve the purpose of preventing crossbite reoccurrence.

How does a 2 by 4 Appliance work?

Initially, the fixed device uses four brackets bonded onto the new maxillary permanent incisors. At the same time, two bands of the device are cemented with a wire holding the device together to support the teeth even further. Sometimes, your doctor may also use rubber tubings and coil springs to ensure the brackets and bands proper placement.


Awesome experience with Dr. Ivanov! He shows great passion in his work, and cares about his patients and their concerns. I had my braces for 1yr 11 months and now I’m wearing my retainers. It amazes me as I look at my before and after pics of how great he is. Very happy and well pleased with my results that I referred a colleague of mine. Special thanks to Dr. Ivanov and his team for the fabulous job done!

I took my son to Dr. Ivanov because he had a severe overbite. The doctor explained everything to me with patience and understanding. I noticed the improvements in no time. I thought my son would be in braces for 3-4 years. My son, under Dr Ivanov’s care, now has the straightest most beautiful teeth (in only 2 years)!. The shape of his face adjusted to the changes as well and he looks ‘Hollywood’ Ready’. I am very satisfied with the doctor’s work. His office staff is great as well. Dr. Ivanov is very professional and I highly recommend!

Amazing experience! I’ve had my braces for 6 month now and I’m impressed of how much my teeth have changed. No pain at all. Dr. Ivanov is such a sweet person and very professional, he knows what he’s doing and always cares for patients personal concerns. Highly recommended!

Dr . Ivanov is in one word AMAZING . I been under his care for a year and I got to say What a change!!! I cannot wait to see the final results . . He always answers all my questions, in every visit he will take the time to understand how my teeth are improving and always makes the right decision. The staff is awesome, I always feel right at home . I made the best choice when I decided to get my braces with Dr . Ivanov. There’s is no doubt he is the best ortho . Thank you Dr. Ivanov for the hard work and for being so amazing and helping me feel awesome with every month visit . Anyone who is looking for a good ortho and the best care , there’s no other , Dr. Ivanov is the man!!!

Dr. Ivanov, Amy, and Helen are great! Dr. Ivanov took his time to get to know me, understand my needs, and come up with a treatment plan within my expectations. He offered various treatment options, and Amy and Helen offered payment options. They answered multiple questions without hesitation and with patience. They are all very friendly and personable. Happy I got my braces with them today. P.S. They all worked very quickly to get my braces on as painless as possible. And it went better than expected.

Dr. Ivanov was amazing. When I first got my braces I was scared it was going to last 4yrs for my teeth to look better but it only lasted 2yrs and the results are beyond amazing. I’m really happy with everything and would absolutely recommend him to anyone. Thank you so much.

Dr. Ivanov was my orthodontist. I had a very difficult case, I had an opening in my front area when I closed my mouth. Most orthodontist that I went to said that this case would be impossible to do without surgical intervention. Dr. Pavel thought outside of the box and was able to straighten my teeth WITHOUT surgical intervention. I felt that I was in safe hands because after careful research I found that he graduated at the very top of his class. He was able to do a complex braces technique called the MEAW technique to straighten my teeth. He has restored my self confidence and smile. I highly recommended Dr. Ivanov, he will go out of his way to make sure that your treatment plan is well thought out and he will spend his time to evaluate your situation. He is the Best Orthodontist in the North Miami\Aventura area.

I’ve been visiting Ivanov since December 2015. I had crossbites, crowded teeth, and just all the works. Together with his professional and amazing staff I was able to slowly over the years fix my smile into something life-changing. I am internally grateful to him as well as his staff, especially his assistant and front desk. If you don’t come here then you’re just passing up a great opportunity to change your life for the better and meeting amazing people who will help every step of the way to getting you a better smile! Thanks again, Mr Ivanov.

Very good experience. The attention was great. The doctor is very punctual and they don’t make you wait, which for my busy schedule is super important. Also, the time the doctor told me I had to wear the braces was the exact time I needed and I was very happy with the results. Definitely recommend him.

Dr. Ivanov and his staff really feels like my second family here and they’re always looking out for the best of me. When I first came into the office, my teeth were quite messed up, but now only after a year, it feels surreal that the braces could fix them so well. I see myself smiling alot more and feeling much more confident to show my teeth than to just smirk like I used to. They give you good advice on how to take care of yourself and take the extra step to make sure you do. When I come here for my checkup, I never feel awkward or uncomfortable because they’ll welcome and talk to you as a friend as well as your dentist, something I feel good about when I think about it walking out and saying “See you next month!”

Dr. Ivanov was amazing. He was very understanding and took the time to explain, every step of the process for my daughters braces. I am proud to say with great care her braces were finally removed and the end result is the beautiful smile she now has. Thank you

Usually, when a professional says that the reason they do what they do is to see the end results and how happy it makes their patients, you have to take it with a grain of salt. However, with Dr. Ivanov, he doesn’t even have to tell you why he does what he does for you to know that it’s out of pure kindness and enjoyment in seeing a (perfect) smile in his patients. From the very first moment I met him for a consultation for orthodontic work, I knew I was in good hands. Dr. Ivanov is one of the most humblest, kindest, and caring individuals I’ve ever met in the professional field and I know that I’ll have that perfect smile in no time.

Ivan and his staff made my experience a smooth and convenient process. I am absolutely delighted and satisfied with the progress and how far my teeth has come. Ivan and his staff works effortlessly to ensure that my teeth are perfected beyond my expectations. If I had any other choice I would still choose Ivanov Orthodontic experts.

What are the benefits of wearing a 2 by 4 Appliance?

According to plenty of research-based examination, a 2 by 4 appliance offers plenty of treatment benefits. First off, a 2 by 4 appliance is far more versatile than remaining orthodontic devices. With that, the device targets a greater range of problems and acts on effectively solving them.

What is more, the device is worn no longer than 6 months, which boosts its efficiency even more. Some of the other main benefits a 2 by 4 treatment include:

  •         Reducing overjet, in order to balance the ectopic incisors.
  •         Providing a more effective tooth alignment, through a 3D teeth management.
  •         Rotating the misaligned teeth and correcting diastemas.
  •         Managing incorrect tooth inclination as well as angulations.
  •         Accelerating the postponed eruption of a central incisor, thus enabling a greater freedom in repositioning the teeth.
  •         Increasing the self-esteem.
  •         Offering a quicker, yet equally successful treatment.
  •         Cheaper than remaining orthodontic treatments.
  •         Maintaining the ideal shape of the arch.
  •         Controlling the anterior teeth development.
  •         Enabling an easier application and smoother wearability.
  •         Targeting several issues all at once.
  •         Preventing Class II malocclusions in early childhood.
  •         Minimizing the potential root damage during the treatment.

In addition to all these, a 2 by 4 appliance can also protect the jaw and prevent possible obstructions. The main objective of the appliance is to achieve a better-looking facial profile and fix complications related to the maxilla and mandible jaws. Finally, a 2 by 4 appliance can be used to treat overbite as well.

What are the disadvantages of wearing a 2 by 4 Appliance?

There are a few side-effects which can occur as a result of a 2 by 4 treatment. Obviously, with the installation of the device, the patient may experience a certain discomfort while wearing it. In addition, the appliance does not focus on correcting skeletal issues. Finally, some of the brackets may break or crack. In case this happens, make an orthodontist’s appointment to get the replaced accordingly.

When can I start 2 by 4 Appliance treatment?

According to experts in the field, the sooner you seek a 2 by 4 appliance treatment, the better. In fact, wearing this device from an early childhood enhances your chances of fixing the aforementioned issues. The first thing to do before seeking treatment is keeping an eye of a possible Class II malocclusion. Still, the best thing about this treatment is that the child doesn’t have to wait for its permanent teeth to erupt first.

Once starting treatment, it is important to teach your child how to maintain a constant oral hygiene. By cleaning and brushing the device regularly, the child avoids possible infections and additional gums problems as well. For the best treatment plan, schedule a check-up appointment with your orthodontist, also consulting him on any concern you may have.

Having a nice smile is important to everyone and it is good to know that when yours is less than perfect, it is possible to solve it. Having a cross bite can be problematic, but it can be solved, and your orthodontist is going to have the perfect way to do it. A crossbite is a condition whereby the teeth at the top or bottom end up behind each other. When the back top set of teeth are more inside then the lower set it is called a posterior crossbite and when the front top set is behind the lower set is called an anterior crossbite. Overcrowding can also be a problem, but it will be possible to correct this with the use of a 2 x 4 appliance. There is a great advantage over certain types of treatment when it comes to using this appliance.

The space opening has to be accurate and it is vital that this can be controlled– and when using this appliance, it can be controlled easily. As it is a fixed appliance, there is also a special amount of force that will be used, and this is going to work much more effectively than it would with a removable appliance. A good thing about this form of treatment is that the primary teeth will not be affected. When there is force it is to be expected that the treatment is unfortunately unlikely to be pain free, but it can be controlled with medication. It will also be worth it when both you and the child see the final result.

How Is 2×4 Appliance Fitted?

The teeth that will have the 2 x 4 appliance fitted are the first molars and then the incisors that are in the same arch – this will be the 4 of them. Great care must be taken when fitting them to correct the crossbite. It is possible that teeth can be lost due to incisor roots connecting with the erupting canine’s crown. It is not uncommon to get some root damage. Most of the times, it will not lead to the death of the tooth.

Brackets are bonded on and at this stage the orthodontist will adjust them to be in the right position. This is not only going to be easy process but also should be relatively fast one. It may not look ideal at this stage, but it is a lot better than having to have a tooth removed. The looking good part will happen towards the end of the treatment. A lot of orthodontists will use a retainer once the procedure has been finished. It is not likely that the anterior crossbite will come back. This way the teeth will not be able to move more freely and will allow the orthodontist to monitor the progress. The orthodontist should tell you why your child is getting a retainer.
