Retention of teeth - Varieties | Elimination of anomaly

, medical partner of Star Smile, St. Petersburg

Patient N came to my clinic complaining of a lack of space for the lower canine.

The patient is 21 years old, a sociable, positive, sociable young man.

The patient's main desire was the absence of braces in the oral cavity. The patient wanted the treatment to be as aesthetic and unnoticeable as possible; he said that he was not ready to walk like an “iron man” with iron structures in his mouth.

So, the task is not an easy one - not to turn the patient into Iron Man... Although the hero of the blockbuster of the same name Tony Stark evokes sympathy among many, we are talking about another comparison - the hero Willy Wonka as a child from the wonderful and kind film “Charlie and the Chocolate Factory”:

Before we look at the happy history of bite correction, let's touch a little on the bite problem itself, and what you should always pay attention to. Still, if you see crooked teeth, then it is important to understand some points that can and should be corrected so that there are no more problems with teeth and the temporomandibular joint in your future life.

A little theory:

Dentists, and especially we, orthodontists, very often use the term “Occlusion”, which is incomprehensible to many. Don't be alarmed, everything is very simple. I'll explain now.

Occlusion

- nothing more than the contact of the teeth of the upper and lower jaws.

In the modern world of dentistry, the understanding of occlusion is complex and includes the relationship of teeth, masticatory muscles and temporomandibular joints. And we always look at the bite precisely from the point of view of the function of the bite or its violation - bite dysfunction.

We consider occlusion as any contact between the incisal edges or chewing surfaces of the maxillary and mandibular teeth.

Why are these contacts between teeth so important?

Besides the fact that crooked teeth themselves look ugly and unaesthetic, but seriously, occlusion is very important in order to provide you with competent and optimal treatment. If you look carefully in the mirror at your teeth, at their contact with each other, you will see that the teeth have tubercles at the end, which are called fissure-tubercle contacts. And correct, stable occlusion is ensured by multiple uniform fissure-tubercle contacts of the lateral teeth, which are characterized by the presence of antagonistic cusp slopes on the occlusal surface of the contacts.

Cool and difficult with tuberculate contacts?

We’re done with the theory)) I’ll just note that correct occlusal contacts provide axial load on the teeth (we will see this in the photo of our patient), create stable central occlusion and eliminate overload of the tissues around the tooth - the periodontium.

For us orthodontists, occlusion is the central point of treatment, which should generally be aimed at optimizing the occlusal relationship of the patient's teeth with each other.

Molars are the 6th, 7th and 8th molars. Molars are also called molars, respectively. In the photo above it’s the molars. They perform the most important function in the human body - chewing and grinding food, which is why dentists often call them “chewing”. But the most harmful of the molars are the eights, or “wisdom teeth,” which can greatly harm the patient when they erupt.

So in this case, the “wisdom teeth” of the lower jaw had a fairly strong negative impact on the patient’s lower jaw, practically pushing the canine out of its place in the dentition. So, let's see.

External features of eye teeth

Eye teeth are visually very different from both the front teeth and molars. The eye tooth has only one root. It is relatively long and slightly flattened. The crowns of the eye teeth have two cutting edges located at an acute angle to each other. They also have a slightly flattened shape.

The upper eye teeth are noticeably larger and longer than the lower ones. Their cutting surface is much wider than that of the lower canines.

Nature entrusted these teeth to hold food in the mouth and tear food into pieces.

The patient had the following condition at the time of presentation:

In the case of our patient with a bite of molars “sixes” and “sevens” it is quite positive. The “eights” on the lower jaw were removed - it was their eruption that led to the displacement of the dentition and the appearance of such an unpleasant aesthetic imbalance in the patient’s smile. But everything can be fixed!

Displacement of the lower canines forward from the upper canines on the right and left

3rd class for canines on the right and left

Shift of the midlines due to the lower jaw to the right

Crowded position of teeth in the lower jaw

Lack of space for the lower right canine

And in general - narrowing of the dentition

Let me remind you that the main, basic desire of the patient is to avoid the presence of braces in the oral cavity.

As I wrote earlier, the patient wanted the treatment of crowded teeth to be as aesthetic and unnoticeable as possible, explaining that he was not ready to walk with glands in his mouth and be an “iron man” with iron structures in his mouth. Morally, at his young and active age, it’s hard, you’ll agree. After all, external, visible braces in this case are actually already “last century”, in the sense of technology of the last century, which has already been replaced by new, more advanced and effective technologies of the 21st century.

Based on the wishes of the young man, I proposed two options for treating crowded teeth and straightening canines using the following orthodontic equipment:

• Aligners
  are transparent aligners, which are worn in the process of correcting the bite unnoticed by others. The aligners can be removed when eating and brushing your teeth.

• and lingual braces
  - invisible braces that are attached to the inside of the teeth and are also not visible to others. But they are felt by the patient when worn. and removing lingual braces is not possible until the end of the entire treatment

Eye teeth in teenagers

The permanent lower eye teeth are formed at the age of 9-10 years. The upper fangs appear after 1-2 years.

In a healthy child, the formation of permanent eye teeth is painless. If this process is accompanied by pain, then this indicates a serious problem. This usually happens if diseases of the oral cavity occur, such as gumboil, pulpitis, periodontitis or other inflammatory processes. In such a situation, you should not try to get rid of the problem yourself. The most you can do is take a painkiller and immediately go to the dentist.

As a result, the treatment option using aligners was unconditionally accepted

Why did the patient come to me with the problem of crowded lower teeth?

Still, my orthodontic experience is taking its toll, and recommendations are coming from grateful patients (thank them very much for this!). And in this case, the patient came on the recommendation of his sister, who was my patient several years ago with a very similar clinical situation in the oral cavity (narrowing, crowding of teeth nearby, slight crowding of teeth on the upper and lower jaws).

Did the patient know about the aligners?

Surprisingly, he was not motivated to get aligners. The patient knew about treatment with lingual braces (read on the Internet, saw it with friends), but he had never heard of treatment with aligners. I told him that there is a treatment method using transparent aligners (an alternative to braces), which need to be changed every 2 weeks. Aligners are more comfortable to get used to and wear than braces; oral hygiene does not suffer during treatment with aligners. And what is important, given how busy people are nowadays, is that the patient can visit the doctor less often than with braces. And as a decisive argument, when treating his crowded teeth with aligners, there will be no dietary restrictions.

Preparation for the treatment of crowded teeth is necessary in any case

The patient had already been examined by a therapist, treated all his teeth, cleaned them, understanding that he should have entered the treatment with normal teeth. The young man regularly visits a therapist once every six months (how rare is this to see), but nevertheless, the problem of dental aesthetics due to the incorrect position of the canine in the lower dentition began to grow.

The only additional thing that was done was teeth separation

. Separation is when we slightly carefully increase the interdental spaces by comfortable grinding, in a way that is safe for tooth enamel. During the entire period of treatment, five separations of incisors and premolars on the lower jaw were carried out due to crowding - to make room for the canine.

This is a very important point. And there is no need to be afraid of it, it is natural during the treatment process and absolutely comfortable.

Consequences of premature removal of a baby tooth

These include:

• Bite disorders. Removing a tooth frees up space into which neighboring teeth gradually move. In the future, when a permanent tooth grows in instead of a temporary one, there will be no room left for its normal growth.
• Incorrect formation of the maxillofacial apparatus. Missing one or more teeth can result in insufficient stress being placed on the bone tissue, which in turn can slow down its growth and development.
• Disorders of the digestive system. The absence of one of the masticatory organs leads to poor chewing of food. This can cause a number of chronic diseases.
• Speech disorders. The incisors are part of the vocal apparatus, and the absence of one or more of them will certainly affect the development of speech.
• Psychological problems. The absence of a tooth in the smile area can cause some difficulties in communicating with peers and negatively affect the child’s self-esteem.

Therefore, the popular belief that there is nothing wrong with premature loss of baby teeth is completely wrong. A good dentist always carefully evaluates the feasibility of removing them and, if possible, tries to preserve them. The need for such a procedure must be confirmed by x-ray.

How was dental crowding treated with aligners?

To carry out a full course of treatment, 26 pairs of aligners were made for both jaws; treatment proceeded in parallel on both jaws, including the separation stages.

I immediately gave the patient 4 pairs of aligners; it is very easy to install them yourself - the patient needs to change them for new ones every two weeks.

Then he visited me only 2 months later. One of the previously mentioned interdental separations was carried out to help his canine, which had already begun to fall into place. And again, for a month and a half, the patient forgot about the doctor’s existence. But the doctor does not forget about the patient. This is the beauty of treatment with aligners - it is invisible to the patient)

Temporary fangs - an alternative

If you have any doubts about the need to lengthen your canines for life, pay attention to temporary ones. You can always put them on for a while and take them out if necessary. They are absolutely safe and are attached to teeth absolutely safely. Temporary fangs can be used for Halloween. Ready-made teeth are sold in the store. You can also make the decoration yourself.

It is necessary to take plastic utensils, ground plastic, and place boiling water from the floor. The soft material must be carefully taken with a metal spoon and molded into a fang of the desired shape. Gloves will help avoid burns.

Temporary fangs can also be made from plastic straws, acrylic, or plastic nails. Such fangs do not last long, but they allow you to feel like a vampire and create an excellent image for a holiday or performance.

Let's smile together!

I want to tell you about such an important factor in treatment as emotions. If the attending physician, as a rule, always directs emotions in a positive direction, since correcting the patient’s bite is his profession, then for the patient, every moment of improvement in his current condition, or vice versa, every small anxious moment is a surge of emotions. That's right, because the patient begins a new life with a beautiful smile, and for him in this new life there is already a place for openness and positive impressions.

During treatment with aligners, as agreed, the patient very actively communicated with me using messengers.

Other treatments

What periods would I like to highlight in his emotions:

The first period of treatment for crowded teeth with aligners is “anxiety”

After installing the attachments and giving the patient the first set of aligners, I was faced with his slight anxiety about tooth sensitivity; the patient constantly asked me if it was normal that one or the other tooth was sensitive when biting (to which I replied that this was absolutely normal and this is a period of getting used to the aligners), but after the first week and the patient got used to the aligners, his anxiety also went away. Later, when changing each set of aligners to a new one, he was already calm about the slight sensitivity of his teeth in the first 2 days of wearing the new set.

The second period of treatment for the patient is “satisfaction, sharing impressions”

Subsequently, the patient was so pleased with the chosen treatment method that he constantly told me funny / incidental stories related to removing the aligners in a restaurant or on vacation, or brushing his teeth at work after eating:

• Once
  I wrapped my aligners in a napkin in the cafeteria at work and they were taken away along with the tray and thrown away, the patient panicked, called me and asked what he should do?! I suggested either looking in the trash or ordering a new set, but in the end he, a colleague and a canteen worker found them in a trash container! HOORAY)
• Second story
  . I was on a business trip, went to a restaurant for lunch and didn’t take the container with me, took off the mouth guards before eating, put them on a napkin next to me (for some reason I took off the mouth guards right at the table), a family with children was sitting at the next table and the children began to laugh when they saw how he took off his mouthguards, telling his parents: “Look, the guy is taking off his dentures”:

After all, aligners are generally transparent and invisible

The third period of treatment for crowded teeth is “complete satisfaction”

Complete satisfaction is also supplemented by an assessment of how others perceive him - “how cool he is.” Yes, this is cool, treatment with aligners is invisible, aesthetic, every day it adds inner self-confidence to the patient, liberates the person and reveals his potential for communication with friends. This is really cool!

Fourth period of treatment. There is no more crowding of teeth: “I will be bored without aligners”

At the end of the treatment, the patient already said that he did not know how he would live after the aligners, that he would miss them and whether it was possible to continue wearing them after treatment. Do not take this literally, the patient just had a little anxiety - the fear of losing the result he was very satisfied with!

The patient began to smile and laugh much more often!

But this is important for me, as a treating orthodontist. The patient’s smile is the most important gratitude for my work.

Interesting moments that the patient described about the sensations on the aligners

The patient noted in the messenger that his tooth (fang) was moving and he was afraid to remove the aligner along with the fang! The movement of the canine as a result of removing crowding does occur, and as a result, tooth mobility can actually be felt. But since all dental movements during treatment with aligners are planned in advance, and the patient’s teeth are reliably protected in the aligners, all worries were removed.

As I told you earlier, once on a business trip in a restaurant, when he forgot the container and put the aligners next to him on a napkin, the children at the next table laughed that he had taken off his dentures

In fact, aligners can and should be stored in a special container while brushing your teeth or eating

Problems of treating crowded teeth with aligners

There were no problems at all with wearing the aligners. The only thing is that the activator came off once - this was after six months, but this was quickly eliminated and did not affect the course of treatment.

There was a case when a patient went on vacation and did not take his mouthguard retainer with him - his internal retainer came unstuck and the tooth moved back a little, “rotated” as orthodontists say. Now the problem is over.

How to ease the baby's suffering?

It is impossible to ensure completely painless eruption of eye teeth. However, you can help your baby in several ways.

A light massage of the gums slightly dulls the pain. In any case, this stops the kids from crying. To do this, you need to gently stroke the gum just above the eye tooth for a couple of minutes. This massage can be done two to three times a day.

Now pharmacies sell special teethers. Before using, keep them in the refrigerator for a while. These simple products are filled with distilled water. If the baby bites through the shell, then nothing bad will happen.

You can dull the pain with the help of anesthetic gels Dentinox, Kalgel or Kamistad. They begin to act a few minutes after application to the gums.

If the baby’s nose is stuffy during the teething of the eye teeth, then in this case it is worth using drops of Otrivin, Nazivin or Quix. They tend to constrict blood vessels. It also happens that the body temperature of babies rises to 38 degrees or higher. In this case, you have to resort to antipyretic children's drugs paracetamol or ibuprofen. They are available in the form of syrups or candles.

If the baby is having too much trouble with the teething of the eye teeth, then in such a situation it is better to call a pediatrician at home.

My comment on this treatment:

I am satisfied with the result of the treatment and, probably, with the entire treatment process (even the slight anxiety and scrupulousness of the patient), it is nice to see in the end a satisfied, grateful and constantly laughing patient.

A child's teeth grow in two rows

With proper development of the jaw at the right age, permanent teeth begin to erupt and put pressure on the roots of the milk units.
Under this influence, the roots dissolve - the baby tooth becomes mobile, it wobbles and then falls out. This is a normal change in bite, the algorithm of which is known to most. But in rare cases the situation develops differently:

1. when the germ of a permanent tooth and the root of the milk tooth are located in parallel planes, there is no pressure on the roots, and the permanent tooth grows in close proximity to the milk tooth;
2. when the permanent one erupts quickly, and the roots of the milk unit have not yet resolved, the tooth does not fall out, and the permanent one has to bend and grow at an angle;
3. when a child has a supernumerary set of teeth.

Various reasons - one result: the child’s teeth grow in the second row, threatening to ruin the permanent bite.

Now let’s imagine what would happen if the treatment of crowding began with lingual braces:

Yes, if the patient had rejected the aligners as a way to correct the bite, then, apparently, the choice would have fallen on lingual braces (considering that initially the patient did not want visible methods of correction)

When choosing lingual appliances as a treatment, I assume that the treatment would be more difficult for the patient.

Considering his increased anxiety and scrupulousness:

• he would not be able to get used to the violation of diction when wearing lingual braces (a lisp, which would definitely be present), and for him this would be a very important aspect associated with constant communication at work,
• he would not be satisfied with his oral hygiene, pain and discomfort when getting used to the braces system (more pronounced than the sensations with aligners),
• he would not be happy with the constant discomfort for his tongue.

Therefore, both the patient and I are very pleased with the aligners - our choice of treatment method and are satisfied with the results obtained!

Preparation

Extension of fangs requires preliminary preparation. Preparatory procedures are divided into preliminary (optional) and immediate (mandatory).

Preparation may include the following procedures:

1. Professional cleaning of tartar, plaque and dirt. The procedure allows you to set the actual shade of enamel for choosing a material. The specialist must take into account the different colors of the base and edges of the tooth.
2. Treatment of caries is a mandatory procedure.
3. Taking impressions allows you to determine the best tooth shape.
4. Canine preparation is carried out before applying the composite material. The procedure ensures tight fixation of the composite on the tissue. The part being built up will receive additional thickness.
5. Grinding of hard tissues - allows you to give the tooth a natural shape. Care is taken during the procedure to avoid damage to the internal layers and eliminate pigmented areas of dentin.

Do you really need lingual braces to treat crowded teeth as your doctor advises?

Are you ready to carry this pile of iron in the form of braces - even cool lingual ones - in your mouth for the entire duration of treatment (a year or two)?
Rub your tongue against them, polish them until they shine, eliminating pieces of food? You will definitely be rubbing not covertly, but clearly, unpleasantly and constantly. Braces are uncomfortable and not aesthetically pleasing. You can have a high-quality consultation with our orthodontists and understand - what if your case of crowded teeth can be perfectly cured with aligners? If aligners can do it, then why subject yourself to self-torture with braces? So, we offer consultation on crowded teeth. Useful for you. The Star Smile company operates in more than 70 cities of Russia and will be able to offer you competent consultation with an orthodontist in your city.

Take the first step towards comfortable treatment.

What should you consider when removing a baby tooth?

The following are taken into account:

• Anatomical features. The walls of primary teeth are relatively thin, and the roots can go deep at a large angle. Therefore, their removal requires the use of special forceps, which help eliminate the possibility of damage to the tooth walls. Pulling out is done in one motion so that the baby experiences minimal discomfort.
• Pain relief. In most cases, anesthesia is not required, especially if the tooth is already loose. Local anesthesia may be required to remove the nerve. The required dose of the drug is calculated individually for each patient.
• Contraindications to the procedure are diseases that cause bleeding disorders (leukemia, hemophilia), hematomas in the mouth, chicken pox, whooping cough, scarlet fever, influenza, sore throat, etc. Gingivitis and candidiasis can also be a reason to temporarily postpone the procedure.
