Common manifestations of misaligned teeth Let’s take a look at several common malocclusion manifestations.
1. Crossbite: Commonly known as the overbite, when a normal person bites his teeth, the upper teeth bite on the outside of the lower teeth, that is, the upper and lower teeth have an overbite covering relationship. If the lower teeth are located on the outside of the upper teeth in reverse, it is like the earth wrapping the sky in reverse, which does not conform to the laws of natural existence. We call this relationship between the upper and lower teeth a crossbite. Crossbite has serious effects on chewing, pronunciation, and developmental coordination of the upper and lower jaws.
Excessive growth of the mandible, far beyond the normal growth of other tissues, broke the developmental balance of the maxillofacial region, and undoubtedly seriously affected the appearance of the face; , like a bud of a crescent moon.
Most patients with this crescent-shaped face have a sad face. In addition to aesthetics, the poor alignment of the teeth affects chewing, affects lip closure, affects pronunciation, and in severe cases can lead to physical and psychological developmental disorders. Patients with crossbite should see a doctor as soon as possible, and accept the guidance and treatment of an orthodontist. As long as the child has just learned how to cooperate, he can go to the doctor.
At different ages, orthodontists have different methods and means. However, the crossbite may be repeated repeatedly, the deciduous teeth are cured, and the mixed teeth appear again; the mixed teeth are cured, and the permanent teeth may recur again. Patients, family members and orthodontists need to work closely together, and sometimes need the help of maxillofacial surgeons, to achieve the most perfect treatment results.
Crossbite is prone to recurrence, which is related to its etiology. As we said before, orthodontics only has good effect on dental deformities, but relatively poor effect on skeletal deformities. In crossbite, skeletal deformities are more common, but children are not at the peak of growth and development, and it is difficult to judge his skeletal tendencies. A small number of patients with crossbite are mainly due to dental factors, such as inappropriate bottle feeding methods and bad habits of biting the lower lip. At this time, if there is no active treatment, the development of bones may be induced by mistake, and the dental and functional deformities may be fixed and developed into skeletal deformities.
2. Too much teeth: maxillary protrusion, mandibular retraction and bimaxillary protrusion. Some people require correction because the upper teeth are protruding, the lips cannot be closed, the front teeth are everted, and the side profile is too convex. Doctors have carefully inspected the teeth of these patients, and often found that the entire lower jaw is receding, the upper front teeth cover a lot of the lower front teeth, the lower front teeth often bite deeply, and the back teeth are in a cusp to cusp relationship. . Most of the patients come here for aesthetics. In fact, this kind of mistake has other hazards. Poor occlusal reduces chewing performance; open lips and exposed teeth will promote inflammation and hyperplasia of the labial gums; lower teeth will impinge on the upper teeth with excessive lip tilt when opening and closing the mouth; in order to overcome the obstacles of the upper teeth when opening and closing the mouth, joints, The deformation of ligaments and muscles increases, which can induce temporomandibular joint lesions for a long time. This uncoordinated relationship between the jaws should be corrected as soon as possible. During the period of rapid bone development, functional correctors should be used to make the mandible grow or shift forward.
The use of fixed aligners in the later stage can also solve problems such as crowding of the dentition. When patients seek medical treatment, they often think relatively simple. They often ask doctors to pull back the protruding front teeth. Sometimes doctors ask patients to prepare for tooth extraction. Because the protruding teeth are to be pulled back, there is a need for a movable space in the posterior segment of the dental arch, that is, a gap is required.
In crowded dentitions, individual teeth are often extracted to provide this space. After tooth extraction, the upper front teeth are gradually retracted and erected, the upper lip is retracted, and the lower jaw is drawn out, the patient’s appearance can be greatly improved. Sometimes the patient complains of a protruding mouth, but the front teeth are not bited deeply, and the coverage is not large, and the back teeth even bite well. This is caused by the protrusion of the upper and lower front teeth to the front. This deformity is called bimaxillary protrusion. . To solve bimaxillary protrusion, it is generally necessary to extract individual teeth to provide space to solve the problem of adducting anterior teeth.
It seems that orthodontics often have to extract teeth. In fact, orthodontists are very cautious in designing tooth extraction. Especially for adults, if the teeth suddenly appear uneven in one or two years, a comprehensive periodontal examination is required. If it is caused by periodontitis, tooth extraction is generally contraindicated. Tooth, convex, generally related to genetics, race, etc. Western whites are straight-faced, blacks are convex, and yellows are in between, so whites have less tolerance for protrusion, while blacks can still be accepted by the public with relatively large protrusions.
Caucasians have a straight face. In recent years, orthodontists have been more cautious when extracting teeth to solve the misalignment of their teeth. They are worried about the profile of their mouths. Yellow people can have two choices, either to extract teeth to become straight faces, or not to extract teeth. , to make the face slightly more prominent. South Asian beauty pageant stars tend to have mild bimaxillary protrusions, which also reflects differences in aesthetics between regions. How much will it bring some joy to some patients with mild protrusion?
3. The crowded teeth like tiger teeth and tiger teeth are actually a metaphor for the outward movement of the maxillary canines and lips. Some famous movie stars have slightly tiger teeth, which sometimes makes people feel lively and playful, which adds to their charm on the silver screen, but if a long fang is a little bit more A very beautiful girl, with obvious tiger teeth, seems to be a little soft. Therefore, most teenagers are still willing to straighten their teeth and have a set of perfectly aligned teeth. Sometimes the dental arch does not show a smooth arc, not because of the tiger teeth, but because the other teeth are in and out, and the bite is disorganized. This is actually a malocclusion of the same nature as tiger teeth, which is called crowded dentition. Tiger teeth are just a typical specific manifestation in the category of crowded dentition. Some children complain that their parents have inherited such uneven teeth; some parents wonder why their teeth are so cluttered when they arrive.
In fact, it contains that no one can defy the laws of nature – the evolution of human beings. The official name of tiger teeth is called fangs. Humans have four fangs, one on the top, one on the bottom, one on the left and one on the right. They are almost the last permanent teeth to be replaced. Therefore, when they erupt, the problem of lack of their position in the dental arch is the most difficult. Seriously, in most cases they are pushed out of the dental arch.
In this way, it is not difficult for us to understand why so many people have tiger teeth, which is why tiger teeth are often regarded as a typical example of crowded teeth. Human beings are very smart, things that cannot be avoided innate, we can change as much as possible in the day after tomorrow. Crowded teeth such as tiger teeth can be treated and belong to the dental deformities we have introduced. For patients with permanent teeth, if the degree of crowding is light, movable aligners or fixed aligners can be used to develop the dental arch, that is, the formation of the small arc is expanded into a large arc, so that the teeth that are slightly squeezed out of the team can be arranged. Get in or put the crooked line in order.
If the degree is severe, such as some teeth are almost completely squeezed out of the queue, tooth extraction is often required. Which tooth is to be extracted, we will introduce in detail later, because the canine has a more important position in the oral cavity, it generally needs to be retained. The timing of orthodontic treatment for tiger teeth is relatively late. For simple crowding without the deviation in the three-dimensional directions of the length, width, and height of the jawbone, it is usually necessary to wait until the age of thirteen or fourteen, when all the deciduous teeth are replaced by permanent teeth. If the crowding of the teeth is serious and manifested very early, the orthodontist may recommend a series of tooth extractions when it is confirmed that there are no other problems with reference to the X-ray. Of course, serial extractions should be performed under the guidance of an experienced doctor. If you do not have the conditions to perform sequential tooth extraction, you may wish to wait until the tooth replacement is completely completed before performing orthodontic treatment.
Some people may ask, since the incidence of dentition crowding is so high, after a few years, will people gradually become accustomed to the irregular dentition, and even take tiger teeth as beauty and ask orthodontists to correct a pair of tiger teeth? But aesthetically speaking, neatness and harmony is an eternal theme. Besides, crowded teeth are unhealthy. More and more people are asking their orthodontist to correct their misaligned teeth in the hope of having healthy, straight and beautiful teeth.
