In fact, the need for orthodontic tooth has already existed for a long time. According to the American Orthodontic Association, archaeologists have found that the mummy’s teeth are wrapped in rough metal sheets. Experts speculate that the catgut in the gap is the modern orthodontic arch.
It seems that we moderns and our ancestors thousands of years ago still have a tacit understanding of aesthetics, that is, the love for neat and healthy teeth.
First, the history of the development of dental appliances
Modern techniques for orthodontic teeth have been developed for over 100 years. Its originator is the world’s first professional orthodontist, anger. Anger announced in 1892 that orthodontic technology was separated from other dental treatments and became an independent discipline. The Angle classification of malocclusion he proposed in 1890 is still widely used in countries around the world.
Ange first proposed the correction techniques of E-bow, screw-tube arch and band-shaped arch. Later, he designed the square wire bow appliance. And he founded the world’s first orthodontic school, and also trained two famous doctors, Tweed and Begg. Among them, the square wire arch correction technique pioneered by Dr. Tweed is still widely used.
2. Teeth orthodontic, FAQs
I heard that you need to extract teeth for correction?
This is an important reason why many people are discouraged from correction.
Tooth extraction is a common but not the only means of providing space. In addition to tooth extraction, clinically, there are many methods such as extending the dental arch in an anterior-posterior or left-right direction, slice cutting (moderately narrowing the teeth), etc., to effectively solve the problems of crowded dentition, protruding teeth, and create space for the teeth. The specific method is selected according to each individual’s dental condition.
Don’t want to pull a tooth?
In fact, 100 years ago, orthodontic treatment without extraction was popular in the dental industry.
However, after treating numerous patients, Dr. Tweed found that reluctantly aligning the crowded teeth, on the one hand, makes the mouth less prominent and unsightly, and on the other hand, the teeth are easily crowded and disordered again after the appliance is removed, that is, recurrence.
So Tweed recalled patients who should have had their teeth extracted in the past but didn’t, and started trying extractions. To this day, tooth extraction is still the main method to solve crowded and protruding teeth during orthodontic treatment.
As for whether to extract the tooth, it is still up to the doctor. The current consensus in the medical community is that whether a tooth needs to be extracted and how many teeth need to be extracted is determined by each individual through actual measurement and image measurement, and is definitely not something that can be determined by one or two promises not to extract teeth.
I heard that the teeth will become loose after orthodontic?
Move ≠ loose
During the orthodontic process, teeth are moving, which is completely different from loosening.
Periodontal disease is the real killer of loose teeth, and dental plaque is the pathogenic factor of periodontal disease. In short, no matter whether you wear braces or not, if you don’t pay attention to oral hygiene, it is inevitable that your teeth will loosen over time.
What’s with the loose teeth?
When the orthodontic tooth moves in the alveolar socket, it will not cause pathological damage to the tooth itself and its supporting tissues, but approximate physiological tooth movement. The ability of teeth to move in the mouth is mainly due to the properties of alveolar bone reconstruction. Human bone tissue has great plasticity and strong adaptability, and alveolar bone is the most active part of human bone metabolism and reconstruction.
Teeth move forward in the alveolar bone
Although the alveolar bone is absorbed, the cementum is not. Cementum is very resistant to compression, and under orthodontic force, it will not be absorbed or only a small amount of superficial cementum will be absorbed.
The wire on the teeth is what drives the teeth to move. Every arch wire is a stubborn warrior.
During the correction process, the dentist will also regularly adjust the arch wire to give it new strength. Therefore, in the process of orthodontic teeth, patients should cooperate with the doctor, have regular follow-up visits, and pay attention to prevent the brackets from falling off every day.
How to choose braces (aligners)?
About the quality of the appliance, we should not jump to conclusions. Each appliance has its own characteristics and needs, and everyone has a different definition of whether it is good or bad.
Network map invasion and deletion
The basic materials from orthodontic supply store are always available and easy to find them, from domestic to imported, from square wire arch to self-locking, from metal to single crystal.
Below is a list of the most common orthodontic appliances available today.
The current mainstream orthodontic appliances are roughly divided into fixed bracket appliances and invisible appliances.
Fixed bracket appliance
The brackets that fix the appliance need to be glued to the surface of the teeth and cannot be disassembled at will during the orthodontic process.
Fixed appliances are mainly divided into metal brackets and ceramic brackets according to different types of materials.
The most common and common are metal brackets.
Ceramic brackets are transparent versions of metal brackets, with a color similar to natural teeth. The advantages are better aesthetics and stronger bonding than metal brackets. As long as the doctor’s skill is good enough, there will be no problem of bracket falling off during treatment; In the process of tooth movement, the friction force is larger than that of metal brackets, and the movement speed is relatively slow.
According to different ligation methods, fixed brackets are divided into self-locking brackets and non-self-locking brackets.
Orthodontics is a highly technical diagnosis and treatment process, which requires advanced equipment for meticulous pre-operative examination and diagnosis. It also requires skilled doctors to formulate a reasonable plan according to each person’s dental condition, treatment time, aesthetic needs, economic level and other aspects.
Compared with the material, the technical level of the doctor is an important factor in determining the success of orthodontic treatment, and it is also a decisive factor in the price difference. The doctor’s plan design, and customized orthodontic laboratory cooperation occupies 60% of the importance, and the doctor’s operation occupies 30%!
