Who invented the orthodontic retainer?

Hawley, the lip wire, or Hawley bow, incorporates 2 omega loops for adjustment. Anchors on an acrylic base plate that sits on the roof of the mouth (roof of the mouth). There was a time when teens and adults alike trembled at the thought of having to put on braces. The moment a dentist recommended seeing an orthodontist, the words “metal mouth,” tin teeth, and other unattractive adjectives crossed people's minds.

Today, with new technologies available, people of all ages choose orthodontic treatment to achieve a beautiful and healthy smile. Orthodontic evaluations are generally performed on all children between 6 and 10 years of age. By the time most children are 12 years old, they already have all their permanent teeth and can receive orthodontic treatment. Many older patients now seek orthodontic treatment to correct their misaligned teeth, but they don't want to go through traditional wires and braces; hence the introduction of clear aligners.

Braces take advantage of basic engineering principles. A gentle and constant pressure in the direction of the desired movement will allow for a general change in tooth position. As pressure is applied to the periodontal ligament, which holds the teeth in place, the body will automatically create space in the new desired location while filling the space where the teeth used to be located. If too much force is applied at once or in a short period of time, tooth loss is possible.

This is the reason for the need to make small changes approximately every 30 days for the duration of treatment. Undoubtedly, the movement of teeth through orthodontic treatment must be constantly monitored and adjusted. While every patient is different, movement of 1 mm per month is usually possible with orthodontic care. Traditional orthodontic appliances are usually worn for two to two and a half years, depending on the degree of orthodontic treatment needed.

When a lot of movement is needed, longer-lasting care may be needed. Conversely, a small amount of movement of the denture will require a shorter period of time. Because braces require regular adjustment (in addition to the initial application), the cost of orthodontic treatment is somewhat higher than many simple dental procedures. Traditional braces will cost between three and six thousand dollars in the United States.

Although orthodontic insurance coverage was a rarity years ago and is not yet included in many policies, some insurance companies do pay a portion of orthodontic care. Archaeologists discovered many mummified remains in and around Egypt, so researchers believe could have been an early attempt to close gaps in teeth. These scraps have a cord made of animal intestines (known as catgut) that wraps or extends along the teeth in a style much like modern orthodontists pass orthodontic wire along the teeth in an effort to close the gaps. The Etruscans lived in Italy and its surroundings between 770 a.

C. and 270 BC, and they were the predecessors of the ancient Romans. The Etruscans had extensive burial rituals that involved preparing the body for the afterlife, before burying it in a tomb. Archaeologists discovered that part of the burial ritual included placing a device similar to a mouth guard in the mouth of the deceased.

This was done to preserve the space and prevent the teeth from collapsing inwards, so that the deceased looked good when they entered the afterlife. The bridges were made of pure gold excavated at the ancient site of Satricum, in central Italy. A significant discovery is that Etruscan bridges were only used by women, implying that cosmetics and vanity were major dental concerns. Aulus Cornelius Celso was an ancient Roman who dedicated his life to studying and discovering new medical procedures.

Celsus kept a detailed account of his work, and holds the first recorded attempt to straighten or move his teeth using finger pressure. Celsus documented a case involving applying finger pressure to the teeth at regular intervals. Through detailed notes and recordings, Celsus hypothesized that teeth moved slowly and realigned due to prolonged exposure to finger pressure. Romans invented a dental device that resembles modern orthodontic dental devices.

Archaeologists opened many Roman tombs only to discover that some of the deceased's teeth had a small gold wire, known as ligating wire, that was used to fix the wire bow to the support. The wire was tied to the teeth in an effort to force the teeth to move and close noticeable gaps. Although there is no documented date, this process was probably before the beginning of our era. The Surgeon Dentist is a medical book published in 1728 by Pierre Fauchard.

Fauchard was a French dental surgeon known for his innovative approach to dentistry. The Surgeon Dentist documented numerous topics in general dentistry, but what made the book stand out in the world was a particular chapter dedicated to orthodontics. The chapter explored several ways to straighten teeth, but focused mainly on a relatively new concept involving the “Bandeau”. The “Bandeau” is a dental device that looks like a horseshoe.

This device was inserted into the patient's mouth to keep the natural arch of the teeth and mouth in place. The Dentist's Art is a medical book written in 1757 by the dentist to the king of France. Pierre Bourdet dedicated a section of the book to exploring several methods that could be used to improve tooth alignment. Two medical theories were monumental in The Dentist's Art.

The first monumental discovery was the theory that teeth in the back of the mouth (wisdom teeth) could be removed to avoid overcrowding, which was the main cause of tooth misalignment. The second discovery was the improvement of the “Bandeu” device. Pierre Bourdet wrote extensively about how the device could be improved from its original concept. The first official use of the word “braces” was in the early 20th century.

While the name may remain the same as the technique used in modern dentistry, the technique and devices used in orthodontics advanced considerably during the 20th century. The braces of the early 20th century were dramatically different from the braces that people think of today. Dentists would wrap individual bands (assorted materials) around each tooth. The bands would then be connected by a cable.

The wire can be adjusted to apply pressure to the teeth in the hope of slowly moving them into proper alignment. There were no set standards in terms of what type of materials were used when the first set of keys was created. Some dentists used ivory, while others used wood, copper, or zinc. The materials used were completely dependent on the dentist's personal preference, the patient's budget, and what was available in the geographical area at the time.

However, there was one material preferred by dentists around the world: gold. Many dentists preferred gold because the material is extremely flexible when heated. Gold can be shaped and shaped to wrap around teeth. Materials such as wires, bands, brooches and spurs are made of 14 and 18 karat gold.

While gold was preferred, it was not commonly used for several reasons, mainly because of the price and the frequent adjustments that were required. Gold was extremely expensive even in the early 20th century, and not all patients could afford the extra expense. In addition to the price of gold, patients who had gold orthodontic appliances needed frequent adjustments by the dentist, as the material often began to soften due to body heat. Patients who couldn't afford to buy the gold used for braces often had to use the dentist's second material of choice: silver.

Silver was significantly cheaper than gold, but not as flexible. However, alternative materials, such as ivory and wood, were preferred, which were extremely difficult to work with at the time. Orthodontic techniques remained relatively the same until the 1970s, when numerous innovative techniques were discovered. The most innovative technique was the use of a dental adhesive to attach dental braces to teeth.

A dental adhesive was placed on the surface of the teeth, where the braces would “stick” directly to the teeth. This technique replaced the need for dentists to wrap an individual wire around each tooth to keep the braces in place. In addition to dental adhesive, tie wires and elastic ligatures were often used to keep orthodontic appliances tight and in place. The use of stainless steel, rather than gold or silver, was part of the improved dental techniques used for braces in the 1970s.

Stainless steel became popular in the 1960s, but it wasn't until the mid-1970s that dentists began incorporating the material into their dental practice. Stainless steel was a relief for both patients and dentists; patients were happy because it reduced the cost of braces, while dentists liked it because it was extremely flexible and easy to handle. The 1970s also saw the first attempt to use “invisible” braces. People wanted an alternative to unsightly cables and helmets.

Dentists in Japan and the United States began experimenting with the possibility that dental appliances could be applied to the inside of the teeth, rather than the outside. Placing braces on the inside of the teeth allowed people to get the benefits of braces without having to make people see the physical braces on their teeth. The concept of invisible keys was of great interest and study between the 1970s and the early 1990s. But it wasn't until 1997 that a technique emerged, discovered by two people who had no dental training, that was widely accepted by orthodontists around the world.

Zia Chishti, a Stanford University graduate with no medical or dental history, discovered that her teeth began to move when she wasn't wearing the clear plastic retainer that was part of her orthodontic treatment. When the transparent retainer was placed back in the mouth for several days, the teeth slowly returned to proper alignment. Chishti took his discovery and partnered with Kelsey Wirth (another Stanford graduate, and an investment banker for Robertson Stephens) to create a method that combined 3-D computer technology with plastic retainers. 3D technology would take several images of a patient's teeth and show the slow progression needed to realign teeth correctly.

The slow progression of the teeth toward correct alignment would be assigned a number or stage. Each stage of the progression would be represented by a different transparent plastic retainer that the patient would use for a specific period of time. The different transparent plastic retainers would move slowly and move the teeth into place, which is similar to how braces work. However, instead of having cumbersome braces attached to your teeth, transparent retainers did the job and no one noticed them.

Several companies have started incorporating the Invisalign technique into their product. Clear Correct uses 3D computer imaging, plus several transparent retainers to slowly bring teeth back into correct alignment. Patients wear the retainers for the specified time and exchange them for the next transparent retainer. Clear retainers are designed to slowly move or change teeth so that they are properly aligned.

When braces were invented, they were a dental device that was normally reserved for the wealthy or those with extreme cases of orthodontic deformations. Today, orthodontic appliances are considered a routine dental procedure that many children and adults undergo to beautify their smiles and improve their oral hygiene and overall health. The American Orthodontic Association, which is the organization that presides over orthodontists in the United States, has released some dramatic statistics regarding the popularity of orthodontic appliances in today's society. Orthodontic appliances have come a long way since the first use of a small catgut cord to slowly move teeth into proper alignment.

In fact, there have been so many advances in the techniques used that it is difficult to imagine that, after almost 3,000 years of progress, there may be room for growth in the world of orthodontics, but there is. Orthodontists predict that the popularity of seeking orthodontic treatment will only increase as both the cost and duration of treatment decrease. Some research suggests that it is possible that the use of stainless steel for orthodontic treatments may be replaced in the coming years. Special Heat-Activated Nickel-Titanium Metal Discovered by NASA Could Be Next Big Breakthrough in Orthodontic Treatment.

Researchers believe that this metal, which can be cast into a small wire, can improve the alignment of teeth in the mouth. This metal could eliminate the need for people to undergo multiple orthodontic visits just to realign or tighten their braces. According to an article in DentistryIQ, two inventors have invented an orthodontic retention system that uses magnets. In the field of orthodontics, it is best known for its introduction of a refined type of retention plate called the Hawley Bite Plate.

A recent systematic review failed to identify any clinical studies evaluating the effects of LLLT in preventing relapse after orthodontic treatment. In addition, collagen synthesis was markedly higher when LLLT was applied as an adjunct to the fixed orthodontic retainer, compared to LLLT alone. Hawley's Determination of the Normal Arch and Its Application to Orthodontia and An Accurate Method in Orthodontia articles were read prior to the 4th International Dental Congress and the New York Institute of Stomatology. With children and adolescents, semi-permanent accessories, such as orthodontic braces, wires, and even palatal expanders (Fig.

Orthodontic treatment used to be considered “cosmetic,” but today, dentists and patients alike realize that orthodontic treatment can be a necessity. Advantageously, the substantially L-shape of the delivery member allows an orthodontist to enter only a small portion of the patient's oral cavity to place the dental modules in a patient's teeth. . .
