Abstract
A Dental Brace, for repositioning crowded teeth, improvement/correction in spacing, alignment and bite. Its shape resembles letter A; instantly differentiating it from previous dental braces/orthodontic appliances and prior art. Its also different because its self-adjustable, removable, simple/autodidactic to use, efficient and inexpensive. It is worn by gently biting over knobbed bits that are attached to arms that together are supported between the maxillary and mandibular teeth and lips, but for the most part it sits outside the mouth. The bits are moved apart with pivoting nut-pins connected to a control crossbar, which when turned, adjusts to create pressure on selected and surrounding teeth. The arms are secured together with a spring and the crossbar housing. Its a multi-faceted orthodontic tool, specifically for basic straightening out of overcrowded teeth, by pushing particular teeth outward, however, its also reversible which gives it the ability to close gaps and push-in odd protruding teeth.
Description
Title: A DENTAL BRACE Specification
The A Dental Brace relates to every basic type of orthodontic appliance (see Claims) and compares as a manual-operable dental grooming device, specifically used to realign the positioning of ones' own teeth and bite, in order to correct or improve basic orthodontic problems.
Description of Prior Art:
Conventional metal dental braces/appliances have generally been comprised of a plurality of brackets, bonded onto teeth with adhesive, and attached with arch-wire and a force-generating device for achieving various types of desirable forces upon the teeth of a patient, by an Orthodontist. In 1999, Invisalign braces were introduced, which are a series of clear, custom-molded plastic, removable aligners that are replaced every two weeks or so, until the desired results are achieved.
The main problems with both of these prior orthodontic designs are listed below, starting on the following page (pages 5 and 6).
Background of the Preferred Embodiment.
The intrinsic foundational concept in making this dental brace came from a wise teaching from my best former neighbour; a retired 45yr-career airline maintenance engineer, Albert W Bock, who taught me (20 years ago) that I (and anyone else) could make any tool needed that couldn't be bought from a store. This lesson occurred because the Vancouver hardware stores at that time, did not sell the rare screwdriver we needed to fix my 'Made in France' car, as it was only available for licensed mechanics to order and buy. Orthodontics for me was a similar case.
In its mid-development, the A Dental Brace was enrooted with my sister Carol's proven theory that, with just 10 minutes of pressure per day, for about a year, is all that is needed to correct imperfect spacing between teeth [in her case, she closed a gap between her two front teeth (maxillary central incisors) by cleverly applying pressure with her nailed thumb and index finger] . According to dentists and orthodontists, at least six (6) hours of consistent pressure are needed on teeth before any permanent movement will occur. According. to the mathematics in these two proven theories, six hours divided by IO minutes per day equals 36 days, to which a user can expect to see definite results and earlier, if pressure is applied more than 10 minutes per day.
By far, the most common and comparable dental braces are metal, but for many patients they cause multiple problems, which are numerically listed in this section. The A Dental Brace should not give its users any experience of those onerous burdens, as * indicated:
1. When metal braces are first put on, most patients suffer from soreness and pain for several days and again after each adjustment (every 3-8 wks), until the last month (every 1-2 wks) of the duration.
* The A Dental Brace is applied and adjusted by the user; it is tightened to just the right comfort level, decreased in tension (loosened) if discomfort occurs, and increased again when pressure subsides, plus it can be removed at anytime!
2. With metal braces, brushing teeth must be done very gently and extra thoroughly around all the brackets and under the connecting wire. Those who don't brush often and thorough, will develop yellow stains around the brackets and have white spots on their teeth after the braces are removed, often more than two years later. Flossing is a very tricky chore, though a Floss Threader may help.
#■ Thorough brushing and flossing are always completed before applying the A Dental Brace.
J . Many wearers of metal dental braces say they are not able to eat solid food during the first few initial days and then again after the regular adjustments, because it's just too painful.
* The A Dental Brace must never be worn when eating. Users should expect to experience a very pleasant, clean/fresh-mouth lingering sensation that naturally prefers not to be interrupted by the presence of food, making this brace a bonus tool for anyone wanting to cut down on eating and reduce weight. This pressure-cleaned-mouth inclination will also aid in healing gum disease, which many medical studies have shown to be a major contributor to many serious illnesses such as heart disease, pneumonia/ respiratory diseases, cancer, pregnancy complications, diabetes and several others as stated by individual dentists and medical experts.
4- Metal brace wearers are banned from drinking sodas, as it melts the cement adhesive which adheres the metal brackets onto the teeth.
* The A Dental Brace is easily removed to drink water (only) during a session, but outside of a session, users may drink whatever they want.
5. Wearers of metal braces cannot bite into simple hard fruits and vegetables such as an apple or cucumber, which have to be cut up first. Other foods such as popcorn, nuts, carrots, chips, cookies, candies, etc are forbidden because they get stuck and can cause serious damage to the metal braces. Many other gummy foods are discouraged because the braces/brackets/teeth and prone to collect debris and sticky food within.
* Eating does not occur while wearing the A Dental Brace, so no such restrictions.
6. Wires from metal braces can cause scrapes and cuts to the tongue and insides of the mouth, and if present, thrush will cause additional discomfort and pain. Gum Wax is often used to prevent it.
* The A Deπtαt Brace is worn between the maxilla and mandible in a grip-like stable position, with no chance of chewing or talking, so rubbing should not occur.
7- Frequent orthodontic visits may reduce problems and can speed progress but they are costly, inconvenient and have to be reserved in advance.
* The A Dental Brace is completely controlled by the user; so monthly visits fo an orthodontist may not at alt be necessary, except for consultation and diagnosis.
8. Gaps between teeth that are closed too quickly with metal braces can cause inflammation that sometimes results in surgery after the braces are removed.
* Gums and teeth are always fully cleaned before using The A Dental Brace, so food and bacteria doesn't get stuck in the gums during tooth movement, which would otherwise cause inflammation.
9- Gum recession often occurs from wearing metal dental braces.
* Gum recession won't develop from properly wearing the A Dental Brace, which actually may reduce gum recession by straightening out crooked recessed teeth.
10. From a distance, clear braces look like plaque on teeth, and they can stain from certain beverages and food. Coloured braces can look weird. Embarrassment and teasing usually do occur.
* The A Dental Brace is specifically designed for wearing within ones' own privacy.
11. Spacers/separators are often required two weeks before wearing conventional braces, and are said to hurt more than braces.
* Separators /spacers are not necessary before wearing the A Dental Brace, though they certainly may be helpful and perhaps needed for problematic teeth.
12. A common practice in modern orthodontics has been to have all four (4) wisdom teeth
(3r molars) pulled out before treatment, because it has generally been thought that most wisdom teeth (in their very hard to reach areas) impede sufficient room for straightening up the main teeth.
* The A Dental Brace does not require wisdom * teeth to be pulled. (* Omitted in drawings)
13 • Kissing can be very awkward when wearing metal dental braces.
* It's impossible to kiss when wearing the A Dental Brace, but it can always be removed immediately.
14- As an alternative to orthodontics, veneers require that the teeth be significantly ground down before the porcelain facades can be adhered. Users are then committed for the rest of their lives. Unfortunately, many need to be redone every 15 years or so (more cost and inconvenience).
* As the A Dental Brace was made to reposition crowded and gapped teeth, it benefits aesthetically by widening and aligning the row-of-pearly-whites in a smile. It won't artificially cover-up problems, but it can naturally beautify a smile.
15- Modern orthodontics typically cost too much for the average person; $3,000 - $10,000 (CAD) for metal braces, $5,000 - $7,000 for Invisalign™ braces and $625 - $845 per tooth, for porcelain veneers
*■ The A Dental Brace is a do-it-yourself, one-size-flts-all kind of tool (2 or 3 sizes only need to be manufactured) and is not custom-fitted or made like all other present day orthodontics. Its simplicity should make it very affordable and attainable for anybody wanting to reposition their own teeth and greatly improve their own smiles. (See more under Novelty)
(Description of ^Drawings
To wear the A Dental Brace {Figures I and 3 }, the user must first adjust the tension-control crossbar {D/ by turning the attached control-knobs {H2 - Figure i} or dial {Hi - Figure 3}, so that the arms {B} are at an appropriate width to where the user can easily bite down over and around both knobs {Cl} of the two bits {C} that are each secured to one end {Bl or B2} of each arm {B}, as shown in Figure 5 (only the upper arch is drawn but the lower arch also corresponds to support the bite onto the bits{C}) .
A spring {A} holds the arms {B} together at one end {either Bl or B2}, opposite of the bitted ends {Bl or B2} and it serves as a gentle suspension, as tension is created on the treated teeth within a firm, yet relaxed bite.
The knobs {Cl} of the bits {C} function together as grips to hold the dental appliance in place between the maxillary {Figure 5, 6} and mandibular teeth, which together support the pressure created from adjusting the control crossbar {D}, from the moment of force on the teeth. The two bits {C} are each symmetrically attached to the inner ends {Bl or B2} of the arm's {B} core rods {E} with fasteners {i}, at 90°-135° angles as shown in Figures I, 3, 4, 5. 6 and 7-
The arms {Si may be reversible/interchangeable in order to change the angle of the bits {C}: a 90° angle {Bl - Figures I, 3 and 6} is for treating bicuspid and molar teeth, and a 135° (approximate) angle {B2 - Figures 4. 5 & 7} is for treating canine and incisor teeth. The bits {C} are also reversible {C2 - Figure 6} for those wanting to push in gapped and odd protruding teeth.
The crossbar {D} and its corresponding hardware {F, Gl, G2} serve together as both a pressure-control device and a safety feature of this appliance. Without it, the brace would otherwise be U or V shaped {Figure 7}, which is not recommended because the spring {A} (coil, torsion, etc) gives constant pressure that becomes exceedingly agitating to the user, from no relief or variance in the incessant tension (more under Inventiveness). The crossbar {D} adjusts and controls the amount of pressure from the bits' knobs {Cl/ positioned to push gently against the teeth, h {D} is male-threaded and andpocie on either side, which makes it screw clockwise (direction of all regular screws) from one end {D2} and counterclockwise on the other {DI }, each side fitting into one of the two (2) antipode. female-threaded nut-pins {G2 and Gl}, which are secured to the mid-section of the arms {β} through the correlating centre holes {F I } in each arm {B - Figure 3}, or the vertical holes {Fi} in the attached brackets/clamps {F - Figures I and 2} on each arm {B — Figure i}. The two nut-pins {Gl and G2} are short round rods that have been drilled and tapped through the sides and revolve like hinges, for the fastened crossbar {D} to turn in its housing {F and Fl }, which altogether adjusts the width between the two (2) bits {Bl or B2} of the A Dental Brace.
OfoveCty
Four essential keys to the development and design of The A Dental Brace have been: affordability, efficiency, a do-it-yourself style and simplicity.
In Canada and the United States, orthodontic appliances typically cost thousands of dollars [$2,600 USD for aligners plus $I,000-$5,000 for orthodontist visits], which is beyond most peoples' affordability. In Canada, in almost every case orthodontic appliances are paid with a contract of credit and down payment.
Up until now, most adults who require braces and can afford them have tended to go without, due to the embarrassment and inconvenience of metal braces. The A Dental Brace shall be a choice alternative to both Invisalign™ and metal orthodontic appliances, because of its removable, convenient method of use within a private manner, its simple efficient effectiveness, self-adjustability and its benefactory, value saving, low cost. The price of The A Dental Brace shall be a mere fraction of the current costs associated with modern conventional orthodontic braces. In most cases, it will cost approximately 100-300 times less, giving everyone including the underprivileged, the opportunity to straighten their teeth and greatly improve their smiles.
Inventiveness
This section is a little embarrassing but it proves without a doubt the great lengths I went through to invent and refine the A Dental Braces, and I am including it for the purpose of shear protection from any hacker who may have stolen my digital, invention patent document before my filing date (as I had experienced) and for anyone else's curiosity, general interest and/or inspiration.
The A Dental Brace started from my own desire to correct my slightly crowded teeth (with a minor, maxillary, central incisor overlap and overbite), so that:
* I could laugh and smile freely; with full confidence at anytime, without any hesitation, thought or embarrassment of the above,
* I could floss easily between all my teeth without getting the floss stuck and breaking off between two very overcrowded maxillary molars.
* I could have an improved, easier-to-look-at, and indeed, even a beautiful smile, without the costs or hassles associated with modern orthodontics.
My very first experimental prototype in the summer of 2001, consisted of dental floss that was tied into small loops and tourniquet-twisted between a selected tooth (or couple of teeth) and genuine Q-Tips (stiffer than other brands) that were erected against my lips to create tension, with extra cotton padded under the pressured force to protect my lips. As I experimented, I endured big red swollen lips throughout that summer (a cheap and desperate alternative to Botox-injected lips).
The second prototype allowed me to treat more teeth at one time, using a row of built-in hooks for the floss loops to hook onto. It was formed from a row of uniform 1/4" holes in a strip of plastic/metal eaves-trough screen, which was cut through to make the hooks. The fashioned strip of hooks was fastened around the recessed chin-rest of a Philadelphia ® Tracheotomy (cervical) Collar (US Patent No. 4,677,969). The hooks had replaced the Q-Tips, and in order to create tension, the altered front side of the neck-brace had to be pulled away from the face. I could add some extra comments here, but I must say I had a driving understanding that the concept did indeed work.
The third prototype was a U-shaped brace using the same idea as the second, minus the neck brace. It had handles at the end of each arm of the U that were used to pull the brace away from the teeth/face. It worked but barely, and was riddled with serious problems besides being awkward, bulky and ugly like its predecessor.
The fourth prototype and first significant milestone was the big change from tie-ups and hooks, to 'bits' that were made from the ends of small wooden bobbins and fastened to the inner sides of my U-shaped brace.
The next breakthrough came in making the arms thin enough to go right into the mouth, along with the bits. Then a coil spring was added between one end of each arm, holding them together while creating the first new independent and automatic tension for the brace.
In realizing the effectiveness of this evolving dental brace through my own tests and trials, it became obvious to me that it would have to be mass-produced to give everyone (including myself) an affordable chance to have their teeth properly straightened too. So, in order to prevent this brace (Figure 7 with a coil spring instead of a torsion) from springing out of just anybody's mouth, or slipping off their bite and springing wide-open into their inner cheeks, a safety control device was needed between the two arms.
After various experimenting, I recognized the "magic" of a typical turnbuckle from the hardware store and knew it held the answer to a perfect safety device. As a triple bonus, it would also become a great new way to totally control and vary the pressure, and now could even be reversed for those wanting to push teeth inward. The turnbuckle was turned "inside out" by welding its two antipode eyelet screws together to form one straight adjustment screw (crossbar) with a turning device (dial) at its center, made from the bent and cut-in- half eyelets. Round nut-pins were cut from each female-threaded, antipode end of the buckle, to correlate with each end of the new crossbar. The arms of the brace were then modified (with custom help from a wood-turner) to house these revolving nut-pins, which fastened to the crossbar that now altogether held the arms safely together. Hence, the self-adjustable, A-shaped dental brace was formed!
The coil spring was replaced with a torsion spring for a superior suspension and improved tension. Later, clamp-type brackets were added to (an old version of) the arms to simplify efficiency in the crossbar housing, due to manufacturing difficulty with concerns about using petroleum based plastics.
Each of the many previous embodiments of this invention has always been a faithful and very encouraging step up and forward to refine the efficiency and effectiveness in the evolving, perfect little A Dental Bf ace.
Claims
1. The A Dental Brace is a personal orthodontic tool comprised of two (2) rod arms joined flexibly together at one end (with a spring, pivot, tied-together or otherwise), with the opposite ends each secured with knobbed bits that when a user bites down on/over together, are then spread gently apart (which applies pressure on affected teeth, by pushing them outward to create appropriate space for overcrowded teeth to realign) by the force of a spring or by turning an applied antipode-threaded adjustment-crossbar screwed into pivoting female antipode-threaded nut-pins housed across the mid-section of the arms.
2. The orthodontic brace of claim 1, wherein can be reversed for treating gapped and/or protruding teeth, by reversing the bits (Figure 6) and turning the crossbar in the opposite direction, to apply pressure in order to push teeth inward (as opposed to outward in claim 1).
3. The orthodontic brace of claim 1 and 2, when applied, treats both the maxillary and mandibular teeth together (as the bits are positioned between them), which helps to realign the bite (studies show that 65% of the world's population has an overbite) as teeth are moved, making this brace a considerable alternative to various headgear in the treatment of over-bites and under-bites, in addition to serving as an orthodontic retainer and a palate expander.
As well, the brace tends to flex the airways (nostrils) of its users, ameliorating deeper breathing, which improves well-being.
The A Dental Brace is to be worn in a clean mouth, while awake, for short periods of any length, eg: 10 minutes, two hours or even six hours spread throughout the day. It can be worn every day, but the user may skip days and wear it whenever it's convenient and timely.
Users themselves can position, adjust and reposition the A Dental Brace at any time using the dial or control knobs of the crossbar. The pressure can be measured with each turn of the crossbar from the moment of force (M/F ratio). Orthodontists usually use a 10-12 M/F ratio when adjusting/tightening orthodontic appliances, but they may use between 8-20 M/F ratio-pressure units, hence, this measurement from M/F is very seldom used or measured, if ever. The tension of the A Dental Brace can easily be reduced whenever it's too tight or uncomfortable, and the brace can be removed from the mouth at any time.
In understanding how the A Dental Brace affects the rows of teeth, compare a row of teeth to a single row of un-mortared, interlocking bricks laying flat, next to each other, with the whole row needing to be inoved slightly sideways - - you don't have to push each brick in order for the row to move, you only have to push every other one or so, and the surrounding bricks move along with it. The A Dental Brace treats teeth (gently) in this manner, using the same sort of theory.
A maxim rule for all users to follow is always have fully cleaned teeth, gums and mouth before wearing the A Dental Brace. Thorough brushing and flossing are absolute prerequisites that should facilitate to instill good, lifelong, oral hygiene habits for all regular users. Medical studies prove that good oral hygiene is absolutely essential in overall good health.
The results from positive realignment of teeth will definitely boost self-confidence and give encouragement to each and every eager, gentle and amenable participant.
A nicer smile is pretty much guaranteed for each of them!
