Plastic Braces in Astana: Price, Types, and Features

Bracket material and visibility on the teeth

Brackets are made from polymers — most often polycarbonate or composite resins. The material is matched to the enamel color, so the system looks less noticeable than metal. Metal braces are made from stainless steel or titanium alloy. They shine and stand out on the teeth. Ceramic braces are made from zirconium oxide or aluminum; they are close in shade to enamel but differ in transparency. Polymer can change color over time from coffee, tea, sauces, and tobacco. Ceramic and metal hardly accumulate staining. Visibility depends not only on the material but also on the thickness of the archwire, the type of ligatures, and hygiene. If a person often drinks staining beverages, plastic darkens faster. This affects aesthetics but not the mechanics of tooth movement. The doctor selects the system based on the clinical picture and the patient's request.

Strength and behavior of the polymer during chewing

Polymer is softer than metal and ceramic. During chewing and accidental loads, the bracket may crack or come off. Metal braces withstand pressure better. Ceramic braces are also strong but brittle under a sharp impact. Polymer behaves predictably only with careful handling. Hard food, the habit of biting nails or a pen, contact sports without protection — all of these increase the risk of breakage. If a bracket breaks, it is replaced or rebonded. This may delay treatment but does not cancel the plan. The speed of tooth movement depends on the clinical picture, not on the bracket material. Metal, ceramic, and polymer interact differently with the archwire and ligatures. The doctor assesses the bite, enamel, and gum condition, then suggests a suitable option. The patient can choose a system based on aesthetics and budget, but the final decision remains with the orthodontist.

Comparison of aesthetic systems by features

Archwire, slot, and force transfer to the tooth

The system is based on an elastic metal archwire. It bends to the shape of the dental arch and tends to return to its original position. The bracket is the attachment point through which this tendency is transmitted to a specific tooth. The body has a slot—a channel for the archwire. The slot matches its geometry, and when the wire straightens, it presses against the channel walls. This generates the force that pulls the tooth in the desired direction. Plastic acts as a transmission link: it holds the slot rigidly but does not create pressure itself. If the slot is displaced or rotated relative to the crown, the archwire will begin to rotate the tooth around its axis. Therefore, the bracket is positioned according to specified landmarks. The accuracy of placement determines where the tooth will move. Movement is slow: the bone around the root remodels under pressure, and this takes months. Timelines depend on the clinical picture, not the material. Plastic neither speeds up nor slows down the process—it merely transmits force, just like metal.

Ligated and self-ligating archwire fixation

Combination system: plastic in front, metal on the sides

Plastic is transparent but fragile. On the side teeth, chewing loads are higher, and it quickly wears down or chips there. Therefore, a combination scheme is used: plastic brackets on the front teeth, metal ones on the sides. In front, a smooth transparent row is visible; on the sides, metal locks. The archwire is single, passing through all brackets and transmitting force along the entire arch. The mechanics do not change: slot, archwire, pressure on the tooth. Only the material of the body changes in different areas. The scheme preserves aesthetics in the smile zone and does not sacrifice strength where the load demands it. The doctor decides how many teeth to cover with plastic and how many with metal, based on the bite and enamel condition. Sometimes plastic is placed only on the upper jaw, leaving the lower metal. This is also a combination option, and it occurs more often than a fully plastic system.

What determines treatment duration

First, the initial picture. Crowding of front teeth, deep or open bite, and displacement of side segments require different amounts of movement. The more teeth need to be moved and the farther, the longer the active phase. Second, age and periodontal condition. In adolescents, bone tissue remodels faster; in adults, processes are slower, and this is not a flaw of the method but biology. Third, hygiene and appliance integrity. Plaque at the bracket base causes gum inflammation, and then work with the active archwire is paused. A detached element also disrupts the schedule: the archwire does not transmit force, and the tooth stays in place. Fourth, discipline. Rubber bands, elastics, and removable elements work only with regular wear. Skipping lengthens treatment, and this cannot be predicted in advance. Fifth, the planned result. Sometimes it is enough to align the front; sometimes fine-tuning of occlusion along the entire arch is needed. The plan is reviewed based on control images, and the timeline is given approximately.

Guidelines by situation

Why the timeline differs in adults

In adults, the skeleton is already formed, and teeth move through dense bone. Remodeling proceeds more slowly than in a growing body, so the active phase is usually longer. Gum and bone condition add further considerations: recession, exposed tooth necks, and loss of bone support limit the speed and force that can be applied. Concurrent issues also interfere — crowns, implants, missing teeth. These are factored into the plan, and orthodontic treatment is sometimes carried out in stages, with pauses. Lifestyle matters too: adults find it harder to make time for visits, and a missed activation pushes back the finish line. Retention is a separate matter. After the appliance is removed, the result is maintained with a retainer, and this period is not counted in the active treatment time, although without it teeth tend to shift back. The exact duration in each case is determined by the doctor after examination and imaging, not by average figures from the internet.

Daily hygiene around the brackets

Diet and staining of the polymer

Polymer absorbs dyes. Not immediately, but over months of wear, light-colored brackets darken from coffee, strong tea, red wine, berries, and beets. Turmeric, soy sauce, and tomato paste also leave marks. Giving all of this up for a year to a year and a half is unrealistic, so it is wiser to drink staining beverages through a straw and rinse the mouth with water right after eating. Hard foods — nuts, croutons, pits, hard candy — are best crushed or not bitten at all: polymer does not withstand point loads the way metal does. Apples and carrots should be cut into slices, not bitten off. Sticky foods — toffee, nougat, chewing gum — pull on the archwire and ligatures, and a torn ligature shifts the bracket. Hot food by itself does not deform the polymer, but a sudden temperature change combined with load does no good. If a bracket does become stained, whitening toothpaste will not restore its original color — it only removes surface plaque. Replacing a bracket is a matter for the orthodontist, not household chemicals.

What to do about chips and debonding

A chipped polymer bracket or a detached bracket is no reason to panic, but it is also no reason to wait until a scheduled visit. A bracket without an archwire stops working: the tooth in that segment moves on its own, and the archwire may catch on the gum and cheek. Immediately after debonding, do not try to glue the bracket back on at home — superglue and household adhesives are toxic to the mucosa and damage the enamel surface. If the archwire is sticking out and cutting, apply orthodontic wax to the sharp end. Do not trim the loose end of the archwire yourself: wire cutters leave a sharp edge, and removing the archwire without tools is impossible. Report the breakage to the clinic and schedule a reinstallation; until the visit, brush your teeth carefully, avoiding the damaged area. If more than one bracket has come off, do not postpone the visit. A chipped base is treated by replacing the bracket, not by gluing the broken fragment back on. The decision is made by the doctor based on the clinical picture.

How a removable aligner differs from a fixed system

An aligner is a removable tray made of clear polymer. It is taken out while eating and brushing teeth. A braces system is bonded to the enamel and stays in the mouth for the entire treatment period. Hence the main practical difference: a tray can be lost or forgotten, while braces cannot. Plastic braces, unlike metal and ceramic ones, are also fixed, but their brackets are less noticeable on the teeth. Aligners are almost completely invisible. The tray guides rotation and tipping of a tooth through a series of successive models, each of which shifts the tooth slightly. A braces system pulls the tooth continuously via the archwire and ligatures. Hence the difference in sensation: the tray applies gentler pressure, while braces produce more pronounced tension in the first days. Hygiene is easier with an aligner — you take it out and clean it. With braces you need interdental brushes and a single-tuft brush, because plaque accumulates around the brackets. The prognosis depends on the clinical picture, not on the type of system.

When each option is considered

What the orthodontist decides at the consultation

Before starting treatment, the orthodontist gathers diagnostics: X-rays, impressions, an assessment of the bite. At the appointment they explain which systems will suit the specific case. The patient has the right to ask questions about timelines, hygiene and restrictions. If metal or ceramic is proposed instead of plastic, this is a calculation for the task, not a refusal of aesthetics. It is worth clarifying how often the components need to be changed and what to do if something breaks. A second opinion is also possible — that is normal. The plan should be based on diagnostics, not on promises. Then expectations match what happens at the appointments.

Why the result is retained after removal

A tooth is not held rigidly in the bone: a ligament remains around the root that allows it to move. When the braces are removed, this ligament retains a memory of the previous position for some time. Bone tissue remodels more slowly than the tooth shifts, so the fresh bone around the root does not become dense right away. If the tooth is left without support, it will start to shift back — this is called relapse. A retainer does not move the teeth, it simply holds them where they were placed. The risk of relapse is higher in the first months after removal, but it persists later as well. How strongly the teeth tend to return depends on the clinical picture: crowding, rotation of teeth around their axis, the depth of the bite, the condition of the periodontium. The doctor decides — they look at the initial position, at how the treatment went, and at how stable the teeth are by the time of removal. Sometimes the appliance is placed on only one jaw, sometimes on both. There is no universal rule.

Types of retainers

How long retention appliances are worn

There is no exact timeframe that is the same for everyone. In the first six months to a year after removal, the tray is worn almost constantly, taken out only for eating and hygiene. After that the regimen is usually reviewed: they switch to night-time wear, then to a few nights a week. A fixed wire can stay in place for years — it is not removed until the doctor decides it is no longer necessary. How long retention lasts depends on the clinical picture: age, the initial condition, the state of the gums, the rate of bone remodeling. Some finish after a year, others wear the tray at night for many years. If wear is skipped, the teeth will start to shift, and this is not immediately noticeable. Sometimes they can be moved back with the tray, sometimes not — then re-treatment is discussed. That is why the regimen prescribed by the doctor should not be changed on your own. Follow-up check-ups after braces removal are needed to notice a shift in time and adjust the plan.

The material and its limits

Plastic is a polymer. It is transparent or tinted to match the enamel, so the appliance looks less noticeable than a metal one. But the material is softer than steel and ceramic. The surface scratches more easily, may become cloudy over time, and staining from coffee, tea, sauces, and tobacco clings to it more readily. Strength is lower: when removing elastics, working with the archwire, or from an accidental knock, a bracket can crack. This does not mean the system is bad. It means it is chosen for a specific clinical picture, not for appearance. If high load resistance is needed, the doctor will suggest another material. If aesthetics matter more and the bite allows it, plastic is considered. It is more honest to discuss the material's limits before placement, not after a breakage. That way the decision is calm and without disappointment.

Duration and care

Treatment duration is not tied directly to the material. It depends on how complex the movement to be achieved is and how the tissues respond. One case is finished faster, another takes more time. Specific months cannot be named in advance — the doctor decides based on X-rays and as treatment progresses. Care affects the condition of the appliance. Use a soft toothbrush, an interdental brush sized to the bracket, and non-abrasive toothpaste. It is best to limit staining drinks and rinse the mouth after eating. If a bracket comes loose or cracks, do not wait for a scheduled visit: the part is replaced, otherwise the archwire loses its action. Retainers after removal are also part of the work. They are worn according to the schedule prescribed by the orthodontist, and skipping them reduces the result to nothing.

The Doctor Makes the Decision

Choosing a system is not a matter of taste. The doctor looks at the bite, bone density, gum condition, hygiene, and age. Plastic is not suitable for everyone: in some cases it will not withstand the needed load, in others it will interfere with hygiene. The patient has the right to ask about options and hear the reasoning. But the final decision rests with the specialist managing the case. If metal or ceramic is suggested, it is not a refusal of aesthetics but a calculation for the task. If plastic is suggested, it is worth clarifying how often the parts need to be replaced and what to do if one breaks. A second opinion is also possible — that is normal. The main thing is that the plan is based on diagnostics, not on promises. Then treatment proceeds smoothly, and expectations match reality. Hygiene is discussed separately: it determines how long the parts keep their appearance.
