Dental crowns in Astana: types, prices, placement

When it's time to replace the restoration

What happens at the appointment

Can replacement be avoided?

Sometimes a crown is not remade but recemented. This is possible if the restoration itself is intact, the margin fits tightly, and the tooth underneath is healthy. Then it is removed, cleaned, the abutment is treated, and it is seated back on fresh cement. Another option is repair: a chipped piece of ceramic is restored with composite directly in the mouth. This solution is temporary but allows you to wait for a planned replacement. When there is decay under the crown, a root crack, or severe tooth destruction, a minor fix won't work. Recementation here would only mask the problem. The doctor decides based on the X-ray and clinical picture: sometimes recementation is enough, sometimes a new restoration is needed, and sometimes root canal treatment or extraction is required. There is no universal answer — it all depends on the condition of the specific tooth.

What influences the further choice

Diagnostics before prosthodontic treatment

Before starting work, the dentist examines the oral cavity and assesses the condition of the abutment teeth. This requires not one instrument, but several. An intraoral scanner produces a digital model, a periapical X-ray shows the root and bone tissue, and a panoramic image covers the entire dental arch. A panoramic radiograph helps identify hidden sources of inflammation, cysts, and impacted teeth. Additionally, a CT scan may be needed if implantation is planned or there are doubts about the anatomy. Each method answers its own question, and the dentist determines the set of examinations. Sometimes an examination and a single X-ray are enough; sometimes the full scope is needed. At this stage, the clinic is only gathering data, and the price consists of diagnostics, the technician's work, and materials. A diagnostic error costs more than an extra X-ray.

How the impression is taken

How the restoration is fabricated

Why the bite is checked after cementation

After placement, the crown is checked for occlusion. Articulating paper shows where the tooth contacts the antagonist and where the contact is too strong. Excessive load on the restoration is felt as discomfort when chewing and over time leads to chipping and mobility of the abutment. Too light a contact is also bad: food is not ground properly, and the adjacent teeth become overloaded. The dentist adjusts the surface with burs and rechecks the closure. The procedure takes a few minutes, but it is precisely what determines how the crown behaves in the oral cavity. Sometimes the bite is adjusted over several visits if the patient is getting used to the new height. The lateral and forward movements of the lower jaw are also assessed separately: there should be no premature cusps there either. The lateral and forward movements of the lower jaw are also assessed separately: there should be no premature cusps there either. If after adjustment there is still a feeling that the tooth contacts first, you should tell your dentist about it.

Home hygiene at the margin

What to do about the spaces between teeth

If two crowned teeth are next to each other, there is almost always a gap between them. Floss does not pass through or tears because the crown margin is wider than the tooth itself. For such places, there is superfloss with a spongy thick section and interdental brushes sized to the gap. The thread is guided under the margin, wrapped around the tooth wall, and pulled outward — not yanked upward, otherwise the margin can be dislodged. The brush is chosen so that it goes in with slight resistance and does not bend. If food constantly gets stuck between the teeth, mention it at your check-up: sometimes it is due to the shape of the space, and it can be corrected. Plaque also accumulates between a bridge restoration and the gum, so a long-handled interdental brush or floss with a stiff tip works there. The space under the pontic of a bridge is rinsed with an irrigator on medium power, directing the stream along the gum, not across it.

Check-up visits

You leave the office not with a finished result, but with a restoration that needs to be checked. Every six months, the dentist examines the margin, the bite, and the condition of the gum around it. At a check-up, you can see what is not visible in the mirror: a gap under the margin, chipping of the ceramic, mobility. The dentist also checks separately whether the crown is wearing against the adjacent tooth — this is noticeable in the bite earlier than in sensations. If bleeding, odor, or a feeling of pressure appears, do not wait for the scheduled visit. Anterior crowns chip more often, so they are examined more carefully. Come for a check-up even when nothing hurts. During the appointment, plaque around the margin is removed, the fit is checked, and contacts are tightened if necessary. An X-ray is not taken every time, but according to indications: if the dentist sees a reason or the patient complains of pain under the restoration.

What depends on the clinical picture

Purpose of a temporary restoration

A temporary crown covers the prepared tooth while the permanent one is being made. It protects the prepared tooth from chipping and overload, keeps the gum from shifting, and prevents adjacent teeth from drifting into the gap. Meanwhile, the patient can chew, speak, and smile without a gap in the mouth. The material is soft, so you should not chew hard food on this restoration. It is cemented with temporary cement and can be removed without cutting. The shape and color are chosen to match the future permanent crown. Appearance during wear is not the main priority, but it should not be neglected either. If the prepared tooth is severely damaged, the temporary restoration is held on a post or a core build-up. Sometimes it is used as a diagnostic tool: the patient wears it for a week or two and says whether the shape is comfortable. Then the permanent crown is made with adjustments. The load is distributed so as not to overload the abutment. The dentist decides whether a temporary restoration is needed in a particular case.

What temporary restorations are made of

When the permanent crown is placed

The permanent crown is cemented when the prepared tooth is ready, the gum has settled, and the bite has been checked. Before that, the temporary crown is removed, and the marginal fit and color are evaluated. If the gum is swollen after preparation, placement is delayed — the margin must sit on healthy tissue. The material is chosen for the area: on posterior teeth, metal-ceramic or zirconia is more common; on anterior teeth, ceramic or zirconia. It is cemented with permanent cement, and such a restoration can no longer be removed without cutting. After placement, the occlusion is checked; otherwise, the abutment may be overloaded. The service life depends on hygiene, bite, and material, not just on the type of restoration. If a vital nerve remains under the crown, this is taken into account during preparation. With an implant, the permanent crown is placed after osseointegration, as a separate stage. The decision on when to cement it is made by the dentist based on the clinical picture, not the calendar.

Differences by characteristics

Structure of metal-ceramic

The base of the crown is a cast metal cap. Ceramic is layered onto it and fired in a furnace. The metal bears the chewing load, while the ceramic gives the tooth color. Because of the framework, the crown is dense and opaque: light does not pass through it the way it does through living enamel. Over time, a dark line may appear at the gum — the metal margin. A noticeable layer of tissue is removed for the crown: the framework needs space. If the tooth is already treated and weakened, this is not always a drawback. Metal-ceramic is more often placed on posterior teeth, where strength matters more than ideal aesthetics. The price of such a crown is usually lower than that of a zirconia crown, but the final cost depends on the clinical picture: the number of teeth, gum condition, and the need for a core build-up or post. The exact figure is given by the dentist after examination.

Features of zirconia

The zirconia framework is made without metal. It is milled from a digital model and then veneered with ceramic or left monolithic. The material is dense but transmits light differently from metal: the crown looks closer to a natural tooth. The thin wall allows less tissue to be removed — sometimes this is the deciding factor for anterior teeth. Zirconia does not produce a dark line at the gum and less often causes a reaction to metal. However, it is more expensive, and the veneering on it can chip in rare cases. How much a zirconia crown costs is a question that cannot be answered in one phrase: the price is determined by the design, the number of units, and the technician's work. Neither material is eternal: service life depends on hygiene, bite, and load. The dentist decides — based on X-rays and the condition of the oral cavity.

What is considered for anterior and posterior teeth

Comparison by several characteristics

A crown does not treat the tooth underneath

A crown covers the tooth and takes on the chewing load. It does not remove the reason the tooth was destroyed. If an inflamed nerve or deep decay remains underneath, it will not go away. Over time it will make itself known: pain, swelling, a fistula. That is why before prosthetics the tooth is examined, an X-ray is taken, and a decision is made whether it can be saved. Sometimes the canals are treated first, and only then are impressions taken. It also happens that the tooth is destroyed below the gum level and cannot be restored. Then a crown will not help, and extraction is discussed. A crown is a restoration, not a treatment. It restores form and function, but does not replace therapy. If the doctor suggests placing it right away, without diagnostics, that is a reason to ask questions. The X-ray and examination show what is happening inside. The whole plan depends on that.

Service life depends on several conditions

There is no single number. Many things affect how long a crown will last. Material: porcelain-fused-to-metal and zirconia have different resistance to load and to chipping. How many teeth are missing next to it also matters, because the load is distributed differently. Habits: if a person cracks nuts, opens bottles with their teeth, the crown may not hold up. Nighttime clenching and grinding wear down both natural teeth and restorations. Hygiene: plaque at the crown margin softens the gum and undermines the support. The quality of preparation and the precision of the fit also matter — a gap or an overload creates constant pressure on the tissues. A separate point should be made about the teeth that support the crown: if there is inflammation under them, the structure loses its support. So service life is not a property of the crown, but the result of several factors. The doctor cannot give an exact number of years in advance.

The Doctor Makes the Decision

The choice between porcelain-fused-to-metal, zirconia, and other options does not come down to price or fashion. The doctor looks at the clinical picture. How many teeth are missing, how the neighboring teeth are positioned, what the height of the crown portion is, how the jaws close. Esthetics matter too: a front tooth and a chewing tooth are different tasks. Metal allergy, bruxism, gum disease — all of this changes the choice. The patient states their preferences, and that is right. But the final decision is up to the specialist, because they see what is not visible from the outside. Sometimes two options look equally attractive, but one of them will cause fewer problems in a specific situation. Sometimes cheaper does not mean worse, and more expensive does not mean better. It depends on the case. Risks and alternatives should be discussed before treatment begins, not after.

Care and check-ups are important

A crown does not deteriorate from food by itself. Problems begin where plaque accumulates: at the margin, between the teeth, under the gum. Brushing is needed twice a day, and an interdental brush or dental floss helps in places the toothbrush cannot reach. An oral irrigator does not replace floss, but complements it. If the gum bleeds or there is an odor, that is not normal, but a signal. Dental check-ups are needed regularly, even when nothing hurts. The doctor checks the marginal fit, the bite, and the condition of the supporting teeth. A small chip or a loose crown is easier to fix right away than to wait until the structure becomes mobile. Professional hygiene removes hard plaque that cannot be removed at home. Visit intervals are chosen based on the condition of the oral cavity, not on one schedule for everyone. This is part of care, not a separate procedure.
