Fixed dental prostheses in Almaty: types, prices, installation

How the prosthesis is held in the mouth

Fixation is the main thing that distinguishes the two groups of restorations. A fixed prosthesis rests on pre-prepared teeth or on titanium screws implanted in the bone. The patient does not remove it themselves: to take off a crown or bridge, the doctor cuts the cement or unscrews the screw. A removable one works differently. It rests on the gums and is held by clasps onto adjacent teeth, or on an edentulous jaw by suction to the mucosa. Hence the difference in sensations. A fixed restoration transfers chewing load to the abutment, not to the gums, so it does not shift during speech and eating. A removable one presses on soft tissues, and food debris accumulates between the base and the palate. Care also differs. The first is cleaned with a brush and interdental brush in the mouth, like natural teeth. The second is taken out, washed separately, and left in a solution overnight. However, a fixed option is not always possible: healthy abutments or sufficient bone volume for implants are needed. If this is not available, the doctor considers a removable restoration or another plan. The clinical picture determines the choice.

Key differences from removable options

Types of fixation: on teeth and on implants

Who is suitable for this method of prosthetics

A fixed prosthesis is considered when there is something to support it. A bridge requires strong teeth adjacent to the gap. For an implant-supported structure, sufficient bone volume and no contraindications to surgery are needed. A single crown is suitable if the tooth is destroyed but the root is preserved. There are cases when a fixed option is not suitable. For example, with mobility of the abutment teeth, with a significant bone defect without the possibility of augmentation, with certain systemic diseases in the acute stage. Then the doctor suggests a removable structure — it is simpler and does not require surgery. Sometimes the decision is made in stages: first removable, then implantation. The cost of fixed dental prostheses depends on the number of abutments, the material, and the method of fixation, so the plan and estimate are drawn up after examination and imaging. The price is determined individually, and it is impossible to name a sum before diagnosis. In any case, the choice between the two groups of structures is a compromise between load, aesthetics, care, and the condition of the oral cavity. The doctor decides together with the patient.

What a crown covers

A crown fits over a single tooth. This may be a tooth with the pulp removed, with a large filling, cracked or severely destroyed — one where the filling no longer holds. The doctor grinds the stump around its circumference, takes an impression or scans it with an intraoral scanner, and the cap is made from this impression. The crown covers the tooth entirely, from the gum to the chewing surface, and takes on the chewing load. The neighboring teeth are not touched. If the adjacent tooth is healthy, it is not ground down or included in the work. Hence the main difference from a bridge: the scope of intervention is limited to one tooth. The cost of such a structure is calculated per unit, not by the number of abutments. The doctor decides whether a crown is sufficient or the stump is too weak and a different approach is needed. Sometimes an inlay or post is placed under the crown, sometimes the tooth has to be extracted — this depends on the clinical picture.

When a bridge is placed

A bridge is needed when one or several teeth in a row are already missing, and the teeth adjacent to the gap can be used as abutments. The abutments are ground down, crowns are placed on them, and between them is the pontic — the body of the bridge, which hangs over the gum and restores the chewing row. The structure is held not by implants but by the patient's own teeth, and the load is distributed among them. Therefore, the abutments must be strong: if the adjacent tooth is itself destroyed, it may not withstand the load. The bridge closes the gap but does not touch the gum in the area of the pontic — access for hygiene is needed there. The longer the gap, the higher the load on the outermost abutments, and this limits its use. The cost of such a structure depends on the number of units: two abutments and the pontic are counted separately. When several teeth in a row are missing, the doctor decides based on imaging: sometimes a bridge is possible, sometimes not.

Adhesive bridge and its features

What the structure is supported by

The supports are screwed into the bone, left to heal, and then a framework with crowns is fixed onto them. The load is transferred through the implant into the jaw, and the gums do not serve as a support. Therefore, this structure does not rest on the mucosa, does not cover the palate, and does not shift during chewing. The number of supports is determined from a CT scan: the volume of bone tissue, its density, the position of the mandibular canal, and the maxillary sinuses are assessed. Where there is insufficient bone, additional procedures are performed — bone grafting or sinus lift — and this changes the plan. The structure can be conditionally removable or fixed, with the difference being in how it is attached to the supports. A prosthesis for a single tooth is a crown on a separate implant, not a bridge supported by adjacent teeth. This option keeps healthy teeth untouched; they are not ground down for crowns. Healing times vary from person to person and depend on the clinical picture. The doctor decides after examination and imaging.

Conditionally removable and bar-supported structures

What influences the choice in favor of implants

The decision depends on the condition of the bone, the number of remaining teeth, and overall health. Chronic diseases in an acute phase, poor blood sugar control, and smoking all shift the choice, sometimes toward a removable option. Hygiene is also considered: if a person is not prepared to clean the structure every day, implants are at risk. Motivation also matters: some people cannot tolerate a removable denture, while for others it rubs and interferes with speech. In such cases, the supports provide rigid fixation without relying on the gums. Fixed full-arch dental prostheses, the price of which is calculated by the number of supports and the type of structure, are planned in advance. The final decision is made by the doctor after a CT scan, examination, and a discussion about what the patient is willing to do at home.

What a metal-ceramic crown consists of

The framework is cast from an alloy — cobalt-chromium, nickel-chromium, sometimes noble metals. A ceramic mass is applied layer by layer onto the framework and fired in a furnace. The metal holds its shape and distributes the chewing load, while the ceramic provides color and gloss. Because of the opaque base, light does not pass through the crown, so it looks denser than the adjacent teeth. Over time, a thin dark line may appear along the gum margin — the metal shows through. The technique has been refined over decades, so such structures are still widely used today. With proper hygiene and no overload, the crown lasts for years, but the exact lifespan cannot be predicted — it depends on the clinical picture. Preparation also differs: for metal-ceramic, the tooth is ground down more noticeably than for all-ceramic restorations, because space must be made for both the framework and the veneering layer. The technician selects the thickness of the ceramic so that it covers the metal and does not interfere with the closure of the teeth. The finished crown is checked on a model and then cemented.

How a zirconia crown is made

Zirconia is a ceramic without metal. The blank is milled on a machine according to a digital model built after scanning the tooth stump. The gap between the crown and the shoulder is minimal. The material is opaque by itself, but modern blocks are multi-layered: color and translucency vary by height, so the crown is closer to a natural tooth. There is no metal — therefore, there is no dark line at the gum. Zirconia is strong, and it is used both on posterior teeth and in bridge structures. The surface is smooth, and plaque accumulates less than on metal-ceramic with its ledge. There are also limitations: the material is more expensive to produce, and in cases of severe wear of the opposing teeth, the doctor decides. Careful hygiene is required, otherwise gum inflammation can ruin the result.

Comparison by several criteria

What the doctor considers when selecting a material

The first factor is the area. In the front, aesthetics matter more, and zirconia wins there. On the chewing teeth, the load is higher, and metal-ceramic performs just as well. The second is the condition of the gum: a thin biotype and a tendency to recession make the dark edge noticeable, so a metal-free restoration is chosen. The third is the height of the crown and the bite: with severe wear or bruxism, the material is selected especially carefully. The fourth is the length of the bridge: the longer it is, the more important the rigidity of the framework. The fifth is metal allergy, although it is rare. The sixth is the budget, but that is already a matter of planning, not medicine. Sometimes the decision changes along the way: after preparation, it becomes clear whether there is enough space for the ceramic. The doctor weighs all of this and suggests an option, and the final choice is made by the patient together with the doctor. There is no universal answer as to what is better — it depends on the clinical picture.

Home hygiene: brush, floss, interdental brush

Irrigator and additional products

An irrigator washes away plaque and food debris from under the pontic of the bridge and around the crowns, where a brush cannot reach. The stream is directed at an angle to the gum margin, starting with minimal pressure so as not to injure the gum. If there is a gap under the restoration, the setting is chosen so that water comes out the other side, carrying away debris. Mouthwashes with chlorhexidine are used in courses, not continuously: long-term use changes the color of the tongue and teeth. Single-tufted and interdental brushes complement the irrigator, not replace it. If there is a tendency to gum inflammation, the doctor may recommend a medicated toothpaste with an anti-inflammatory component. A bridge requires the same care as a single crown: the only difference is the number of places that need to be reached with a brush and floss. Prosthetic treatment does not cancel home procedures — on the contrary, it makes them mandatory every day.

What to do for gum inflammation or a chip

If the gum around the crown is red, bleeds when brushing, or aches, you should not wait for it to go away on its own. First, step up hygiene: a soft brush, an irrigator with warm water, rinsing with a herbal infusion. If the gum does not settle within a few days, an examination is needed: the cause may be an overhanging crown margin, cement that got under the gum, or a buildup of plaque. A chip in the ceramic or a chip in the veneering is a reason to come to the clinic, not to glue it back on yourself. Sharp edges are temporarily covered with orthodontic wax from a first-aid kit so as not to cut the tongue. A loose crown is removed and re-cemented: you cannot walk around with it, as saliva and food get underneath. Implant mobility, pain when biting, swelling of the gum — these are conditions for which a visit should not be postponed. What exactly to do in each case is decided by the doctor after an examination and an X-ray.

Why hygiene affects service life

A prosthesis is held not only by cement or screws. Its stability depends on the tissues around it: the gum and bone that bear the load. Plaque at the crown margin causes gum inflammation and, over time, bone loss. Then even a correctly made restoration loses support and becomes loose. Around implants, a soft-tissue barrier forms at the neck, and plaque accumulation in this area undermines it from within. Flossing under the pontic of the bridge keeps food from lingering and irritating the mucosa. An irrigator washes away what remains after brushing. Regular checkups make it possible to notice a problem before it becomes visible to the eye. The service life of a prosthesis depends on the clinical picture, hygiene, and load, not on a single material. No one can say in advance exactly how long a restoration will last: the doctor determines this based on the condition of the tissues and care.

Diagnostics before work

The process begins with diagnostics. The doctor assesses the condition of the abutment teeth, the position of the gingival margin, and the bone density in the implant area. Cone beam computed tomography provides a three-dimensional image of the jaw: it shows whether there is enough bone around the root, whether there are hidden foci of inflammation, and how the mandibular canal and maxillary sinuses run. A microscope with 25× magnification helps prepare the tooth stump for the crown carefully, without excessive grinding. Next, an impression is taken. An intraoral scanner builds a digital model instead of a tray impression — it is sent straight to the laboratory, and the technician works with a file rather than with plaster. The entire subsequent chain depends on how complete and accurate this file is. The cost of a fixed prosthesis is largely determined by this stage: a digital protocol requires fewer remakes at the try-in appointment.

Scanners and milling machines

Ceramic firing furnaces

Ceramic is applied to the framework in layers and fired in a furnace. Each layer has its own regimen: temperature, heating rate, and holding time. This determines the color, translucency, and strength of the coating. First, an opaque layer is applied; it masks the metal or zirconia. Then dentin and enamel layers, with intermediate firings between them. The furnace maintains temperature to within a degree, otherwise the ceramic will foam or lose its gloss. There is another approach: the ceramic is milled from a ready-made block and then sintered in a high-temperature furnace. This method produces a uniform structure without manual layering. Which option is applicable is decided by the technician together with the doctor — it depends on the clinical picture and on which area is being restored. Cooling is monitored separately: too rapid a temperature change leads to internal stresses, and then a crack may develop in the ceramic. That is why the furnace regimen is selected for the specific material rather than using a single template for all cases.

How equipment relates to fit accuracy

The crown seats on the stump without a gap if the digital model accurately reproduces the tooth relief. The scanner captures it without the deformation that impression material produces as it sets. The milling machine maintains the specified wall thickness — a thin wall crumbles, a thick one presses on the gum. The furnace does not overfire the ceramic, and it does not crack during chewing. Each stage is linked to the next: an error in the scan will not be corrected by a precise milling cutter. Fixed prostheses are held on the abutments by the tight fit of the margin, and a gap of fractions of a millimeter already creates a space where plaque can accumulate. That is why the laboratory and the clinic work within a single digital protocol. A laser is used during soft tissue preparation if the gingival contour needs to be adjusted before impression taking. Class B autoclaves sterilize instruments between appointments — this is the hygiene component, without which work with oral tissues is impossible.

The type of restoration is selected individually

The choice between a crown, a bridge, and an implant-supported prosthesis does not come down to price or habit. The doctor looks at the condition of the abutment teeth, bone density, the length of the defect, and how the jaws close. One patient comes with a single missing tooth, another with several missing in a row, and a third with complete tooth loss in the jaw. In each case the logic is different. Sometimes the adjacent teeth are healthy, and there is no desire to touch them for a bridge. Then implantation is discussed. Sometimes it is the opposite: the abutments have already been treated, and a bridge resolves the issue without additional interventions. The patient has the right to know the alternatives, but the decision is made by the doctor after examination and imaging. Cone beam computed tomography shows what cannot be seen with the naked eye: the thickness of the bone wall, the course of the canals, and the condition of the maxillary sinuses. Planning is impossible without this picture. Selecting for a specific case is not a polite formula but a necessity. There is no universal prosthesis that suits everyone.

Material and abutments affect wear

Metal-ceramic and zirconia behave differently. The former is cheaper, but over time a dark line may show at the gum. The latter looks more natural and accumulates less plaque, but it requires more precise processing. What matters more in a specific case — aesthetics, strength, or budget — is decided by the doctor together with the patient. The supports also set the rules. The natural teeth under a bridge must be stable and free of hidden inflammation. An implant does not rest on the neighbors at all; it is embedded in the bone, and therefore its position is planned in advance using a CT scan. The 3Shape intraoral scanner takes a digital impression: it is more accurate than a tray with impression material, and there are fewer remakes at the try-in. A microscope with 25× magnification helps the doctor see the preparation margin and avoid touching anything unnecessary. These devices do not make treatment the same for everyone; they merely reduce the number of errors. The lifespan of the prosthesis depends on how accurately it fits and how well the patient takes care of it.

Hygiene extends the lifespan

A fixed restoration is not removed at night, and this changes habits. Plaque accumulates at the edge of the crown and between the pontic and the gum. If it is not removed, the gum becomes inflamed, odor appears, and the support under the bridge may lose stability. A regular brush does not always reach these areas. Interdental brushes, a single-tuft brush, dental floss, or Super Floss are needed — whatever passes under the pontic. An irrigator helps wash out food debris, but it does not replace mechanical cleaning. Toothpaste with abrasives is not suitable for polished ceramic: it leaves micro-scratches, and plaque clings more strongly. In the clinic, a laser is used to treat the periodontal pocket if inflammation has already started, but this is treatment, not a replacement for home care. Class B autoclaves sterilize instruments between appointments, and this is a standard, not an advantage. A professional cleaning at the doctor's office every six months removes what cannot be removed at home.

Regular check-ups with the doctor

Even a careful patient cannot see what is happening under the crown. The marginal fit changes imperceptibly, a screw may loosen, and the gum around the implant may show the first signs of inflammation without pain. Therefore, check-ups are needed not when something hurts, but on schedule. The doctor checks the bite, the condition of the supports, the fixation of the restoration, and takes an X-ray if there are doubts. An early finding is usually resolved simply: tighten, clean, replace the gasket. A neglected problem requires removal of the restoration and repeat prosthetics. A CT scanner and a microscope help see what is hidden, but they are used according to indications, not at every visit. The lifespan of the prosthesis depends on the clinical picture and care, not on a single date in the chart. A warranty of up to 5 years applies if the rules are followed: the patient comes for check-ups and does not skip hygiene. This is not a formality, but a condition written into the contract.
