Attachment of removable dentures during prolonged wear with intense loads loses functionality.
Gradual weakening of locks or hooks requires relining of the removable denture. It is not difficult to determine that you need to contact a specialist for help. During a conversation or eating, gradually progressive discomfort begins to appear. Relining the removable denture will ensure a tight fit of the structure and will completely normalize the bite. By postponing a visit to the orthodontist, people expose the oral mucosa to danger and the likelihood of injury increases.

Symptoms that should not delay a visit to the dentist

You should make an appointment with an orthodontist if:

• changes in the alveolar process of the upper jaw appear;
• the prosthesis has received damage that is not visible to a specialist, or significant flaws have appeared after prolonged wear;
• the height of the lower third of the face has undergone atypical changes. At the same time, the minimum initial deviations rapidly increase;
• The relief of the oral mucosa changes dramatically during prosthetics or after prolonged use of a stationary prosthesis.

What it is

Relining is the correction of an insert structure to improve the fit of the prosthesis to the gum and restore chewing functions. In addition, the rebased design should ensure the correct bite of the teeth when closing and opening the jaws.

If you neglect this procedure, you can get the following complications:

• breakage of the prosthesis;
• deformation and loss of supporting teeth;
• inflammation of the soft tissues of the oral cavity.

Contraindications

Relining a removable denture is not done if:

• damage to the structure occurred due to a strong impact on a hard object or other mechanical impact that violated the integrity of the system;
• the prosthesis no longer meets the standards necessary for its continued wearing due to loss of integrity;
• there are one or more broken elements;
• anatomical retention is impaired, in which the prosthetic bed is not able to hold the prosthesis;
• The structure is unstable and can fall apart into its component parts at any moment.

The above reasons indicate the futility of relining a removable denture, since urgent production of a new system is required.

Types of relining material

Correction of removable laminar dentures involves the use of the following materials:

1. Hard plastic
   – cold-curing acrylics (Protacryl, Redont), hot-curing acrylates (Ethacryl, Ftorax, etc.), polymethyl methacrylate. Solid base plastics are used for rigid fixation of orthopedic systems or laboratory relocation.
2. Soft composites
   – acrylic, silicone elastomers. It is used if the physical parameters of the orthopedic device are normal, but the patient experiences headaches and discomfort. Typically used for relining mandibular prosthetic structures.
3. Temporary elastics
   (conditioners) – polyvinyl chlorides and silicone base materials are highly elastic and are used for soft relining of dentures in case of systematic inflammation of the gums. Elastic materials are characterized by particular softness and are intended to reduce and uniformly redistribute chewing pressure to sensitive areas of the mucosa. Temporary material should be regularly updated, as it reacts negatively to cleaning agents and is susceptible to the accumulation of bacterial plaque.

The cost of relining an orthopedic system depends on several parameters - the technology used, material, type (clasp, conditionally removable, removable), size of the prosthesis, etc.

The main causes of prosthetic failure

Dentures often break suddenly. There can be many reasons for the breakdown, here is a list of the most common ones.

• The presence of an original design defect during manufacturing.
• Violations of prosthesis installation technology.
• Poor quality prosthesis care.
• Excessive chewing load on the denture.
• Patient injury.
• Falling of the prosthesis onto a hard surface.
• Poor quality material from which the prosthesis is made.
• Structural changes in supporting teeth (looseness, destruction).

Relocation technique

Orthodontists use two main types of denture relining.

1. Clinical . It is limited by the patient’s intolerance to certain synthetic components that cause allergies, or chronic diseases of the oral mucosa.
2. Laboratory . The most secure, reliable, convenient.

Only the attending physician chooses a technique based on the patient’s current condition, associated issues, and clinical picture.

General overview

From a medical point of view, the term “relining a removable denture” is a general term and covers a whole range of manipulations aimed at restoring a tight fit. Such a correction may be required already in the first months after prosthetics - prolonged absence of row elements leads to bone tissue atrophy, and restoration of the load causes its deformation. In this regard, doctors recommend that patients who have undergone surgery visit the clinic at least once a quarter during the first year, eliminating the possibility of developing negative consequences.

Features of the clinical method

1. Complete examination of the oral cavity, checking the integrity of the prosthesis.
2. After analyzing the bite, the size of the marginal area is adjusted. The long one is cut off. Short - extended using quick-hardening plastic substances.
3. A small layer of 1 mm will be removed from the prosthesis. The edge fragment loses polishing.
4. Thorough impregnation of artificial elements with Vaseline.
5. The boundaries of the marginal area are completely treated with a liquid polymer mixture.
6. After the outer layer becomes dull, the prosthesis is put on by the patient. It is necessary to close your jaws tightly and hold in this position for a couple of minutes.
7. The system is then polymerized in special equipment.
8. After ten minutes of treatment, the prosthesis is removed to be adjusted manually. In the finale, he is immersed in hot water.

The advantages of clinical relining of a removable denture include the rapid elimination of existing deficiencies, as well as ideal accuracy. The disadvantages include the high porosity of the material, which reduces the hygiene of the system, and color changes.

Necessity

Violation of fixation leads to constant contact of mucous tissues with the hard surface of the prosthetic structure. As a result - painful sensations, rubbing effect, and a high probability of developing inflammatory processes. This applies not only to classic removable products, but also to replacement systems installed in accordance with the all-on-4 implantation protocol, since integration of implants into the bone leads to active regeneration caused by increased load. A change in bite leads to a change in the position of the prosthesis, which necessitates adjustment.

Relining of removable dentures using the laboratory method

• The work is performed by a technician in a laboratory.
• The degree of wear of the prosthesis, quality of manufacture, and tightness of fit in the mouth are assessed.
• A control impression is made for transmission to the doctor.
• The surface of the prosthesis undergoes special treatment.
• A copy of the impression and the system are lowered into a ditch, after which they are filled with diluted plaster.
• The cast is taken out, and the resulting void is filled with polymerizing plastic.
• The excess is cut off, after which the product is polished.

The main advantages of the laboratory technique include the absence of contact between the mucous membrane and the plastic, a strong connection between the old and new layers, and an excellent aesthetic appearance. The disadvantages include the length of the process. The patient is forced to go without a prosthesis for several days; errors are possible that require additional time to eliminate defects.

Features of relining nylon structures

Patients often wonder whether it is possible to reline nylon dentures. Experts answer that it is possible, but not necessary. Firstly, applying a layer of material to the base leads to its thickening. This may cause the structure to lose elasticity and increase the likelihood of poor fit and discomfort.

The second reason is the increased hygroscopic properties of nylon. During operation, the material became “filled” with microorganisms, the complete removal of which is not possible. As a result, the new material applied during relining will peel off.

On a note! Experts note that the cost of relocating a nylon product can be compared with manufacturing a new one. In addition, it must be taken into account that the service life and quality of the restored structure are significantly reduced.

Frequently asked questions - answers:

Which prosthesis is better to choose - domestic or imported?
Perhaps, from an aesthetic point of view, our products are inferior, but in practice they turned out to be much stronger and more reliable than imported dentures.

Why is the denture, which I have been using for less than a year, constantly getting in the way and falling out? This has already begun to cause psychological discomfort.

The implant was simply not adjusted to the end. We advise you to do a relocation; do not worry, there is nothing painful or scary in this procedure.

Why do I need to reline the prosthesis if nothing bothers me?

Reliable fixation of the prosthesis is an extremely important condition for the full functioning of the entire dental system. And, of course, comfort. Any artificial teeth need to be looked after - cleaned and regularly shown to an orthopedic dentist.

How much does the procedure cost?

The cost of relining dentures consists of several parameters. The final cost is influenced not only by the chosen reconstruction method, but also by the material used, the dimensions of the structure, the type of product (clasp, nylon, conditionally removable, and so on). The region in which this service is provided is of great importance - as a rule, in the central regions of the country, in Moscow, St. Petersburg, cities with a population of over a million, the cost is higher. No less important nuances are the status of the clinic and the qualifications of the specialist. Average prices for reconstruction of removable dental structures range from 3,000 rubles using the clinical method and 6,000 rubles using the laboratory method.

Don't know what type of prosthetics to choose?

On a note! Many clinics include the relining service (not repair, but adjustment to a changing bite) in the cost of a denture. This way you get the design and don’t pay anything for its regular “tuning”. This allows you to significantly save on treatment.

It is also worth paying attention to the fact that within the framework of the warranty (usually 1-2 years), relocation and repairs should be carried out completely free of charge. Be sure to clarify these points when concluding and signing the contract.

My daughter’s denture broke on the eve of her wedding, I was very upset, but Denta-Labor managed to fix it very quickly and efficiently, thank you.

Fitting and application of the finished removable laminar prosthesis

The denture should be easy to put on and stay in the mouth. After receiving the finished product, the doctor checks its fixation using special techniques, and also clarifies the situation, asking the patient to move the lower jaw in different directions. If necessary, additional corrective measures are carried out, which consist of grinding the base in the right place.

Be sure to check the closure of the dentition using carbon paper. If a defect is detected, a small milling cutter is used to selectively grind the teeth, trying to preserve the anatomical shape of the teeth.
