Metal-ceramic crown restoration

June 5, 2023 Reading time ~ 5 min Number of reads: 11853

Metal-ceramic crowns are considered one of the most durable restorations. They consist of 2 layers: a metal base and a ceramic veneer. The metal perfectly withstands even high chewing loads, while the ceramic gives the structure a natural look.

Unfortunately, ceramics are not as strong as dental alloys, and chipping of the top layer in crowns occasionally occurs.

Causes:

Violation of fabrication technology; Improper (overvalued) occlusion; Change in bite; Strong mechanical impact; Indications for repair

Repair of a chipped crown is only possible if the problem is located in the ceramic layer. In these cases, restoration is possible even with large fragments. But if the metal part is affected, it is impossible to restore the old structure, it can only be replaced.

Therefore, dentists urge to treat dentures with care, their replacem…

Adhesive tooth restoration

September 4, 2023 Reading time ~ 5 min Number of reads: 5972

Adhesion is a special, molecular bond between the surfaces of two different materials. It is the advent of adhesive systems in dentistry that has made it possible to restore teeth with methods that combine efficiency and aesthetics.

As a result of the use of adhesive compositions, a hybrid layer is formed which, due to micromechanical and chemical bonds, provides a strong bond.

Direct adhesive tooth restoration

Dental fillings, build-ups, and artistic restorations are performed using the direct method. This means that the dentist restores the tooth directly in the patient's mouth, without taking impressions.

Indications for the direct method are restorations of:

Cavities; Cavities destroy hard tissue, creatingcavities of varying sizes. They are filled with filling material using adhesion. Non-carious lesions of enamel; Technology…

Causes and symptoms of dental disease

October 18, 2023 Reading time ~ 4 min Number of reads: 1707

Dental diseases are a group of pathologies affecting the enamel and internal structure of the dental unit, the mucous membranes of the oral cavity, gums, chewing muscles and bones of the jaw.

Most dental diseases are infectious in nature and develop one after another in the absence of necessary treatment. Despite the opinion that such pathologies are considered not dangerous for people because of the risk of developing serious consequences for the body, this is not true. Consequences with improper treatment or lack thereof, can be very serious, up to lethal outcome.

Any disease is easier to prevent than to treat, so it is important to have an idea of the causes and symptoms of dental diseases in order to identify them in time and avoid complications.

Causes of dental disease in humans

Diseases of the teeth and gums can appear both due to the…

Why shouldn’t you put off going to the dentist?

November 15, 2023 Reading time ~ 3 min Number of reads: 1354

We should not put off visiting the dentist because teeth are a very important organ of our body. If we don't keep an eye on their health, we can face many problems. And this is not only directly related to the dento-mandibular system, but also to the work of some organs of the body, as well as to our psychological state.

Why should not delay a visit to the dentist?

If you do not treat your teeth now, it will cost much more in the future. So, by addressing the problem today, you save money in the long run.

A simple example. Untreated caries turns into pulpitis, the price for endodontic manipulations is higher. Missed this stage - the peri-dental tissues are affected, up to catastrophic destruction of the crown, infection of the root, loosening of the unit and, as a consequence, extraction.

To delay dental treatment is to increase the ris…

Implant or bridge – which is better for missing teeth?

Bridges and dental implants are used to replace missing teeth. With a bridge, only the outer, crown part is restored. An implant is an artificial root made of titanium, which is integrated into the bone tissue and takes over the functions of the natural tooth root. All things being equal, a classic bridge is not able to compete with implants. Although implant placement is a physiologic technology, the bridge prosthetics supported by your own teeth does not lose ground.

What is a dental bridge

A dental bridge is a fixed prosthetic structure consisting of several artificial crowns. It allows you to restore a segment of missing consecutive tooth units from 1 to 3. Two supports are required for attachment, which are your own teeth. That is why bridges are not used when the farthest units are lost (end defect).

The classic bridge is a framework in the form of several crowns made of metal or precious alloys, covered with a layer of ceramic …

Dental implant or denture – which is better to choose

The loss of even one tooth is accompanied by changes in the functionality of the entire row. Neighboring teeth are distorted, shifted to the side of the missing tooth. Bone loss begins in the empty area. There is no need to talk about the violation of chewing function and psychological discomfort. Implantation and classical prosthetics will help to restore the smile in this case. But dental implantation completely solves the problem of functionality and aesthetics of the tooth row. It is a physiological, durable method of prosthetics.

Methods of restoration of missing teeth

For the installation of any prosthetic structure, a support is necessary. Removable prostheses can be fixed directly to the gums, while fixed prostheses are supported by your own teeth or implants.

Removable prosthetics

Removable structures based on nylon or acrylic (full plate prosthesis) are fixed in the mouth by suction to the gums. They are indicated for comple…

An alternative to dental implants

August 29, 2024 Reading time ~ 7 min Number of reads: 99004

Patients are looking for an alternative to implantation because of financial or clinical limitations to implantation of artificial roots. Removable prostheses (bra, flexible, acrylic) and fixed products made of metal-ceramic, all-ceramic, zirconium (dental bridges) are able to replace the implants incompletely. Rarely missing units are replaced by displacing the neighboring ones with braces. Implantation is the preferred option: it guarantees an aesthetic, long-lasting and reliable result, with safety for the neighboring units and benefits for the jawbone.

When an alternative to dental implants may be necessary

Implantation is not organized for everyone. Contraindications to surgery are:

Psychiatric pathologies; immunodeficiency conditions; cancer; decompensated diabetes mellitus; rheumatism; blood clotting problems; dis…

Dental implants in HIV infection

Acquired immunodeficiency syndrome (AIDS) is the last stage of HIV infection. The body's ability to resist infections and diseases is rapidly declining, which affects organs and systems. Until recently, implantation in HIV was considered impossible. The emergence of one-stage minimally invasive techniques has made it possible to implant implants in people with severe chronic pathologies, including HIV and AIDS. Even patients diagnosed with immunodeficiency or hepatitis can be successfully implanted with the RUTT implant.

Whether implants can be used with HIV

The human immunodeficiency virus (HIV) gradually destroys the immune system, using its resources to replicate new viral particles. At a certain point, the body's resistance decreases to a critical point. An HIV-infected patient develops severe diseases that are rare in people with normal immunity. These are called opportunistic or AIDS-associated diseases.

Implantation is a surgical…

Dental implantation in hepatitis

Hepatitis is an inflammatory pathology of the liver. When the disease develops, increased bleeding of wounds is observed against the background of protein deficiency. The prolonged healing period limits the number of surgical interventions: implants implantation in patients with hepatitis is longer and more difficult. On the eve of implantation of implants in a patient with hepatitis it is important to make a thorough preparation: examination by an implantologist, medical examination, tests. Permission for implantation is given by the therapist.

Is it possible to implant teeth with hepatitis?

Hepatitis is not an absolute contraindication to implantation. The operation is done if a number of conditions are met:

hepatitis is diagnosed in remission; there are no manifestations of pathology; blood parameters are not disturbed; the patient undergoes regular preventive examinations with a specialized doctor and follows therapeutic principle…

Can dental implants be placed with diabetes mellitus

November 6, 2023 Reading time ~ 6 min Number of reads: 7981

Diabetes mellitus is a pathology of the endocrine system, accompanied by insulin insufficiency and failure of carbohydrate metabolism in the body. High blood glucose concentration in diabetes worsens wound healing. This is a factor that previously prevented implantation in diabetics.

The impact of the disease on the condition of the teeth

With increasing blood sugar levels, the negative effect of glucose on the body increases - conditions for the development of a number of oral diseases appear:

Hyposalivation (saliva deficiency). Dry mouth destroys the enamel layer - caries develops, pathogenic microflora spreads in the oral cavity. At high rates, acetone is released, increasing the demineralization of enamel. Inflammation of the gums. The root system of the tooth is destroyed. Wounds take a long time to heal, with the attachment of inf…
