Implant-supported bridge prosthetics

When it comes to the need to replace three or more teeth that are next to each other, there are several different options available. One of the most effective is implant-supported bridges. This solution has a number of advantages that favorably distinguish it from its competitors. The use of fixed structures of this format allows you to quickly restore the maxillofacial apparatus and achieve the greatest both aesthetic appeal and full functional recovery.

What is an implant-supported denture?

An implant-supported dental bridge, unlike adhesive dentures or other removable bridges, has one distinctive feature. Healthy teeth are not affected in any way. Instead, special dental implants are used as a support, which are implanted into the jaw in the place where teeth are missing

This makes it possible to cover a larger number of missing teeth, as well as to ensure that the living teeth next to the missing teeth remain healthy, as their integrity is not compromise…

How crowns are removed

Reading time ~ 2 min. Number of readings: 96214

Crowns and bridges are non-removable prosthetic structures. Before use, the patient needs to learn about the procedure.

When are crowns removed?

So, first of all, let's understand when the removal of crowns may be necessary:

Uncementation. When chewing, the cement under the crown partially disintegrates and the patient feels the movement. The loosened structure is removed, the cement residue is removed, and the crown is reinstalled. Painful sensations under the prosthesis. Theoretically, procedures can be carried out through the holes, which after treatment are filled. In fact, not always the method is effective and allows you to get to the lesion Repeated prosthetics. If the tooth next to the onlay is destroyed, it makes sense not to install a separate denture, but to fill the gaps in the tooth row with a single bridge. The onlay is removed, and the patient…

Ceramic or composite veneers – which is better to choose

Reading time ~ 5 min Number of readings: 7712

To understand which veneers to choose, ceramic or composite, let's take a closer look at what tooth onlays are and what their features are. Veneers are thin plates made of ceramic (sometimes zirconia) or composite material, which are fixed to the front side of the teeth. Such microprostheses are used to correct aesthetic imperfections of the dentoalveolar apparatus, additional protection of enamel. Made from impressions, the onlays imitate the natural shade of the tooth row and do not stand out from it.

Veneering aligns the tooth row, hides defects (uneven teeth, large interdental gaps, cracks or chips of the crown shell), simplifies oral hygiene, serves as an effective means of preventing periodontal disease.

Types of veneers

Microprostheses are divided into composite and porcelain. Composite are divided into:

They are manufactured in the p…

Why patients are afraid of dentures

Removable and fixed dental structures are the two pillars on which prosthetic dentistry stands. No two clinical situations are alike, and there is no one-size-fits-all method of tooth reconstruction. When a patient comes to see a prosthodontist, he or she expects to get a solution to the problem. And the doctor offers at least 5-6 ways to replace lost teeth. But:

some patients are intimidated by the grinding of teeth, others are intimidated by the possibility of wearing a removable jaw, others are intimidated by the cost of orthopedic treatment, and some of the above.

We would like to add that many are afraid of pain, which has not been experienced by visitors to clinics for a long time. At the doctor's disposal is a choice of local anesthetic drugs for children, people suffering from hypertension, allergic people. In dental centers, sedation is used to reduce anxiety and enhance the effect of anesthetics. Sometimes sedation is made deep, and the patient falls…

Preparation for prosthetics

Sooner or later we all have to use the services of a prosthodontist. A crown on a decayed tooth, a bridge, a bracket or plate prosthesis, veneers - whatever method we use, the success of treatment depends largely on the preparation for prosthetics.

Specific measures may vary depending on the type of work, but there are general principles. If they are not followed, it may be a reason to change dentistry. A qualified prosthodontist is interested in the result of his labor. Such a doctor understands that there are no trifles.

Psychological preparation

Most people are afraid of going to the dentist. A patient who is stiff, shaking from fear does not go well to a conversation, it is difficult to interact with him. The work of the prosthodontist begins long before the fitting of the prosthesis. The first thing to do is to establish emotional contact. If the doctor is friendly and attentive, he is trustworthy. The patient will be more open to discussin…

Although prosthodontics as a science was formed not so long ago, people have been practicing dentures since antiquity. Animal bones, semi-precious stones, hard wood - what only ancient physicians did not use as a material of prostheses. But the methods of fastening were rather monotonous - with the help of gold, rarely silver, wire.

What are dentures made of now? The composition for prosthetics is selected for a specific clinical case, taking into account the patient's wishes, indications and contraindications.

Basic requirements to the material for dentures

Although a wide variety of materials are used in prosthetics, all of them must meet certain requirements: to be durable, functional and attractive in appearance. This is why gold crowns and iron …

Denture relining: correction methods

Reading time ~ 5 min Number of readings: 30413

The basis of comfortable use of removable orthopedic systems - a secure fit to the jaw. But gradually the fixation of the structure weakens, functionality decreases, there is discomfort when eating, talking. Rebasing of the prosthesis (partial, full) - involves the elimination of inaccuracies, prevention of damage to the base of the structure, restoration of accurate contact with the gums, supporting dental units. Depending on the clinical case, such a procedure is carried out in the office of a dentist or in the laboratory.

When relocation of the prosthesis is necessary

After fixation of the new prosthetic system, after the first 1-3 months of wear, relining of the denture is necessary to correct the accuracy of its fit to the mucosa. Since the teeth have been missing for some time, the jaw joint has reorganized. After the prosthetic structure is install…

Fixation of crowns: fixation methods and materials

How important is tooth crown retention and what types of retention are used?

In modern dentistry, preserving natural teeth is considered the most important task. For this purpose, various therapeutic and even surgical treatment methods are used. The placement of artificial crowns can be an independent method, for example, if there is pathological abrasion of enamel or part of the treatment. This occurs during endodontic intervention. The pulp (nerve) is removed from the tooth, the tooth becomes brittle, and a crown is used to protect the tooth from decay.

Indications

Indications for restoration:

Significant destruction of the crown portion; placement of bridges; pathologic erasure of enamel; depulpation; trauma.

Crowns are made of metal, ceramic and metal-ceramic. Porcelain and plastic crowns are practically not used due to fragility. Modern materials are characterized by special strength and wear resistance. T…

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

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…
