Dental Restoration

Contents:

Dental restoration is a method of restoring teeth using various materials (veneers, inlays, lumineers, crowns), preventing tooth decay. You can hide minor defects (chips, cracks), change the size and shape, or make your teeth snow-white. As a result, they will look like healthy natural teeth.

Aesthetic Dental Restoration

Aesthetic restoration is called a cosmetic one. This complex process allows simulating natural teeth using different materials. They restore their shape, snow-white colour and transparency. Benefits of aesthetic restoration:

  • Complete restoration. Minor defects can be corrected or hidden.
  • Variety of materials. Veneers, inlays, light-cured fillings, lumineers, and crowns are mainly used for restoration. They are selected depending on the problem.
  • No need to grind down the adjacent teeth.
  • Fast restoration. Most often, 1-3 visits are enough for this.
  • Last long. Restored teeth last for 7-10 years. They can be adjusted to extend the service life.

Indications for aesthetic dental restoration:

  • malocclusion;
  • diseases causing tooth decay;
  • congenital dental defects or their abnormal position;
  • whitening of yellow teeth;
  • damage due to dental trauma;
  • cracked teeth treatment.

The restoration is performed if a tooth is chipped; then, it requires filling replacement and edges alignment.

Types of Tooth Restoration

Types

Features, method’s advantages

DirectIt involves the application of light-curable materials (photopolymers). A dentist-therapist performs the restoration. The restoration is carried out in several stages, in a dental office in one session.

IndirectThis method is used to correct tooth length, inclination and shape, and to close gaps. In addition, indirect restoration helps restore teeth with severe decay, renew chewing function, and a beautiful smile.
An orthodontist and a dental technician carry out the restoration. This method requires a laboratory. First, a specialist makes an impression of the tooth and then a tab using special cement.


Restoration types:


Veneers. They help to hide chips, cracks, minor defects, and incorrect inclination. But it requires minor teeth grinding.


Inlays / onlays. They are placed in the decayed part of the tooth if it is impossible to place a conventional filling. Ceramic inlays perfectly imitate a natural tooth. They are used to restore anterior teeth.


Lumineers. These shells cover stains, teeth gaps, cracks and enamel discolouration. Unlike inlays, no grinding of tooth tissue is required.


Crowns. They are suitable for the restoration of severely decayed teeth in case other options cannot be placed. Crowns can be metal, ceramic, or a combination of both. But a tooth grinding is required.

The material selection depends on the problem. The restoration usually requires more than one visit to a dentist.

 Relative contraindications – bruxism, permanent wear due to malocclusion, cavities. However, the restoration can be carried out after the appropriate treatment.

Aesthetic Restoration of Anterior Teeth

The direct restoration method is used for teeth surface contouring, eliminating gaps, restoring teeth shape and colour. The doctor removes minor defects within 1-1.5 hours without a special laboratory. This is the main advantage of the method. A doctor can restore up to six teeth in one visit.

Restoration Process

Type

Stages

DirectPreparatory stage. The surface is cleaned and polished with special pastes and nylon brushes. A composite material is selected. Anaesthetic is administered.Tooth preparation. The areas affected by decay are drilled out. Old fillings are removed.The tooth is isolated from moisture as it negatively affects the composite materials. Moisture is removed with a rubber dam with cotton rolls.Modelling. The required shape is chosen, an impression is created. Photopolymer materials are used for modelling. It is applied in layers to make the tooth look natural.Final stage. It involves final modelling, grinding and polishing.

IndirectFirst, the teeth are assessed, the purpose of the restoration is specified, and an impression is made if necessary. Then a doctor:selects the colour of a veneer or crown;grinds down a tooth;takes an impression;gets a temporary veneer made, tries it on, corrects the shape;gets permanent prostheses made in the laboratory.The final stage involves their attachment using a particular compound.

 Aesthetic restoration is aimed at improving the appearance of the teeth. Moreover, they have the same colour as natural ones.

Restoration of Anterior Teeth

The restoration of anterior teeth is the restoration of the upper and lower jaw (central, lateral and canines along a smile line). Therefore, the materials for them are chosen more carefully in terms of transparency and colour. In most cases, light-curable fillings, veneers and crowns are used.

The materials should resist shrinkage, be tissue-compatible, saliva-resistant and aesthetically pleasing. Additionally, dental tints are used. They help to recreate the minor details and give your teeth a natural colour. For children, zirconium dioxide or metal crowns are used.

An indication for the restoration of anterior teeth is partial/complete decay, chips, abnormal shape or other defects. The restoration can be performed in two ways. The direct method allows correcting defects in one visit. For an indirect one, you need to visit the dentist several times. The restoration procedure is standard.

Restoration is performed using a silicone impression, which is formed before the preparation of the tooth. The procedure is similar to the indirect method. However, silicone is used as a pattern for the previous tooth shape. This method is suitable if the integrity of the enamel is not compromised and there is no decay process causing cavities.

There are several contraindications for the restoration of anterior teeth:

  • infectious process in the root (restoration is possible only after treatment);
  • excessive tooth mobility;
  • extensive destruction of the coronal part;
  • root crack or fracture.

Some contraindications are relative; the restoration is performed after the relevant treatment.

How Long Do Restorations Last?

The service life of dental restorations depends on the material type. On average, it is:

  • 10-20 years for fillings;
  • 10-15 years for lumineers;
  • 15-20 years for veneers;
  • 15-25 years for crowns, onlays.

If you follow all the doctor’s recommendations, practice good oral hygiene, quit smoking, then the service life of the restored teeth will not be reduced.

Before restoration, dental examination, cleaning and treatment are performed. If this is not done, teeth can decay under masking composites. Then it will require opening and proper treatment. Subsequent restoration can be more expensive.
