What kind of filling material is better?

How to eliminate tooth decay? The best option is to use modern filling materials. In dentistry, various groups of excipients are used for this purpose. The choice of a particular composition depends on many factors: its properties, safety for the organism, and cost. The following brief overview of the materials for dental treatment will help orient the patient.

Filling material is divided into the following types:

1. Silver amalgam. This material actually lost its former popularity, it is morally obsolete, recently it is almost not used. It includes mercury, whose vapors are highly toxic. Widespread use of silver amalgam in dentistry was due to a number of advantages: strength, durability, high antibacterial performance, low cost. Essential disadvantages: low adhesion, for resurfacing a seal, a repeated visit to the doctor, unaesthetic appearance, can darken and split the tooth tissue, toxicity, loose marginal fit.

2. Stomatological cements. Widely used about twenty years ago. The best filling material from this group, which is still used today, is glass ionomer cement. Composition: silicon, aluminum, fluorine. Mix with distilled water or polyacrylic acid (50% solution).

Pluses:

- quickly hardens - within a few minutes;

- releases fluorine, promotes regeneration of tooth tissues - consists of a mixture of fluoroaluminosilicate and polyacrylic acid (this filling serves as prevention of caries recurrence, therefore glass ionomer cement is indispensable for the treatment of milk teeth);

- moisture resistance - can be used as an insulating pad that protects tooth tissues from destructive aggressive effects;

- harmlessness - does not irritate the pulp;

- high adhesion - able to bind calcium with hard dental tissues.

3. Composite filling materials. Most in demand lately. The composite consists of an organic matrix (synthetic resin) and an inorganic filler (quartz powder). To treat chewing teeth, a material with larger quartz particles is used to provide the necessary strength for a long time.

Advantages of composites:

- resistance to abrasion;

- safety for health;

- high strength;

- ease of use;

- Perfect polishing;

- the possibility of using for successful restoration of anterior teeth;

- high aesthetic properties - filling material allows maximum imitation of natural color, texture, transparency, i.e. Gives a dry gloss effect;

- a wide range of.

Possible complications:

- sensitivity - occurs when the technique of treatment is violated, a large portion of the material is laid;

- rapid erasure, loss, if improperly matched filling material, also the composite can not be used to treat patients with increased erasability of tooth enamel;

- tooth decay, cleavage of its walls - do not use composite material to restore the crown of the tooth, destroyed by more than 50%.

Thus, the choice of a specific composition of the seal - cement, metal or polymer - better to trust the dentist. He will assess the condition of the teeth and suggest the best option for a particular patient.
