This dental procedure is the retraction of the cervix by reducing the level of the mucous membrane. Due to this, some part of the root is also exposed. Retraction of the gingival margin is very often performed for the manufacture of ceramic veneers or crowns and for obtaining two-layer impressions. CAM technologies scan plaster models, the accuracy of which determines the correct fit of the prosthesis and the patient’s sensations.

This set of procedures is aimed at expanding the furrow in the horizontal and vertical sides. This helps to reduce fluid secretions, prevent or stop bleeding, and reduce injuries in the oral cavity. Gum retraction is performed in such cases:

  • when filling carious cavities;
  • when preparing defects in the teeth;
  • when bleaching.

Means and methods of gum retraction

There are the following methods of gum retraction:

Retraction of the gums with threads and rings

  1. Mechanical. It is the opening of the periodontal pocket (groove) with the help of various tools: knitted rings, caps or cotton threads.
  2. Medication (chemical). In this case, a gum retraction fluid is used, which can be adrenaline and adrenaline-free. Some drugs can cause systemic reactions in the human body.
  3. Surgical. It consists in excision of the free edge of the gums on its inner surface with a coagulation electrosurgical needle.
  4. Combined. This method combines various of the above methods. The most common of these is mechanochemical retraction. In this case, threads impregnated with liquid are used.

Retraction of the gums with threads and rings

When going to the dentist, many patients wonder what is gum retraction with thread (Ultrapak). This procedure involves the use of special items that are inserted under the mucous membrane. This method can cause pain and lasts a long time, there are also a number of restrictions for manipulations.

Before the start of retraction, the dentist conducts an examination of the oral cavity, while constantly monitoring the depth of invasion into the gum. The doctor must remember that the mucous membrane is very vulnerable and sensitive, so the attachment site of the tooth and tissue can be easily damaged. This leads to recession and periodontal disease. This method is not suitable for prosthetics of the entire jaw.

Chemical gum retraction

There are various methods of gum retraction, but only a doctor can determine which one is right for you. He must find out:

  • What is the patient allergic to?
  • How does he tolerate anesthesia?
  • What diseases does he have?

The chemical method (when using drugs based on adrenaline) often provokes side effects such as:

  • increased blood pressure
  • violation of rhythms in the heart;
  • increased heart rate.

If you suffer from cardiovascular diseases (hypertension, ischemia, etc.), then warn your doctor in advance. In this case, he will use medications that do not include adrenaline. Preparations are prepared on the basis of a solution of zinc chloride and tannic acid. Modern medicines, although they are sparing, can disrupt the integrity of the mucous membrane and are not always fully restored.

Means for gum retraction

The most optimal preparations are those prepared on the basis of kaolin and aluminum oxide. They include various hemostatic components and polymers. They come in the form of a gel and paste. Medicines are produced in special cartridges (similar to a syringe), which allow you to accurately apply the product and minimize the risk of damage to the oral cavity.

The gum retraction gel has analgesic and hemostatic properties, and the desired effect can be obtained in 2-3 minutes. After that, the dentist has about 5 minutes left in order to have time to carry out the necessary manipulations. The most effective drugs are:

  • expasyl;
  • Gingi Track;
  • Magic Foam Cord.

Does gum retraction hurt?

Before starting the procedure, doctors give patients an anesthetic injection (anesthesia), which will relieve all discomfort. After gum retraction, you will need to follow these rules:

  1. After the manipulation, you can not eat or drink hot drinks for 6-8 hours.
  2. After each meal, you will need to rinse your mouth with Furacilin or a decoction of herbs.
  3. Teeth should only be brushed with a soft brush.
  4. Use herbal medicinal pastes.
  5. Do not visit pools and saunas for several days.
