SU1637777A1 - Method of manufacturing a cermet pin tooth - Google Patents

Abstract

The invention relates to medicine, namely to orthopedic dentistry. The purpose of the invention is to reduce the time of manufacture. When carrying out the method, the preparation is carried out by forming a bed for a pin with a thickness of 1.5-2.0 mm, while maintaining the upper gum portion of the root, on which a bevel is formed at an angle of 25-35 ° C. to the continuation of its side wall, and the ceramics is applied directly to the supporting element before its fixation.

The invention relates to medicine, namely to orthopedic dentistry.

The purpose of the invention is to reduce the time of manufacture.

The method is carried out as follows.

The sharp edges of hard tooth tissues are economically ground both on the protruding gums and in the subgingival areas of the root, expanding the mouth of the pulp cavity in the form of a cone or sphere, depending on its anatomical shape, form a root canal for a pin 1.5 to 2 in diameter , 0 mm depending on the wall thickness of the corn. The hard tooth tissues protruding above the gum economically grind the sharp edges and form a bevel at an angle of 25–35 ° to the continuation of the side wall of the root, the amount of the bevel angle is 25 ° or more, provided the root strength remains optimal, then a two-layer impression is obtained with highly elastic materials (preferably silicone) from the canal, the stump of the root and tooth row.

After that, a collapsible model is made, on which the pin and the support element (of wax) are modeled as a cult-cap, then the wax composition is replaced with a metal. Next, a ceramic mass is applied to the metal structure fitted on the model. During the second visit, the patient is fitted with a cermet construction in the patient's mouth, the shape and color of the tooth is adjusted, and glazing is performed.

In the third visit, fix the metal-ceramic structure in the root channel with cement.

Thus, the method allows the creation of pin structures on the roots, the breaking level of which is located below the gingival margin.

Prevention of fracture of the root contributes to the design of the reference eleo
