Spraying wear-resistant coatings. Ceramic coating

Distribution of thermal values \u200b\u200bin the furnace in different fields, in the rear and left-right parts. Differences are noted and used to sintering crowns and dental bridges by placing them into certain places. Clinical observations correlated with experimental laboratory samples showed low stability of fixation between metal and ceramic mass by covalent binding of two materials oxides.

The binding was created to eliminate failures manifested in the separation of metal ceramic mass. In metal-ceramic technology, with the advent of gluing, prostheses are characterized by particularly high stability, the phenomenon of separation on the metal ceramic interface is absent.

The use of both processes, oxidation and gluing to fix the ceramic mass on the metal surface can sometimes be accompanied by the separation of ceramic mass, especially if excessive oxidation is achieved due to excess oxides. In conclusion, the connection used has two big advantages.

Reduces the degassing phase and the oxidation of the alloy - the phase in which failures may occur in the oxidation. Fixing the ceramic mass on the metal surface is more stable. Arguments to support the second technological process are. Clinical - metal ceramic prostheses obtained after this procedure are not accompanied by failures. Metal-ceramic crowns, when sewing with a disk to remove on the dental flan, ceramics does not come down from the metal.

The following sample can be demonstrated laboratory and experimental: ceramic mass, besieged and sintered on the surface of the alloy with a reduced thickness of only 0, 10 mm. On two piece of metal. On one part, the ceramics is fixed with gluing, and the other is fixed by the oxidation phenomenon.

After sintering the ceramic mass on both metal fragments, the plastic deformation is performed with a tendency to bend. Ceramic mass, fixed with gluing, will crack without disconnecting. The ceramic mass, fixed by oxidation, deformation of the metal substrate, cracks and falls.

It is always recommended to strictly follow the instructions in the avenue attached to the product. The size of the binder layer applied to the metal surface. The temperature required for metal fixation. As long as the temperature in the furnace reacts.

Currently, the adhesive products are also opaque. Once the binding is deposited and sinters, it turns out opaque. The binder of the gold amalgam is strongly sticking to the surface of the metal, and the platinum particles are evenly distributed, strongly attached to the metal surface.

Aesthetic success of a tooth ceramic mass. Reproduction of chromatic nuances of natural teeth is possible only when evaluating the role of an opaque porcelain. Opaque porcelain is used for the following roles. If the opacity color is directed, the color for the entire crown is selected and selected. The choice and distribution of opaque colors is especially important operations.

An opaque layer is inserted between transparent particles. Binding structure highly related to physico-chemical, ceramic on the surface of the alloy. It is mixed in certain proportions with a ceramic mass for dentin and enamel. The opacity color is obtained by introducing a dye without excessive use of the dye.

Technique use opaque color. Dark opaque - more dark colorthan all areas of natural teeth of neighboring teeth. If it is impossible to get one opaque, make a mixture of different existing types. If the desired result is not reached, use the dye.

Transparent is applied to the surface of the metal to get a layer of a certain size. The deposition is carried out using a brush with an unsupported tip. The amount of opacity is taken at the top of the brush to form a small sphere. It is preferable to apply the first layer very thin to avoid the inclusion of air bubbles. The first layer is moisturized before applying the second layer to facilitate the penetration of opaque particles into the binding mass. The color distribution is opaque for three areas: cervical, cutting and medium, is produced to obtain a color close to the color of a natural tooth.

The maximum density of the ceramic tabletop can be obtained if a ceramic capacitor is used. When using an opaque ceramic capacitor, an intimate use of opaque metal is realized, which makes it a solid connection. After applying an opaque material, the napkin is used to absorb excess water and combustion preparation. Porcelain will not be dry because it takes permanent humidity.

The dental porcelain is postponed to obtain an anatomical shape of a tooth crown, different from the anatomy of a metal circle. Transparency has a thickness of about 0, 2 mm, which is enough for the roles that she has. The crown finally has walls with a total thickness of 1 mm. Transparent porcelain has a size of 0, 5 mm, which corresponds to the enamel of a natural tooth.

Dental porcelain can be made by mixing a porcelain crown with opaque in proper proportions. Noble alloys that were used in the past, due to very high cost, limited an indication of metal products. These alloys are sold at a much lower price than noble alloys.

Currently, this group has many non-native alloys that offer optimal conditions for frequent use. Over the past two decades, these alloys were used in metal-ceramic technologies for the manufacture of microtects and dental bridges.

First, the characteristics of these alloys, especially the accuracy of castings, were questioned. Special packaging mats were gradually developed with a compression ratio to compensate for volumetric changes in the liquid alloy in the cooling and solidification phase.

Now the properties of these nickel and chromium alloys in many respects are largely characteristic of the properties of noble alloys. Nickel and chrome alloys have characteristics that exceed alloys of noble alloys: hardness and elasticity to plastic-elastic deformation. These functions recommend using them on a wider palette of applications with noble alloys.
