Problems solved by technology
Since the decorative porcelain material layer is mostly a transparent layer structure after sintering, such as figure 2 As shown, the above-mentioned transparent layer structure makes the prosthesis close to the oral cavity, that is, the dark area where the porcelain at the bottom of the prosthesis will transmit the gum tissue, and because the reflected light is weak, when the above-mentioned dental prosthesis is used, the prosthesis Porcelain at the bottom is attached to the edge of the oral cavity and presents a dark dark zone, which causes visual defects in dental restorations and cannot meet the aesthetic requirements of high-quality dental restorations

Embodiment Construction
[0038] Such as figure 1 As shown, in the prior art, the porcelain veneer material layer 2 is not entirely covered on the surface of the base 1 , and the veneer veneer material layer 2 is not provided on the side of the base 1 close to the gum 3 . During the later heating and sintering process of the dental restoration, due to the shrinkage of the decorative porcelain material layer 2, there will be a gap between the base 1 of the zirconia title and the gum 3 that is not covered by the porcelain decorative material layer 2, which will affect the dental restoration. overall aesthetics. In order to avoid the above-mentioned gaps, the decorative porcelain material layer 2 is arranged outside the base 1 in a fully covered manner, relying on the viscosity or tension of the ceramic decorative material itself to avoid cracks or voids on the surface of the base 1 .
[0039] However, if figure 2 As shown, a new problem arises: after the light enters the veneer between the base 1 and ...

The invention discloses a restoration body structure for the dentistry and a production technology, and relates to the technical field of restoration body preparation for the dentistry. The restoration body structure comprises a base and a transparent veneering porcelain material layer wrapping the surface of the base; the surface and / or the portion, close to the surface of the side, close to thegum tissue, of the veneering porcelain material layer are / is provided with reflection layers / a reflection layer, and the reflection layers are used for reflecting light entering the portion between the base and the gum. By adopting the restoration body structure, light entering the veneering porcelain between the base and the gum can be reflected, due to the fact that reflection is formed on the reflection layers, and in essence, the color of the base is reflected, so that the phenomenon that weak reflection from the restoration body veneering porcelain to the gum and adjacent areas forms a dark color area zone can be avoided, and the aesthetic nature of the whole restoration body can be improved by mixing different reflection layer colors.
Description
technical field [0001] The invention relates to the technical field of preparation of dental prosthesis, more specifically, it relates to a dental prosthesis structure and production process. Background technique [0002] Dental porcelain restorations generally consist of a substrate made of a porcelain material including zirconia and a layer of porcelain material (veneer) attached to the substrate. In the process of manufacturing the above-mentioned dental restorations, it is first necessary to pile up the decorative porcelain material on the zirconia base. After the decorative porcelain material is compacted, the decorative porcelain is stably fixed on the base by milling and sintering to achieve beautification of the teeth. The effect of the restoration. [0003] Because the volume of the decorative porcelain material will shrink during the heating and sintering process, if the decorative porcelain does not completely cover the substrate, that is, the decorative porcelai...
