Problems solved by technology

[0005] The manufacturing method of the all-enveloping ultra-thin porcelain veneer disclosed in this patent document, although the prepared porcelain veneer has strong compression resistance, fits the teeth, and is not easy to collapse, but it needs to grind away a lot of tooth tissue. The color of the side repair is not good, which affects the aesthetic effect

Embodiment 1

[0031] see figure 1 , a dental hybrid porcelain veneer, comprising a lingual porcelain veneer 1 and a labial porcelain veneer 2 for covering a tooth body 4, the lingual porcelain veneer 1 fully covers the lingual side of the tooth body 4, the The labial porcelain veneer 2 partially covers the labial side of the tooth body 4, and a junction line 3 for docking and bonding is formed between the lingual porcelain veneer 1 and the labial porcelain veneer 2, and the junction line 3 is located at 1 / 2 of the incisal edge of the tooth body to the labial tongue.

[0032] The lingual porcelain veneer 1 is made of zirconia, and the labial porcelain veneer 2 is made of feldspar ceramics.

Embodiment 2

[0034] see figure 2 , a dental hybrid porcelain veneer, comprising a lingual porcelain veneer 1 and a labial porcelain veneer 2 for covering a tooth body 4, the lingual porcelain veneer 1 fully covers the lingual side of the tooth body 4, the The labial porcelain veneer 2 partially covers the labial side of the tooth body 4, and a junction line 3 for docking and bonding is formed between the lingual porcelain veneer 1 and the labial porcelain veneer 2, and the junction line 3 is located on the lingual side. The proximal incisal end of side porcelain veneer 1 avoids the occlusal contact area by 2mm, forming a right-angled shoulder.

[0035] The lingual porcelain veneer 1 is glass ceramics, and the labial porcelain veneer 2 is feldspar ceramics.

Abstract

The invention discloses a dental hybrid porcelain veneer, which belongs to the technical field of dental medical devices, and is characterized in that it includes a lingual porcelain veneer and a labial porcelain veneer for covering teeth, and the lingual porcelain veneer is completely Covering the lingual side of the tooth body, the labial porcelain veneer partially covers the labial side of the tooth body, a junction line for butt joint and combination is formed between the lingual side porcelain veneer and the labial side porcelain veneer, the junction The line is located at the proximal incisal end of the lingual porcelain veneer and avoids the occlusal contact area by 2mm, forming a right-angled shoulder or at the 1 / 2 of the lip-lingual direction of the incisal edge of the tooth. The lingual porcelain veneer is made of zirconia or glass ceramics. The labial porcelain veneer is feldspathic ceramic. The hybrid porcelain veneer prepared by the invention has both mechanical and aesthetic properties, and retains more tooth tissue. There are no teeth on the lingual side, and the amount of teeth on the labial side is less than 0.5mm or no teeth. It is suitable for people with teeth on the lingual side. The occlusal space, occlusal reconstruction with normal lip color and fixed repair with occlusal space on the lingual side have strong applicability.

Description

technical field [0001] The invention relates to the technical field of dental medical instruments, in particular to a dental hybrid porcelain veneer and a manufacturing method thereof. Background technique [0002] Porcelain veneer is a fixed restoration, which is mostly used for patients with tooth surface defects, staining, discoloration, enamel dysplasia, tetracycline teeth, dental fluorosis, deformed teeth, excessive interdental spaces, proximal caries and incisal defects, etc. , using a relatively less molar restoration method, the porcelain restoration material is bonded to the tooth surface to restore the normal shape of the tooth and improve its color. [0003] In the prior art, usually the labial side of the tooth is fully covered with porcelain veneers, and the lingual side of the tooth is partially covered with porcelain veneers, and both the labial and lingual sides of the teeth are made of the same material. Porcelain veneers are divided into two types accordin...
