Problems solved by technology
[0002] In the current technology, dental fillings in dentistry have not been able to solve the problem of microleakage in global dentistry. At present, cement powder or silver amalgam is commonly used for dental fillings. Dental caries can easily fall off after filling (average use less than 3 years), the cavity at the junction of the two teeth is more likely to fall off after filling (average less than 1 year), and the traditional filling method cannot fill the porcelain material with high strength, high wear resistance, acid and alkali resistance, and realistic color

Embodiment Construction
[0022] The specific embodiment is described below in conjunction with accompanying drawing;
[0023] The thickness of dental sheet in above embodiment is all between 0.1mm---10mm, as image 3 . Figure 4 For the thickness shown, when filling the tooth, the first step is to prepare the hole shape according to the size of the cavity or tooth defect: ordinary dental drill bits can be used, and special dental drill bits that match the dental film can be used for preparation. The second step is to choose the appropriate size dental tablets, such as figure 1 The diameter of the tooth piece shown can also be polished. The third step is to fill the root canal filling medicine into such as Figure 4 In the concave surface of the cemented surface of the tooth piece shown, the fourth step: fill the mixed cement or other filling materials into the cavity and / or smear on the tooth piece, and then press the tooth piece into the tooth It can be done inside the cave.

Abstract
The invention discloses a dental film used for filling a tooth in dentistry. The invention overcomes the defects of slight leakage, poor hardness, easy exfoliation and dark color in conventional dental cavity filling materials. The invention adopts pre-processed ceramic thin films which have different sizes and exceptional hardness. The color of the ceramic thin film is similar to a tooth. The thin film is provided with an elastic sealing ring that can solve the problem of slight leakage when the tooth is filled. The cementation surface of the thin film is the surface with concave structure. Various antimicrobial drugs can be placed in the concave surface. When the tooth needs to be filled, a proper dental film is selected out according to the size of the cavity. The dental film and cement are filled in the cavity at the same time.
Description
technical field [0001] The invention relates to a medical device, in particular to a tooth piece used for filling dental caries in dentistry. Background technique [0002] In the current technology, dental fillings in dentistry have not been able to solve the problem of microleakage in global dentistry. At present, cement powder or silver amalgam is commonly used for dental fillings. Dental caries can easily fall off after filling (average use Less than 3 years), the cavity at the junction of the two teeth is more likely to fall off after filling (average less than 1 year), and the traditional filling method cannot be filled with ceramic materials with high strength, high wear resistance, acid and alkali resistance, and realistic color. Contents of the invention [0003] The purpose of the present invention is to provide a filling for dental caries or tooth defects that can solve the problem of micro-leakage, long service life (15 years on average), high mechanical strengt...
