Problems solved by technology

The existing oral material mixing boards mainly include cardboard and glass board, but the inventors of the present application found that: when using different oral material mixing boards to mix glass ionomer materials, the hand feeling is completely different, and the viscosity of the material is not the same. The strength and mechanical properties are also significantly different; the use of cardboard for mixing is not easy to clean and sterilize, and it is inevitable that some powder will remain on the edge during the mixing process, and with the change of the thickness of the cardboard, the thickness of the cardboard If the surface hardness changes, the mixing feel will change, which will have a negative impact on the material performance; and the glass plate is too hard, and it is easy to break during the disinfection and sterilization process

Embodiment 1

[0012] An oral material mixing plate is a medical silicon rubber plate with a Shore hardness between 40 and 80.

[0013] Specifically, the medical silicone rubber sheet with a Shore hardness between 40 and 80 is not only soft and hard for material mixing, durable and not easy to break, but also has a good surface hydrophobicity, easy to clean, sterilize and disinfect, and will not damage the mouth of the mixed material. affect the physical and mechanical properties of the material. In practical application, the medical silicone rubber plate is preferably a cuboid with a length of 80mm, a width of 65mm, and a thickness of 8mm, which is not only easy to hold and use, but also provides users with a good feel. Moreover, the manufacturing cost can be effectively reduced, and an area for mixing conventional clinical materials can be provided for operators.

Abstract

The invention discloses a dental material blending plate. The dental material blending plate is a medical silicone rubber plate with the shore hardness being 40-80. The dental material blending plate has the hardness suitable for material blending, is durable, has small possibility of being broken, is good in surface hydrophobicity, and is easy to clean, sterilize and disinfect, and no influences are caused to the physical and mechanical properties of the blended dental material.

Description

technical field [0001] The invention relates to the technical field of oral material mixing, in particular to an oral material mixing plate. Background technique [0002] Oral materials, also known as dental materials, are substances or combinations of substances that are specially prepared and / or provided for dental professionals to engage in dental business and / or related operations Mold materials, model materials, denture materials, filling materials, bonding materials, planting materials, dental preventive health care materials, lining materials, maxillofacial prosthesis materials, orthodontic materials, embedding materials, grinding and polishing materials, etc. Various materials used to restore the anatomical shape, physiological function and aesthetics of teeth or dentition. [0003] Most oral materials need to be mixed, and the mechanical properties of the mixed materials directly affect the clinical use effect, and the compressive strength is the main index reflect...
