Abstract

The invention discloses an occlusal pad for reducing bacterial attach rate. The technical scheme of the occlusal pad is characterized in that the occlusal pad comprises PMMA resin and a coating applied to the PMMA resin, wherein the coating is prepared from the following components by weight: 28-50 parts of ethyl orthosilicate, 0.98-10 parts of a silane coupling agent, 52-114 parts of absolute ethyl alcohol, 82-192 parts of deionized water, 6-10 parts of dilute hydrochloric acid, 10-16 parts of vinyl trimethylsilane, 6-10 parts of vinyl chloride, 2-6 parts of bisphenol alpha dimethacrylate, 1-4 parts of trimethyl[(1-methylvinyl)oxy]silane, 0.1-1 part of azobisisobutyronitrile and 6-8 parts of an antibacterial agent. Hydrophobic antibacterial paint is prepared with the sol-gel method, the surface of the occlusal pad is covered with a hydrophobic antibacterial coating, and accordingly, the bacterial attach rate is reduced.

Description

technical field [0001] The invention relates to the field of oral medicine, in particular to an occlusal pad which reduces the bacteria adhesion rate. Background technique [0002] Polymethyl methacrylate (PMMA) is a common material for occlusal pads because of its stable performance, beautiful color, easy processing and repair, and low price. However, the porosity and water absorption of PMMA materials also make it easy for pathogenic bacteria to adhere to its surface, causing dental caries, periodontitis, denture stomatitis and other oral diseases. [0003] In order to reduce the bacterial adhesion on the surface of the occlusal pad, mechanical cleaning, chemical soaking and local application of antibacterial drugs are often used clinically. The commonly used physical cleaning method is to mechanically scrub the occlusal pad with a toothbrush and toothpaste, but the effect of this method is not very satisfactory: the hyphae of Candida albicans easily extend into the pores...
