Abstract
Description
[0001] A new, simple, and more effective technique for the rapid and safe disposal of mercury by applying mini bamboo tablets, impregnated after application, has been developed. This method is applicable to the production of dental inlay material in dental cavities.
[0002] The technology involves a simple yet efficient procedure for producing dental inlay material for dental cavities. It is based on patent EP 1 348 417 Bl. Mercury from amalgam fillings can cause a variety of health problems. The main symptoms of amalgam intoxication and intolerance are diverse, which also led to the ban on the use of dental amalgam from January 1, 2025, under Regulation (EU) 2017 / 852 on mercury.
[0003] After the removal of an amalgam or old composite filling, the dentin may be contaminated. It is therefore important to thoroughly clean and disinfect the dentin to remove any potential contaminants and create a healthy foundation for new fillings or other dental treatments.
[0004] Gentle cleaning can be achieved through a new technique that uses compressed tablets with a diameter of 2 to 3 mm. These tablets are made of the following materials: Bamboo flour from the food industry Advantages:Natural origin
[0005] Absorption mechanism and water binding are very good Alternative materials
[0006] Other materials that can also be used for compressed tablets are: Activated carbon, acacia fiber flour Inulin Psyllium husk flour Cellulose sheets that are punched Purpose: Production of tablets Press tool
[0007] The tablets are manufactured using a special tablet pressing tool consisting of three parts. It is a quadruple tool that can be used both for pressing powder and as a punching tool. The tool consists of a die (< Fig. 2) and two plates with upper ( Fig. 1) and understampingFig(2). Technical description
[0008] The die is filled with powder and placed on the plate with the lower punch.
[0009] The plate is then manually placed on the mold using the four punches. The mold is compressed using a hand press with a pressure of 500 kg. The tablets are then pressed out of the mold using a small ejection tool.
[0010] Alternative use as a punching tool
[0011] The tool can also be used as a punching tool, for example to punch cellulose sheets.
[0012] The tablet is applied to the dental cavity after it has been hollowed out and the old filling removed. The tablet is then moistened with 10% sodium thiosulfate (2-3 drops). This can be done either directly in the mouth with a disposable pipette or on a mixing pad. The contact time is 10-15 minutes, after which the temporary filling is removed and the cavity is rinsed with plenty of water and good suction.
