摘要:
The invention relates to a method for producing an orthodontic component (1) formed by a polycrystalline ceramic structure, wherein the powder that is used is formed into a green body and subsequently sintered in a temperature range having a lower limit of more than 1900° C., in particular 2100° C., and an upper limit of 2500° C., in particular 2400° C., preferably 2200° C., over a duration having a lower limit of 3 hours, in particular 5 hours, preferably 7 hours, up to an upper limit of 24 hours, in particular 15 hours, preferably 10 hours. Subsequently, the sintered component (1) is cooled down to room temperature, wherein the material is formed in a thickness of 0.5 mm having inline translucency with a lower limit of 70%, in particular 85%, and an upper limit of 100%.
