Abstract
The present invention provides an oxide ceramic pre-sintered body for dental use and a method of production thereof having excellent machinability with a low probability of chipping while exhibiting high translucency after sintering. The present invention relates to an oxide ceramic pre-sintered body for dental use comprising oxide ceramic particles with an average primary particle diameter of 50 to 300 nm, and pores, and having a D10 of 20 nm or more and a D90 of 90 nm or less in a cumulative distribution of pores within the pre-sintered body. The oxide ceramic pre-sintered body for dental use has a relative density of preferably 43 to 63%. The oxide ceramic pre-sintered body for dental use has a BET specific surface area of preferably 5 to 25 m2/g as measured in compliance with JIS Z 8830:2013.
