A bone cement paste containing a powder component comprising α-tricalcium phosphate (α-TCP) particles having an average size greater than or equal to 9 μm, and a liquid component comprising blood is disclosed. A method for preparation of the phosphocalcic cement composition is also disclosed.

A dental liner and a manufacturing method therefor are disclosed. The dental liner is a dental liner for coupling feldspar porcelain and zirconia and includes: silicon dioxide; aluminum oxide; 1,4-butanediol for maintaining the moisture of the dental liner and preventing the generation of layers; and a zirconia powder for coupling the dental liner and zirconia by strengthening chemical bonding of the dental liner and zirconia.
