The invention relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit comprising a Paste A and a Paste B, Paste A comprising water, acid-reactive inorganic filler A, phyllo silicate(s), Paste B comprising water, poly-acid, non acid-reactive filler B, optionally chelating agent. The invention also relates to a hardenable composition obtainable by combining the pastes of the kit or parts and to the use of such a composition as or for preparing a dental cement, dental filling material, dental core build up material or dental root channel filling material.

Bone or dental filler materials include liposomes, which give them disinfectant properties. These filler materials are used, in particular, for filling dental pulp or a bone defect.

The present disclosure provides an inorganic dental filler including a surface treated with at least one silane. Exemplary silanes described in the present disclosure for the surface treatment of the inorganic filler include silanes of Formula I and/or Formula II: (R.sup.Si)(CR.sup.1R.sup.2).sub.n(NHC(O)OCH.sub.2CH.sub.2).sub.qN(R.sup.5)C(O)NH(CH.sub.2CH.sub.2O).sub.tCR.sup.3R.sup.4CH.sub.2-(A) Formula I (R.sup.Si)(CR.sup.1R.sup.2).sub.nNHC(O)OCR.sup.3R.sup.4-(L).sub.q-CH.sub.2-(A) Formula II, wherein: R.sup.Si is a silane-containing group of the formula Si(Y.sub.p)(R.sup.6).sub.3-p, wherein Y is a hydrolysable group, R.sup.6 is a monovalent alkyl or aryl group, and p is 1, 2, or 3. Methods of making and using the surface treated inorganic dental fillers are also disclosed.

The invention relates to a method to produce a medical form body of lithium silicate glass ceramic. To increase its strength it is proposed that a surface compressive stress is created in a form body of lithium silicate glass, or containing lithium silicate glass, through the replacement of lithium ions by alkali metal ions of greater diameter. For this purpose the form body is covered with a paste that contains alkali metal.
