    Abstract: 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: (RSi)—(CR1R2)n—(NH—C(O)—O—CH2—CH2)q—N(R5)—C(O)—NH—(CH2—CH2—O)t—CR3R4—CH2-(A) Formula I (RSi)—(CR1R2)n—NH—C(O)—O—CR3R4-(L)q-CH2-(A) Formula II, wherein: RSi is a silane-containing group of the formula —Si(Yp)(R6)3-p, wherein Y is a hydrolysable group, R6 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.

    Abstract: The present disclosure provides an additive manufactured article including a first portion and a second portion integral to the first portion. The second portion includes a coupling configured to engage a tool, as well as a frangible section at a connection point to the first portion. Further, a method of making the article is provided, including obtaining a photopolymerizable material and selectively curing the photopolymerizable material to form the article. Another method is provided, including obtaining a digital three-dimensional model of a patient's dental anatomy comprising a tooth in need of restoration and computing a digital three-dimensional model of a dental restoration to fit within the patient's dental anatomy, including determining a shape of the dental restoration. Optionally, the patient's dental anatomy may be prepared for a dental restoration prior to obtaining the digital three-dimensional model. A kit is also provided, including the article and a tool configured to attach to the coupling of the article. Having a coupling integral to the rest of the article allows for easy attachment to a handling tool.
