A solid freeform fabrication material set includes a material A for solid freeform fabrication and a material B for solid freedom fabrication. The material A includes a polymerization initiator A and at least one of an organic particle and an inorganic particle. The material B includes a polymerizable compound B.

A framework for a removable, partial or complete prosthodontic device is made by machining, using a CAD/CAM technique, a disc 2, made from polyetheretherketone, to define the framework 4. Prosthetic teeth and gums can be secured to the framework to define the prosthodontic device.

A method of smoothing teeth is disclosed, the utility of which is based on surprising empirical evidence achieved via practice of a method involving application of calcium thereto and maintaining it in contact therewith by application of a composition of matter that adheres to said teeth.

An endodontic filling material comprising a biodegradable thermoplastic polymer. A bioactive substance may also be included in the filling material. The thermoplastic polymer acts as a matrix for the bioactive substance. The composition may include other polymeric resins, fillers, plasticizers and other additives typically used in dental materials. The filling material is used for the filing of root canals.

The present invention relates to a resin composition, in particular suitable for printing, a kit comprising the components of the resin composition, a printing method utilizing the resin composition, a polymer obtained by the printing method, an article comprising or formed from the polymer, and uses thereof. The resin composition may be in particular suitable for printing and comprises at least one compound C1 having (i) at least one terminal alkyne functional group, and (ii) at least one functional group selected from the group consisting of a carbonate, a carbamate, and an ether; and at least one compound C2 having at least two thiol functional groups.

Provided is a resin composite material that has more excellent toughness than that of a related-art resin composite material, and hence, while having rigidity, does not undergo breakage even when a certain strain is applied thereto. Specifically, provided is a resin composite material, including: (A) 100 parts by volume of a polyaryletherketone resin having a melt viscosity of from 210 [Pa.Math.s] to 350 [Pa.Math.s] at a temperature of 370 C. and a shear rate of 1,220 [1/s]; and (B) 20 parts by volume to 60 parts by volume of inorganic particles. Also provided is a method of manufacturing the resin composite material.

Dental material, which contains an ene compound with two or more CC multiple bonds and a thiol according to general Formula (1) or an oligomer based on such a thiol,

##STR00001##

wherein n, p and m are chosen such that the thiol has a total of at least 3 SH groups.

The invention relates to a polysiloxane compound comprising specific siloxane units, curable dental materials comprising one or more than one polysiloxane compound according to the invention, cured dental materials obtainable from the curable dental materials according to the invention, a method for preparation of polysiloxane compounds according to the invention, a method for preparing curable polysiloxane compounds according to the invention and a method for preparing cured dental materials according to the invention.
