Radically polymerizable dental material, which contains a combination of a thiourea derivative, a hydroperoxide and at least one peroxide as well as a transition metal compound as initiator system for the radical polymerization.

Dental materials with improved mechanical properties

Radically polymerizable dental material, which contains a combination of a thiourea derivative, a hydroperoxide and at least one peroxide as initiator system for the radical polymerization.

Dental materials with improved setting behaviour

The invention relates to a radically polymerizable dental material having photochromic properties, which contains at least one compound of formula (I) and optionally radically polymerizable monomers, an initiator for radical polymerization and other components.

Dental materials with light-induced reversible coloring

Radically polymerizable dental material which contains as initiator for the radical polymerization a combination of a thiourea derivative and a bisacyldialkylgermanium compound.

Photopolymerizable and dual-curing dental materials based on thiourea derivatives

Monomer mixture for the preparation of dental materials, which contains at least one low-volatile monomethacrylate, at least one highly viscous polyfunctional methacrylate and at least one low-viscosity polyfunctional methacrylate.

Monomer mixture for the preparation of dental materials

An applicator kit, for dental purposes. has an application element with a grip area for handling, and also has a shaft, on a tip of which is disposed an application member, preferably in the form of a micro-brush that is provided with a reaction substance. A cup shaped sealing mechanism surrounds the shaft and the application member. The cup shaped sealing mechanism is slidably received within a housing which also receives a low velocity fluid initially spaced away from the cup-shaped sealing mechanism. The reaction substance on the application member is activated by pressing the sealing mechanism and application member into the fluid within the housing which causes the fluid to wet the application member.

Applicator and method of applying

A mixing arrangement and method for mixing a substance for the field of dentistry are provided, with the production of the substance requiring at least one base material and one reactant. A catalyst is applied to a base surface as reactant in a solid or semi-solid layer. The unit comprising catalyst and base is prefabricated, and the base material, particularly in liquid form, can be applied or introduced to the base surface that is provided with the catalyst prior to using the substance. The substance can be applied ready for use by means of an application element after the catalyst and base material have been mixed.

Mixing arrangement

The invention relates to a dental material with at least one polymerizable binder and at least one filler containing a redox-initiator system for the radical polymerization, which comprises an initiator and an activator. The material is characterized in that the filler contains a homogeneous mixture of a first part of the filler, which is mixed with the initiator, a second part of the filler, which is mixed with the activator, and a third part of the filler, which does not contain a component of the initiator system. The materials are particularly suitable as cements and filling materials.
