The invention relates to dental compounds that contain at least one polyacid or at least one polyacid and at least one salt of at least one polyacid. The polyacids used have at least one branch point in the polymer structure and are water-soluble and not cross-linked and their repeat units consist to at least 80 mole % of acrylic acid segments.

The invention relates to a mixing capsule, especially for producing dental materials. The inventive capsule is provided with a cartridge which is closed on one end thereof by means of a piston. A hemispherical cavity is configured in the piston. Said cavity forms an additional chamber and is closed in relation to the main chamber of the cartridge by means of a separating device. A body that is present in the main chamber in the initial state serves for supporting the mixing process and for chopping through the separating device at the beginning of the mixing process in such a way that the main chamber and the additional chamber form a coherent mixing chamber. The body enters the hemispherical additional chamber and acts as a displacing body at the end of the output process. The mixing capsule is provided with a coding.

The invention relates to an adhesive system for fixing dental restorative materials to hard dental substance constituting

Adhesive system for dental purposes

An implantable active substance depot material which contains a glass ionomer cement and one or more chemotherapeutic agents. The active substance depot materials ensure an initially high release rate of the active substance therein and subsequently a discharge of the active substance in small doses until complete depletion of the deposited active substance has occurred.

Implantable active substance depot material

Curable compositions are described which contain a binder and a high propion of fillers having a mean grain size of &lt;50 .mu.m. The filler proportion of the curable compositions is so high that they cannot be used for the intended purpose because of their high viscosity However, they can be liquefied by exposure to oscillation in the frequency range of 20 Hz to 20 MHz with an amplitude of 1 .mu.m to 5 mm so that they are workable and can be employed for the intended purpose.

Dental compositions which can be prepared and worked by the action of

A method is provided for treating cataracts and other eye diseases, and includes the use of photopolymerizable compositions for preparing an intraocular-lens filling material which is used during an operation with an inserted intraocular-lens shell. The photopolymerizable compositions contain the following components:

Open-pored moldings containing the product of the foaming and setting of (a) an aluminum fluorosilicate glass, (b) at least one polycarboxylic acid with an average molecular weight of &gt;500, (c) a foaming agent, other than carbonates and/or hydrogen-carbonates, (d) optionally a chelating agent and (e) water, are suitable in particular as bone substitute material. Production is carried out by homogeneously mixing (a), (b), (c), optionally (d), and (e), then foaming, shaping and setting.
