The present disclosure features adhesive compositions and methods of use thereof related to the medical, veterinary, and dental fields.

A dental self-adhesive resin cement is provided comprising a two-component system. A first catalyst component includes one or more acidic monomers. A second base component includes one or more basic fillers. The mixture of the first and second components is polymerizable and has an initial pH that is acidic immediately after mixing and a pH of at least about pH 8 after polymerization.

A dental composition comprising: a) about 1 to about 80% by weight of particulate material including: (i) calcium silicate, calcium aluminate, tetracalcium aluminoferrite, calcium phosphate, calcium sulfate, silica, alumina, calcium oxide, calcium hydroxide, or mixtures thereof; and b) about 1 to about 50% by weight liquid carrier including: (i) water-soluble polymer, (ii) surfactant, the surfactant is selected from the group consisting of alkyl sulfates, alkyl ether sulfates, and sarcosinates, and mixtures thereof; and (iii) water; wherein the particulate and liquid carrier being mixed together to form a hydrate gel material that can harden.

Bioactive, ceramic medical cements and methods for its use in treatment of bones and teeth in mammals are disclosed. This cement is non-exothermic and non-toxic, based upon setting of hydraulic ceramic compounds containing calcia, alumina, and silica phases. The self-hardening cement sets in vivo and in high humidity environments, and can be used in vivo without being easily washed out of the site. It also has dimensional stability, is resistant to acids present in an infection site or supragingivally, and has biocompatibility advantages of low inflammation and the formation of calcification layers in direct apposition to body tissue. Options include the addition of various radiopaque materials, and a variety of delivery systems including powder and liquid, capsule or pouch delivery, multiple pastes, or a unitary paste.

The present invention generally relates to the use of pre-formed bodies of Chemically Bonded Ceramics (CBCs) biomaterial for implantation purposes wherein the bodies are prepared ex vivo allowing process parameters to be optimized for desired long term properties of the resulting CBC biomaterial. More particularly, the pre-formed CBC material bodies of the present invention are sintered. The pre-formed body of CBC material is machined to the desired geometry and then implanted using a CBC cementation paste for fixation of the body to tissue. The invention also relates to a method of preparing pre-formed bodies of CBC biomaterial for implantation purposes, methods of preparing an implant thereof having desired geometry, and a method of implantation of the implant, as well as a kit for use in the method of implantation.

The invention relates to implant materials that are based on hydraulic cements in the form of one or more pastes, suspensions or dispersions that contain mineral and/or organic and/or organomineral solids and that react, when combined or when reacted with an aqueous liquid, to a solid in a cement-type initiation reaction. The invention also relates to the use of these materials as technical, medical-technical and/or pharmaceutical products, especially as bone cements, bone replacement materials, bone glues, dental filling materials and implantable active ingredient carriers. The implant materials according to the invention in the form of one or more pastes, suspensions or dispersions that contain mineral and/or organic and/or organomineral solids are formulated in an excipient liquid in such a manner that the pastes, suspensions or dispersions are stable in storage at normal conditions over a prolonged period of time and that they react, when combined with an aqueous liquid or when added to an aqueous liquid, in a cement-type initiation reaction and set to a solid. The excipient liquid of the mineral paste, suspension or dispersion is substantially water-free, and water immiscible or insoluble or hardly soluble in water in the chemical sense.

The present invention relates to a dental composition including cement and a non-aqueous liquid, wherein the cement includes a first domain including alite, a second domain including belite, and a matrix located between one or more selected from the group consisting of the first domain and the second domain and configured to include silicon (Si)-atom-doped tricalcium aluminate (3CaO.Al.sub.2O.sub.3). A dental hydraulic composition according to the present invention is a single ointment-type composition, and is thus easy to use and exhibits a good aesthetic appearance, high curability and high biocompatibility.
