A process for fabricating dental form pieces for dental restoration and replacement parts is provided and includes the step of applying a material, on a firm support or a fluid medium, by a three dimensional plotting technology in a layer by layer manner. The material has micro cords and / or micro drops which include at least one of a meltable, polymerizable, polycondensable, and polyaddable constituent element that is an unfilled monomer, a reinforced monomer, oligomer, polymer, or a ceramic element. The process also includes the step of hardening the applied material by cooling of the material, chemical reaction, polymerization with thermal handling, or polymerization by irradiation of the material with UV or visible light.

Compositions, particularly for forming dental products, having a hardenable self-supporting structure with sufficient malleability to be subsequently customized into a second shape and then hardened, and methods.

Disposable dental mouthpiece-strip which has been pre-impregnated with dental substance which can either be placed in the mouth by the user or inserted in the mouth by a dentist for oral treatments, such as teeth whitening treatments, fluoride treatments, or medical treatments, such as the application of anasthetic or antimicrobal / antiseptic treatments. The mouthpiece-strip is made with a foldable structure such as a thin strip of wax with a section of porous material (sponge) that holds the treatment dental product (liquid or gel). The mouthpiece-strip is disposable; the amount of time it is worn is determined by the type of dental treatment. The mouthpiece-strip may be adjusted in size by cutting it with scissors. The wax used for the mouthpiece is non-toxic and allows for a perfect adjustment in the mouth by contouring to the teeth during adjustment by the user. To enhance the fit in the mouth, the inner surface of the mouthpiece-strip may contain a thin layer of non-toxic sticky adhesive. The porous (sponge) strip attached to the wax strip is an inert, nontoxic material which is easy to process and inexpensive. It is attached to the wax strip with a non-toxic adhesive.

The present invention is generally related to a product and process to reduce the microbial contamination on organic matter, such as processed meat, fruits and vegetables, plant parts, inanimate surfaces such as textiles and stainless steel, and in the mouth or on dental products. In particular, the invention is related to a product and process to disinfect surfaces using an antimicrobial composition containing an antimicrobial lipid, an enhancer selected from the group consisting of bacteriocins, antimicrobial enzymes, sugars, sugar alcohols, iron-binding proteins and derivatives thereof, siderophores, and combinations thereof, and optionally a surfactant.

The present invention is directed to compositions, products and methods useful for bone and tooth mineralization. The compositions comprise polymer microcapsules containing aqueous salt solutions. The shells of the microcapsules can be semi-permeable or impermeable. Solutions of calcium, fluoride and phosphate salts are particularly useful in the compositions of the invention. The microcapsules are preferably prepared by surfactant free inverse emulsion interfacial polymerization. Bone products include cements, scaffolds and bioactive glass. Dental products include pastes, gels, rinses and many other dental materials.

Lithium silicate materials are described which can be easily processed by machining to dental products without undue wear of the tools and which subsequently can be converted into lithium silicate products showing high strength.

Dental composition, product and process using a silicon containing abrasion resistant material. The dental products formed are abrasion resistant and self-lubricating across their entire cross sections. Dental compositions useful for forming dental products in accordance with the invention preferably includes an ethylenically unsaturated silane. The composition is formed into a dental prosthesis, such as an artificial tooth, inlay, onlay, facing, crown or bridge.

The present invention relates to the use of free-radically curable compositions, comprising chain-like and / or cyclic and / or cage-type polysiloxanes substituted by free-radically polymerizable groups and having at least 3 silicon atoms and / or mixed forms thereof, disiloxanes substituted by free-radically polymerizable groups, optionally one, two, three or more free-radically curable monomers having no silicon atom, fillers, initiators and / or catalysts for free-radical polymerization, and also further customary additives, in additive manufacturing methods, preferably in stereolithography (SL) and digital light processing (DLP). The present invention further relates to the use of the cured free-radically curable compositions, preferably for production of dental products.

Dental products such as toothpastes, mouthwash and dental floss are disclosed which products are enhanced by having dissolved, dispersed or coated thereon a compound which promoted bone growth. Preferred compounds are peptide sequences comprising 10 to 50 amino acids are disclosed. The sequences are characterized by containing an integrin binding motif such as RGD sequence and the remainder of amino acids contiguous with the RGD sequence in matrix extracellular phosphoglycoprotein. The sequences may be formulated for dispersed in toothpaste or a mouthwash and administered to enhance bone / tooth growth. When the dental products are used repeatedly over time they enhance good dental health.

The invention discloses a method for making a dental model mold through 3D printing. The method comprises the steps that a three-dimensional tooth model is established through 3D calculation according to Dicom-format CT scanning fault data of patient's teeth, and then a three-dimensional model of the dental model mold is obtained through processing and output to a 3D printer in an appropriate format to obtain the dental model mold of a patient. The gypsum model of the patient's teeth and whole or single / multiple resin or ceramic false teeth and the like clinically used in oral medicine can be obtained by filling gypsum, tooth making resin, ceramic powder and other materials in the obtained mold. A traditional impression taking method is replaced by utilizing the dental model mold made through 3D printing, the discomfort of the patient is greatly decreased, and various failure phenomena in the traditional impression taking operation are decreased. In addition, the dependence on the operator's proficiency of the making quality of traditional dental products is effectively decreased while the designability of the dental model, false teeth and other dental products is enhanced through computer aided design, the clinic practicability is good, the cost is low, and the method is easy to popularize.
