An orthodontic bracket and archform system that uses friction-free mechanics are disclosed. The archform can have a male fastener that can be retained within an orthodontic bracket. The orthodontic bracket can have varying locking mechanism, such as deflectable tabs, springs, locking pins, and others, that can cooperate with features of the male fastener to prevent sliding between the archform and the bracket.

The disclosure related to a resin composition for molding device for dental restoration comprising 10 to 50 parts by weight of an urethane acrylate oligomer with a functionality less than 4, 20 to 40 parts by weight of morpholino-group containing acrylate monomera morpholino-group containing acrylate monomer, 10 to 40 parts by weight of a polymerizable acrylate monomer composition and 0.5 to 5 parts by weight of a photoinitiator, wherein the polymerizable acrylate monomer composition comprises 40 to 60 parts by weight of an alicyclic acrylate monomer and 40 to 60 parts by weight of ether-bond containing aliphatic acrylate monomeran ether-bond containing aliphatic acrylate monomer. The shore hardness of the resin composition after being cured of the present invention is not less than 70D and the flexural strain thereof is not less than 0.15. The resin composition can provide the molding device composed of the resin composition an excellent accuracy of shape and dimensional, and an outstanding demoldability and firmness when being removed after the restoration processes.

A tooth arrangement decal constructed and arranged to facilitate the rapid communication of the placement of prostheses with respect to prosthetic teeth on a wax rim and a method of using the same is provided. The tooth arrangement decal may instruct the arrangement of teeth, and in particular, central incisors, lateral incisors, and canines. The tooth arrangement decal may be constructed and arranged to eliminate the need for tedious measurements and inscription of markings on a wax ring to indicate the appropriate location for prostheses during denture set-up.

A method for directly printing orthodontic and dental appliances on the teeth of a patient. The tooth is scanned with a scanner which is communicated with a computer controller configured to recognize the anatomy of the tooth. The surface of a tooth of the patient is then prepared in order to receive the type of appliance designated for the patient. Using image data from the print head, the computer controller prepares a three-dimensional blueprint or design of an appropriate orthodontic or dental appliance. The computer controller controls the type and amount of material that is distributed through the print head only when the print head passes over the recognized anatomy so as to directly print the corresponding appliance onto the tooth layer by layer as the print head makes successive passes over the surface of the tooth.

A dental filling material comprising bioactive borate glass particles, wherein the particles are at a concentration of 40-60 wt %, a co-monomer resin blend, a photoinitiator, and a co-initiator is provided. Method for applying the dental filling material to a tooth structure are also provided. The temporary filling material re-mineralizes the tooth structure and is removed after 1-7 days for the placement of a permanent filling material.

A method that includes the step of using a person's fingers to push a dental composition into engagement with a damaged tooth surface of a damaged tooth thereby adhering the dental composition to the damaged tooth surface and covering at least a portion of the damaged tooth surface. The dental composition includes a base material comprising at least one of the following compounds chosen from the group consisting of: a product consisting of one or more hydrocarbon-based waxes that may also include inorganic fillers and/or organic fillers; an uncured, uncrosslinked silicone high consistency rubber base; and a hydrophobic water insoluble solid material that is malleable at 37° C. or lower and safe for a human oral environment. The base material has at least one dry, powdered hydrophilic polymeric substance engaged with and dispersed on one or more surface of the base material.

The invention relates to the field of medicine, namely dentistry, and can be used for dental rebuilding without tooth facing. The technical result lies in improving the fixation strength of ceramic veneers without tooth facing. This result is achieved in the method of mounting ceramic veneers comprising surface preparation of at least one veneer, surface preparation of at least one tooth and their coupling using light-cured adhesive cement by means of sandblasting of the tooth surface during its preparation with aluminum oxide powder Al2O3, etching by orthophosphoric acid for 15-30 seconds followed by washing and drying, surface treatment with adhesive for 15-20 seconds, application of a bonding agent, and by means of veneer surface etching with hydrofluoric acid during its preparation followed by treatment with a ceramic primer for one minute and application of a bonding agent on the surface.
