A photocurable composition, comprising a photopolymerizable component and a photopolymerization initiator, further comprising a filler wherein: in a case in which a square plate shaped test piece A1 with a length of 10 mm, a width of 10 mm, and a thickness of 2 mm, is produced, at least one square surface B1 having an area of 3 µm on a side in at least one cross section of the test piece A1 has a sea-island structure composed of island portions comprising the filler and having a length of 0.1 µm or more, and a sea portion, an average surface elastic modulus of the island portions is 9.0 GPa or more, an average surface elastic modulus of the sea portion is 4.5 GPa or more, an area of the island portions is from 1.0% to 15.0% with respect to an entire area of the surface B1, and an area of the sea portion is from 85.0% to 99.0% with respect to the entire area of the surface B1.

The invention discloses a light-cured transparent resin composition as well as a preparation method and application thereof. The light-cured transparent resin composition can be applied as a 3D printed piece coating. An existing light-cured resin coating is difficult to completely cure on the surface in air and can yellow, so that the existing light-cured resin coating needs to be used in the environment protected by nitrogen or other inert gases, the resin has the problems of low strength, poor toughness, insufficient moldability and the like, and particularly, the water resistance bottleneck limits the application of the product in the field of 3D printing, especially dental 3D printing pieces. The invention discloses a novel formula, the acrylate monomer, the auxiliary oligomer, the sulfydryl modifier, the photoinitiator, the amine synergist and the nano inorganic filler are mixed to obtain the light-cured transparent resin, the surface glossiness of a 3D printed piece can be improved, the 3D printed piece can be well cured in air, the light-cured resin is prevented from being oxidized to become yellow in the curing process, and the service life of the 3D printed piece is prolonged. And moreover, the biocompatibility of a 3D printing piece is improved, and the product is suitable for preparing a photocuring 3D printing dental product.

The invention relates to a dental product for forming an endodontic cement in a dental canal, said product comprising at least: - propylene glycol in an amount of greater than or equal to 20% by mass, - a mixture of dicalcium phosphate and tetracalcium phosphate capable of forming hydroxyapatite in the presence of moisture, this mixture being present in an amount of between 34% and 40% by mass, - a binder in an amount of between 1% and 4% by mass, - a radiopaque contrast agent made of zirconium oxide in an amount of greater than or equal to 20% by mass, and - potassium citrate in an amount of between 0.1% and 0.38% by mass.

This invention discloses a method for generating a digital balancer based on a 3D tooth model, comprising the following steps: selecting points on the surface of a tooth STL model to obtain an initial point set P1 containing world coordinates; forming a point set P2 through P1; calculating the normal vector of each point, and classifying the points according to the normal vectors of each point in point set P2; performing spectral clustering on each category; using each category point after clustering as a latent function to obtain multiple cut-out surfaces of the tooth STL model; stretching all cut-out surfaces of the tooth STL model and connecting the two surfaces to form a 3D solid model; merging all 3D solid models using Boolean summation to obtain an initial balancer model; obtaining a balancer with cylinders using Boolean difference; and refining the mesh of the balancer with cylinders. This method facilitates dentists in designing other dental products, such as jaw pads, and improves the efficiency of balancer manufacturing while reducing production costs.
