An artificial tooth element which is insertable into a cavity of a prosthesis base and has an outer part and an inner part. The outer part is the part of the artificial tooth element which is visible in the inserted state. Consequently, the inner part is the part of the artificial tooth element which is not visible in the inserted state. The inner part has a surface which has, at least partially, in particular completely, a defined surface roughness.

A manufacturing method for a prosthetic apparatus for dental purpose according to one aspect of the present invention includes: acquiring scan data of a model that is a reproduction of at least a part of an inside of an oral cavity of a patient; creating shape data of a shaped body for dental purpose on a basis of the scan data; producing a shaped body on a basis of the shape data; covering at least a part of the shaped body and at least a part of a model with film, the shaped body attached to the model; releasing air in a part covered with the film to deform the film and bring the shaped body into close contact with the model; and curing the shaped body in a state where the shaped body is in close contact with the model.

The invention relates to a denture base having a plurality of tooth socket compartments where one or more of the tooth socket compartments comprises a convex surface configured in step-like structure, and one or more prominences on the step-like structure. The invention further relates to a dental prosthesis including the denture base, at least one bonding agent, and a plurality of artificial teeth. Artificial teeth are bonded within tooth socket compartments such that each artificial tooth can rest upon the top of each prominence in the tooth socket compartment, maintaining a predetermined amount of bonding agent between the artificial tooth and the denture base. The denture base and dental prosthesis of the invention can better address the need for easier, more efficient and reliable set-up of artificial teeth in a denture base, and ensuring more consistent and predictable bonding of artificial teeth in a denture base.

The present invention describes a method for the manufacture of dental prostheses where traditional artisanal or purely manual techniques are combined or merged with other more recent ones based on digital design, which comprises obtaining a digital image of the patient's mouth, digitally designing the dental pieces (1) and the gum (4) in a personalized way for each patient, manufacturing both parts separately, mounting them by tonguing-and-grooving and finally treating the prosthesis. Furthermore, the present invention also includes a dental prosthesis that comprises at least one dental piece (1) and a gum, where both are bonded by tonguing-and-grooving means.

Provided is a denture base that includes a base portion; a socket that is demarcated by a step portion from a gingival area of the base portion and to which an artificial tooth is to be attached; and interdental papilla areas of the gingival area, which are positioned at both ends of the socket along a tooth row, wherein, in a state in which the socket is facing upward, a basal surface of the socket has a ridge-shaped socket apex portion configured by a surface that is convex overall, a peripheral area of the basal surface is in mutually continuous abutment with the step portion, and the socket apex portion is positioned at substantially the same height as, or higher than, apex portions of the interdental papilla areas that are seen from a labial side in a state in which the artificial tooth is attached to the socket.

The present inventive concept relates to a method of manufacturing dentures by using a tray cap jig having false teeth fixed unmovably during milling thereof, the tray cap jig, which is depressed, being manufactured according to a rectangular parallelepiped shape or the same shape as the teeth arrangement in an oral cavity set by a dental denture design software of a 3D printer, the method including: manufacturing the tray cap jig of the same shape as the shape of a rectangular parallelepiped container or teeth arrangement in an oral cavity by using the 3D printer; inserting false teeth into a false teeth hole provided in the depressed tray cap jig; and cutting each of roots of the false teeth to a depth set by the dental denture design software after inserting the false teeth into the tray cap jig.

The present inventive concept relates to a method of manufacturing dentures by using a jig, the method including: planting false teeth in a soft jig to expose roots of the false teeth to outside of the soft jig; inserting the soft jig into a hole provided in a hard jig; cutting exposed portions of the false teeth to a depth set by a controller of a milling machine; and inserting the cut false teeth into a false teeth groove of a gum structure.

A prosthetic tooth for a denture comprises a lingual or palatal surface, an opposing vestibular surface, opposing proximal surfaces, an incisal or occlusal surface and an opposing apical surface, wherein a pocket or slot is defined in the apical surface. The pocket or slot makes it easier to determine whether the tooth is positioned correctly when the tooth is aligned with a denture plate and assists with determining whether the tooth has twisted or tilted.

A method for manufacturing a denture includes: preparing an artificial tooth and a denture base with a concave socket; applying an adhesive to the concave socket; and embedding the artificial tooth in the concave socket to which the adhesive is applied. A socket groove is defined on an inner surface defining the concave socket. The socket groove extends from a concave bottom surface of the concave socket facing a basal surface of the artificial tooth to a lingual concave side surface of the concave socket. Embedding the artificial tooth in the concave socket includes: forming a discharge hole to discharge the adhesive, the discharge hole being defined at an end of the socket groove on a lingual outer surface of the denture base; and discharging the adhesive from the discharge hole.
