A dental prosthesis of a dental prosthesis system includes an incurved contact surface that contacts a gingiva. In a first reference cross-sections including first reference lines, a distance between a first point and the dental prosthesis' outer edge on a lingual side satisfies in an incisal portion, where the first point is an intersection of the contact surface and a line connecting a center of a prosthetic tooth and a position that is offset to the lingual side by 3 mm from the prosthetic tooth's base end point, and in a occlusal portion, a distance between a second point and the dental prosthesis' outer edge on the lingual side satisfies, where second point is an intersection of the contact surface and a line connecting a center of a prosthetic tooth and a position that is offset to the lingual side by a/2 from a prosthetic tooth's base end point.

A reinforcement structure for a crown and root tooth restoration includes: a plurality of reinforcement pins having diameters ranging from 0.1 mm to 0.5 mm, an etching canal facilitating access to an infected apex, in the crown and root restoration, a joining element configured to group the plurality of reinforcement pins together so as to form a bundle of pins, the joining element partially covering the length of the reinforcement pins.

A damping dental post key configured to implant a dental root post for restoration of a tooth is described. The dental post key includes a body for handling and a post carrier having a key shape with respect to a head portion of the dental root post. During implantation of the dental post, rotation of the body compresses a set of springs in contact with the post carrier reducing a reaction force to a tooth root. In this way a limited force will be applied and a root fracture can be prevented. Further, the dental post key can be configured to have a fixed movement in a counterclockwise direction to remove the dental post and a free quarter-cycle movement with effort in a clockwise direction.

A dental implant has a hollow shell with outer bio-compatible surface for engaging a soft tissue socket left in gingival tissue after a tooth has been extracted, to promote healing. The shell tapers outwardly from a first to a second perimeter, the second perimeter being asymmetrically scalloped with opposite distal and mesial peaks and opposite lingual and facial valleys between the peaks. A dental implant in the bone socket left after tooth extraction is rigidly connected to a temporary post, the temporary post extending in the shell. The shell engages against the soft tissue socket without gaps and without requiring alignment between the shell and implant axes.

A structural member made at least in part from a fiber reinforced composite material is provided for use in strengthening the crown of an endodontically treated tooth. The structural member can be attached to a post member, such that the structural member and post member, in combination, define a 3D post for reinforcing an endodontically treated tooth.

A root canal fill device and method for manufacturing the same is disclosed. The root canal fill device includes a flexible core member coupled to a rigid post member.
