[0046] In the present disclosure, the term wire relates to both to metal wires and nonmetal wires, and the lightweight durable monolithic bend-resistant dental prosthesis can be also referred to as a wire mesh composite prosthesis

[0047] The provided lightweight durable monolithic bend-resistant dental prosthesis is used for restoration of all types of teeth with damages 2 mm above a gumline, at a gumline and/or below a gumline. As it is known, different types of teeth have different number of roots, which depends on a shape, and position of a tooth in an oral cavity. For example, incisors and canines usually have a single root, premolars usually have one or two roots, and molars usually have roots in the quantity of three to four. The provided lightweight durable monolithic bend-resistant dental prosthesis can be implemented for a direct dental restoration (the dental prosthesis is formed directly in an oral cavity) or for an indirect dental restoration (the dental prosthesis is formed outside an oral cavity).

[0048] A lightweight durable monolithic bend-resistant dental prosthesis intended for restoring a tooth according to the first aspect of the present invention comprises a double coronal-root reinforcing supporting part and a dental restorative material part.

[0063] Some embodiments of the lightweight durable monolithic bend-resistant dental prosthesis intended for restoring a tooth according to the fist aspect of the present invention are illustrated below by way of examples.

EXAMPLE 1

[0064] The lightweight durable monolithic bend-resistant dental prosthesis 100 according to example 1 is illustrated in FIGS. 1-4 and is, intended to restore/reconstruct an incisor and comprises a double coronal-root reinforcing supporting part 140 and a dental restorative material part 130. FIGS. 4a, 4b show a side view and a front view of the dental prosthesis 100. In this example, the dental restorative material part 130 comprises a composite material, however, in other examples it can comprise compomer material and/or others dental restorative materials. The dental prosthesis 100 has a root part, also known as a truncated conical cavity of the dental prosthesis, and a coronal part, which correspond to similar anatomical parts of a tooth to be restored, i.e. a root and coronal parts of the tooth to be restored.

[0065] The double coronal-root reinforcing supporting part 140 (FIGS. 3a, 3b show a side view and a front view of the double coronal-root reinforcing supporting part 140) of the dental prosthesis 100 consists of two parts which are a flexible fan-shaped frame 110 having a root part and a coronal part and a mesh coronal-root frame 120 having a root pert and a coronal part. The dental restorative material part 130 encapsulates only the coronal parts of the fan-shaped frame 110 and the mesh coronal-root frame 120. In this example, the fan-shaped frame 110 and the mesh coronal-root frame 120 relate both to the root part and the coronal part of the dental prosthesis. It is important to note that the lightweight durable monolithic bend-resistant dental prosthesis in other examples can have more than one fan-shaped frame, and their amount generally depends on the number of roots of a tooth to be restored.

[0066] The flexibility of both parts of the double coronal-root reinforcing supporting part increases adaptive properties and customization of the claimed prosthesis and, as a result, increases its load-bearing properties. The mobility and flexibility of both parts of the double coronal-root reinforcing supporting part also allows implementing variety of designs of the future prosthesis, determining universality of the claimed prosthesis.

[0067] It is to note that in other embodiments fan-shaped frames and mesh frames can be implemented as not flexible frames, i.e. as rigid frames.

[0068] Returning to the parts of the double coronal-root reinforcing supporting part in this example, the fan-shaped frame 110 (FIGS. 1a, 1b show a side view and a front view of the fan-shaped frame 110) has an elongated form and comprises a plurality of wires 115 taken as a strand of wires. The fan-shaped frame 110 has an apical part 111 and a main part 112 wider than the apical part 111 in one plane, which means that the wires 115 are positioned in the fan-shaped frame 110 in such way that they form a fan shape substantially in one plane. The apical part 111 is the root part of the fan-shaped frame 110, meaning that the apical part 111 of the fan-shaped frame 110 relates to the root of a tooth to be restored, and the main part 112 is the coronal part of the fan-shaped frame 110.

[0069] In some embodiments, the main part of the fan-shaped frame can also relate only to the, coronal part of the dental prosthesis, or both to the root part and, to the coronal part of the dental prosthesis, as partly described by the description of the configuration of the expanding frames given above.

[0070] According to this example of the prosthesis 100, the wires 115 of the fan-shaped frame 110 are crimped metal wires which are U-bent in the middle such that bent ends 117 of the wires 115 are located at a distance from each other and define a fan shape of the main part 112 of the fan-shaped frame 110. Further, the bent ends 117 of the wires 115 are located in the coronal part of the dental prosthesis 100 in the direction of masticatory surface or a cutting edge of the coronal part, while free ends of the wires 115, which are opposite to the bent parts 117 of these wires, are twisted together and define the apical part 111 of the fan-shaped frame 110. In this example, the bent ends 117 of the wires 115 are positioned in 2-2.5 mm from a cutting edge of the dental prosthesis 100 (a so-called top of the coronal part). It is to note that use of crimped wires provides that the wires 115 do not move in relation to each other meaning that the double coronal-root reinforcing supporting part 140 has a necessary stability in its construction.

[0071] It is to note that in other examples the bent ends of the wires of the fan-shaped frame can be located in the root part of the dental prosthesis instead of the coronal part.

[0072] The main part 112 of the fan-shaped frame 110 has a fan shape forming an angle between 5 degrees and 85 degrees depending on anatomy of a tooth to be restored. Further, the wires 115 of the fan-shaped frame 110 in its main part 112 are positioned at the same angle with respect to each other. It is to note that in some examples the wires of the fan-shaped frame can be positioned in its main part at different angles with respect to each other which can be necessary depending on a tooth to be restored and/or for providing additional strength characteristics to the dental prosthesis 100. It is to note, that in some examples of the claimed dental prosthesis intended for restoring molars and premolars, angles between the wires of the fan-shaped frame can change after arranging the dental prosthesis in a correspondent place in an oral cavity with the purpose of restoring a tooth.

[0073] It is to note that in other examples not all wires of the fan-shaped frame can represent crimped wires, and the wires may represent non-metal wires or a combination of metal wires and non-metal wires. In some examples, at least some of the wires have metal parts and non-metal parts. Also, in some examples, at least part of the wires of the fan-shaped frame represent gold-plated wires.

[0074] Returning to the described example, the mesh coronal-root frame 120 (FIGS. 2a, 2b show a side view and a front view of the fan-shaped frame 110) of the double coronal-root reinforcing supporting part 140 is manufactured from a metal mesh 125 and has a configuration depending on a kind of a tooth to be restored. It should be noted that in other examples the mesh coronal-root frame can be partially of fully manufactured from a non-metal mesh. In this examples, since the dental prosthesis 100 is intended to restore an incisor, the mesh coronal-root frame 120 can have a form representing a convex bottom narrow apical part 121 having an apical hole, which relates to a precervical section of the incisor, and the convex bottom narrow apical part 121 continues with a side part 122 resembling one of the side walls of the incisor. The convex bottom narrow apical part 121 is the root part of the mesh coronal-root frame 120, and the side part 122 is the coronal part of the mesh coronal-root frame 120. Such construction of the dental prosthesis means that the mesh coronal root frame 120 in the claimed dental prosthesis 100 is positioned not only below a gumline of the restored tooth, i.e. in the root part, but also above it, i.e. in the coronal part, and thus the dental prosthesis 100 reinforce the most dangerous part in terms of possibility of occurrence of fractures, which is a transition part from the root part to the coronal part. In the claimed dental prosthesis 100, there is no need to have any additional elements for the double coronal-root reinforcing supporting part 140 to connect it with hard tissues of the tooth to be restored.

[0075] In some examples, at least part of the mesh coronal-root frame comprises a gold-plated mesh, which provides, among other things, better aesthetics characteristics of the dental prosthesis. In other examples, at least part of the mesh coronal-root frame comprises a woven mesh made from crimped wires. The woven mesh provides capability of forming such mesh in any suitable form and a stable structure of the mesh.

[0076] The fan-shaped frame 110 passes through the apical hole of the mesh coronal-root frame 120, and the convex bottom narrow apical part 121 of the mesh coronal-root frame 120 surrounds the apical part 111 of the fan-shaped frame 110. Optionally, ends of the wires 115 of the fan-shaped frame 110 are pressed against an inner surface of the mesh coronal-root frame 120.

[0077] Thus, in this example, the double coronal-root reinforcing supporting part 140 of the dental prosthesis 100 represents the fan-shaped frame 110 and the mesh coronal-root frame 120 which are aligned in the longitudinal direction of the dental prosthesis 100 and located in both the root and coronal part of the dental prosthesis. The dental prosthesis 100 at one of its ends relating to its root part has the apical part 111 of fan-shaped frame 110 and at another end the dental prosthesis 100 has a surface of the dental restorative material part 130 which encapsulates a part of the mesh coronal-root frame 120 and a part of the fan-shaped frame 110 and forms the coronal part of the dental prosthesis. Shapes and dimensions of the fan-shaped frame 110 and the mesh coronal-root frame 120 are conditioned by a tooth to be restored by the dental prosthesis 100 and may vary. It is important to note that a dental restorative material in the dental restorative material part 130 can polymerize.

[0078] In the claimed dental prosthesis 100, the coronal part is reinforced riot only with the mesh coronal-root frame 120, but also with the fan-shaped frame 110 to further increase the static-bending strength of the coronal part of the dental prosthesis 100. Further, considering that a root base in the dental prosthesis 100 is reinforced not only with the mesh coronal-root frame 120, but additionally with the fan-shaped frame 110, this eliminates possibility of fractures in the root base region, prevents rotation of the dental prosthesis 100 and improves fixation of the dental prosthesis 100. The above advantages of the claimed dental prosthesis 100 provide a uniform distribution of stress under functional loads on preserved solid tissues of a tooth root, eliminate occurrence of local stress on preserved solid tissues of a tooth root under functional loads and eliminate possibility of cracks and fractures of the walls of the truncated conical cavity in the claimed dental prosthesis 100.

[0079] Approximal walls of the mesh coronal-root frame 120 located in the coronal part are bent at, right angles to each other on a part from a cervical edge (between the root part and the coronal part) to a cutting edge (top of the coronal part) of the dental prosthesis 100, which subsequently, increases the static-bending strength of the coronal part of the restored tooth. After fitting and correction, a width of the formed approximal walls is 2.5-3 mm in the cervical edge region, 2 mm in the middle third region, and 1-1.5 mm in the cutting-edge region.

[0080] It is important to note that for some embodiments of the dental prosthesis intended for restoration of molars and premolars, ends of wires of each fan-shaped frame in its main part may be located at an equator level of the coronal part of the dental prosthesis. Further, in some embodiments, edges of the mesh coronal-root frame are bent outwards or inwards which prevents appearance of tooth marginal fissures.

EXAMPEL 2

[0081] The lightweight durable monolithic bend-resistant dental prosthesis 200 according to example 2 is illustrated in FIGS. 5-8 and is intended for restoration a premolar with one root. This dental prosthesis 200 differs from the, dental prosthesis 100 of the examples 1 described above in that its mesh coronal-root frame 220 (FIG. 6) has an elongated convex form narrowing towards a root part of the dental prosthesis 200. The mesh coronal-root frame 220 is made of a metal mesh 225 and comprises a root part 221 and a coronal part 222.

[0082] Also, the construction of the fan-shaped frame 210 (FIG. 5) is different in that its wires 215 are U-bent in the middle such that bent ends of the wires 215 are twisted together and define an apical part 211 of the fan-shaped frame 210, while free ends 217 of the wires 215, opposite to the bent parts, are located at a distance from each other, so as to form a fan shape, and define the main part 212 of the fan-shaped frame 210.

[0083] The double coronal-root reinforcing supporting part 240 consisting of the mesh coronal-root frame 220 and the fan-shaped frame 210 is shown in FIG. 7, and the dental prosthesis 200 is shown in FIG. 8 in which a dental restorative material part 230 is shown with its cervical margin 235.

In this example, the mesh coronal-root frame has an elongated convex form narrowing towards the root part of the dental prosthesis and having three root parts, which enter three roots of the molar to be restored arid correspond to them. Each of the three root parts has an apical hole. Further, this dental prosthesis has three flexible fan-shaped frames each passing through the apical hole in one of the three arms of the mesh coronal-root frame.
