Abstract
A stratified material (S, S′) for a support part for dental prosthetic element or prosthesis comprising at least one first layer (5) of a fibrous tissue that is hardenable or has been already crosslinked or optionally hardened previously, or impregnated with crosslinked agents or synthetic material is connected at least partially and at least on one side to a second layer (4) of a rigid or soft material, for instance a synthetic material or silicone. The material is moldable and can be adapted specially to the model of a maxillary (1), a duplicate of a maxillary model or a maxillary. In the supporting body including such a stratified material, the second layer (4) is placed on the side facing the maxillary.
Claims19
A stratified material for support parts for dental prostheses and prosthetic elements comprising:
- at least one first support layer of a hardenable or hardened material, which includes fibers of a different length which are impregnated with crosslinking agent(s) and/or with plastic, in braided, crossed or otherwise woven or knitted form to form a fiber fabric;
- and
- a second layer of soft, shapeable material, wherein the first layer is at least partly connected on one side to at least a part of the second layer.
A stratified material for support parts for dental prostheses and prosthetic elements comprising:
- at least one first support layer of an already hardened fiber fabric impregnated with crosslinking agent(s), or plastic, or a fiber composite;
- and
- a second layer of soft, shapeable material, wherein the first layer is at least partly connected on one side to at least a part of the second layer.
A support part for dental prostheses and prosthetic elements comprising, a stratified material which comprises at least one first support layer of a hardenable or hardened material, which includes fibers of a different length which are impregnated with crosslinking agent(s) and/or with plastic, in braided, crossed or otherwise woven or knitted form to form a fiber fabric, and a second layer of soft, shapeable material,
- wherein the first layer is at least partly connected on one side to at least a part of the second layer, and wherein the second layer is arranged on the side which faces the jaw.
A denture, prosthesis or prosthetic element comprising a support part which comprises a stratified material, which comprises at least one first support layer of a hardenable or hardened material, which includes fibers of a different length which are impregnated with crosslinking agent(s) and/or with plastic, in braided, crossed or otherwise woven or knitted form to form a fiber fabric, and a second layer of soft, shapeable material formed as a distance filler,
- wherein the first layer is at least partly connected on one side to at least a part of the second layer, and wherein the second layer is arranged on the side which faces the jaw.
A method for the production of a support part for dental prostheses and prosthetic elements, which support part comprises a stratified material comprising at least one first support layer of a hardenable or hardened material, which includes fibers of a different length which are impregnated with crosslinking agent(s) and/or with plastic, in braided, crossed or otherwise woven or knitted form to form a fiber fabric, and a second layer of soft, shapeable material, wherein the first layer is at least partly connected on one side to at least a part of the second layer, and wherein the second layer is arranged on the side which faces the jaw;
- wherein the method comprises:
- applying the second layer as a spacer or distance filler to a model or duplicate of a model of a jaw or maxillary section or to the jaw itself;
- and
- applying the first layer on the second layer;
- and
- shaping and stabilizing the first layer according to the contours of the model or of the jaw.
A method for the production of a support part for dental prostheses and prosthetic elements comprising a stratified material, which stratified material comprises at least one first support layer of a hardenable or hardened material, which includes fibers of a different length which are impregnated with crosslinking agent(s) and/or with plastic, in braided, crossed or otherwise woven or knitted form to form a fiber fabric, and a second layer of soft, shapeable material, wherein the first layer is connected at least on one side at least partly to the second layer, and wherein the second layer is arranged on the side which faces the jaw,
- wherein the method comprises:
- applying the stratified material to a model or a duplicate of a model of a jaw or maxillary section, or on the jaw itself;
- and
- shaping and stabilizing the stratified material according to the contours of the model or of the jaw.
