A 3D printed composite metal mesh structure for a removable denture

Abstract

A 3D printing composite metal mesh structure's removable denture, including 3D printing denture base, 3D printing fixedly provided with denture body on the denture base, the molar of the denture body 3D prints a layer of mesh metal structure formed by cobalt-chromium alloy at the cusp and the oblique ridge, and the mesh metal structure and the denture body of the dental fossa form a steel-plastic mixed occlusal surface.The structure of the 3D printing composite metal mesh structure's removable denture is ingeniously arranged, the cusp and the oblique ridge of the molar occlusal surface are 3D printed by cobalt-chromium metal, and the dental fossa is formed by the denture body of the resin, thereby forming a steel-plastic mixed occlusal surface.Due to two different materials, different speeds of abrasion are generated in the mastication process, the abrasion difference makes the resin descend faster, the metal of the cusp and the ridge is relatively high and convex, and the resin of the dental fossa is relatively concave, therefore, the effect of the more mastication, the sharper use is generated, the mastication function is improved, and the service life of the removable denture is prolonged.

Description

Technical Field

[0001] This utility model relates to the technical field of removable dentures, specifically a removable denture with a 3D-printed composite metal mesh structure. Background Technology

[0002] Dentures are artificial teeth replaced with dentures after teeth have been lost or extracted to restore functions such as chewing, aesthetics, and speech. They are divided into fixed dentures and removable dentures. Removable dentures, also known as removable prostheses, include removable partial dentures and complete dentures. They utilize the remaining natural teeth, the mucosa and bone tissue under the denture base for support, and rely on the denture's retainers and base for retention. Artificial teeth restore the shape and function of missing teeth, and the base material restores the morphology of the damaged alveolar ridge, jawbone, and surrounding soft tissues. Patients can remove and insert these prostheses themselves.

[0003] To make dentures more aesthetically pleasing and natural, traditional removable dentures consist of a resin denture body fixed to a denture base. In daily life, our dentures experience physiological wear during chewing. With age, poor chewing habits, and bruxism (teeth grinding) contribute to this increased wear, leading to lower chewing efficiency and greater pressure on the jawbone over time. To reduce the effort required for biting and decrease pressure on the jawbone, new removable dentures need to be custom-made, resulting in a shorter lifespan for traditional removable dentures. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a 3D-printed composite metal mesh structure removable denture. This 3D-printed composite metal mesh structure removable denture features a cleverly designed structure. The occlusal surfaces of the molars are printed with 3D cobalt-chromium metal cusps and ridges, while the dental fissures are made of resin, thus forming a steel-plastic hybrid occlusal surface. Due to the two different materials, they wear at different rates during chewing. This difference in wear causes the resin to wear down faster, while the metal cusps are relatively convex, and the resin fissures are relatively concave. Therefore, it produces a faster wear rate and a sharper feel with continued use, improving chewing function and extending the lifespan of the removable denture.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A 3D-printed removable denture with a composite metal mesh structure includes a 3D-printed denture base, on which a denture body is 3D-printed and fixed. A layer of cobalt-chromium alloy mesh metal structure is 3D-printed along the cusps and oblique ridges of the molars of the denture body. The mesh metal structure and the denture body in the dental pits and grooves form a steel-plastic hybrid occlusal surface. The denture base, denture body, and mesh metal structure are 3D-printed as a single unit.

[0006] A further preferred embodiment: the denture base includes a maxillary denture base and a mandibular denture base, and the mesh metal structure includes a maxillary mesh metal structure and a mandibular mesh metal structure.

[0007] A further preferred embodiment: the denture body fixedly mounted on the 3D-printed base of the maxillary denture includes molars, maxillary canines, and maxillary incisors, which is a maxillary full-mouth removable denture. The maxillary mesh metal structure is fixedly mounted at the cusps and oblique ridges of the maxillary molars and the maxillary second premolars.

[0008] A further preferred embodiment: the maxillary denture base has a mesh framework installed inside the base at the oral cavity palate position.

[0009] A further preferred embodiment: the denture body, which is 3D printed and fixed on the mandibular denture base, includes molars, mandibular canines, and mandibular incisors. In this case, it is a complete mandibular removable denture. The mandibular mesh metal structure is fixed at the cusps and oblique ridges of the mandibular molars and the second mandibular premolars.

[0010] A further preferred embodiment: the bottom of the mesh metal structure is fixedly connected with a post for embedding in the denture body, making the connection between the mesh metal structure and the denture body more secure, and preventing the mesh metal structure from falling off due to wear on the occlusal surface of the denture body, thus affecting the service life of the removable denture.

[0011] This 3D-printed composite metal mesh removable denture features a cobalt-chromium alloy mesh structure 3D-printed along the cusps and ridges of the molars. This mesh structure, along with the denture body in the pits and fissures, forms a steel-plastic hybrid occlusal surface. The metal printing material at the cusps and the resin in the pits have different hardnesses, resulting in different rates of wear during chewing. This difference in wear causes the resin to wear down faster, while the relatively convex metal cusps and concave pits wear down more quickly, creating a "faster and sharper" effect with continued use, thus improving chewing function. Compared to ordinary full dentures, which tend to slow down with use, this removable denture requires less biting force to crush food, reducing pressure on the jawbone and promoting jawbone health. Furthermore, the 3D-printed cobalt-chromium alloy is strong and wear-resistant, offering a 20-year warranty. Attached Figure Description

Example 1

[0016] A removable denture with a 3D-printed composite metal mesh structure includes a 3D-printed denture base, on which a denture body is 3D-printed and fixed. The molars of the denture body have a 3D-printed mesh metal structure formed of cobalt-chromium alloy along the cusps and oblique ridges. The mesh metal structure and the denture body in the dental pit groove constitute a steel-plastic hybrid occlusal surface.

[0017] The denture bases include maxillary denture base 1 and mandibular denture base 7, and the mesh metal structure includes maxillary mesh metal structure 3 and mandibular mesh metal structure 9.

[0018] The denture body, which is 3D printed and fixed on the base 1 of the maxillary denture, includes molars, maxillary canines 5 and maxillary incisors 6. At this time, it is a maxillary full mouth removable denture. The maxillary mesh metal structure 3 is fixed at the cusps and oblique ridges of the maxillary molars 2 and the maxillary second premolars 4.

[0019] The maxillary denture base 1 has a mesh skeleton 11 installed inside the base at the position of the palate in the oral cavity.

[0020] The denture body, which is 3D printed and fixed on the mandibular denture base 7, includes molars, mandibular canines 12 and mandibular incisors 13. At this time, it is a complete mandibular removable denture. The mandibular mesh metal structure 9 is fixed at the cusps and oblique ridges of the mandibular molars 8 and the mandibular second premolars 10. Example 2

[0021] The difference from Embodiment 1 is that the bottom of the mesh metal structure is fixedly connected with a post 14 for embedding in the denture body, which makes the mesh metal structure more firmly connected to the denture body and avoids the mesh metal structure falling off after the occlusal surface of the denture body is worn, thus affecting the service life of the removable denture.
