Description

Technical Field

[0001] The invention relates to the field of denture moulds, in particular to a machinable full-mouth denture resin disc with a special structure and an external device. Background Art

[0002] The digital full denture diagnosis and treatment model has become mature and perfect, and has been continuously promoted and applied in clinical practice. In the production of digital full dentures, CNC cutting is currently the most mainstream and mature technology. It can cut and produce the designed full denture base or integrated full denture (artificial teeth and base are made in one).

[0003] The current material is a standard resin disc, and its size is determined according to the requirements of the current standard processing equipment and materials. When the standard-sized material (disc) is used for cutting and processing fixed dentures such as crowns, it can be optimized and laid out to maximize the use of materials. The conventional shape of a resin disc is generally circular, such as the resin block for dental cutting disclosed in the utility model with the publication number CN219000635U, which is a disc-shaped structure as a whole; and the volume of a full denture is relatively large, and one resin disc can only process one full denture (maxillary or mandibular), which will result in low material utilization and serious waste.

[0004] This situation is particularly evident when processing lower half full dentures, maxillary dentures without palatal bases, edentulous implant-covered full dentures, and implant transitional dentures. Therefore, it is urgent to design and manufacture a prefabricated resin material structure and corresponding external structure that can meet the dimensional requirements of CNC-made full dentures, high material utilization rate, and high manufacturing efficiency based on the dimensional data of the anterior-posterior and lateral diameters of the edentulous dental arches and the technical requirements of CNC machining, so as to meet and match the requirements of processing equipment and have good practical value. It can save materials and reduce costs; it can also improve processing efficiency through design layout optimization. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a special structure of a machinable complete denture resin disk and an external device that saves materials and improves processing efficiency.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A machinable full denture resin disc with a special structure comprises a resin disc body, wherein the resin disc body is divided into a working area and a supporting area;

[0008] The working area is a half-runway structure with a hollow middle portion, the front portion of the half-runway structure is a curved portion, and the rear portion is an extension portion; the width of the curved portion is greater than the maximum width of various classified dental arches, and the turning angle of the curved portion is greater than the maximum turning angle of various classified dental arches; the extension portion extends along both ends of the curved portion, and the overall length of the curved portion and the extension portion is greater than the maximum length of various classified dental arches;

[0009] The supporting area is a skirt-shaped structure, and the skirt-shaped structure protrudes outward along the surface of the curved portion.

[0010] Furthermore, the single-side width of the runway formed by hollowing out the middle of the working area is greater than the single-side maximum buccal-lingual diameter of the base corresponding to the different classifications of dental arches.

[0011] Furthermore, the outermost contour of the curved surface portion is an arc shape.

[0012] Furthermore, the skirt-like structure is located in the middle of the outer side of the curved surface portion, and the thickness of the skirt-like structure is smaller than the thickness of the curved surface portion.

[0013] Furthermore, the skirt-shaped structure is provided with a plurality of screw holes.

[0014] Furthermore, the machinable full denture resin disk is used for cutting lower half full dentures, maxillary dentures without palatal bases, edentulous jaw implant coverage full dentures and implant transitional dentures.

[0015] The present invention also provides an external device of a machinable full denture resin disc of a special structure as described above, comprising a horseshoe-shaped sheet and a resin disc fixing seat, wherein the horseshoe-shaped sheet matches the shape of the skirt-shaped structure, a mounting hole matching the outer shape of the resin disc body is formed on one side of the resin disc fixing seat, and a supporting edge for supporting the bottom of the skirt-shaped structure is provided in the mounting hole;

[0016] The horseshoe-shaped sheet fixes the skirt-shaped structure to the supporting edge of the resin disk fixing seat through bolts.

[0017] Furthermore, the horseshoe-shaped sheet is evenly distributed with a plurality of screw holes.

[0018] Furthermore, a limiting groove matching the shape of the horseshoe-shaped sheet is provided on the top of the resin disk fixing seat.

[0019] Furthermore, the resin disc fixing seat is installed on processing equipment.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] (1) The machinable full-mouth denture resin disk provided by the present invention is divided into a working area and a supporting area. The working area is set as a semi-runway-shaped structure with a hollow middle portion, which is divided into a curved surface portion and an extension portion. Its size can save raw materials to the greatest extent and improve material utilization while meeting the general requirements of the maximum width, maximum length, and maximum angle of the dental arch of the entire population. In addition, due to the reduction of the material to be cut, the processing efficiency is further improved;

[0022] The support area is used to install the whole resin disc on the processing equipment, and the semi-runway structure is cleverly combined with the arc shape of the processing equipment, and a sandwich structure is fixed by screws to ensure the stability of the full denture resin disc during the cutting process.

[0023] (2) The present invention designs the cuttable lower half denture resin disk and the external device separately, which, on the one hand, meets the size requirements of the processing equipment and does not require redesigning the processing equipment. The special structure of the cuttable full denture resin disk can be used on the original processing equipment by using the external device. The special structure can be used for cutting and manufacturing lower half full dentures, maxillary dentures without palatal bases, edentulous implant-covered full dentures, and implant transitional dentures.

[0024] (3) In the existing solution, the resin disc is a disc-shaped structure. When it is fixed to the external cutting device, it is necessary to clamp the outer side of the entire resin disc. If the disc-shaped structure needs to be adjusted, the clamping structure of the external cutting device also needs to be adjusted accordingly, which affects the product iteration progress;

[0025] The present invention configures the resin disk as a working area of ​​a semi-runway structure, and arranges a skirt-like structure on the curved surface of the semi-runway structure as a supporting area. The external device only needs to be connected to the skirt-like structure to form a sandwich structure, so that the entire resin disk can be installed and fixed. During the iterative optimization process of the working area of ​​the resin disk, the same external device can be used to fix the skirt-like structure. There is no need to replace the external device, which is more convenient for product iteration and greatly increases the continuity of the development of complete denture CNC cutting technology.

[0037] The working area 11 is a semi-runway type structure with a hollow middle portion, the front portion of the semi-runway type structure is a curved portion 111, and the rear portion is an extension portion 112; the extension portion 112 extends along both ends of the curved portion 111, the width of the curved portion 111 is greater than the maximum width of various classified dental arches, the turning angle of the curved portion 111 is greater than the maximum turning angle of the dental arches of various classified dental arches, and the overall length of the curved portion 111 and the extension portion 112 is greater than the maximum length of various classified dental arches; among them, various classified dental arches are generally divided into square round, oval and pointed round types, and the above-mentioned structure setting needs to be comprehensively considered with respect to the maximum width, maximum turning angle and maximum length of each type of dental arch.

[0038] The supporting area 12 is a skirt-like structure that protrudes outward along the surface of the curved surface portion 111 .

[0039] Preferably, in the working area 11, the width of the contour of the working area 11 is determined according to the maximum extension range of the base corresponding to the different classifications of dental arches, that is, the single-side width d of the runway formed by the hollowing out of the middle of the working area 11 is greater than the single-side maximum buccolingual diameter of the base corresponding to the different classifications of dental arches.

[0040] Structural principle:

[0041] This solution takes into account that the human dental arch shapes include square, oval and pointed, with different curvatures and radii, and the middle part is generally a through-hole structure, so the front part of the working area 11 is determined according to the maximum width of various classified dental arches and the maximum angle of the dental arch turning angle, and the rear part of the working area 11 is designed with an extension part 112 according to the maximum length of various classified dental arches, with a partial reserved length; and then the width of the contour of the working area 11 is determined according to the maximum extension range of the base corresponding to the different classified dental arches.

[0042] Ultimately, the goal of saving materials to the maximum extent possible is achieved while meeting the requirements of the maximum width, maximum length, and maximum angle of dental arch rotation for all people;

[0043] In addition, the problem of how to fix the working area 11 to the external device is also taken into consideration. This solution designs the resin disk support area 12 and the external structure based on the original structure of the cutting machine. The support area 12 is designed to be a skirt-like structure protruding outward along the surface of the curved portion 111, which facilitates installation and fixation with the processing equipment.

[0044] Specifically, the outermost contour of the curved surface portion 111 is arc-shaped, preferably semicircular, and may also be other special curved shapes.

[0045] Preferably, the front part of the working area 11 is determined according to the maximum width of various classified dental arches and the maximum angle of the dental arch rotation, and a partial reserved range is also added. The rear part of the working area 11 is designed according to the maximum length of various classified dental arches, and the extension part 112 is divided and a partial reserved length is also added to improve the versatility of the resin tray.

[0046] Preferably, the skirt-like structure is located in the middle of the outer side of the curved surface portion 111 , the thickness of the skirt-like structure is smaller than the thickness of the curved surface portion 111 , and the radius is larger than the radius of the working area 11 .

[0047] Optionally, the skirt-shaped structure is distributed with a plurality of screw holes and can be fixed to the processing equipment by bolts 4 .

[0051] Equivalently, the new cuttable lower half denture resin disc can be fixed between the horseshoe-shaped sheet 2 and the resin disc fixing seat 3 via screw retention, so as to be installed on the processing equipment to ensure the stability of the cutting process.

[0052] The horseshoe-shaped sheet 2 covers the upper surface of the skirt-shaped structure, and the supporting edge 301 of the resin disk fixing seat 3 is supported on the lower surface of the skirt-shaped structure; the bolt 4 can be connected to the resin disk fixing seat 3 through the horseshoe-shaped sheet 2 and the skirt-shaped structure in sequence, or it can be connected to the resin disk fixing seat 3 directly through the horseshoe-shaped sheet 2 without passing through the skirt-shaped structure, that is, the skirt-shaped structure is fixed by the clamping force between the horseshoe-shaped sheet 2 and the resin disk fixing seat 3.

[0053] Optionally, the horseshoe-shaped sheet 2 is evenly distributed with a plurality of screw holes. In this embodiment, three screw holes are provided, which are respectively located at the two ends and the middle of the horseshoe-shaped sheet 2 .
