Description

Technical Field

[0001] The present invention belongs to the technical field of oral medical technology, and in particular relates to a telescopic crown repair denture. Background Art

[0002] Relevant scientists have called for the prevention of cardiovascular diseases to start with the prevention of oral diseases. The general practice is to require patients to keep their teeth clean, ask professional dentists to perform regular oral health maintenance and examinations every six months, and quit smoking and other basic strategies. For patients with severe periodontal disease, they often have serious symptoms such as most tooth loss, loss of chewing function, and temporomandibular joint disorder. The reconstruction of oral occlusal function after thorough periodontal treatment is very important for improving the patient's quality of life. The application of telescopic crowns provides an ideal restorative method for patients who have suffered from missing teeth for a long time and have not received good results with traditional restoration methods, meeting the user's requirements for beauty, comfort and function.

[0003] The second layer of the existing traditional telescopic crown is made by hand, with a rough interior and point contact, which cannot achieve a mirror effect and cannot generate good friction with the first layer, affecting the wearer's comfort.

[0004] Therefore, it is necessary to provide a telescopic crown restoration denture to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a telescopic crown denture and a method of use. By precisely designing the first and second telescopic crowns and increasing the smoothness between the telescopic crowns, the present invention solves the problem that existing telescopic crown dentures are manually manufactured, have rough interiors, and affect the wearer's comfort.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a telescopic crown restoration denture, comprising gums, abutment teeth, a first-layer telescopic crown, a second-layer telescopic crown and a space gap, wherein the abutment teeth are arranged on the top of the gums, the first-layer telescopic crown is fixedly bonded to the side of the abutment teeth, the second-layer telescopic crown is movably connected to the side of the first-layer telescopic crown, and there is a space gap between the first-layer telescopic crown and the second-layer telescopic crown.

[0008] In a preferred embodiment of the present invention, the second-layer telescopic crown is integrally connected to the removable denture, and retention is achieved through friction between the first-layer telescopic crown and the second-layer telescopic crown.

[0009] In a preferred embodiment of the present invention, the inner side surface of the first-layer telescopic crown matches the side of the abutment tooth.

[0010] In a preferred embodiment of the present invention, the precision between the side of the first-layer telescopic crown and the second-layer telescopic crown is ±2um.

[0011] According to a preferred embodiment of the present invention, the side surfaces of the first-layer telescopic crown and the inner side surfaces of the second-layer telescopic crown are both mirror-smooth.

[0012] In a preferred embodiment of the present invention, the first-layer telescopic crown can be made of PEEK material or zirconium dioxide material, and the second-layer telescopic crown is made of PEEK material.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention adopts the design of a first-layer telescopic crown and a second-layer telescopic crown. The inner side surface of the first-layer telescopic crown is designed according to the shape of the side portion of the abutment tooth and is bonded to the side portion of the abutment tooth for fixation. The side portion of the first-layer telescopic crown and the inner side surface of the second-layer telescopic crown are mixed and finely processed to make the side portion of the first-layer telescopic crown and the inner side surface of the second-layer telescopic crown mirror-smooth surfaces. The first layer and the second layer of the telescopic crown generate adsorption force through mirror friction, so that the removable denture is comfortably worn in the patient's mouth, thereby effectively improving the wearer's comfort.

[0015] 2. The present invention uses an optical scanner and a contact scanner to scan the first-layer telescopic crown between the contact surfaces of the first-layer telescopic crown and the second-layer telescopic crown to obtain STL data of the first-layer telescopic crown, and uses EXO design software to design the second-layer telescopic crown based on the data, and uses a 3D laser machine to print the second layer. The printed metal is heat treated to release internal stress, and the finishing tool path is calculated by hyperDENT typesetting software. The calculated tool path is used to finish the inner cage of the second layer of the telescopic crown using a high-precision machine tool Roders. The second layer of the inner cage has a mirror effect, which makes the telescopic crown more surprising, thereby effectively solving the roughness existing in manual manufacturing.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1 , a telescopic crown restoration denture shown in the figure includes gum 1, abutment 2, a first-layer telescopic crown 3, a second-layer telescopic crown 4 and a space 5. The abutment 2 is provided on the top of the gum 1, the first-layer telescopic crown 3 is fixedly bonded to the side of the abutment 2, the second-layer telescopic crown 4 is movably connected to the side of the first-layer telescopic crown 3, and there is a space 5 between the first-layer telescopic crown 3 and the second-layer telescopic crown 4.

[0024] In this embodiment, the second-layer telescopic crown 4 is connected to the removable denture as a whole, and is retained by friction between the first-layer telescopic crown 3 and the second-layer telescopic crown 4. The inner side surface of the first-layer telescopic crown 3 coincides with the side of the abutment 2. The precision between the side of the first-layer telescopic crown 3 and the second-layer telescopic crown 4 is ±2um. The side of the first-layer telescopic crown 3 and the inner side surface of the second-layer telescopic crown 4 are both mirror-smooth. The first-layer telescopic crown 3 can be made of PEEK material or zirconium dioxide material, while the second-layer telescopic crown 3 is made of PEEK material.

[0025] It is applicable to a certain range. By adopting the "optical glue principle", the smoother the contact surface of the two objects, the smaller the friction. When the smoothness of the object surface exceeds a certain limit, the smoother the surface, the greater the friction, so that the molecules of the two overly smooth surfaces are closely adjacent to each other, and the distance between them is very small. The molecules on the two surfaces attract each other due to the electromagnetic effect. At this time, the two objects cannot be separated or move relative to each other. The combined force of the mutual attraction of many molecules on the two contact surfaces is greater than the bonding force of super glue. The first and second layers of the telescopic crown generate adsorption force through mirror friction, which makes the removable dentures comfortably worn in the patient's mouth. High-precision equipment is used, taking advantage of digitalization, and using equipment instead of manual labor to achieve a mirror effect in the second layer of the telescopic crown, thereby changing the friction structure between the telescopic crowns.

[0026] When designing and installing the telescopic crown restoration denture proposed in the present invention, the first-layer telescopic crown 3 is scanned by using an optical scanner + a contact scanner, and the data of the two are combined to obtain the STL data of the first-layer telescopic crown 3. Then, the second-layer telescopic crown 4 is designed using the EXO design software based on the STL data of the first-layer telescopic crown 3. A 3D laser machine is used to print the metal of the second-layer telescopic crown 4. The printed metal is heat-treated to release internal stress. The finishing tool path is calculated using the hyperDENT typesetting software. The calculated tool path is used to finish the inner cage of the second-layer telescopic crown 4 using the high-precision machine tool Roders. The second-layer telescopic crown 4 with a mirror effect of the inner cage is obtained by finishing, and finally good friction is generated between the first-layer telescopic crown 3 and the second-layer telescopic crown 4. This is achieved by bonding the first-layer telescopic crown 3 to the side of the abutment 2 and then movably connecting the second-layer telescopic crown 4 to the side of the first-layer telescopic crown 3.

[0028] Based on the first embodiment, the second embodiment is a further improvement thereof. A telescopic crown restoration denture further includes inclined lines. The inner wall of the first-layer telescopic crown is provided with a plurality of first inclined lines, and the inner wall of the second-layer telescopic crown is provided with a plurality of second inclined lines. The first inclined lines on the inner wall of the first-layer telescopic crown and the second inclined lines on the inner wall of the second-layer telescopic crown are arranged alternately.

[0029] A second groove is provided on the side of the first oblique pattern, and the second groove is adapted to be installed with the second oblique pattern;

[0030] A first groove is provided on the side of the second inclined pattern, and the first groove is adapted to be installed with the first inclined weapon pattern;

[0031] Several inclined lines form mirror-image smooth surfaces, and the first telescopic crown and the second telescopic crown are fixed by the smooth surface and the inclined lines. The inclined lines and the grooves cooperate with each other to enhance the stability of the fixation of the first telescopic crown and the second telescopic crown.
