Description

Technical Field

[0001] The utility model relates to a complete denture, in particular to a complete denture with abutment bridge base. Background Art

[0002] It is common for the elderly to be missing teeth. As life expectancy increases, the number of elderly patients with edentulous jaws and missing edentulous jaws is also increasing. In order to maintain proper chewing, pronunciation, aesthetics and other functions and to maintain physical and mental health, it is very important and necessary to carry out oral rehabilitation as soon as possible. Full dentures, as restorations made for patients with missing teeth, have become an important way for patients with missing teeth to restore chewing and aesthetics. Another prominent problem is that it is inconvenient for elderly patients to see a doctor and their cooperation is poor. If the number of visits can be reduced and the operation can be simplified, it will greatly facilitate doctors and patients.

[0003] Currently, the main method of restoration of edentulous jaws is still full denture restoration. The application of digital technology in the field of full dentures has made them significantly superior to traditional full dentures in terms of aesthetics, suitability, and overall satisfaction. In particular, it has huge advantages in chairside operation time, processing accuracy, and operability.

[0004] Digital processing of full dentures usually uses CNC cutting technology. Clinical studies have shown that compared with traditional full dentures made by traditional methods, full dentures manufactured by personalized CNC cutting have better tissue surface adaptability, excellent mechanical properties and biocompatibility, and better patient satisfaction.

[0005] Currently, traditionally made full dentures often fall off during wear. This is primarily due to the poor fit of the denture surface with the human mouth, resulting in a loose connection. Furthermore, the restoration process is complex and technically challenging, making it difficult for beginners to master. For elderly patients, long waiting times, frequent follow-up visits, and the need for impression-taking procedures contribute to a poor user experience.

[0006] The most common cutting method for digital denture fabrication involves using gum-colored resin discs to cut the denture base and tooth-colored resin discs to cut the denture dentition, followed by bonding and assembly. Limited bonding precision and lack of standardized bonding material selection can lead to significant bonding errors or even failure. Therefore, achieving integrated cutting of the denture base and artificial teeth is essential. Some researchers have used CNC-machined single-color (tooth-colored) resin discs to create integrated complete dentures, which are then dyed with gum-colored light-curing resin. While this method allows for integrated fabrication, post-processing is time-consuming and labor-intensive, and extensive dyeing can cause complications such as denture discoloration. Other researchers have proposed cutting two-color resin discs: using gum-colored resin discs to create the base portion of the integrated complete denture, then cutting back to create a crown-like shape for subsequent bonding, and then using tooth-colored resin discs to create the tooth portion of the integrated complete denture, which is then bonded separately. While this method achieves both digital fabrication and aesthetically pleasing results, it still carries the risk of individual teeth falling out when fully occluded, and individual bonding is time-consuming and labor-intensive.

[0007] Therefore, how to use digital methods to design full dentures more accurately, conveniently and individually, while improving the bonding strength and operability of two-color resin discs and reducing the risk of falling off, has become the problem that this patent intends to solve. Utility Model Content

[0008] The utility model provides a complete denture with abutment bridge base, wherein the complete denture comprises a base and a complete dental arch denture group arranged on the base.

[0009] The base is provided with tooth arrangement slots arranged in a dental arch shape and used to install the full arch denture set. The tooth arrangement slots are composed of a number of tooth installation slots. The roots of the full arch denture set are embedded in the tooth arrangement slots and fixed with glue.

[0010] The base is integrally formed with a dental arch-shaped abutment bridge that runs through the tooth alveoli. The abutment bridge is provided with ribs located in the mounting groove of each tooth.

[0011] The full arch denture set is provided with a clamping groove matched with the convex rib.

[0012] Furthermore, the base is designed digitally and machine-turned to form an integrated base.

[0013] Furthermore, the upper and lower jaw full arch denture groups are respectively set as the maxillary denture group and the mandibular denture group; wherein,

[0014] The maxillary denture set and the mandibular denture set are both one-piece denture sets; or

[0015] The maxillary denture set and / or the mandibular denture set is a multi-segment denture set comprising a plurality of sub-denture sets, and the sub-denture sets are provided with one or more individually designed resin cutting teeth.

[0016] Furthermore, the two central incisors and the two lateral incisors are integrally formed to constitute one of the denture sets.

[0017] Furthermore, the maxillary denture group and the mandibular denture group are digitally designed and machine tools are used to turn them into an integrated maxillary denture group and a segmented mandibular denture group.

[0018] Furthermore, the outer surface of the rib and / or the inner surface of the groove is an uneven rough surface.

[0019] The present utility model proposes an innovative tooth restoration method, which significantly improves the strength of tooth retention by adopting a personalized cutting arch denture group as the upper restoration structure. This method effectively solves the problem of falling off that is easy to occur when using a single resin tooth for traditional tooth arrangement. In the present utility model, the crown of the restoration denture is precisely worn on the abutment and the continuous abutment bridge, and then bonded by adding a special adhesive, thereby greatly enhancing the stability of the denture on the base. This design not only improves the production efficiency of the restoration, but also significantly improves the aesthetics of the restoration, so that patients can have a natural and beautiful appearance while restoring the function of their teeth. Through this technology, patients can enjoy a more comfortable, stable and beautiful tooth restoration experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0026] In order to fully understand the present invention, detailed steps and detailed structures will be provided in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention may also have other implementation methods.

[0027] The utility model provides a complete denture with an abutment bridge base 10 . The complete denture comprises the base 10 and maxillary and mandibular complete arch denture groups arranged on the base 10 .

[0028] The base 10 is provided with arch-shaped tooth sockets 11 for mounting a complete denture set. These sockets 11 consist of several tooth-mounting slots 12. The roots of the complete denture set are embedded in the sockets 11 and secured with glue. The base 10 is integrally formed with an arch-shaped abutment bridge 30 that extends through the sockets 11. This abutment bridge 30 has ribs 31 positioned within each tooth-mounting slot 12. The complete denture set is equipped with retaining slots 23 that mate with the ribs 31. Each tooth in the complete denture set has a retaining slot with an inverted U-shaped opening.

[0029] The slot 23 of the denture group cooperates with the arch-shaped abutment bridge 30 of the base 10. On the one hand, it plays a positioning role and improves the matching accuracy between the denture group and the base. On the other hand, it can improve the stability of the denture, disperse the occlusal force, and reduce the pressure on the abutment.

[0030] In an optional embodiment, the base 10 is digitally designed and machine-turned to form an integrated base 10. In addition, the maxillary denture group 21 and the mandibular denture group 22 are digitally designed and machine-turned to form an integrated maxillary denture group 21 and a segmented mandibular denture group 22.

[0031] The upper and lower jaw denture groups are respectively an upper jaw denture group 21 and a lower jaw denture group 22. In one embodiment, the upper jaw denture group 21 and the lower jaw denture group 22 are both continuously integrally formed crown bridges. In another optional embodiment, the upper jaw denture group 21 is as follows Figure 2 The one-piece denture set shown in the figure is a multi-segment denture set, while the mandibular denture set 22 is a multi-segment denture set comprising a plurality of sub-denture sets 22-1, each of which is provided with one or more individually designed resin cutting teeth. Figure 3-Figure 4As shown, the mandibular denture set 22 is composed of five sub-denture sets 22 - 1 , and two central incisors and two lateral incisors are integrally formed to form the sub-denture set 22 - 1 in the middle of the mandibular denture set 22 .

[0032] In an optional embodiment, the outer surface of the rib 31 and / or the inner surface of the groove 23 are roughened and uneven. This roughened surface significantly enhances the bonding strength when the denture assembly is bonded to the base 10 using an adhesive. The roughened surface increases the contact area, allowing the adhesive to better penetrate and adhere to the rib and groove surfaces, resulting in a more secure bond. Furthermore, this design can, to a certain extent, absorb and disperse the stress generated by the denture assembly during chewing, reducing adhesive failure caused by stress concentration.

[0033] The production process of this utility model is as follows:

[0034] 1. The patient obtains a digital impression (or a physical impression scanned as a digital impression) and jaw position during the first visit;

[0035] 2) Design the digital base and full dental arch using software (such as exocad and 3shape) and export them as recognizable STL files.

[0036] 3) The imported STL file is cut into a base (resin or polyetheretherketone) with a bridge frame using a dental cutting machine, which is then covered in the oral cavity and fixed by adsorption.

[0037] 4) The base 10 with the abutment bridge 30 and the continuous full-arch denture set are designed using digital software, resulting in an STL file that can be read by a lathe. This is then cut separately using a cutting machine to produce the integrally formed upper and lower bases, the integral maxillary denture set 21, and the segmented mandibular denture set 22. The maxillary denture set 21 and mandibular denture set 22 are then bonded to the upper and lower bases 10 containing the abutment bridge 30, completing the restoration.

[0038] The present invention combines existing computer-aided design / manufacturing (CAD / CAM) technology and additive manufacturing materials (resins and polyetheretherketone), and is based on clinical digital modeling and digital technology, personalized design, and precision manufacturing, breaking the traditional perception that conventional full dentures require multiple visits to the doctor, low tightness, difficulty in operation by restoration technicians, high clinical requirements for doctors, and long processing cycles. The digital full denture in the present invention has greatly improved adsorption capacity in the mouth, and a base with abutment bridge and a full-arch crown bridge are designed simultaneously in the design software using two-color materials. It is cut using a dental cutting machine, and the design and cutting process is simple and quick, and the resulting base is not only personalized but also precise. The abutment bridge involved in the present invention guides the crown bridge into position through the adjacent points of the entire dentition, which provides better retention, enhances the bonding strength of the denture, resists the risk of single tooth loss, and improves the efficiency of production and use. In addition, using gum-colored materials to make a base with the shape of the gingival papilla, and using tooth-colored materials to make a matching full-arch crown bridge, the clinical effect is more beautiful than backfilling after single-color cutting.

[0039] The above describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-mentioned disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present invention without departing from the scope of the technical solution of the present invention, or modify them into equivalent embodiments with equivalent changes, which does not affect the essential content of the present invention. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention that do not depart from the content of the technical solution of the present invention are still within the scope of protection of the technical solution of the present invention.
