Description

Technical Field

[0001] This utility model relates to a polyetheretherketone (PEEK) dental prosthesis framework, belonging to the field of dental prosthesis technology. Background Technology

[0002] Dentures are what people commonly call "false teeth." Just as "prosthetic legs" or "prosthetic limbs" are called "prosthetics," "dentures" refer to teeth that fulfill their "duties" for humans. In medicine, they are a general term for restorations made after partial or complete loss of the upper and lower jaw teeth.

[0003] Current implant-supported prostheses often use zirconia bonding in the upper part. Zirconia has a certain degree of transparency, which can easily lead to metallic sheen when the abutment tooth is metallic. Similarly, metal framework interfaces are used at the gum line, and in cases of thin gums, black showing through can negatively impact a patient's self-confidence. Current products use a combination of metal frameworks and zirconia crowns. This type of product lacks ergonomics; during chewing, increased biting forces without cushioning make it prone to chipping when subjected to occlusal interference. Chipped porcelain ages faster, resulting in a shorter lifespan. Pure titanium frameworks, due to the need to maintain interface toughness and strength, cannot undergo high-temperature sintering. The gingival portion of the framework uses polymer porcelain, but the bonding strength between polymer porcelain and metal is relatively low. This makes them prone to aging and falling out after 1-2 years of wear.

[0004] Therefore, it is necessary to design a denture framework that ensures the denture does not show color bleeding or chipping during use, and guarantees the toughness and strength of the interface. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a polyetheretherketone (PEEK) framework, which solves the problems of color bleeding, porcelain chipping, and insufficient toughness and strength of the interface in dentures during use.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: a polyetheretherketone (PEEK) denture framework, comprising...

[0007] Framework, titanium tube, zirconia crown, gingival region;

[0008] The bottom of the bracket covers the gingival portion, the bottom of the bracket is provided with the titanium cylinder, and the top of the bracket can fix the zirconia crown;

[0009] The support structure is integrally formed. The bottom of the support has multiple titanium cylinders with internal threads. The support has an upwardly protruding boss. The zirconia crown has a groove inside. The support can cooperate with the zirconia crown to fix the zirconia crown on the support. The gingival portion is located at the bottom of the support and covers the titanium cylinders.

[0010] The scaffold material is polyetheretherketone.

[0011] Preferably, the color of the gingival region is similar to that of the gums.

[0012] Preferably, the surface of the titanium cylinder is coated with polyetheretherketone.

[0013] Preferably, the support is bonded to the zirconia crown using adhesive.

[0014] Preferably, the support is provided with a plurality of protrusions, and a plurality of zirconia crowns are fixed on the support.

[0015] Preferably, the gingival region is made of polymeric ceramic material.

[0016] Preferably, the bracket is machined using CAM.

[0017] The beneficial effects of this utility model are:

[0018] (1) This invention uses polyetheretherketone (PEEK) in the dental framework, replacing the traditional pure titanium framework. PEEK is milky white, preventing metallic sheen from showing through the crown and resulting in a natural and aesthetically pleasing appearance after restoration. The PEEK coating on the titanium cylinder eliminates the blackening phenomenon caused by thin gingiva in traditional metal frameworks, thus optimizing the visual effect of the transition area between the restoration and the gingiva.

[0019] (2) Through this utility model, the framework of the denture adopts an integral molding structure. The framework material is polyetheretherketone (PEEK), which has high toughness and can buffer the patient's biting force, preventing porcelain chipping due to excessive biting force and extending the service life of the crown. The combination of PEEK material and titanium cylinder, utilizing the rigidity of the titanium cylinder and the toughness of PEEK, can improve the connection stability between the framework and the patient's oral cavity, ensuring the reliability of the implant in long-term use. PEEK has good compatibility with resin. After PEEK is combined with the resin surface simulating the gingiva, it can ensure the long-term stability of the gingival portion and extend the overall service life of the restoration.

[0020] (3) Through this utility model, the stent adopts CAM processing in the production process. CAM can also process pure titanium stents. The stent adopts CAM to process polyether ether ketone in the production process, which can make the stent without adding additional processing equipment, reducing manufacturing costs and technical implementation difficulties.

[0026] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1

[0028] like Figures 1-4 As shown, a polyetheretherketone (PEEK) dental framework includes a framework 1, a titanium cylinder 2, a zirconia crown 3, and a gingival portion 4.

[0029] The base of the framework 1 covers the gingival portion 4, the base of the framework 1 is provided with a titanium cylinder 2, and the top of the framework 1 can fix the zirconia crown 3.

[0030] Reference Figures 1-4 The framework 1 is a one-piece molded structure. Multiple titanium cylinders 2 are threaded through the bottom of the framework 1. The framework 1 has multiple upward-protruding bosses. Multiple grooves are formed inside the zirconia crown 3, allowing the crown to engage with the bosses on the surface of the framework 1, thus securing the crown to the framework 1. The gingival portion 4 is fixed to the bottom of the framework 1 and covers the titanium cylinders 2. The framework 1 is made of polyetheretherketone (PEEK).

[0031] Reference Figure 1 , Figure 2The gingival portion 4 fills the bottom of the framework 1. The color of the gingival portion 4 is similar to that of the gum line, used to improve the overall appearance and aesthetics of the prosthesis framework. By placing the gingival portion on the outside of the framework 1, the color of the framework 1 and the titanium cylinder 2 can be concealed, avoiding abrupt or blackish discoloration at the gum line, thus making the overall appearance of the restoration more aesthetically pleasing. The gingival portion 4, covering the bottom of the framework 1, provides some isolation, reducing metal irritation to surrounding tissues and preventing discomfort or inflammation in the oral cavity. The gingival portion 4 has a certain degree of resilience, reducing impact during chewing and minimizing stress on the framework 1 and titanium cylinder 2, extending the overall lifespan of the prosthesis framework. It also has a sealing function, preventing saliva and bacteria from entering the gap between the framework 1 and the titanium cylinder 2, reducing the risk of infection and protecting the patient's oral health. Furthermore, the shape of the gingival portion 4 supports the soft tissue of the gums, maintaining the normal shape of the gums and preventing soft tissue collapse or atrophy.

[0032] Reference Figure 3 , Figure 4 The surface of the titanium tube 2 is covered with polyetheretherketone (PEEK). PEEK can block the original color of the titanium tube 1. When the denture framework is installed inside the patient's mouth, the PEEK covering the surface of the titanium tube 2 can prevent the titanium tube 2 from showing through.

[0033] Reference Figure 3 , Figure 4 The top of the framework 1 has a number of protrusions, each positioned at the center of the patient's denture. The zirconia crown 3 has internal grooves, the shape of which corresponds to the protrusions. The shape of the zirconia crown 3 is identical to that of a normal tooth, and it is glued to the top groove of the framework 1. The shape of the zirconia crown 3 conforms to the shape of the patient's dentition, ensuring that the denture with the zirconia crown 3 matches the shape and arrangement of normal teeth when installed in the patient's mouth.

[0034] A bolt is implanted inside the patient's mouth. The titanium cylinder 2 has threads in the middle. The denture framework is fixed inside the patient's mouth by engaging with the bolt inside the patient's mouth through the internal threaded hole of the titanium copper.

[0035] In this embodiment, the gingival portion 4 is made of polymer ceramic material. The framework 1 is fabricated using CAM (Computer-Aided Design) machining. In existing technologies, denture frameworks are machined from pure titanium, mimicking the shape of the patient's abutment teeth. Pure titanium is also machined using CAM. In this embodiment, the fabrication method of framework 1 is the same as in existing technologies, which reduces production costs. The interface of framework 1 connects to the screw-retaining abutment of the implant in the patient's mouth. The interface connection uses a more rigid and stable titanium cylinder 2, which solves the material toughness problem. By replacing the material of framework 1 with polyetheretherketone (PEEK), some occlusal forces can be buffered, thus extending the lifespan of the crown.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
