Description

Technical Field

[0001] This utility model relates to the field of implant technology, and in particular to an artificial dental implant. Background Technology

[0002] In the current field of oral healthcare, titanium or titanium alloys are often used as materials for dental implants. These materials are essentially metals, and while they possess advantages such as strength and stability, they also present significant challenges over time. Due to the unique and complex physiological environment of the human body, titanium or titanium alloys, as foreign metallic substances, may be recognized as "foreign objects" by the immune system when in contact with human tissue for extended periods, leading to a rejection reaction. This rejection reaction can negatively impact the use of dental implants, potentially causing inflammation and loosening around the implant, resulting in an unstable bond between the implant and surrounding tissues. Ultimately, this significantly affects the normal lifespan of the dental implant, causing considerable inconvenience and distress for patients. Therefore, improvements are needed to address these issues. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-4This invention relates to an artificial dental implant, comprising a main body 1, a hydroxyapatite coating 2 at the lower end of the main body 1, a root body 3 at the lower end of the hydroxyapatite coating 2, and an installation groove 4 in the middle of the top surface of the main body 1. The main body 1 facilitates the installation of a connecting block 5 and a sleeve 6. The hydroxyapatite coating 2 facilitates faster fusion of the sleeve 6 and the root body 3 with new tissue. The root body 3 facilitates the installation of a positioning block 7. The installation groove 4 facilitates the installation of a positioning bolt 9. A connecting block 5 is fixedly connected to the middle of the bottom surface of the main body 1, and a sleeve 6 is fixedly connected to the bottom surface of the main body 1. The connecting block 5 is placed inside the sleeve 6, and the outer side of the connecting block 5 abuts against the inner wall of the sleeve 6. The connecting block 5 facilitates the installation of an L-shaped positioning plate 8. The sleeve 6 facilitates the adsorption of the hydroxyapatite coating 2. The hydroxyapatite coating 2 abuts against the outer surface of the sleeve 6, and the bottom surface of the sleeve 6 abuts against the top surface of the root body 3.

[0019] In this invention, a positioning block 7 is fixedly connected to the center of the top surface of the root body 3. The outer side of the positioning block 7 abuts against the inner wall of the sleeve 6, and the top surface of the positioning block 7 abuts against the bottom surface of the connecting block 5. The positioning block 7 facilitates the connection of the positioning bolt 9. A positioning groove is formed on the top surface of the positioning block 7. The positioning groove has an inverted T-shaped cross-section, and multiple equidistant L-shaped positioning plates 8 are engaged inside the positioning groove. The upper ends of the multiple L-shaped positioning plates 8 are fixed to the periphery of the bottom surface of the connecting block 5. The positioning groove facilitates the engagement of the L-shaped positioning plates 8. The L-shaped positioning plates 8 facilitate the positioning of the connecting block 5.
