[0034] Dental implant is a common method of tooth restoration, used to replace missing teeth. During the dental implant process, the dentist will implant an artificial tooth root (generally called an implant) into the alveolar bone, and then install the artificial crown onto the implant through the abutment. Generally speaking, the artificial crown will be customized after the implant is implanted into the alveolar bone. Before the customization is completed, after the dentist connects the abutment to the implant, a protective cap is needed to cover and protect the abutment to prevent damage to the abutment during biting, which would affect the final installation of the artificial crown.

[0035] In the related art, in order to fix the protective cap and the base, a countersunk hole is opened on the protective cap, and the screw rod of the screw passes through the countersunk hole and is screwed to the base to lock the protective cap and the base. However, in actual use, due to the small size of the screw, during the dental surgery, the screw may fall into the patient's mouth and cause a medical accident.

[0036] In order to solve the above problems, the utility model proposes a base protection cap, which aims to reduce the risk of medical accidents. Figure 1 to Figure 2 This is an embodiment of the base platform protection cap provided by the utility model.

[0037] Please refer to Figure 1 to Figure 2 The utility model proposes a base protection cap 1000, which is used to cover a connecting boss 42 arranged on a base 4, the connecting boss 42 is provided with a mounting hole 421, and the inner peripheral wall of the mounting hole 421 is formed with an internal thread. The base protection cap 1000 includes a cap body 1 and a connecting rod 2, the cap body 1 is formed with a accommodating cavity with an opening; the connecting rod 2 is arranged on the bottom wall of the accommodating cavity facing the opening, and the outer peripheral wall of the connecting rod 2 is provided with an external thread, which is used to be threadedly matched with the internal thread of the base 4.

[0038] The material of the base protection cap 1000 is consistent with that of the base 4, which is generally a titanium alloy. Titanium has good biocompatibility and stability, can ensure oral health, and has high strength and durability, and can be used for a long time in the oral environment.

[0039] In this embodiment, a connecting rod 2 is provided in the accommodating cavity, and the outer wall of the connecting rod 2 has an external thread, so that the abutment protection cap 1000 can be directly screwed and locked with the abutment 4, and there is no need to use additional screws to fix the abutment protection cap 1000 and the abutment 4, thereby avoiding the situation in which the screws fall into the patient's mouth during the dental surgery and cause medical accidents.

[0040] Further, in one embodiment of the present invention, please refer to Figure 1 The connecting rod 2 and the cap body 1 are an integrally formed structure. If the connecting rod 2 and the cap body 1 are plug-connected or adhesively connected, the connecting rod 2 may still be separated from the cap body 1 and fall into the patient's mouth during actual use, causing a medical accident. For this reason, the connecting rod 2 and the cap body 1 are designed as an integrally formed structure to completely avoid the situation where the connecting rod 2 is separated from the cap body 1 and falls into the patient's mouth.

[0041] In order to facilitate the use of dentists, in one embodiment of the present invention, please refer to Figure 2 A keyway 11 is formed at one end of the cap body 1 away from the opening. The cross-sectional shape of the keyway 11 is a regular polygon, which can be a square, a regular hexagon, a regular octagon, etc. A socket wrench adapted to the keyway 11 is selected accordingly. The socket wrench and the keyway 11 cooperate to apply torque to the cap body 1, thereby driving the connecting rod 2 to rotate, so that the connecting rod 2 can be screwed into or out of the mounting hole 421 of the connecting boss 42 through the cooperation of the external thread and the internal thread.

[0042] It is understandable that the connecting boss 42 of the base 4 for mounting the artificial crown is generally designed to be truncated cone-shaped, which helps to ensure a firm connection between the artificial crown and the base 4, and also helps to provide better stability and sealing, thereby ensuring the normal function of the artificial crown during chewing and speaking. In order to adapt to the shape of the connecting boss 42, in one embodiment of the utility model, please refer to Figure 1 A base matching slope 12 is formed on the side wall of the base accommodating cavity near the opening end, and the base matching slope 12 is gradually contracted from the end away from the bottom wall of the accommodating cavity to the end close to the bottom wall of the accommodating cavity. In actual use, the base matching slope 12 can be tightly matched with the connecting boss 42, so that the base protection cap 1000 has a good clamping force, which can prevent the base protection cap 1000 from loosening and falling off.

[0043] Further, in one embodiment of the present invention, please refer to Figure 2An arched transition surface 14 is formed at the connection between the end face of the cap body 1 away from the opening and the outer wall of the cap body 1. After the abutment protection cap 1000 is covered on the connecting boss 42 of the abutment 4, the end of the cap body 1 away from the opening will contact the gums. By designing the connection between the end face of the cap body 1 away from the opening and the outer wall of the cap body 1 to be arched, the fit between the gums and the abutment protection cap 1000 can be improved to prevent gum damage.

[0044] Please refer to Figures 3 to 5 The utility model also proposes an implant assembly 2000, which includes an implant 3, an abutment 4 and an abutment protection cap 1000; the implant 3 is formed with a conical mounting groove; the abutment 4 includes an abutment body 41 and a connecting boss 42, a part of the structure of the abutment body 41 is inserted into the conical mounting groove, and abuts against the side wall of the conical mounting groove for limiting position, an end of the abutment body 41 away from the implant 3 is provided with a connecting boss 42, and an end of the connecting boss 42 away from the abutment body 41 is provided with a mounting hole 421, and the mounting hole 4 The inner wall of 21 is formed with an internal thread; the base protection cap 1000 includes a cap body 1 and a connecting rod 2, the cap body 1 is formed with a accommodating cavity with an opening; the connecting rod 2 is arranged on the bottom wall of the accommodating cavity facing the opening, and the outer peripheral wall of the connecting rod 2 is provided with an external thread, the cap body 1 is covered on the connecting boss 42, and the connecting rod 2 is screwed into the mounting hole 421. Since the implant assembly 2000 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0045] The abutment protection cap 1000 is usually used during the healing period after the implant 3 surgery to ensure that the oral environment around the implant 3 is clean and healthy. The abutment protection cap 1000 covers the abutment 4 to prevent bacteria and food debris from entering the inside of the abutment 4. The abutment protection cap 1000 can also protect the newly implanted abutment 4 from external stimulation and pressure, helping to promote the healing and stabilization of the implant 3.

[0046] Further, in one embodiment of the present invention, please refer to Figure 5 The connecting boss 42 is in a truncated cone shape, and the cross-sectional area of ​​the connecting boss 42 gradually decreases from one end of the connecting boss 42 close to the base body 41 to the other end of the connecting boss 42 away from the base body 41. Such a setting can help ensure a firm connection between the artificial crown and the base 4, and also help provide better stability and sealing, thereby ensuring the normal function of the artificial crown during chewing and speaking.

[0047] In order to seal and protect the connecting boss 42, in one embodiment of the present invention, please refer to Figure 1 , Figure 4 and Figure 5The side of the cap body 1 facing away from the bottom wall of the accommodating cavity forms a base matching plane 13 around the accommodating cavity, and the side of the base body 41 facing away from the implant 3 forms a limited position plane 411 around the connecting boss 42. In the use state, the base matching plane 13 abuts against the limited position plane 411, and the connecting rod 2 is located in the mounting hole 421, so that the connecting boss 42 is located in the accommodating cavity as a whole, realizing the closed protection of the connecting boss 42, and preventing bacteria and food residues from entering the interior of the base 4.

[0048] In order to facilitate the installation of the artificial crown, in one embodiment of the present invention, please refer to Figure 5 The side wall of one end of the connecting boss 42 close to the base body 41 forms a plurality of positioning bevels 422, and the plurality of positioning bevels 422 are arranged at intervals around the connecting boss 42. By setting a plurality of positioning bevels 422, it can be ensured that the artificial crown can be connected to the base 4 at the correct angle and position, which helps to ensure the stability of the implant 3 and the functionality and aesthetics of the crown.

[0049] Further, in one embodiment of the present invention, please refer to Figure 4 The bottom wall of the conical mounting groove is formed with a thread groove; a screw rod 43 is provided at one end of the base body 41 away from the connecting boss 42, and the screw rod 43 is screwed into the thread groove.
