Description

Technical Field

[0001] This utility model belongs to the field of dental instruments, and in particular relates to a dental implant system. Background Technology

[0002] The common sealing methods for existing implant systems are planar sealing or conical sealing. Their function is to ensure the seal between the implant and the abutment. In terms of structural design, they only have one sealing area. During long-term use in the patient's oral environment, microleakage can occur, which can lead to loosening of the implant system, affecting the patient's normal use of dentures. In severe cases, it can lead to periodontitis and bone resorption. Utility Model Content

[0003] In view of this, the present invention aims to propose a dental implant system to solve the problem that implant systems are prone to microleakage, which leads to implant system loosening, causing periodontitis and bone resorption.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A dental implant system includes an abutment, an implant, and a central screw. The abutment is fixedly connected to the implant via the central screw. The abutment has a first groove, a first protrusion, and a connecting portion on its exterior. The implant has a second protrusion and a second groove on its exterior. The second groove is used to fit with the first protrusion to form a first sealing structure. The second protrusion fits with the first groove to form a second sealing structure. The implant has a central portion that fits with the connecting portion of the abutment to form a third sealing structure.

[0006] Furthermore, the base has a central hole for installing a central screw inside, and a retaining plate is also provided inside the base. The retaining plate is located in the middle of the central hole and is used to limit the central screw. The base has a groove and a protrusion on the outside.

[0007] Furthermore, the implant has an internal mounting part for installing a central screw, and a second protrusion and a second groove on the top.

[0008] Furthermore, the first protrusion is an annular protrusion, and the second groove is an annular groove.

[0009] Furthermore, the cross-section of the first protrusion is V-shaped, the cross-section of the second groove is V-shaped, and the first sealing structure is a V-shaped seal.

[0010] Furthermore, the first groove is an annular groove, and the second protrusion is an annular protrusion.

[0011] Furthermore, the cross-section of the first groove is a U-shaped groove, the cross-section of the second protrusion is also a U-shaped surface, and the second layer of seal is a U-shaped seal.

[0012] Furthermore, the mounting part is provided with an upper part, a middle part and a lower part from top to bottom, with the upper part being a hollow cylindrical structure.

[0013] Furthermore, the outer wall of the connecting part is a frustum structure, and the middle part is a hollow frustum structure, so that the connecting part can completely fit with the middle part to form a conical seal.

[0014] Furthermore, the taper of the middle section is a Morse taper of less than 3°.

[0015] Compared with the prior art, the dental implant system of this invention has the following advantages:

[0016] (1) The dental implant system described in this utility model reduces the risk of periodontitis and bone resorption in patients, while also reducing surgical costs, alleviating patient pain, and improving surgical efficiency.

[0017] (2) The dental implant system described in this utility model adopts a triple-fit sealing structure. The multiple fit sealing avoids micro-leakage during use; it has a larger contact area, making the occlusal force distribution more uniform, avoiding stress concentration, and reducing loosening and implant system failure.

[0018] (3) The dental implant system described in this utility model adopts a Morse taper with an angle of less than 3° for the conical surface fit, which produces a cold welding effect after locking, thereby improving the locking strength of the implant system and reducing loosening.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] A dental implant system, such as Figures 1 to 4 As shown, the implant includes a base 1, an implant body 2, and a central screw 3. The base 1 is fixedly connected to the implant body 2 via the central screw 3. The base 1 has a first groove 11, a first protrusion 12, and a connecting part 15 on its exterior. The implant body 2 has a second protrusion 21 and a second groove 22 on its exterior. The second groove 22 is used to fit with the first protrusion 12 to form a first sealing structure. The second protrusion 21 fits with the first groove 11 to form a second sealing structure. The implant body 2 has a central part 232 that fits with the connecting part 15 of the base 1 to form a third sealing structure.

[0031] The base 1 has a central hole 13 inside for installing the central screw 3. The base 1 also has a retaining plate 14 inside, which is located in the middle of the central hole 13 and is used to limit the central screw 3. The base 1 has a groove 11 and a protrusion 12 on the outside.

[0032] The lower part of the base 1 is provided with a connection part 15 for installation with the implant 2.

[0033] The implant 2 has an installation part 23 for installing the central screw 3 inside, and a second protrusion 21 and a second groove 22 on the top. The second groove 22 is used to fit with the first protrusion 12 to form a first sealing structure; the second protrusion 21 fits with the first groove 11 to form a second sealing structure.

[0034] The structure of protrusion 12 and groove 22 are matched.

[0035] Preferably, in order to ensure the sealing performance of the first sealing structure, the first protrusion 12 is an annular protrusion and the second groove 22 is an annular groove; in one or more embodiments, the cross-section of the first protrusion 12 is V-shaped, the cross-section of the second groove 22 is a V-shaped surface, and the first sealing structure is a V-shaped seal.

[0036] The structure of protrusion 21 is matched with that of groove 11.

[0037] Preferably, to ensure the sealing performance of the second sealing structure, the first groove 11 is an annular groove, and the second protrusion 21 is an annular protrusion. In one or more embodiments, the cross-section of the first groove 11 is a U-shaped groove. The cross-section of the second protrusion 21 is also a U-shaped surface. The second layer of seal is a U-shaped seal.

[0038] The mounting part 23 is divided into an upper part 231, a middle part 232 and a lower part 233. The upper part 231 is a hollow cylindrical structure, and the middle part 232 fits into the connecting part 15 of the base 1 to form a third sealing structure.

[0039] Preferably, the outer wall of the connecting part 15 is a frustum structure, and the middle part 232 is a hollow frustum structure, so that the connecting part 15 can completely fit with the middle part 232 to form a conical seal, effectively ensuring the sealing performance of the third sealing structure.

[0040] The taper of the middle section 232 is a Morse taper of less than 3°, which allows the abutment and implant to achieve a cold welding effect after assembly, improving the locking strength.

[0041] A method for assembling a dental implant system:

[0042] Place the abutment 1 above the implant 2, so that groove 11 contacts protrusion 21 and groove 22 contacts protrusion 12. Then insert the central screw 3 into the mounting part 23 through the central hole 13 of the abutment 1. Continue to move the central screw 3 downward until its head engages with the locking platform 14 of the abutment 1. At this point, groove 22 and protrusion 12 are pressed together to form a first sealing structure, groove 11 and protrusion 21 are pressed together to form a second sealing structure, and the middle part 232 fits into the connecting part 15 of the abutment 1 to form a third sealing structure. The conical fit, U-groove fit, and V-fit greatly improve the sealing performance of the abutment system and significantly reduce the occurrence of micro-leakage. The conical mating area uses a Morse taper with an angle of less than 3°, which allows the abutment and implant to achieve a cold welding effect after assembly, improving the locking strength. During use, the patient's biting force can be evenly distributed in the three mating areas, avoiding stress concentration that could lead to periodontitis and bone resorption. The novel structural design can prevent microleakage in the abutment system during use, improve the locking and retention strength of the implant, prevent loosening, reduce patient pain, and reduce surgical costs.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
