An implant system for an artificial tooth, which is widely used at present, includes an implant implanted into a gingival bone, an abutment combined to an upper portion of the implant, and an abutment fixing screw fastening the abutment to the implant. The above-described fixing member generally widely employs a member made of a titanium alloy in view of mechanical strength, corrosion resistance and machinability. As a material of the fixing member, titanium has advantages of light weight, large rigidity, strong corrosion resistance, excellent biocompatibility, and the like.

Fig. 1 shows a schematic structural view of a conventional dental implant system, in general, during a dental implant operation, an implant 10 made of titanium alloy and having external threads 11 is screwed into a gingival bone to be fixed, the implant 10 and the gingival bone are firmly combined through healing for 4-8 weeks, then an abutment 20 is mounted on the implant 10, an abutment fixing screw 30 is screwed into a central screw hole 12 of the implant 10 to fix the abutment 20 and the implant 10, and finally a crown (not shown) is mounted on the abutment 20 by means of bonding or screw connection. After the artificial tooth is implanted, the implant 10, the abutment fixing screw 30, the abutment 20 and other connecting parts are inevitably loosened by the long-term occlusion, and the abutment fixing screw 30 is loosened after the long-term use, which may occur, and the fastening needs to be periodically checked.

In response to the above-mentioned drawbacks of prior art implant systems, various improved technical solutions have emerged. For example, the dental implant system disclosed in CN 206761780U improves the structure of the abutment fixing screw, and two threaded portions are provided on the screw, so that the screw, the implant and the abutment are all in threaded connection, and the rigidity and stability of the screw connection are improved.

CN 107582192a discloses a dental implant, wherein a spiral coil is provided between a central screw hole of the implant and a screw thread portion of an abutment fixing screw, the abutment fixing screw is coupled to the screw hole of the implant with the spiral coil as a medium, and the spiral coil absorbs and buffers an external force or a repetitive load transmitted through the abutment fixing screw, thereby realizing a firm coupling between the abutment fixing screw and the central screw hole of the implant.

In the dental abutment and the dental implant system having the same disclosed in CN 206880748U, in order to ensure a stable fit between the abutment and the implant for a long time, a regular hexagonal surface for the abutment to fit with the implant is improved, a contact area is increased, a manufacturing form and position tolerance is relaxed, and mass production is facilitated. This prior art demonstrates, need to ensure the position between the two between base station and the planting body and confirm, nevertheless because the threaded connection mode that adopts base station set screw, at the in-process of screwing up base station set screw, must drive the relative planting body of base station and take place the displacement for the position between the two can't be ensured fixedly.

Above-mentioned prior art's implant system all need utilize the base station set screw that has the screw to connect between implant and the base station, because implant installation back, need pass through the repeated installation process of interim base station, permanent base station, dental crown, it all can have the dislocation and the problem of screwing up the degree difference to screw up the base station set screw at every turn, leads to the installation to have the interference of a lot of human factors, and the defect that the mounted position is uncertain and become flexible always exists, therefore the probability of planting failure is higher. In addition, when the abutment fixing screw is screwed in and out of the implant, friction force is always formed on the surface of the thread, on one hand, the implant can be slightly loosened, on the other hand, certain vibration can be formed on the surface of the thread, the vibration can be transmitted to gingival bone and peripheral tissues, a patient who is sensitive to some extent can generate intolerable pain when the screw is screwed, and due to the requirement of firm connection, the stroke of the screw is long, and the patient is greatly injured by long-time screw screwing.

The marble 24 can be made of nylon or other materials, when the base 20 is inserted into the implant center hole 13, the marble 24 can roll along the inner side wall of the implant center hole 13 conveniently, the snap can be realized by only needing small transverse force to roll the marble 24 and overcoming the elastic action of the spring 26, and once the marble 24 rolls to the position of the pit 14 to fall into the pit 14, the point contact of the marble 24 and the inner side wall can be changed into the line contact with the edge of the pit 14, the contact area is enlarged, thereby increasing the friction force, the marble 24 can be separated from the pit 14 by large transverse force during the disassembly operation, thereby further increasing the difficulty of the base 20 in separating from the implant center hole 13, improving the firmness and safety of the snap structure, and avoiding the base 20 from being separated from the implant center hole 13 accidentally. That is, the ball 24 and the corresponding recess 14 of this embodiment can provide automatic positioning and locking functions.

That is, in the embodiment shown in fig. 2, the dental implant system of the present invention completely omits the abutment fixing screws for connecting the implant and the abutment in the prior art, but the abutment 20 can be conveniently clamped on the implant 10 through the snap structure by providing the snap structure, which saves the fixing screws and the cost on one hand, and on the other hand, the present invention can be assembled and disassembled without tools, the connection is convenient and fast, the snap position is accurately positioned, the operation is repeatable, and the pain of the patient is greatly reduced.

In addition, since the occlusion of the tooth usually only applies force to the bottom of the implant 10, as long as the abutment 20 is inserted into the implant 10 to a sufficient depth, the abutment 20 will not be separated from the implant 10, and the snap-fit balls 24 can be inserted and pulled in a rolling manner, which facilitates the removal of the abutment 20 from the implant 10 when the crown has a problem. In addition, the tightness degree of the buckle can be adjusted by arranging the springs 26 with different elasticity, the patient feels that the looseness can be replaced by the springs 26 with larger elasticity, and the buckle structure also provides convenience for replacement.

That is, as shown in an enlarged view in fig. 3, the ball hole 25 is provided as a blind hole, and the bottom of the ball hole 25 does not penetrate through the side wall of the base 20, so that the moisture in the base 20 can be prevented from corroding the spring 26 in the ball hole 25. Of course, in order to avoid water accumulation in the base 20, as shown in fig. 2, screw plugs 22 may be provided at both ends of the base center hole 21 of the base 20 to close both ends of the base center hole 21 for reducing the weight of the base 20.

In another embodiment, to effectively retain the ball 24 from escaping from the cover plate central opening 28, it is preferred that the diameter of the cover plate central opening 28 be smaller than the diameter of the ball 24.

In addition, as shown in fig. 2, in order to improve the stability of the snap connection, two rows of pits 14 are arranged on the inner side wall surrounding the central hole 13 of the implant, and the pits 14 in the same row are distributed on the inner side wall of the central hole 13 of the implant at equal intervals; the pits 14 in the same row are equidistant from the top end of the implant 10; the number of the pits 14 in the same row is 3-6.

Further, for convenience of alignment, as shown in fig. 4, 3 to 6 grooves 29 extending along the length direction of the implant central hole 13 are provided on the inner side wall surrounding the implant central hole 13, and the pits 14 are respectively located on the corresponding grooves 29; the ball 24 can move along the groove 29 to a position where it snaps into the recess 14. In operation, the balls 24 on the abutment 20 are inserted into the implant 10 by aligning the balls 24 with the respective grooves 29, so that the balls 24 can be aligned with the respective recesses 14 conveniently and quickly, otherwise, the alignment may need to be performed by rotating the abutment 20 for many times during the insertion, which increases the difficulty of operation. And the operation time can be reduced by arranging the groove 29, the pain feeling of a patient caused by long-time operation is reduced, and the comfort of the operation is improved.
