[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a dental implant system, such as Figures 1 to 6 As shown, it includes: an implant 1, a base 2 and a locking piece 3; the top of the implant 1 is provided with a placement opening 101, the bottom end of the base 2 is correspondingly inserted into the placement opening 101 of the implant 1, the base 2 is provided with a center hole 201, and the locking piece 3 is correspondingly inserted into the center hole 201, the bottom surface of the base 2 is provided with a socket 202, the screw 301 at the bottom end of the locking piece 3 passes through the socket 202, and a screw hole 102 is provided at the center of the bottom surface inside the placement opening 101, the screw 301 is spirally inserted into the screw hole 102, the locking piece 3 cooperates with the implant 1 to define the base 2, and the bottom end of the implant 1 is installed on the alveolar bone. The gums are cut open with a scalpel, the cut gums are opened, and the drill bit of the punching device is used to punch a hole in the alveolar bone to form a mounting hole. The bottom end of the implant 1 is screwed onto the alveolar bone, and the opened gums are re-covered on the surface of the alveolar bone by suturing until the gums grow back into one piece. Insert the bottom end of the abutment 2 into the placement opening 101 of the implant 1 until the bottom end of the abutment 2 fits into the inner bottom surface of the placement opening 101. At this time, the bottom end of the socket 202 corresponds to the screw hole 102. Place the locking piece 3 vertically inside the center hole 201 of the abutment 2. The downward-moving locking piece 3 allows the bottom end of the screw 301 to enter the screw hole 102 through the socket 202. Use a cross screwdriver to spirally insert the screw 301 into the screw hole 102. Use the spiral cooperation between the screw 301 and the screw hole 102 to stably install the abutment 2 on the top of the implant 1. At this time, it is convenient to install the tooth model on the outside of the abutment 2 to realize tooth implantation.

[0028] The top of the screw hole 102 is provided with a strip groove 104, and the surface of the screw rod 301 is provided with a threaded portion 302. The rotating threaded portion 302 enters the interior of the screw hole 102 through the strip groove 104. When the screw rod 301 rotates, the screw rod 301 drives the threaded portion 302 to rotate synchronously until the bottom end of the threaded portion 302 corresponds to the top end of the strip groove 104. The rotating threaded portion 302 enters the interior of the screw hole 102 through the strip groove 104. Through the cooperation between the threaded portion 302 and the strip groove 104, the bottom end of the screw rod 301 gradually enters the interior of the screw hole 102 until the bottom surface of the locking member 3 is in contact with the inner bottom surface of the center hole 201, completing the stable installation of the base 2.

[0029] exist Figures 1 to 4 In the figure, the bottom of the implant 1 is configured as a truncated cone, and the diameter of the implant 1 decreases from top to bottom. The outer side of the implant 1 is configured as an inclined arc surface, and the inclined arc surface is provided with a thread strip 103, and the thread strip 103 is provided with a plurality of notches 4. The bottom end of the implant 1 is aligned with the mounting hole of the alveolar bone, and the implant 1 is rotated. The rotating implant 1 gradually enters the interior of the alveolar bone using the thread strip 103 until the top surface of the implant 1 is aligned with the top surface of the alveolar bone. The flapped gingiva is then re-covered on the alveolar bone surface by suturing. When the gingiva re-grows, the alveolar bone also re-grows. The regrown alveolar bone cooperates with the notches 4 to restrict the implant 1, preventing the implant 1 from being rotated out of the alveolar bone using the thread strip 103.

[0030] exist Figures 2 to 6 In the embodiment, the bottom of the base 2 is configured as a truncated cone. The inner sidewall of the placement opening 101 is aligned with the outer circumference of the base 2. The bottom end of the base 2 is aligned with the inner bottom surface of the placement opening 101. Two opposing side bars 5 are fixed to the inner sidewall of the placement opening 101. The outer circumference of the base 2 is provided with side grooves 203 corresponding to the side bars 5. The side grooves 203 snap onto the outer sides of the side bars 5. The inner side of the side bars 5 is inserted with an insertion rod 6. The inner side of the side bars 5 is provided with a locking hole 501. The outer end of the insertion rod 6 is inserted into the locking hole 501. The insertion rod 6 is arranged perpendicular to the inner side of the side bars 5. A circular plate 601 is fixed to the inner end of the insertion rod 6. The outer circumference of the locking member 3 is aligned with the inner sidewall of the center hole 201. The locking member 3 is configured as a cylinder. The bottom of the outer circumference of the locking member 3 is provided with a chamfered surface 303. The locking member 3 cooperates to squeeze the inner portion of the circular plate 601. The insertion rod 6 is correspondingly inserted into the inside of the base 2. When the bottom end of the base 2 is inserted into the inside of the placement port 101, the downward-moving base 2 uses the side groove 203 to correspond to the side strip 5 until the bottom end of the base 2 is in contact with the inner bottom surface of the placement port 101. The side groove 203 of the base 2 is correspondingly snapped onto the surface of the side strip 5. At this time, the insertion rod 6 inserted into the inside of the base 2 corresponds to the snap-in hole 501 of the side strip 5.

[0031] When the locking piece 3 is placed inside the center hole 201, the locking piece 3 moves downward inside the center hole 201 until the chamfered surface 303 of the locking piece 3 contacts the inner surface of the circular plate 601. The locking piece 3 continues to move downward by pressing. The locking piece 3 uses the chamfered surface 303 to push the circular plate 601 close to the side strip 5 until the outer side surface of the circumference of the locking piece 3 fits with the inner side of the circular plate 601, and the outer end of the insertion rod 6 is inserted into the clamping hole 501 of the side strip 5.

[0032] The side strip 5 and the side groove 203 are cooperated to prevent the base 2 from rotating inside the implant 1, and the insertion rod 6 and the card hole 501 are used to limit the bottom end of the base 2 from shaking up and down inside the placement port 101 of the implant 1, thereby improving the integration effect of the base 2 and the implant 1.

[0033] exist Figures 2 to 8 In the figure, the top of the screw 301 is connected to the bottom of the locking member 3 via a chamfered surface 303. The locking member 3, which moves downward within the center hole 201, uses the chamfered surface 303 to press against the inner wall of the circular plate 601. The surface of the insertion rod 6 is sleeved with an elastic member 602, which is configured as a spring. The inner end of the elastic member 602 is connected to the outer surface of the circular plate 601. The inner wall of the center hole 201 of the base 2 is provided with a groove corresponding to the circular plate 601, and the groove corresponds to the locking hole 501. The outer end of the insertion rod 6 is inserted into the locking hole 501 through the groove. When the downward-moving locking member 3 utilizes the chamfered surface 303 to squeeze the inner wall of the circular plate 601, the circular plate 601 gradually enters the groove of the center hole 201 under the action of pressure, and the outward-moving circular plate 601 causes the outer end of the insertion rod 6 to gradually enter the inside of the clamping hole 501. The outward-moving circular plate 601 cooperates with the groove to squeeze the elastic member 602 on the surface of the insertion rod 6 until the outer side surface of the circumference of the downward-moving locking member 3 contacts the inner side of the circular plate 601. The elastic force of the elastic member 602 is used to prevent the insertion rod 6 and the circular plate 601 from shaking inside the placement port 101.

[0034] Working principle of the present invention:

[0035] Reference Figures 1 to 8 As shown, the gums are cut open with a scalpel, the opened gums are flapped open, and a hole is punched in the alveolar bone using a drill bit of a punching device to form a mounting hole. The bottom end of the implant 1 is aligned with the mounting hole of the alveolar bone, and the implant 1 is rotated. The rotating implant 1 gradually enters the alveolar bone using the threaded bar 103 until the top surface of the implant 1 corresponds to the top surface of the alveolar bone. The flapped gums are then re-covered on the surface of the alveolar bone by suturing. When the gums grow again, the alveolar bone also grows again. The grown alveolar bone cooperates with the notch 4 to limit the implant 1, preventing the implant 1 from being rotated out of the alveolar bone using the threaded bar 103.

[0036] The insertion rod 6 is correspondingly inserted into the inside of the base 2. When the bottom end of the base 2 is inserted into the inside of the placement port 101, the downward-moving base 2 uses the side groove 203 to correspond to the side strip 5 until the bottom end of the base 2 is in contact with the inner bottom surface of the placement port 101. The side groove 203 of the base 2 is correspondingly snapped onto the surface of the side strip 5. At this time, the insertion rod 6 inserted into the inside of the base 2 corresponds to the snap-in hole 501 of the side strip 5.

[0037] When the locking piece 3 is placed inside the center hole 201, the locking piece 3 moves downward inside the center hole 201 until the chamfered surface 303 of the locking piece 3 contacts the inner surface of the circular plate 601. The locking piece 3 continues to move downward by pressing. The locking piece 3 uses the chamfered surface 303 to push the circular plate 601 close to the side strip 5 until the outer side surface of the circumference of the locking piece 3 fits with the inner side of the circular plate 601, and the outer end of the insertion rod 6 is inserted into the clamping hole 501 of the side strip 5.

[0038] The side strip 5 and the side groove 203 are cooperated to prevent the base 2 from rotating inside the implant 1, and the insertion rod 6 and the card hole 501 are used to limit the bottom end of the base 2 from shaking up and down inside the placement port 101 of the implant 1, thereby improving the integration effect of the base 2 and the implant 1.

[0039] When the downward-moving locking member 3 utilizes the chamfered surface 303 to squeeze the inner wall of the circular plate 601, the circular plate 601 gradually enters the groove of the center hole 201 under the action of pressure, and the outward-moving circular plate 601 causes the outer end of the insertion rod 6 to gradually enter the inside of the clamping hole 501. The outward-moving circular plate 601 cooperates with the groove to squeeze the elastic member 602 on the surface of the insertion rod 6 until the outer side surface of the circumference of the downward-moving locking member 3 contacts the inner side of the circular plate 601. The elastic force of the elastic member 602 is used to prevent the insertion rod 6 and the circular plate 601 from shaking inside the placement port 101.

[0040] When the locking piece 3 allows the bottom end of the screw 301 to enter the screw hole 102 through the socket 202, the screw 301 is screwed into the screw hole 102 using a cross screwdriver, and the screw 301 is spirally matched with the screw hole 102, so that the base 2 is stably installed on the top of the implant 1. At this time, it is convenient to install the dental model on the outside of the base 2 to realize dental implantation.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
