Embodiment

[0051] This embodiment provides a dental implant, including an implant screw 1, an implant abutment 2, a locking screw 3 and a crown, and the implant screw 1, the implant abutment 2, the locking screw 3 and the crown are all made by 3D printing .

[0052] The first thread 11 adopts a fine thread with a thread inclination angle of 4°-6° and a thread depth of 0.10mm, and the first thread 11 is arranged on the upper end of the implant screw 1, so as to realize the rapid combination and growth of the cortical bone; through the first thread 11 can quickly lock the implantation angle and implantation depth of the implantation screw 1, providing the implantation screw 1 with stability at the initial stage of implantation.

[0053] The second thread 12 adopts a thread inclination angle of 6 °-10 ° coarse thread, the tooth width of the coarse thread W0=0.4-0.6P0, h0=0.3-0.5P0, where P0 is the pitch of the coarse thread; preferably, the thread depth is 0.15 -0.25mm coarse thread; the s...

Abstract

The invention discloses a dental implant and an implanting method of teeth. The dental implant comprises an implanting screw, an implanting abutment and a locking screw, wherein the lower end of the implanting screw is connected with an alveolar bone, and the implanting abutment is arranged at the upper end of the implanting screw; the implanting abutment is fixedly connected with the implanting screw by adopting the locking screw; a plurality of central through holes are formed in the implanting screw in a penetrating manner, and are parallel to the axis of the implanting screw; a plurality of gradient micropores are formed in the surface of the implanting screw and are used for enabling osteoid and osteogen to grown in; and the gradient micropores are distributed in the radial directionof the implanting screw and are formed in a manner of penetrating through the diameter of the implanting screw. According to the dental implant and the implanting method of the teeth disclosed by theinvention, the central through holes and the gradient micropores are formed in the implanting screw, so that elastic modulus of the dental implant is reduced, the rising compatibility of the dental implant is improved, the failure of implantation caused by osteopenia is avoided; and moreover, the implanting method is simple in operation, is short in healing periods and has a better implanting effect.

Description

technical field [0001] The invention belongs to the technical field of dental implants, in particular to a dental implant and an implantation method thereof. Background technique [0002] Modern dental implant technology has developed into an independent research category in mature stomatology supported by multi-disciplinary cutting-edge technologies, and has established a more scientific, more reasonable and more complete new concept and method. Compared with traditional dentures, the load of implants is transferred to the surrounding biological tissues, which has significant advantages, so dental implants have developed rapidly in recent years. [0003] At present, the chewing function of dental implants is superior to that of traditional dentures. Its advantages such as good implant stability, aesthetics and comfort, and one-time implantation have become the first choice for patients with missing teeth or tooth plastic surgery. Many existing oral implants are generally t...
