Problems solved by technology

This method of implantation does not require preparation of a hole in the patient's alveolar bone, so it is only suitable for immediate implantation, and only for patients with good bone condition and no or only slight bone defect or bone resorption
In addition, the cost of this personalized implant is high, and it is not suitable for commercialization and large-scale promotion.

Embodiment 1

[0038] refer to Figure 1-7

[0039] A multi-root implant imitating a natural tooth root, including an implant root 1 implanted in the gum and an abutment 3 connected to a crown 2, the implant root 1 includes a root neck 11 and sub-roots 12, and the number of sub-roots 12 is 2- There are three sub-roots 12 tapered from the root neck 11 to the root tip, and the outline of each sub-root 12 is a smooth curve; the root neck 11 completely covers all the sub-roots 12 in the direction of the top view. The subroot 12 and the root neck 11 are implanted in the alveolar bone, and the part of the root neck 11 is wrapped by the gums, and partly implanted in the alveolar strand; the cross section of the intersection of the root neck 11 and the alveolar bone is the largest, and the Taper from the root neck 11 to the sub-root 12 to ensure the feasibility of preparing a hole in the alveolar bone. The section of the root neck 11 of the natural tooth implant root can be oval, such as Figure ...

Embodiment 2

[0048] refer to Figure 8-15

[0049] The difference between this embodiment and the first embodiment is that the abutment part 3 and the implant root 1 are two independent entities, and the abutment part 3 and the implant root 1 are fixedly connected by the abutment screw 36 . All the other structures are the same as the first embodiment.

[0050] The specific structure is as follows: the abutment part 3 and the implant root 1 are fixedly connected by the abutment screw 36, and the abutment part 3 includes the head end 331 of the abutment part connected to the crown 2 and the transmucosal part 332 connected to the implant root 1. The mucosal part 332 is an inverted cone, the root neck 11 is provided with a conical surface 111 adapted to the transmucosal part 332 , and the bottom end of the conical surface 111 is provided with a screw hole 112 adapted to the abutment screw 36 . The abutment part 3 and the implant root part 1 are two independent accessories, which are conveni...

Abstract

The invention discloses a multi-tooth-root implant for simulating a natural tooth root. The multi-tooth-root implant comprises an implant root part implanted into gum and a base part connected with the tooth crown, wherein the implant root part comprises a root neck and sub-roots; the sub-roots gradually contract from the root neck to the root tip; the contour line of each sub-root is a smooth curved line; the sub-roots are bent in the shape of a natural tooth root; the sub-roots are arranged in parallel; and the sub-roots are completely covered by the root neck in the overlook direction. The multi-tooth-root implant has the advantages of similarity to the natural tooth root and capability of excellently simulating the characteristics of biting and conductivity of the natural tooth.

Description

technical field [0001] The invention relates to a multi-root implant that imitates natural tooth roots. Background technique [0002] Dental implants are becoming more and more popular among the options for the restoration of missing teeth. Compared with traditional restoration methods, dental implant restoration methods have the advantages of good retention, greatly improved chewing efficiency compared with traditional dentures, beautiful and comfortable, no foreign body sensation, and no damage to adjacent teeth. [0003] The traditional dental implant restoration method includes the following periods: firstly, it needs 3 to 6 months of treatment after tooth extraction, waiting for the bone to heal. Next, a hole is drilled in the original extraction socket with a drill, and a traditional threaded or cylindrical implant is inserted into the pre-drilled hole. Finally, the implants are osseointegrated a few months after placement, and the artificial teeth are secured to the...
