Embodiment 1

[0030] Embodiment 1 discloses a positioning device for two-stage oral implant surgery, which includes side wings for abutting against the teeth on both sides and a main rod 3 connected to the side wings. The main rod 3 can move and fix a ring 4, and the The top end of the ring 4 is connected to the side bar 6, the ring 4 can rotate around its own central axis, the ring 4 can be inserted into a screwdriver for tightening the healing abutment, and an angle is formed between the side bar 6 and the screwdriver; The main rod 3 has a scale; the main rod 3 has a curvature, and the curvature of the main rod 3 is close to the curvature of the gum; the main rod 3 is telescopic.

[0031] The ring member 4 can be rotated to ensure that the side rods 6 connected to the ring member 4 are located at positions tangent to the gums at different positions of the gums, thereby improving versatility.

[0032] Further, there are two side wings, and the side wings have a curvature corresponding to t...

Embodiment 2

[0052] The method for implant positioning using the positioning device for the second-stage surgery of oral implant as described in Example 1 comprises the following steps:

[0053] Measure the length and curvature of the implant gum;

[0054] Adjust the main rod 3 so that the length and curvature of the main rod 3 conform to the length and curvature of the implant gum;

[0055] Further, taking a single implant as an example, the steps are as follows:

[0056] 1) The implant is implanted in the first stage, and the cover screw is installed with a screwdriver;

[0057] 2) The flanks are respectively offset against the teeth on both sides of the implant; the positioning device for the second-stage surgery of the oral implant is installed;

[0058] 3) Use a screwdriver to connect the cover screw through the ring 4, and record the distance s between the ring 4 and the adjacent teeth on the main rod 3 0 ;

[0059] 4) Adjust the angle of the side rod 6 according to the angle of ...

Embodiment 3

[0067] The difference between embodiment 3 and embodiment 2 is that in embodiment 3, taking two consecutive implants as an example, the steps are as follows:

[0068] 1) The first implant and the second implant are implanted, and the cover screw is installed with a screwdriver;

[0069] 2) The flanks are respectively offset against the teeth on both sides of the first and second implants; the length of the main rod 3 of the positioning device for the second-stage oral implant surgery is adjusted, and the positioning device for the second-stage oral implant surgery is installed ;

[0070] Regarding the installation of the positioning device for the second-stage surgery of the oral implant, the specific steps are as follows:

[0071] Measure the length and curvature of the implant gum;

[0072] Adjust the main rod 3 so that the length and curvature of the main rod 3 conform to the length and curvature of the implant gum;

[0073] Respectively offset the flanks against the tee...

Abstract

The invention discloses a positioning device for second-stage operation of oral implantation. The device can accurately detect the position of teeth, realize accurate medical treatment and reduce second-stage surgical wound of implantation. The device comprises side wings which abut against teeth at two sides and a main rod which is connected to the side wings, the main rod can movably fix an annular piece, the top end of the annular piece is connected to a side rod, the annular piece can rotate around the self central axis, the annular piece can be inserted into a screwdriver for tightening ahealing base, and an included angle is formed between the side rod and the screwdriver; the main rod is provided with scales; the main rod is provided with a curvature, and the curvature of the mainrod is similar to that of the denture; and the main rod is telescopic.

Description

technical field [0001] The invention belongs to the field of dental instruments, and in particular relates to a positioning device and method for oral implantation second-stage surgery. Background technique [0002] With the development of oral implant technology, dental implants are favored by patients with missing teeth and dentists due to their good functionality, aesthetics and comfort. Dental implants are artificial teeth composed of implants in the bone and the connecting structures and restorations above them. The implant is implanted into the alveolar bone through implant surgery, and uses the osseointegration mechanism to form a good combination with the alveolar bone to support the upper restoration of the implant. [0003] The second-stage implant surgery refers to the operation of replacing the implant with a healed abutment to form a gingival cuff after the osseointegration of the implant is completed. It is usually performed 3-6 months after the first-stage im...
