Problems solved by technology

[0003] However, during clinical implant surgery, due to the limitation of line of sight and the lack of reference objects, it is difficult for doctors to accurately judge and check the axial direction of the implant during the operation. It mainly relies on visual inspection for calibration. Afterwards, the CBCT image is used to check; however, visual inspection is highly dependent on the experience of clinicians, and the error is relatively large, and the postoperative image check is lagging, so it often causes bad three-dimensional positions such as implant tilt, which is difficult to make up for. Leaving hidden dangers for later repair and long-term prognosis
The current method to solve this problem is planting real-time navigation technology, but this method is still in its infancy, the accuracy needs further research, and the cost of patient treatment will increase, so it will not be popularized in the short term

Embodiment 1

[0057] This embodiment provides a device for measuring the axial angle of a dental implant, including a rod a1, a rod b2, a rod c3, a rod d4 and a joint 5, such as figure 1 and figure 2 Shown:

[0058] The rod a1 includes a-head rod 11 and a-tail rod 12 connected to each other, one axial end of the a-head rod 11 is fixedly connected with the axial end of the a-tail rod 12, and the a-head rod 11 The axis line coincides with the a-tail bar 12; the bar b2 includes the b-head bar 21 and the b-tail bar 22 connected to each other, and the axial end of the b-head bar 21 is connected to the b-tail bar One axial end of 22 is fixedly connected, and the centerlines of b-head rod 21 and b-tail rod 22 coincide; the rod c3 includes c-head rod 31 and c-tail rod 32 connected to each other, c- One axial end of the head rod 31 is fixedly connected to the axial end of the c-tail rod 32, and the axis lines of the c-head rod 31 and the c-tail rod 32 coincide; the rod d4 includes interconnected ...

Embodiment 2

[0073] The device provided in Example 1 is used for the analysis and measurement of the axial angle of the implant in dental implant surgery, and the specific operation method is as follows:

[0074] (1) Check the axial angle of the cavity during implant surgery:

[0075] 1. Axial inspection method in the anterior region

[0076] 1.1. When designing the implant axis through CT images before implant surgery, after adjusting the relationship with the opposing teeth and adjacent teeth, confirm the implant axis, and measure the expected axis of the implant and the labial bone wall or palatal bone wall. the included angle;

[0077] 1.2. After the positioning drill is fixed in the implant surgery, rotate the rod c and the rod d with the joint as the center, and adjust the opening angle between the rod c and the rod d to the expected angle of design; then, in the flap case: put the c-head The c-head rod or d-head rod is placed along the labial or palatal bone wall; in non-flap case...

Abstract

The invention discloses a device for measuring an axial angle of an implant in a dental implant operation. A first rod comprises a firsthead rod and first tail rod which are connected with each other,a second rod comprises a second head rod and second tail rod which are connected with each other, a third rod comprises a thirdhead rod third tail rod which are connected with each other, and a fourth rod comprises a fourth head rod and fourthtail rod which are connected with each other, the first tail rod of the first rod is connected with third tail rod of the third rod,the first rod is at an angle alpha with the third rod, the second tail rod of the second rod is connected with the fourth tail rod of the fourth rod, the second rod is at an angle alpha with the fourth rod, the third rod ishinged with the fourth rod through a joint, the joint is slidably arranged along the tail end of third tail rod and the fourth tail rod, the first rod (second rod) is linked with the third rod (fourthrod), the axial lengths of the first rod and second rod are both smaller than the axial lengths of the third rod and fourth rod. The analysis and measurement device can be used for checking the axialangle of a cavity when an implant operation is carried out, measuring the angle of a mouth when implanting and repairing are carried out and measuring the angle of a model when the implanting and repairing are carried out. The operation is simple, fast, and low in cost and the measurement results are accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of oral cavity or dental hygiene, in particular to a device for measuring the axial angle of an implant in dental implant surgery and an analysis and measurement method. Background technique [0002] Dental implants have gradually become the preferred restoration method for patients with missing teeth because they can obtain similar functions, structures and aesthetic effects to natural teeth. Implantation technology is widely used in clinical treatment, a large number of implantation cases have emerged, and a large number of problems have also emerged. At this time, people began to pay attention to the risk control and treatment of implants, and the principle of implant treatment was changed from the original "surgery-oriented implant denture restoration" to "restoration-oriented implant denture restoration". Dental implants include implants in the bone and the upper prosthetic structure. The three-dimensi...
