Description

Digital Dental Implant Surgery Guidance Device

technical field

The invention relates to a digital dental implant operation guiding device.

Background technique

Modern dental implantology is a new discipline developed gradually based on the theory of osseointegration proposed by Professor Branemark in the 1960s. Dental implants do not really plant natural teeth, but design pure titanium metal with high compatibility with human bone into a cylinder similar to the root of the tooth, and implant it into the alveolar bone in the edentulous area to produce osseointegration with bone tissue. A crown is then made over the implant. It can withstand normal chewing force, and its function and appearance are almost the same as natural teeth. It is known as the third set of human teeth and is the preferred restoration method for missing teeth.

In dental implant surgery, the implantation position, direction and depth of the dental implant are the key factors affecting the success of the surgery. Incorrect positioning and direction deviation may lead to bone cracks in the implant area, perforation of the side wall of the alveolar bone, and root nerve damage, which will bring great difficulties to the subsequent repair of the upper structure. This requires the doctor to be able to accurately grasp the position and direction of the implant. For this reason, many doctors use a positioning guide template to guide the dental implant surgery. Through the correct positioning and precise guidance of the implant surgery guide template, the failure of the implant repair function caused by the inaccurate position and direction of surgical implantation is avoided. The traditional method of making surgical templates is to manually make transparent self-curing plastic or thermosetting plastic templates on plaster models. The disadvantages are that the accuracy is not enough and the visual effect is poor. The surgical template pressed by an air laminator is low in cost and easy to make, but the positioning and guidance accuracy is not high, and it is difficult to obtain the ideal position and direction. It is mainly used to guide the implantation of a single or two adjacent implants. Or implant locations that require less stringent surgery. With the wide application of CT images, many guide templates are derived based on CT templates. This method uses CT tomography to scan the upper and lower jaws of patients with dentition defects or missing patients who wear radiopaque marker templates. Molding techniques to obtain surgical templates.

In dental implant surgery, the implant hole needs to be drilled multiple times to meet the implant implant requirements. Dental implant drills are in order of use: positioning ball drill, pioneer drill, reaming drill and so on. Traditional dental implant guidance methods are mainly divided into two types: single guide plate single sleeve guided implant and multi guide plate multi sleeve multi-stage guided implant. The sleeves of both are fixed on the circular abutment of the guide plate in the way of interference fit, and cannot fall off or be replaced during the operation. Among them, the single guide plate and single sleeve are only used to guide the first drilling, and the subsequent hole drilling is completed based on the doctor's surgical experience, which greatly reduces the accuracy of implantation. The multi-guide plate multi-sleeve is to guide the drilling by making the same shape of the planting guide template and the sleeves of different inner diameters. During the operation, the drill bit of the corresponding hole is guided by changing the template. This causes a waste of materials, and the positioning template needs to be disassembled and placed many times during the operation, which is easy to generate a large positioning error, thereby affecting the accuracy of implant placement.

The sleeves used in most of the existing implant guide templates cannot achieve multi-level drill guidance because they are fixed on the templates. The NobelGuide implant system uses a double-layer sleeve to solve the problem. The double-layer sleeve is divided into inner and outer layers. The outer layer is solidified on the formwork by interference fit like the general sleeve. The inner sleeve is placed inside the outer sleeve and connected by gap fit. The inner sleeves are a series of guide sleeves with the same outer diameter and different inner diameters. During the operation, only the inner sleeves with different apertures need to be replaced to realize the guidance of multi-stage drill bits. However, since the inner and outer sleeves are only connected through gaps and there is no fixing method, it is easy to cause the inner sleeve to rotate with the drill bit during the operation, and the drill bit will shake due to the gap when the drill moves, which is not conducive to the guarantee of the accuracy of the implant hole. The SurgiGuide template is achieved by making a series of guide tunnel templates with different diameters, which is currently the most common method. When guiding drills with different diameters, corresponding guide tunnel templates need to be selected, which has poor clinical operability and secondary positioning errors. At the same time, the production cost of a series of templates is also relatively high.
