Description

Lower jaw edentulous jaw planting assembly, tracker, navigation system and implantation tool

Technical Field

The invention relates to the field of medical instruments, in particular to a lower jaw edentulous jaw implanting assembly, a tracker, a navigation system and an implanting tool.

Background

In the conventional dental implant operation, a patient takes a panoramic picture before an operation, a doctor approximately judges whether the tooth loss of the patient can be repaired in an implant mode by observing the panoramic picture, and the diameter and the length of an implant are approximately determined by the bone quantity displayed on the panoramic picture.

However, because the panoramic film cannot accurately provide bone information of a patient, and due to the limitation of clinical experience of a doctor, the doctor is often required to measure on site in the operation process, but the measurement is only limited to measuring the mesial-distal length and the bone width of a jawbone in an edentulous area, the bone height cannot be measured, blind operation of the doctor is prone to error, nerve damage or the fact that an implant is adjacent to a tooth root is caused, and the traditional dental implant operation is high in risk.

At present, an implant guide plate (hereinafter referred to as a guide plate) is commonly adopted in the non-dental-jaw implant operation to assist in positioning so as to achieve the effect of accurate implant, the guide plate determines the angle, the position and the depth of the implant, and a doctor can accurately implant teeth at the required position of a dental jaw bone according to the guidance of the guide plate.

The planting mode using the guide plate has the following defects:

(1) the guide plate needs to be processed and manufactured by an external feeding skill, the period is long, and the operation period is prolonged;

(2) a gypsum model is required to be manufactured in the planting process, and the expansion rate of the gypsum model and the manufacturing and positioning errors of the guide plate can influence the positioning precision;

(3) the positioning support of the guide plate has two modes of tooth support and mucous membrane support, and for the edentulous case with all missing teeth in the jaw, the positioning guide plate can not be supported by the teeth, and the mucous membrane is generally selected to support the positioning guide plate, but because of the soft property of the mucous membrane and no obvious positioning characteristic on the surface of the mucous membrane, the mucous membrane positioning has certain drift, when the guide plate is placed on the mucous membrane, the mucous membrane soft tissue can deform and has certain flexibility, so that the guide plate is easy to deviate, sink or tilt after being placed in the oral cavity, thereby influencing the positioning accuracy, and when the jaw arch of a patient is relatively flat, the accurate placement position is difficult to find, the precision of the guide plate is influenced, certain influence is caused to the operation precision, and even the guide plate is failed to be planted in serious cases;

(4) for the case of multi-tooth loss, if the positioning of the guide plate is deviated, the positions and angles of all the implants are deviated;

(5) once the guide plate is manufactured, the direction of the implant drill cannot be adjusted in time when the operation is performed according to the guide plate, if the fixed point is inaccurate in the operation, the correction cannot be performed, the implant nest preparation can only be performed according to preoperative design, the controllability is low, and as a mode that the flap is not turned is used, the risk of damaging important anatomical structures exists.

(6) During operation, the guide plate is required to be covered above the planting area, and then the planting pit preparation is carried out, so that the planting area cannot be visualized;

(7) a metal guide pipe used for guiding an implant drill to drill during an operation is usually placed on a circular base of the guide plate, the position and the angle of the guide pipe record the position, the angle and the depth information of an implant pit designed before the operation, and the guide plate is not suitable for a narrow implant area between two teeth due to the existence of the guide pipe;

(8) the guide plate has a certain thickness, so that a lengthened planting drill which is not originally used in a factory is required to be used, and the requirement on the opening degree, particularly the opening degree of the planted tooth, is high;

(9) the guide plate covers the planting area, and the planting drill needs to enter from the vertical direction of the guide pipe of the guide plate, however, due to the limitation of the opening degree of a patient (particularly a tooth grinding area), in the actual operation, the planting drill cannot enter the guide pipe in the vertical direction, so that the guide plate cannot be normally used in the operation, particularly when the opening degree of the rear tooth area is not enough, the guide plate can only be abandoned, the planting drill is directly used for drilling the jaw bone, and the accuracy and the safety of the planting cannot be ensured;

(10) due to the fact that the guide plate is used, most of cooling water flowing out of the mobile phone positioner is blocked by the guide plate outside a preset implant nest area and cannot flow into the implant nest area to be effectively cooled, if the implant nest area is overheated in the operation process, bone cells at the position can be irreversibly necrotic, and accordingly implant operation failure is caused.
