Description

Composite simulation device and method for planting needles

Technical Field

Background

The dental implantation restoration technology is characterized in that an implant is implanted into a jaw bone or a bone adjacent to a jaw face of a patient with a tooth loss to replace a tooth root of the lost tooth, and the problems of chewing, pronunciation and beauty are solved through an abutment-crown bridge restoration body connected with the upper part of the implant; the initial implant surgery stage of the technique generally involves two steps, one being implant nest preparation, accomplished using different sized implant needles; secondly, implanting the implant, namely screwing the implant into the prepared planting pit by using a special instrument; the current leading preoperative design is a virtual implantation plan with 'repair as a guide', the correct implantation position of an implant in a bone can be designed in the three-dimensional direction, a digital implantation guide plate is designed on the basis, an entity is formed by means of numerical control cutting or 3D printing technology, and the preoperative design is guided to transfer into the mouth in a half-way or a whole-way manner by matching with corresponding surgical instruments.

Literature research shows that compared with the traditional 'free hand' guide, the digital implant guide-guided implant implantation has great precision improvement, but still has certain error which is the result of a series of error accumulation and mutual compensation generated from different stages and different platforms in the process from preoperative design to surgery; the predominant effect is inherent deflection of the guide plate, also known as mechanical deflection, and the implant pocket preparation phase is caused by the clearance between the drill pin, guide tube, metal collar and platen, which is present in the current mainstream guide plate modes of drill pin-guide tube, drill pin-metal collar and drill pin-platen-metal collar.

In order to explore the maximum deviation of the drill point position possibly caused by the gap under the guidance of the digital guide plate, the following two devices are adopted in the research: 1. simulating alveolar bone by adopting a transparent container and organic glass, fixing a guide plate above the container, installing metal sleeves with different heights according to specific research purposes, and completing simulation preparation at the maximum inclination angle, wherein for a drill point-press plate-metal sleeve model, a handheld or drill-hold press plate needs to be matched; 2. the maximum inclination angle of the drill point in the metal sleeve or the resin guide pipe is researched after the guide plate is fixed without adopting a device for simulating the alveolar bone; substantial preliminary cavities exist in the type 1 research, and reference points and reference lines for position deviation measurement analysis are directly constructed on the basis of the cavities; no substantial preliminary cavity exists in the type 2 research, and a reference point and a reference line for position deviation measurement analysis are constructed on the basis of the drill point; the measurement of the two types of research is completed on the two-dimensional picture; the study of category 1 has the following disadvantages: (1) the surgical instruments including the planter are needed, organic glass is selected to simulate the alveolar bone, the hardness of the artificial glass is higher than that of the alveolar bone, the abrasion of a drill point can be caused, and the cost of a simulation experiment is increased; (2) in the preparation process, the resistance from the simulated alveolar bone can cause the drill point to deviate from a preset path, so that the preparation under the maximum inclination angle cannot be completely realized, and deviation data obtained based on the measurement is small; (3) the deviation analysis adopts a two-dimensional photo, and the position deviation of the prepared cavity in the three-dimensional direction cannot be accurately reflected; the research selects the grid paper as a measurement reference scale, and the grid paper is pasted on the transparent organic glass container and is influenced by factors such as light refraction, so that the accuracy is low; the 2 nd study has the following disadvantages: (1) the drill point does not take a fixed measure under the maximum inclination angle, so the drill point can move in the photographing process; (2) the deviation analysis adopts a two-dimensional photo, and the deviation in the three-dimensional direction cannot be reflected; (3) the shooting angle and the resolution capability of the camera influence the measurement result; (4) the study used a mesh paper as the measurement reference scale, which degrades accuracy when it is not parallel to the preparatory starting plane.
