Embodiment

[0028] Root canal irrigation effect dynamic detection model device such as Figure 1-2 As shown, there are transparent tooth model 1, microscope 2, electronic eyepiece 3, notebook computer 4, universal mechanical testing machine 5, syringe 6, root canal irrigation needle 7, transparent tooth model and syringe fixing device 8 abutment and fixing device 9 The various devices and devices are connected to form a whole through connecting pieces. The transparent tooth model 1 is a real tooth scanned by micro-CT (μ-80) to generate a geometric STL file at the same time, and then submitted to a high-precision 3D printer (objet) to make it with transparent materials. The root canal flushing needle 7 is mounted on the front end of the syringe 6. The syringe 6 is generally a 5ml syringe and inserted into the root canal of the transparent tooth model 1. The distance between the root canal flushing needle 7 and the root tip is 5 mm. (Instron5565) connection. The universal mechanical testi...

Abstract

The invention relates to a model device for dynamic detection of root canal flushing effect and a detection method thereof. The invention is characterized in that the device is successively integrated as a whole by a transparent tooth model (1), a microscope (2), an electro-ocular (3), a notebook computer (4), a universal mechanics tester (5), an injector (6), a root canal flushing needle (7), a transparent tooth and injector fixing device (8) and a base station fixing device (9) through connectors. The detection method comprises the following steps: infusing a tracer with colors in the transparent tooth model (1) after connection of the model device for dynamic detection of root canal flushing effect is finished, while filling flushing liquid in the injector (6), driving the injector (6) by the universal mechanics tester (5) and flushing the tracer in the transparent tooth model (1) through the root canal flushing needle (7), and carrying out micro dynamic shooting with the microscope (2) and the electro-ocular (3) and storing in the notebook computer (4) to facilitate analysis of the root canal flushing dynamic effect and influence factors thereof. The method is to provide a scientific study method and clinical therapy basis for flushing the root canal.

Description

technical field [0001] The invention relates to a dynamic detection model device for root canal flushing effect and a detection method thereof, belonging to the field of dental medical experimental model equipment or stomatology. Background technique [0002] Pulp disease and periapical disease are the most common oral chronic bacterial and infectious diseases. Root canal therapy is the most effective method for treating pulp disease and periapical disease. Root canal treatment is effective through mechanical-chemical preparation. Reduce the microorganisms in the root canal and effectively promote the healing of periapical lesions. Due to the complex shape of the root canal, its anatomy varies from tooth to tooth and is very complex. Studies have shown that the existing preparation techniques cannot prepare the entire root canal system, and about 61% of the area cannot be touched by preparation instruments. There are a large number of microorganisms and dentin debris in the...
