Description

3D printed mouse model oral cavity planting treatment device

Technical Field

Background

Dentition defect refers to the phenomenon that partial tooth defect of a patient causes incomplete dentition, and is a relatively common disease of stomatology. Dentition defects can affect the patient's chewing function, pronunciation function, oral system health and aesthetics. At present, dental implantation is a common method for repairing missing teeth. However, related researches on implants are still immature, such as osseointegration of special materials, complications of implants, peri-implantitis and the like, and animal models are good bridges for understanding diseases. Currently, implant implantation models have been constructed in different animals. Compared with a large animal model, the method has the advantages of relatively lower raising and living cost of small animals, simple and convenient operation and is a good carrier for constructing an implant model. However, small animals have the defects of narrow open space and the like, and the mouse dental implant animal model constructed by the existing method is difficult to model and has low success rate.

In addition, periodontal probes are the most common and important periodontal specialty examination instruments, mainly for measuring periodontal pocket depth. Periodontal probes are the necessary instruments in dental examinations and procedures, and are the most important tools for diagnosing periodontal disease and judging its severity. However, the oral cavity opening degree is different between humans and animals, and the corresponding peripheral probe structure is greatly different.

Meanwhile, the existing implant animal model and periodontal probe are made of titanium alloy, and the replacement cost is high. Therefore, there is a need for improvement of existing animal model implant tools based on the height and width of the mouse upper and lower jawbone.
