新型动物口腔诊疗支架的研制及应用

Development and application of new-type animal dental stent

目的 :设计一种新型动物口腔诊疗支架,并将其应用于犬牙髓再生实验。方法 :该装置包括上支撑架、口腔限位架和下支撑架3个部分,并依上至下相连接。上、下支撑架高度和宽度为可调节式,且支撑架可旋转,末端为弧形结构。口腔限位架左右两侧为套筒结构,连接套筒结构的上限位杆与下支撑架中的下限位杆为可伸缩式。结果:该口腔诊疗支架能使实验动物稳定维持长时间的张口状态,并可根据不同种类动物的颌面部结构进行三维调整,方便医护人员对动物进行喉部检查、口腔检查、口腔护理及牙科治疗(如根管治疗、牙体充填)和其他医护行为。结论:该口腔诊疗支架设计合理、结构简单、便于携带,方便拆卸与组装,易于消毒与灭菌,且成本低廉,可以起到保护软组织、开放手术视野、隔离唾液污染的作用,值得在临床动物实验以及动物诊所推广使用。

Objective To develop a new-type animal dental stent for the experiment of canine pulp regeneration. Methods The stent was composed of an upper support frame, an oral limit bracket and a lower support frame, which were aligned from top to bottom. A sleeve joint was made for the connection structure of the bracket, and the height and the width both could be adjusted to adapt to different animals＇ mouths. The rubber dam could be spread into tension and concave form by rotating the upper and lower support frames＇ ends. Results By resizing the animal dental stent based on the structure of animal facies maxillaris, medical staffs could proceed the examination and treatment to animals effectively, including the throat examination, oral examination, oral care, dental treatment（such as root canal therapy and dental filling） and other medical behaviors. Conclusion The experimental result shows the feasibility of utilizing the stent in the process of animal experiment or diagnosis and treatment. Moreover, the stent proves the capacity in protecting the soft tissue, widening the vision of operation field, getting rid of the saliva contamination, which is worthy popularizing in animal experiments and animal medical care.
