Design Of Intelligent Anterior Traction Appliance For Malocclusion

Class III malocclusion is a kind of oral deformity that is difficult to correct.The anterior maxillary traction appliance is an effective means to correct this kind of deformity,which is of great significance for early intervention and treatment.However,the existing aligners have simple structure design,single function,lack of intelligent accessories,and cannot meet the actual needs of users.Therefore,this study selects the orthosis as the research goal,aiming to improve the degree of intelligence of the orthosis,improve the product structure and function and the adaptability.This study first starts with user needs,obtains user descriptions through user interview and observation methods,and uses KJ method to sort out user descriptions to form user demand standards.Combining function analysis and TRIZ object-model to construct component interaction matrix and function-object field model.According to the type of function-object field model,76 standard solutions were used to form a design plan.At the same time,with reference to the principles of orthodontic biology and mechanics,the process and data of finite element analysis were determined,and the design scheme was tested mechanically.For multiple design schemes,the PUGH decision matrix was??used to screen the optimal design schemes.Through data analysis,the obtained head-related dimensions were classified to form product modules of different sizes,and the orthosis model was processed by additive manufacturing technology to shorten the production cycle and improve product matching.In addition,the addition of intelligent sensor modules such as infrared sensing and thermal sensing,in conjunction with the use of the mobile phone APP,realizes the functions of wearing supervision,data collection,processing feedback,remote online consultation,appointment registration,etc.,improving the intelligence of the product and optimizing errors.Jaw deformity diagnosis and treatment process and services.In this study,the design process and method of the malocclusion anterior traction appliance were designed and studied to verify the design process and method.In meeting the mechanical requirements of the product,the matching degree of the product,the way of wearing the appliance and the product intelligence were improved,which provides a reference for the innovative design of related human-machine products.
