The present invention relates to a dental orthodontic device comprising a carrier, a receiving portion defined on the carrier, a closing member movably disposed on the carrier and corresponding to the position of the receiving portion, and one end disposed on the receiving portion, the other end The colloidal flexible member that is in contact with the closure member, and the colloidal flexible member is in an integrally formed state； the structural design of the colloidal flexible member is integrated in the production process, so that it can be uniformly distributed through the overall flexible deformation. Providing elasticity to push against the fixed closure, and if there is dirt, stone invading the receiving portion, and in contact with the rubber flexible member, since the rubber flexible member is integrally formed without forming a spacing, it does not affect the rubber flexible member. The flexibility provided is such that the present invention achieves uniformity of elasticity to reduce the defect rate, and avoids the practical progress of being stuck by dirt and the like for use.本新型為有關一種牙科矯正裝置，其包括有承載體、界定於承載體上之收容部、活動設置於承載體上且與收容部位置對應之封閉件、及一端設於收容部上，另端與封閉件抵觸之膠質撓性件，此外膠質撓性件係呈一體成型態樣；生產使用時因膠質撓性件呈一體成型態樣之結構設計，故能透過整體撓性變形來均勻的提供彈性推抵固定封閉件，且若有髒汙、結石入侵收容部，且與膠質撓性件接觸時，則因膠質撓性件一體成型沒有形成間距，故不會影響膠質撓性件所提供之彈性，藉此令本新型達到彈性均勻以降低不良率，且避免被髒污等卡死以利使用之實用進步性。
