The present invention provides an orthodontic component including a dental brace, a connecting member, and an elastic member. The dental brace has a body, an accommodation space is surrounded by the body, and a notch is formed on one side of the body. A recess and an extension portion extend from one side of the sleeve body, a fixing block protrudes from the outer edge of the extension portion, the connecting member has a fixed portion and a traction portion extends from the fixed portion, Two ends of the elastic member are respectively connected to the fixing block and the traction portion. Therefore, during the correction process, only the teeth to be corrected can be moved to reduce the sequelae of the correction. Through the design of the notch, the teeth to be corrected can be moved in a predictable and long distance without the need to frequently change the braces.本創作提供一種牙齒矯正組件，包含有一牙套、一連接件以及一彈性件，該牙套具有一套體、一容置空間由該套體圍構而成、一凹口由該套體之一側凹入、以及一延伸部由該套體之一側延伸而出，該延伸部的外緣突設有一固定塊，該連接件具有一定著部以及一牽引部由該定著部延伸而出，該彈性件兩端分別連接該固定塊與該牽引部。藉此，在矯正的過程中，能夠只移動待矯牙齒，減少矯正後的後遺症，透過該凹口的設計，使得待矯牙齒進行可預測且較長距離的移動，無須頻繁更換牙套。
