The invisible dental brace is made of a transparent material. The adjusting pliers comprise two openable/closable jaws, a first shaping member mounted to one of the jaws, and a second shaping member mounted to another jaw and corresponding to the shape and position of the first shaping member. The first and second shaping members are arranged to mate with each other in a recessed-raised manner so as to be able to form at least one raised portion on the invisible dental brace. The invisible dental brace can be mounted efficiently and the transparent design thereof helps improve aesthetics. Using the adjusting pliers to form a raised portion on the invisible dental brace allows the raised portion to directly contact a specific tooth, capable of providing an effect of strengthened correction to the specific tooth.一種用於矯正牙齒的定位調整裝置,包含一隱形矯正牙套,及一能對該隱形矯正牙套的形狀進行調整的調整鉗。該隱形矯正牙套是由透明材質製成,該調整鉗包括兩個可互相開閤的夾頭、一設置於其中一夾頭上的第一成型件,及一設置於另一夾頭上且對應該第一成型件之位置與形狀的第二成型件,該第一、二成型件是凹凸配合而能於該隱形矯正牙套上形成至少一個凸出部。該隱形矯正牙套不但安裝速度快,且透明設計可提升美觀度,而透過該調整鉗於該隱形矯正牙套上形成凸出部,可使該凸出部直接接觸於特定牙齒上,能針對特定牙齒提供加強矯正的作用。4‧‧‧調整鉗41‧‧‧夾頭42‧‧‧握柄43‧‧‧第一成型件431‧‧‧接觸面44‧‧‧第二成型件
