The invention relates to an invisible plastic teeth brace for orthodontics. Primarily, it comprises a first side wall, a second side wall, and a top wall of dental crown formed at a connection portion between the first and second side walls. An orthodontic groove is defined between the first and second side walls and the top wall of dental crown. Furthermore, a hollow hole is formed between the top wall of dental crown and the first and second side walls, or the thickness of the top wall is less than that of the two side walls. Accordingly, when a patient wears the invisible plastic teeth braces of the present invention to chew and bite the food, by the design that a hollow hole is formed at the connection portion between the top wall of the dental crown and the two side walls or the thickness of the top wall is less than that of the two side walls, it can effectively prevent the dental aches and discomfort caused due to that the teeth are pushed by the connection portion between the top wall of the dental crown and the two sides walls after undergoing occlusal pressure.本發明係有關於一種牙矯正之隱形膠套，係主要包含有相對第一側壁及第二側壁，並於該第一側壁及第二側壁上緣處連設有一牙冠頂壁，並使該第一側壁、第二側壁及牙冠頂壁間共同界定出一齒列矯正槽，且使該牙冠頂壁及其與第一側壁及第二側壁連接處成型有至少一鏤空孔或使該處壁厚小於兩側壁厚，藉此，當患者配戴本發明之隱形膠套進食等而於咀嚼咬合食物時，利用將牙冠頂壁及其與二側壁連接處形成有鏤空孔或使該處壁厚小於兩側壁厚設計，即可有效防止牙冠頂壁及其二側連接處於承受咬合壓力後，對牙齒產生推擠作用力，所造成牙齒痠痛不適情形者。
