This creation is a kind of denture fixing device,It includes an ontology,A located space is formed in the ontology,And an opening is formed on the what ontology,And the ontology has an edge for surrounding the opening,And plural positioning recess is formed on the what edge,Those positioning recess are connected to the located space and are connected to the lateral surface of the ontology,Wherein,The denture fixing device can be arranged on the upper row's tooth or lower row's tooth of what patient,The rectifier that dentist, odontologist can correct tooth jaw coats viscose and is put into the positioning recess of the denture fixing device,Allow rectifier by the support of denture fixing device and the limit of positioning recess and energy strong fix,So the denture fixing device can limit,Rectifier is supported,Reach auxiliary positioning rectifier,And the glutinous precision for setting position of rectifier can be effectively improved.本創作係一種牙托，其包含一本體，該本體內形成一定位空間，並於該本體上形成一開口，且該本體具有一環繞該開口的邊緣，並於該邊緣上形成複數定位凹口，該些定位凹口連通該定位空間並連接至該本體的外側面，其中，該牙托可套設於患者的上排牙齒或下排牙齒上，牙醫師可將齒顎矯正的矯正器塗上黏膠並放入該牙托的定位凹口，讓矯正器受到牙托的支撐與定位凹口的限位而能穩固定位，所以該牙托可限位、支撐矯正器，達到輔助定位矯正器，並可有效提高矯正器黏設位置的精準度。
