The invention provides a gap between teeth of an auxiliary denture, which comprises a denture structure and two supporting plates connected to the denture structure, wherein the denture structure includes an inner crown arranged on the real tooth, a convex block arranged on the top surface of the inner crown in a spherical shape, a plurality of connecting bars arranged on the outer surface of the inner crown, and a position corresponding to the convex block of the elastic sleeve and the outer crown of the elastic clip. The utility model is provided with an inner crown clamped by a convex block and an elastic clamping buckle on the connecting rod.Secondly, the abutting plate is arranged on the inner side of the real tooth, and its shape is relative to that of the real tooth, so that the abutting plate completely fits the real tooth.Therefore, this creation can improve the supporting force of denture structure, avoid shaking or falling off of denture structure after using for a period of time, and then improve the service life of denture structure.本創作提供一種輔助義齒之牙縫間隔板，包含義齒結構及連接於義齒結構之二抵靠板；其中，義齒結構包括設於真牙上之內冠；呈球狀並設置於內冠頂面之凸塊；設置於該內冠的外表面上之複數個連接桿；以及內設有彈性套與彈力夾之外冠，彈性套對應凸塊的位置設置，並套設於凸塊而夾持住內冠，且彈力夾緊扣於連接桿。其次，抵靠板設置於真牙的內側，其外型相對於所抵靠的真牙的外型，使抵靠板完全貼合於真牙。藉此，本創作可提高義齒結構的支撐力，避免使用過一段時間後造成義齒結構的搖晃或脫落，進而提高義齒結構的使用年限。
