A dental operation-guiding structure includes a bite plate, a marking plate, and at least one connection frame connecting the bite plate and the marking plate. The bite plate is occluded by lower and upper teeth of a human body. The marking plate includes a plate body and at least one window penetrating the plate body. The plate body is adjacent to a tissue surface, and the window defines a position to be operated. By occluding the dental operation-guiding structure, practical positions, patterns and ranges for the operation can be easily defined. The method for producing the dental operation-guiding structure overlaps a 3D bone image of a target object onto a 3D teeth-mold image thereof to obtain a reconstructed 3D image including clear contours of bones and soft tissues, bases on the reconstructed 3D image to design the dental operation-guiding structure, and finally produces the dental operation-guiding structure by 3D printing.一種牙科手術導引元件，包括一咬合板、一定位片及連接於該咬合板與該定位片之間的至少一連接架。該咬合板可供該人體的上、下牙齒咬合與定位。該定位片包括有一片體、及貫穿該片體的至少一開窗；其中，該定位片的片體是鄰靠於該人體的一組織表面、且該至少一開窗的位置就是將被進行手術的位置。藉由病人牙齒咬合定位該導引元件來直接定義出需進行手術的具體位置、形狀與範圍，藉以輔助牙科手術進行。該導引元件的製法，是先把欲進行手術區域的一骨骼3D影像結合一牙模3D影像疊合來獲得包含骨骼及軟組織之清晰輪廓的一重組後的3D影像；再依據該重組後的3D影像來設計該導引元件，可精確定義出手術時需動刀的具體位置、形狀與範圍。之後，再以3D列印的方式製造該導引元件。
