The invention relates to a method for the production of a dental article, the method comprising: - performing a three-dimensional scan of a portion of a dental arch including at least part of a tooth； - generating a first file containing a three-dimensional model of the at least part of tooth scanned, said three-dimensional model comprising (i) spatial coordinates, in a three-dimensional space having an elevation axis Z, of a plurality of points belonging to an outer surface of the at least part of the tooth scanned and (ii) a colour of the outer surface associated with each point of the plurality； - processing the first file by associating a same colour with all the points having the same coordinate value in the elevation axis Z, thereby obtaining a second file； - sending the second file to a laser stereolithography machine； - obtaining a stereolithographic model of said at least part of tooth based on said second file by subsequent polymerization of layers of a liquid material arranged along the elevation axis Z, so as to obtain the stereolithographic model having for each coordinate value in the elevation axis Z a same colour as present in said second file.本案有關用於製造一牙科物品的方法，該方法包含下列步驟： - 對一牙弓之一部分進行三維掃描，該牙弓之該部分包括一顆牙齒之至少局部； - 產生一第一檔案，該第一檔案內含經掃描之該顆牙齒之該至少局部的一三維模型，該三維模型包含(1)複數個點在具有一高度軸Z的一三維空間中的空間座標，該複數個點屬於經掃描之該顆牙齒之該至少局部的一外表面，及(2)與該複數個點之各點相關聯的該外表面的一顏色； - 藉由將在該高度軸Z中具有相同座標值的全部點與一相同顏色相關聯來處理該第一檔案，藉以獲得一第二檔案； - 傳送該第二檔案至一雷射立體光刻機； - 藉由後續的沿著該高度軸Z排列之層的聚合化，獲得該顆牙齒之該至少局部的基於該第二檔案的一立體光刻模型，該等層具有一液體材料，所獲得的該立體光刻模型中對於該高度軸Z中的各座標值有與該第二檔案中呈現的相同顏色。
