Method for manufacturing dental prostheses, comprising the following operations: defining a layered numerical representation of a dental prosthesis (11) for a first layer of the numerical representation, prepare a corresponding layer of a light sensitive liquid substance (6) selectively solidify the layer of liquid substance (6) to obtain a first sheet (7) having a geometry corresponding to the geometry of the first layer of the numerical representation repeat the operations of preparing a layer of liquid substance (6) and selectively solidify the layer of liquid substance (6) for each subsequent layer of the numerical representation to obtain corresponding sheets (7) cause the mutual adhesion between said sheets (7) modify the composition of the liquid substance (6) after having solidified one of the sheets (7) and before solidifying the subsequent sheet (7), so as to modify one or more optical properties of the liquid substance (6).提供一種假牙製作方法,包括下列操作步驟:定義假牙(11)的層狀物數字表示;對於層狀物數字表示的第一層狀物,製備光敏感液態物質(6)的相關層狀物;選擇性地固化光敏感液態物質(6)的相關層狀物,以獲得第一片狀物(7),第一片狀物具有幾何形狀,幾何形狀是相關於層狀物數字表示的第一層狀物的幾何形狀;重複製備光敏感液態物質(6)的層狀物的操作步驟,並對於層狀物數字表示的每一接續層,選擇性地固化製備光敏感液態物質(6)的層狀物,以獲得相關片狀物(7);使片狀物(7)間相互附著;以及,在已經固化片狀物(7)之一後,且在固化接續片狀物(7)前,修飾光敏感液態物質(6)的組成,以修飾光敏感液態物質(6)的一或多個光學性質。
