    • The invention relates to a dental device (1) for dilating the interdental spaces (7, 8). The inventive dental device (1) comprises two interdental matrices (4, 5) for insertion into the interdental spaces (7, 8), two retaining means (2, 3) for the interdental matrices (4, 5) and a spacer device (6, 6', 60, 61, 60b, 61b, 90, 91) for guiding the retaining means (2, 3) in parallel and for separating next but one adjacent teeth (111, 112). Unlike conventional wedges, the inventive dental device (1) allows a better access to the mesial and distal tooth surfaces in the area of the interdental spaces (7, 8) and prevents gingival injuries and damages to the dental enamel caused by the pressure. The embodiments relate to inderdental matrices (4, 5) with a window (9), embodiments of the retaining means (2, 3) for detachably fixing the interdental matrices (4, 5) and spacer devices with separator screws (6, 6', 60, 61) and guide pins (60b, 61b, 90, 91). The inventive dental device (1) is useful in prophylactic or restorative odontotherapeutical methods.
