The occlusal splint device (01) for the treatment of sleep apnea syndrome according to the present invention includes a maxillary molded splint (02) that can be attached to a maxillary dentition, and a mandibular side that can be attached to a mandibular dentition. A molding splint (12), the upper jaw molding splint (02) can be pressed against the lower jaw molding splint (12), and the upper jaw positioning means (05) and the lower jaw positioning means (22) ), And the upper jaw side and lower jaw side positioning means (05, 22) are in close contact with each other, thereby forming the upper jaw side and the lower jaw side in at least one of the longitudinal direction (X) and the lateral direction (Y). The relative position of the splint (02, 12) can be determined, and at least one of the upper and lower jaw forming splints (02, 12) is provided with at least one attachment means (15), a plurality of different Place the positioning means (22a, 22b, 22c) on the same mounting means (15) by replacement. By enabling attached, the relative positions of the molded splint maxillary side and the lower jaw side (02,12), can be defined in at least two different positions. [Selection] Figure 1本発明の睡眠時無呼吸症候群治療用の咬合スプリント装置(01)は、上顎側の歯列に装着可能な上顎側の成形スプリント(02)と、下顎側の歯列に装着可能な下顎側の成形スプリント(12)とを備え、下顎側の成形スプリント(12)に上顎側の成形スプリント(02)を押し付けることが可能であり、上顎側の位置決め手段(05)及び下顎側の位置決め手段(22)をそれぞれ少なくとも１つ備え、上顎側及び下顎側の位置決め手段(05, 22)が互いに密接することより、前後方向(X)及び横方向(Y)の少なくとも一方で上顎側及び下顎側の成形スプリント(02,12)の相対位置を定めることが可能であって、上顎側及び下顎側の成形スプリント(02,12)の少なくとも一方は、少なくとも１つの取付手段(15)を備え、複数の異なる位置決め手段(22a,22b,22c)を、交換により同一の取付手段(15)に取り付け可能とすることで、上顎側及び下顎側の成形スプリント(02,12)の相対位置を、少なくとも２つの異なる位置に規定可能である。【選択図】図１
