A masticatory orthodontic correction device includes at least one correction unit with a rigid body. The correction unit is worn on a maxillary or mandibular dental arch of a patient during mastication, and the shape of the correction unit is maintained without deformation when accommodating teeth. At least one first recess is formed in the correction unit and has a shape which leaves a first space around a first tooth of the maxillary or mandibular dental arch. The first tooth is a tooth in malposition requiring correction, and the first space allows the first tooth to move therein during mastication. At least one buffering member is formed in the first space for transmitting and buffering force between the first recess and the first tooth. The orthodontic correction function of the device is active under occlusal loads generated during mastication.一種咀嚼式齒列矯正裝置，包括至少一為硬質體的矯正單元。矯正單元於進行咀嚼時裝於病患的上顎牙弓或下顎牙弓，且其形狀於容納牙齒後被保持即不變形。至少一第一凹槽形成於矯正單元中，具有一形狀，其提供圍繞上顎牙弓或下顎牙弓中的一第一牙齒的一第一空間。第一牙齒為在異位而需矯正之牙齒，且第一空間允許第一牙齒在其中移動，當進行咀嚼時。至少一緩衝元件形成於第一空間中，用以傳遞及緩衝第一凹槽與第一牙齒之間的力量。當進行咀嚼時，在咬合載荷的作用下，該裝置得以發揮其齒列矯正功能。
