An orthodontic space closure device is provided, including a first tooth cap unit, a second tooth cap unit, and a number of elastic members. The first tooth cap unit is configured to be removably worn on the anterior teeth of a dental arch of a patient. At least one first connector is fixed on each buccal side of the first tooth cap unit. The second tooth cap unit is configured to be removably worn on the posterior teeth of the dental arch. A vertical extension part is formed on each buccal side of the second tooth cap unit, and at least one second connector is fixed on each vertical extension part. The elastic members couple the first connectors to the second connectors, thereby exerting elastic traction forces having horizontal and vertical components on the first tooth cap unit to achieve retraction and intrusion of the anterior teeth.一種牙齒矯正空間關閉裝置，包括一第一牙套單元、一第二牙套單元以及多個彈性構件。第一牙套單元配置以可摘的方式配戴在病患的一牙弓的前牙上。至少一第一連接器固定在第一牙套單元的各頰側上。第二牙套單元配置以可摘的方式配戴在牙弓的後牙上。在第二牙套單元的各頰側上形成一垂直延伸部。至少一第二連接器固定在每一垂直延伸部上。彈性構件連接第一連接器與第二連接器，藉此在第一牙套單元上施加具有水平和垂直分量的彈性牽引力，以實現前牙的後退和壓入。
