The utility model relates to the technical field of
medical instruments, in particular to a 3D printing integrated gap
retainer which comprises a
workbench used for supporting the whole device, a manufacturing mechanism used for conducting integrated printing forming on the instruments is arranged on the
workbench, and an adjusting mechanism used for adjusting and adapting the instruments is arranged on one side of the manufacturing mechanism. According to the utility model, the manufacturing mechanism is arranged, so that the device can be used for integrally manufacturing the gap
retainer, and intraoral data of a child patient is obtained through the oral
scanner, so that an oral tooth model of the child patient is preferentially printed through the 3D printer, and then the gap
retainer is integrally and accurately manufactured through
computer aided design and a 3D printing technology; the gap retainer is applied to gap maintenance of a child patient suffering from early
deciduous teeth loss, the problems that manual manufacturing is poor in precision and not high in tooth
adaptation degree are solved, the manufacturing process of the gap retainer is time-saving and labor-saving, and the precision and the
adaptation degree are also greatly improved.
