Description

Technical Field

[0001] The utility model relates to the technical field of tooth correction, in particular to a tooth space maintainer. Background Art

[0002] When children lose their teeth early, a gap will be formed on the gums. The adjacent teeth in the gap tend to tilt toward the gap as they grow, and the adjacent teeth tend to stretch into the gap, thus occupying the growth space of the new teeth. As a result, the new teeth tend to stretch outside the gap, causing the new teeth to be crooked as a whole, and appearing crooked in shape compared to other teeth on the gums, affecting the overall beauty of the teeth. Therefore, space maintainers are needed to maintain the position gap of the missing teeth.

[0003] As shown in the application document with the prior art publication number CN215019350U, it includes a collar, the outer wall of the collar is symmetrically threaded and rotatably connected with a screw, one end of the screw is rotatably connected with an arc-shaped clamping block, the arc-shaped clamping block and the collar are movably connected, the outer wall of the arc-shaped clamping block is fixedly connected with a first telescopic rod, the first telescopic rod and the collar are fixedly connected, the outer wall of the collar is fixedly installed with a hollow sleeve plate, the two sides of the hollow sleeve plate are symmetrically and movably connected with elastic locking blocks, the interior of the hollow sleeve plate is fixedly installed with a second telescopic rod, and the surface of the second telescopic rod is sleeved with a telescopic spring. This technical solution sleeves the collar on the surface of the abutment tooth, and through the knob handle, the handle drives the screw thread to rotate, and the screw pushes the arc-shaped clamping block and the first soft pad to move horizontally. When the inner wall of the first soft pad is in close contact with the outer wall of the abutment tooth, the knob handle is stopped, thereby completing the fixation of the collar and the abutment tooth.

[0004] However, the above technical solution requires rotating the two handles in turn to drive the corresponding arc-shaped clamping blocks to move inward and contact the teeth, and also requires the use of elastic locking blocks and telescopic springs to fix the adjusted connecting plates. The steps are numerous and cumbersome, and it also requires a long time to operate inside the mouth, which will affect comfort and easily cause oral contamination. Utility Model Content
