Abstract

The invention discloses a universal semi-loop space retainer which comprises a supporting rod, a base, a sliding sleeve and a set screw. One surface of the base is an adhesive surface B, and the other surface of the base is connected with the sliding sleeve. The sliding sleeve is provided with a sleeve hole and a threaded hole, the sleeve hole is a through hole penetrating two ends of the sliding sleeve, one orifice of the threaded hole is formed in the wall of the sleeve hole, and the other orifice of the threaded hole is formed in the outer wall of the sleeve hole. The supporting rod is sequentially divided into a first section, a second section and a third section, wherein the first section of the supporting rod penetrates the sleeve hole, the second section of the supporting rod is bent towards the base, the third section of the supporting rod is bent towards the base, and one side of the third section of the supporting rod is a contact surface A. The set screw is screwed into the sliding sleeve from the threaded hole. The universal semi-loop space retainer is small in size, light in weight and high in reliability, strongly overcomes foreign body sensation, cannot irritate gingival mucous membranes, avoids secondary caries, can adjust and intercept lengths according to space sizes and can be used immediately after being fetched.

Description

technical field [0001] The invention relates to a medical appliance, in particular to an interdental space maintainer implanted in the oral cavity. Background technique [0002] During the deciduous period of children, deciduous teeth are lost prematurely due to various reasons, leaving gaps in the deciduous dentition, and the deciduous teeth on both sides of the gap will tilt to the side of the gap due to the loss of support; the opposing teeth will gradually elongate because there is no normal tooth blocking , This will eventually lead to dentition disorder, which will hinder the eruption of subsequent permanent teeth. [0003] Based on this, the space maintainer is used to maintain the gap between the lost teeth and maintain the stability of the dentition. It can solve the problems caused by the premature loss of deciduous teeth. [0004] Although there are many types of existing space maintainers, they are often cumbersome to manufacture, crude in workmanship, unstable...
