Preparation method of a restoration device for early loss of space between children's replacement dentition

Abstract

The invention discloses a recovery method for early loss of mixed dentition spaces of children. The method is characterized by mainly comprising the following steps: preparing a space recovery and maintaining device; preparing an oral cavity model; preparing a functional tip; wearing the functional tip; and applying stress. The device mainly comprises a retention ring, a slide chute, a main arch wire, a stress applying spring and a baffle plate, wherein the slide chute is fixedly connected with the outer side surface of the retention ring; a penetrating hole adapting to the outline of the main arch wire is formed in the slide chute; a retention hook is arranged on the side wall of the front end of the slide chute; the main arch wire is provided with a U-shaped curve at the front position of the slide chute; and a mobile rod is arranged at the rear end of the U-shaped curve. The device disclosed by the invention is reasonable in design, simple in structure, convenient to use and relatively good in effect of maintaining and recovering mixed dentition spaces of the children.

Description

technical field [0001] The invention relates to the field of oral medical devices, in particular to a restoration method for the early loss of children's replacement dentition space. Background technique [0002] Deciduous tooth caries is the most common and high-incidence disease among children's oral diseases, especially the deciduous molars have a very high caries rate, and severe caries may be complicated by periapical abscess, alveolar abscess, etc., which must be extracted in the end, which is the cause of deciduous molars. leading cause of premature loss. Premature loss of deciduous molars often easily leads to displacement of adjacent teeth, shortened dental arch length, and asymmetrical dental arch, resulting in misplaced eruption of inherited permanent teeth or embedded impaction, resulting in occlusal deformities such as crowding. Children with premature loss of primary teeth are three times more likely to require subsequent orthodontic treatment than normal chil...

AI Technical Summary

Problems solved by technology

[0003] The above commonly used methods have relatively large clinical defects. The main disadvantages are: (1) It is mainly used to maintain the gap after the premature loss of deciduous molars, or a small amount of gap expansion. When the gap is reduced to more than 1mm, the common gap is maintained The device cannot expand the gap, and the adjacent teeth that move forward cannot return to the original position, which further leads to the occurrence of malocclusion of the matching teeth

(2) Even if the force can be adjusted slightly, the orthodontic force cannot be controlled, and the space maintenance is used in the mixed dentition stage of children, and the force must be light, usually about 60 grams

(3) After the deciduous molars are missing, the adjacent teeth tend to move mesially. Even if the ordinary space maintainer can be fine-tuned with force, the molars will go straight back, unable to complete the distal inclination and then stand upright.

(4) The ordinary fine-tuning space maintainer has the power to directly expand the gap after it is brought into the mouth, and it cannot be taken out and adjusted after it is worn in and bonded. Children, as a special group, have immature minds and are likely to cause discomfort in children. Let the child get used to the retainer first, and then apply force
