Description

Pendulum appliance

Technical Field

The utility model relates to the field of medical equipment, concretely relates to ware is rescued to pendulum-type.

Background

Crowding of the teeth is the most common form of malposition, and crowding is seen in 60-70% of patients with malposition and is manifested by crowded, misaligned teeth. The incidence of caries and periodontal disease of crowded teeth is higher than that of normally arranged teeth, and the serious teeth can cause difficulty in closing lips, form open lips and tooth exposure, and affect the appearance and beauty. The main mechanism of the crowding of the dentition is the abnormal amount of the teeth and the relatively large amount of the teeth and the relatively small amount of the bones, so the principle of the correction is to increase the amount of the bones or reduce the amount of the teeth to achieve the coordination of the amount of the teeth and the bone and create the condition of aligning the dentition, namely, a gap must be created for aligning the teeth. In the case of mild and moderate crowdedness of the dentition, the far and middle movement of the upper jaw molars can provide clearance for the alignment of the front teeth, so that the proportion of the patients with tooth extraction correction can be effectively reduced.

In the prior art, the orthodontic anchorage for providing molar distal movement for crowding of teeth usually consists of a band ring adhered to teeth and a strut welded to the band ring. The inventor of the utility model finds out through research that the anchorage has the following defects: firstly, the belt ring is in a closed ring shape, when the belt ring is installed on teeth, the size of the belt ring is usually not matched with the shape of the teeth, so that the installation of the belt ring is difficult, the shape of the belt ring is not easy to extrude to be well matched with the shape of the teeth, the installation process wastes time and labor, the possibility of damaging soft and hard tissues in the oral cavity of a patient exists in the treatment process, and meanwhile, the belt ring cannot be precisely attached to the neck of the teeth, food residues and the like are easy to accumulate, so that tooth caries or gum inflammation is caused; second, because the band of anchorage both sides is whole cover on the tooth, consequently need place branch tooth rubber band in the near-far adjacent clearance of tooth earlier usually, in order to separate the gap of placing the band, its cycle is longer, the patient feels uncomfortable, the gap is enough around the tooth, the preliminary cover of band is around the tooth through the extrusion preparation completion after, need take off each band from the tooth and bend the preparation of steel wire in order to accomplish the anchorage again, consequently, the complicated cycle of preparation process of anchorage is long, simultaneously because the travelling comfort of anchorage wearing is relatively poor, the phenomenon of weld part scratch patient's oral cavity soft or hard tissue appears easily.

SUMMERY OF THE UTILITY MODEL

To current for dentition crowding, molar remove far away in provide the anchorage preparation process of correcting power complicated, the installation is wasted time and energy, the patient wears the travelling comfort relatively poor, and is bulky, appears damaging the technical problem of patient's oral cavity soft and hard tissue easily, the utility model provides a ware is rescued to pendulum-type suitable for treating dentition crowding.
