Traction device bonded to impacted teeth

Abstract

The invention provides a traction device bonded to impacted teeth. A ceramic bottom plate can be bonded onto the impacted teeth, a stainless steel plate is arranged on the ceramic bottom plate, a stainless steel ball is sunken in a concave ball groove of the stainless steel plate and can make rotary motion in the concave ball groove, a stainless steel rod is arranged at the top of the stainless steel ball, and an external thread is arranged on the upper half part of the stainless steel rod. A length adjusting unit comprises a stainless steel adjusting rod, the top of the stainless steel adjusting rod is inwards provided with an internal thread, the internal thread of the stainless steel adjusting rod is in matched connection with the external thread of the stainless steel rod, and a stainless steel ring is arranged at the bottom end of the stainless steel adjusting rod and connected with a fixed orthodontic appliance through an elastic chain or an auxiliary arch. The stainless steel adjusting rod can play a role in fixing and adjusting the length of the traction device so as to meet the requirement for traction of the impacted teeth at different depths. The traction device is smallin size, stimulation to surrounding tissue is little, and the comfort of a patient is good. Manufacturing is simple and standardized, and batch production is easy.

Description

technical field [0001] The invention relates to the field, in particular to a traction device bonded to impacted teeth. Background technique [0002] Impacted teeth are a common disease in orthodontics, with an incidence rate of 1%-2% in the population. It often occurs in mandibular third molars, maxillary canines, maxillary central incisors and mandibular second premolars. Impacted teeth will cause damage to the integrity of the dental arch, occlusal disorder, and root absorption of adjacent teeth, which will have adverse effects on the normal function and appearance of the oral and maxillofacial region. The treatment of impacted teeth usually adopts orthodontic fixed orthodontic technology to open up the gap. After the surgical window is exposed, the attachment is bonded on the crown of the impacted tooth. The focus and difficulty of treatment. Impacted teeth are divided into two types: buccal impacted teeth and palatal impacted teeth. The superficial buccal impacted tee...

AI Technical Summary

Problems solved by technology

At present, the traction of impacted teeth mostly adopts the method of directly connecting the bonding attachment of impacted teeth and fixing the appliance with ligature wire or rubber chain, but closed traction is inconvenient to add force, and cannot provide continuous force

There are also individual traction devices for impacted teeth on the market, such as gold chains and traction springs. Although the design is simple and easy to produce, they are mostly aimed at superficial impacted teeth. For deeper impacted teeth that require closed traction, hinges or Pulling the spring directly through the gums will undoubtedly increase the soft tissue resistance, and also increase the patient's discomfort and psychological rejection
