Description

Removable anterior maxillary traction intraoral correction device

Technical Field

The utility model belongs to the technical field of the device is rescued to the upper jaw, especially, relate to a can pluck and drag intraoral the device of rescuring before upper jaw.

Background

The "classic" of the third generation of the wrong teeth of Anshi refers to the abnormal shapes, sizes and positions of the upper and lower teeth, dental arch and jaw bones in the near and far directions caused by genetic factors and environmental factors. The main clinical features are the relationship between anterior contra-occlusal and molar mesis, which may be accompanied by posterior contra-occlusal. The main point of the surface type is a concave surface type. If the maxilla develops insufficiently or recedes, it usually appears as a flat face, sharp nasolabial angle and collapse of the upper lip. If the mandible grows excessively or is protrusive, the mandible manifests as protrusion of the chin, length of the mandible, short ascending and descending of the mandible, blunt angle of the mandible and eversion of the lower lip.

The class III cross-occlusion of Andes has different degrees of influence on the beauty, chewing function and psychology of the face, and the harms of the cross-occlusion of Andes comprise:

(1) Hampering the development of the jaw bone: either underdeveloped maxilla or underdeveloped mandible leading to abnormal jaw relationships;

(2) Reduction of chewing function: the upper and lower anterior teeth cannot perform the cutting function;

(3) Cosmetic impact hampers aesthetics: the upper jaw is not good enough in development, 1/3 of the face is sunken, the upper lip is collapsed, and the mandibular protrusion is deformed;

(4) Disorders of the temporomandibular joint are easily caused;

(5) Hazards to oral and general health: occlusal wounds, caries, excessive wear, and dyspepsia.

Children and adolescents in their developmental stages need first to be diagnosed if a class iii alloy of anderson is present. For "ground cover days" where mandibular overgrowth or lordosis predominates, there is currently no good way to intervene in the bone, usually by waiting until growth is complete and then diagnosing. For "ground-wrapped days" with maxillary hypoplasia or retrogradation as the main component, the anterior traction appliance can be used for treatment. At present, a mask type maxillary anterior traction appliance and a modified chin pocket type maxillary anterior traction appliance are mainly used clinically. However, either type of device requires the use of an intraoral anterior maxillary traction device.

In clinical treatment, there are very high requirements for retention of the anterior maxillary distraction intraoral device. Since the anterior traction appliance is traction of the maxilla to stimulate the growth of the bone gap around the maxilla, the initial anterior traction force should typically reach 500g per side, and the force should be maximized to 1000g per side as the retention of the appliance allows. The anterior maxillary traction intraoral device needs to be firmly positioned in the mouth under traction of a large force value to transmit force to the maxillary bone.

The anterior maxillary traction intraoral devices may be classified into removable and non-removable types according to the retention method. Wherein the non-removable intraoral device, while securely retained, cannot be removed for cleaning. While the front traction appliance is typically worn for at least more than half a year, it has a greater impact on the oral health of children and adolescents. The removable intraoral device is capable of being removed and cleaned after meals, thereby providing better oral hygiene for children and teenagers and meeting the concept of oral health maintenance. However, removable intraoral devices have drawbacks, mainly including poor retention, and the tendency to become dislodged, which prevents the patient from completing the treatment.
