Dental instrument and orthodontic system for adjusting the relationship between the upper and lower jaws

technical field

The utility model relates to the technical field of medical appliances, in particular to a dental appliance and a dental orthodontic system for adjusting the relationship between upper and lower jaw positions.

Background technique

Malocclusion refers to the phenomenon of dental and jaw deformity caused by congenital genetic factors or acquired environmental factors in the process of children's growth and development. Developmental trauma, periodontal disease and other factors. The formation factors and mechanisms of malocclusion are complex, and its occurrence process may be caused by a single factor and a single mechanism, or it may be the result of a combination of multiple factors or multiple mechanisms.

According to Angel's classification, malocclusion is divided into class I (neutral), class II (distal), and class III (mesial). Among them, class II malocclusion is one of the common malocclusion deformities in orthodontics. The typical manifestations of class II malocclusion are maxillary anterior protrusion, deep coverage of anterior teeth, deep overbite, open lip and exposed teeth, and introversion type. Deep overlap, the lower part of the face is too short or the chin-labial groove is deep. For patients with mild to moderate mandibular retraction, due to insufficient mandibular development, the patient is in the growth and development period, and some patients are even at the peak of growth and development, using functional appliances such as Twin-Block, muscle stimulator, Herbst appliance, functional adjustment Organ type II (FR-II) can stimulate and promote the forward growth of the mandible, and can play a good role in the treatment of deep coverage of the anterior teeth and the relationship between the distal molars of many Class II malocclusions.

The Herbst appliance is a fixed occlusal advancement device for Class II malocclusion. Its mechanical part consists of a pair of metal sleeve systems, which are located on the upper and lower premolars and the buccal side of the molar area respectively. Each sleeve system consists of It consists of a sleeve, a piston rod, two pivots and two screws. The Herbst appliance is welded to the buccal anchorages located on the maxillary first permanent molar and mandibular first premolar through two pivots on each side, and then occlusal through the screw through the sleeve and the shaft hole at the end of the piston rod. The advancement device (ie the sleeve and the insertion rod inserted into the sleeve) is fixed on the shaft seat on the above-mentioned anchoring retainer. After the appliance is in place, the entire sleeve device is similar to forming a pair of artificial joints between the upper and lower jaws, keeping the lower jaw in the forward position, opening and closing the mouth freely, and a little lateral movement. But the downside of the Herbst appliance is that the mandibular range of motion is limited.

In recent years, invisible orthodontic appliances have been chosen by more and more people because of their comfortable, removable and beautiful appearance, but how to combine the functional orthodontic effect of Herbst appliances with invisible appliances to achieve the same or better performance The orthodontic effect, or the structural improvement of the invisible appliance to achieve the same or better orthodontic effect of the Herbst appliance, is the problem to be solved.

Therefore, it is of great significance to study a dental instrument that can adjust the relationship between the upper and lower jaw position taking into account safety, comfort and convenience.

In view of the problems existing in the prior art, referring to FIGS. 1 to 13 , an embodiment of the present invention provides a dental appliance for adjusting the relationship between the upper and lower jaw positions. Specifically, under the action of the dental appliance, the lower jaw is driven to move forward. , to achieve the effect of mandibular protruding, so as to adjust the relationship between the upper and lower jaw to be normal.

The dental appliance includes a first shell-shaped body 10 for accommodating upper teeth and a second shell-shaped body 20 for accommodating lower teeth, the first shell-shaped body 10 and the second shell-shaped body 20 are respectively divided into anterior and posterior teeth. Among them, the "posterior area" is defined according to the classification of teeth in pages 36-38 of the second edition of "Introduction to Stomatology" published by Peking University Medical Press, including premolars and molars, which are displayed as 4- 8 teeth, the anterior region FDI labeling method showed as 1-3 teeth. In addition, the mesial surface and the distal surface are two surfaces adjacent to the crown and the adjacent tooth, and are collectively referred to as the adjacent surface. The side closer to the midline of the face is called the mesial face, and the side farther from the midline of the face is called the distal face.

The anterior teeth area of the first shell-shaped body 10 can be used to accommodate the central incisors, lateral incisors and canines of the maxillary teeth, and the posterior teeth area of the first shell-shaped body 10 can be used to accommodate the first premolars and the second anterior teeth of the maxillary teeth. molars, first molars, second molars and third molars, the anterior region of the second shell-like body 20 can be used to accommodate the central incisors, lateral incisors and canines of the mandibular teeth, and the posterior region of the second shell-like body 20 Can be used to accommodate the first premolars, second premolars, first molars, second molars and third molars of the mandibular teeth.

Referring to FIGS. 1 to 4 , in Embodiment 1, the buccal surface of the first shell-shaped body 10 is protruded from the buccal surface of the posterior tooth region toward the opposite jaw, and is provided with a raised portion 11 for adjusting the relationship between the upper and lower jaw positions, and the raised portion 11 has a relative convex The mesial surface 111 of the raised portion and the distal surface 112 of the raised portion, the second shell-shaped body 20 protrudes from the buccal side to the buccal side and is provided with a limiting portion 21 , and the limiting portion 21 has the opposite limiting portion mesial surface 211 and The distal surface 212 of the limiting portion, when the first shell-shaped body 10 interacts with the second shell-shaped body 20, drives the protruding portion 11 to interact with the limiting portion 21. The mesial surface 111 of the raised portion interacts with the distal surface 212 of the limiting portion of the limiting portion 21 to adjust the relationship between the upper and lower jaw positions.

In one embodiment, the protruding portion 11 is formed by extending along the buccal side of the first shell-shaped body for accommodating the maxillary teeth toward the opposite jaw. The lingual side of the protruding portion 11 is formed. It can extend toward the opposite jaw along the position of the buccal tip of the teeth in the posterior tooth region of the first shell-shaped body 10 . The protruding portion 11 includes an action end, and the action end at least partially covers the buccal side of the second shell body 20 when the first shell body 10 and the second shell body 20 are stably acting. The raised portion 11 formed in this embodiment can not only interact with the limiting portion 21 to adjust the relationship between the upper and lower jaw positions, but also make the patient feel less foreign body on the cheek side and be more comfortable to wear.

In another embodiment, the protruding portion 11 is formed by extending along the buccal side of the first shell-shaped body 10 for accommodating the maxillary teeth toward the opposite jaw. The buccal side of the protruding portion 11 may be Protruding from the buccal side of the first shell-shaped body 10 for accommodating the maxillary teeth, the lingual side of the protrusion 11 can extend toward the opposite jaw along the position of the buccal cusps of the posterior teeth of the first shell-shaped body 10 . The protruding portion 11 includes an action end, and the action end at least partially covers the buccal side of the second shell body 20 when the first shell body 10 and the second shell body 20 are stably acting.
