Description

A kind of wrong jaw abnormality appliance

Technical field

This utility model belongs to the mouth cavity orthodontic technical field, is specifically related to a kind of appliance that is applied to rescue wrong jaw abnormality.

Background technology

Because of growth and development stage and grow early stage upper jaw deficiency of development and cause the wrong jaw abnormality of bone iS-One III class (be commonly called as " Bao Tian ") easily, this kind deformity also is referred to as the anti-jaw of labial teeth, it is common clinically a kind of wrong jaw abnormality, have a strong impact on the growth of growing up normally of child's craniofacial region, and along with the development degree of deformity of time can increase the weight of gradually.Mainly correct by child's interlock appliance clinically now, existing fixed formula interlock appliance comprises bonding base cheek screen and is connected the horizontal palate bar that bonding base cheek shields, last palatine arches and lower lip bow, shield by cheek, the combined effect of last palatine arches and lower lip bow eliminate upper lip to upper jaw bone pressure, simultaneously, the local alveolar bone periosteum of tractive, stimulate alveolar bone labial surface bone apposition, remove buccinator muscle to the inhibitory action of upper jaw side growth, stimulate upper jaw bone laterally to grow, but this kind appliance exist traction effect undesirable, the shortcoming that child's interlock foreign body sensation is strong.

The utility model content

The technical problems to be solved in the utility model is to provide the wrong jaw abnormality appliance that a kind of traction effect is good, child's interlock foreign body sensation is little at above-mentioned defective.

In order to solve the problems of the technologies described above, this utility model provides a kind of wrong jaw abnormality appliance of following structure, it comprises that the two cheek screens that arrange relatively and the upper lip that is connected between the two cheeks screen front upper keep off, its construction features is: be connected with the lower lip bow that is positioned at upper lip retaining below between the front portion of two cheeks screen, also be connected with the occlusal lug that is positioned at upper lip retaining lower rear between the middle front part of two cheeks screen, be connected with palatine arches between the rear portion of two cheeks screen, described cheek screen has the evagination section of propping up and the indent section of tightening up of setting from top to bottom and rounding off.

Described upper lip retaining comprises that arc setting and two ends are connected to the anterior upper lip pin of two cheeks screen and the upper lip catch that is connected on the upper lip pin.

Described occlusal lug comprise be connected the linkage section on the cheek screen and be connected between two linkage sections and with the supporting section of the upper lip retaining corresponding setting in middle part.

The outer surface of the described evagination section of propping up is the arc setting of interior thickness maximum, and the bottom of the indent section of tightening up is provided with one-body molded and outward extending lower gum section with it.

After adopting said structure, the lower jaw part fits with following teeth groove, pass on the buccinator muscle pressure restraining its growth, lip retaining and cheek screen part are not only regulated the functional status of lip and buccinator muscle, it also is developmental tooth, alveolar bone, jawbone has made up one and has been converted into favourable local environment, make it in the normal development to greatest extent of a length and width Senior Three direction, cheek screen by this setting is to the tractive of vestibule ditch place periosteum, can stimulate the growth of corresponding alveolar bone to improve the position relation that goes up mandibular bone simultaneously, promote upper jaw bone to grow, mandibular bone is retreated, and the jaw relation is more coordinated, and is the efficient apparatus of the anti-jaw of correction function labial teeth; And this cheek screen and upper lip keep off isostructural setting, and be more comfortable when making child's interlock, foreign body sensation is little, is conducive to the child and wears and rescue.

To sum up, the utlity model has the beneficial effect that traction effect is good, child's interlock foreign body sensation is little.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is the structural representation of a kind of embodiment of this utility model;

Fig. 2 is the structural representation that Fig. 1 overlooks;

Fig. 3 is the structural representation of analysing and observe along A-A line among Fig. 2.

The specific embodiment

As Fig. 1, Fig. 2 and wrong jaw abnormality appliance shown in Figure 3, it comprises the two cheeks screens 1 that relatively arrange and is connected two cheeks and shields upper lip retaining 2 between 1 front upper, be connected with between the front portion of two cheeks screen 1 and be positioned at the lower lip bow 3 that upper lip keeps off 2 belows, also be connected with between the middle front part of two cheeks screen 1 and be positioned at the occlusal lug 4 that upper lip keeps off 2 lower rear, be connected with palatine arches 5 between the rear portion of two cheeks screen 1, as shown in Figure 3, described cheek screen 1 has the evagination section of propping up 1-1 and the indent section of the tightening up 1-2 of setting from top to bottom and rounding off, the outer surface of the evagination section of propping up 1-1 is the arc setting of interior thickness maximum, the maximum ga(u)ge of the evagination section of propping up 1-1 is at 8-12mm, the bottom of the indent section of tightening up 1-2 is provided with one-body molded and outward extending lower gum section 1-3 with it, the about 2-3.5mm of thickness of the indent section of tightening up 1-2 and lower gum section 1-3, the arc of the evagination section of propping up 1-1 and thickness are provided with to be beneficial to and strut maxillary vestibule ditch, being beneficial to upper jaw bone grows, the setting of lower gum section and the indent section of tightening up makes child's wearing more comfortable, has reduced foreign body sensation greatly.

As depicted in figs. 1 and 2, upper lip retaining 2 comprises that arc setting and two ends are connected to upper lip pin 21 and the upper lip catch 22 that is connected on the upper lip pin 21 that two cheeks shield 1 front portion.
