As shown in fig. 1 to 15, the orthodontic composite appliance includes an orthodontic brace 100 and an orthodontic wire 200, in this embodiment, the orthodontic brace 100 is made of materials including, but not limited to: thermoplastic Polyurethane (TPU) and/or polyethylene terephthalate (PET-G), and the orthodontic wire 200 uses materials including but not limited to: stainless steel, alloy and fiber reinforced composite arch wire.
The orthodontic braces 100 are provided with outer sleeve wall parts 120, the orthodontic wires 200 are nested in the orthodontic braces 100, and the orthodontic wires 200 are positioned on the inner sides of the outer sleeve wall parts 120, or the orthodontic wires 200 are positioned inside the outer sleeve wall parts 120. The orthodontic braces 100 comprise a brace front section 111 and two brace side sections 112, wherein the two brace side sections 112 are positioned on two opposite sides of the brace front section 111 and extend in a lateral and rear direction relative to the brace front section 111; the outer enclosure wall portion 120 includes joined inner wall portions 121, 122 and a top wall portion 123; the orthodontic wire 200 includes at least an anterior wire segment 211 and a lateral wire segment 212, wherein the anterior wire segment 211 corresponds at least in part to the mouthpiece anterior segment 111, and the lateral wire segment 212 corresponds at least in part to the mouthpiece lateral segment 112.
The orthodontic composite appliance comprises an orthodontic brace 100 and an orthodontic wire 200, and when teeth are orthodontic, on one hand, the orthodontic wire 200 is used for enhancing the retention of the orthodontic brace 100; on the other hand, be equipped with outside orthodontic wire 200 and correct facing 100, play the effect of removing the tooth through correcting facing 100, through correcting facing 100 and orthodontic wire 200 two combinations, strengthened the maintenance ability and the parameter expression of correcting facing 100, widened just abnormal compound and rescued the applicable case of ware, improved just abnormal effect of correcting, reduced again the pleasing to the eye influence of user's tooth.
It can be understood that, because the compound orthodontic appliance of this embodiment sets up including correcting braces 100 and the nesting of orthodontic wire 200, correct braces 100 and can directly overlap in tooth 400 surface, and orthodontic wire 200 can not need to carry out fixed connection through bonding or other modes and tooth 400's surface, adopts this mode, also reduces the compound orthodontic appliance's of just abnormal installation, the work load of dismantling, more convenient washing and change.
Further, the front wire section 211 is located on the inner wall portion 121 of the mouthpiece front section 111, and both ends thereof extend in the rear direction and form the mouthpiece side section 112. The orthodontic wire 200 is partially arranged on the inner wall 121 of the orthodontic braces 100, namely, the orthodontic wire 200 is positioned on the inner side of the teeth 400, so that the orthodontic wire 200 is prevented from being exposed to affect the appearance, and the appearance of the orthodontic composite appliance is further improved. Correcting tooth socket 100 and increasing the retention effect of just abnormal compound appearance ware, setting up in the interior wall 121 who corrects tooth socket 100 and the compound appearance ware that corrects whole rigid reduction that causes just abnormal for reducing just abnormal silk 200, just abnormal silk 200's rear side adopts inside and outside two sections, promptly: the front wire section 211 extends in a posterior direction to form a lateral inner section 213 of the mouthpiece-side section 112, and the lateral inner section 213 extends to the vicinity of the posterior end of the mouthpiece-side section 112 and continues from the outside to the front to form a lateral outer section 214 of the front wire section 211. This structure increases the rigidity of the orthodontic composite appliance, and in order to prevent the orthodontic wire 200 from affecting the beauty of teeth, the lateral inner section 213 bypasses the rear side and extends to form a lateral outer section 214, and the lateral outer section 214 ends at both end positions of the front wire section 211.
In order to adapt to the ergonomic principle of teeth, the front wire section 211 is in smooth arc transition integrally, and the side wire section 212 is in wave form fluctuation, so that the appearance of the orthodontic composite appliance and the teeth is attached as much as possible, and the comfort level and the orthodontic effect of the orthodontic composite appliance are improved.
In this embodiment, the inner wall portions 121 and/or 122 of the outer shell wall portion 120 have laterally expanding outer shape high points 124, and the orthodontic wire 200 is closer to the root direction side of the outer shell wall portion 120 than the outer shape high points 124. Because the rigidity of orthodontic wire 200 is better for correcting facing 100, with orthodontic wire 200 set up in being closer to outer jacket wall portion 120's root direction one side, if need take off this just abnormal compound correction ware, just orthodontic wire 200 need cross the position corresponding with appearance high point 124 on tooth 400, and this structure can avoid just falling from the tooth at will just in the compound correction ware of just abnormal, has improved this just abnormal stealthy facing's retention.
To facilitate the nesting arrangement between the orthodontic wire 200 and the orthodontic braces 100, the thickness of the partial region of the outer shell wall 120 is greater than the thickness of the main body of the outer shell wall 120, so as to form the outer wall protrusion 130, the outer wall protrusion 130 has a receiving groove 131 therein, and the orthodontic wire 200 is located in the receiving groove 131. The inner side of the outer sleeve wall portion 120 is provided with an inner opening 132, the orthodontic wire 200 is provided with an orthodontic main body portion 241 and an orthodontic connecting portion 242, the width of the orthodontic main body portion 241 is larger than the width of the inner opening 132, and the orthodontic connecting portion 242 extends to the inner opening 132.
The structure of the semi-finished product of the orthodontic composite appliance corresponding to the orthodontic composite appliance in the embodiment is as follows:
the semi-finished product comprises a male die 300 and the orthodontic composite appliance, wherein the male die 300 is provided with a die outer wall, the inner wall part 121 of the orthodontic brace 100 is opposite to the die outer wall, and the orthodontic connecting part 242 extends inwards from the inner side opening 132 and is connected with the male die 300.
