Fig. 18-36 are various structural diagrams of the invisible appliance with the spherical latch, and fig. 18 is an expanded schematic diagram of the invisible appliance with the spherical latch, wherein it can be seen that the invisible appliance with the spherical latch is provided with a plurality of membrane blockmain units 1, the membrane blockmain units 1 are arranged according to the arrangement shape of teeth, the membrane blockmain units 1 comprise membrane block tops 101 and membrane blockperipheral coating parts 102, the membrane blockperipheral coating parts 102 are smoothly connected with the peripheries of the membrane block tops 101,membrane block cavities 103 are formed inside the membrane block tops 101 and inside the membrane blockperipheral coating parts 102, themembrane block cavities 103 are provided withspherical latches 9 at the gaps between the connected teeth, and thespherical latches 9 are protrusions extending out of the inner walls of themembrane block cavities 103 in the direction of themembrane block cavities 103; as can be clearly seen from the cross-sectional view of fig. 19, thespherical clamp 9 is a protrusion extending out of the inner wall of the membrane blockinner cavity 103 in the direction of the membrane blockinner cavity 103, and the protrusion is a circular protrusion or a semicircular protrusion. When a larger fastening force is required to be provided between the membrane blockmain body unit 1 and teeth to be corrected, a circular bulge can be adopted, the circular bulge means that the bulge which leaks on the inner wall of theinner cavity 103 of the membrane block is larger, the large bulge can clamp the bulge in gaps between the teeth more tightly, and the membrane blockmain body unit 1 can be more firmly fixed and can generate larger correction force to realize correction of the teeth with larger deformation, and a plurality of invisible membranes are not required to be adopted, so that correction of the teeth with large deformation can be realized by adopting one set of invisible correction device, when a patient comes, the patient can be easily corrected, and for a doctor, the operation of replacing the membranes is not required to be frequently provided, the correction cost of the patient is low.

The setting of thespherical card 9 in this embodiment is totally located inside theinner cavity 103 of the diaphragm, and the outer side of the diaphragm of the invisible appliance is a smooth surface, so that a patient does not feel unsmooth when wearing the appliance.

As can be seen from fig. 18, the circular protrusion or the semicircular protrusion is an inverted cone extending from the outermost surface of theinner cavity 103 of the membrane block to the inner direction of theinner cavity 103 of the membrane block, and the circular protrusion or the semicircular protrusion of the inverted cone can meet the conical shape of the tooth, and is tightly fitted and large in contact area.

Fig. 31 shows that the ball-shapedcard 9 comprises a ball-shapedcard head portion 901 and a ball-shapedcard contraction portion 902, the height of the protrusion of the ball-shapedcard contraction portion 902 is smaller than that of the ball-shapedcard head portion 901, the ball-shapedcard contraction portion 902 can better protect the gaps between teeth, because the cross section of the ball-shapedcard contraction portion 902 is smaller, when the ball-shapedcard head portion 901 is clamped in the gaps between the teeth, the membranemain body unit 1 can be firmly fixed, the gap between the teeth in the upward direction is small, thus, the gap between the teeth in the upward direction can be protected by the small size of the ball-shapedcard contraction portion 902, the increase of the gaps between the teeth caused by long-time fixing can not occur, and after the teeth are corrected.

As can be seen from fig. 26 and 28, the ball-shapedclip 9 is only a semi-circular ball-head protrusion which leaks outside, and the ball-shapedclip portion 901 and the ball-shapedclip contraction portion 902 are not arranged, so that a circular ball-head protrusion which leaks outside can be more simply clipped inside the gap between the teeth, and the ball-shapedclip 9 and the teeth can be clamped, the diameter of the ball-head of the simple semi-circular ball-head protrusion is generally 0.2mm-0.8mm, and the sizes of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm and the like can be selected according to the size of the gap between the teeth and the size of the gap between different combining parts between the teeth, so that the simple semi-circular ball-head protrusion is very suitable for patients with small gaps between the teeth, is very simple to use, has a very good effect, and can achieve the purpose of correction through the.

As can be seen in fig. 32, a sphericalclip transition portion 903 is arranged between thespherical clip portion 901 and the sphericalclip contraction portion 902, the sphericalclip transition portion 903 is generally smaller than the section size of thespherical clip portion 901, and thus, the sphericalclip transition portion 903 is arranged between the spherical clip portion and the spherical clip contraction portion, which can meet the requirement of a patient with a large tooth gap from top to bottom, thespherical clip portion 901 is mainly fixed at the root of the tooth gap, and the sphericalclip transition portion 903 plays a role in assisting in fixing the membrane blockmain unit 1, so that the membrane blockmain unit 1 cannot move when the patient wears the membrane block main unit for a long time, and the expected correction purpose can be achieved.

Fig. 23-fig. 30 are various schematic diagrams mainly showing that the sphericalclamping head portion 901 or the sphericalclamping transition portion 903 leaks outside theinner cavity 103 of the membrane block, and the design mainly and completely leaks the sphericalclamping head portion 901 or the sphericalclamping transition portion 903 outside theinner cavity 103 of the membrane block, so that the structure is suitable for correcting the use of a patient with small tooth deformation, because when the sphericalclamping head portion 901 leaking outside theinner cavity 103 of the membrane block clamps teeth to be corrected, a certain correcting force can be provided, and a larger correcting stress is not required to be provided by the surroundingcoating portion 102 of the membrane block, so that the correcting requirement of the teeth with small deformation can be met. And when the sphericalcard transition portion 903 leaks outwards, through the design of this kind of sphericalcard transition portion 903, can improve the joint strength of sphericalcard head portion 901 anddiaphragm top 101, avoid the fatigue deformation that the long-time use ofspherical card 9 produced, can guarantee the closely combined of diaphragmmain part unit 1 and the tooth that needs to be rescued simultaneously again, wear for a long time, can not lead to the tooth to rectify and reach unexpected purpose because of taking place to remove.

The number of thespherical clamps 9 arranged at the gap position between the connected teeth of the pellicleinner cavity 103 of one or more pelliclemain body units 1 in the arrangement of the pelliclemain body units 1 is 1-4, and in any implementation structure in fig. 15-17, it can be seen that the number of thespherical clamps 9 arranged at the gap position between the connected teeth of the pellicleinner cavity 103 of the pelliclemain body unit 1 is 4, so that the teeth to be corrected can be well fixed, and unexpected movement caused by long-time wearing can be avoided; of course, 2 or 3spherical clips 9 can be arranged in the inner cavity of the membrane block according to the shape and the degree of deformation of the teeth, so that the purposes of fixing the teeth and correcting can be met, and the treatment and correction scheme is simplified.
