Description

Invisible tooth socket, extraoral arch matched with invisible tooth socket and invisible orthodontic extraoral arch system with invisible tooth socket

Technical Field

The utility model relates to a tooth correction device, in particular to an invisible tooth socket, which is matched with an extraoral arch and an invisible correction extraoral arch system with the extraoral arch.

Background

Compared with the traditional fixed correction technology, the bracket-free invisible correction technology has the advantages that the correction device is formed by processing medical resin films, and correction devices such as belt rings, brackets, arch wires and the like for fixing the correction device are omitted, so that the bracket-free invisible correction technology is called as a bracket-free technology; the orthodontic appliance processed by the transparent resin film is worn in the mouth and is not easy to be discovered, so the orthodontic appliance is called as invisible, the bracket-free invisible orthodontic appliance achieves the aim of orthodontic tooth through continuous small-range tooth movement, and compared with the traditional orthodontic appliance, the bracket-free invisible orthodontic appliance has the advantages of attractive appearance, comfort, contribution to oral hygiene maintenance and the like.

However, non-extraction early correction for mild maxillary protrusion deformity; the traditional appliance can adopt an extraoral arch to assist in pushing and grinding teeth backwards, so that the upper anterior teeth are retracted integrally to achieve the purpose of correction; the correction is carried out by only depending on the bracket-free invisible appliance, which easily causes the inclination and the forward movement of the upper labial margin when the molar is pushed backwards, and the preset correction target is difficult to achieve. The forming process of the bracket-free invisible appliance is limited, so that the external force of the mouth is difficult to be directly introduced into the bracket-free invisible appliance system, and the out-of-mouth bow and the bracket-free invisible appliance are difficult to be organically combined. Some researches for combining external force of mouth with a bracket-free invisible appliance to realize traction appear in recent years, and the traction on the bracket-free invisible appliance is realized mainly by the following modes:

(1) some incisions are made at the edge of the invisible appliance to form a shape capable of being hooked, and the rubber band is directly hung on the incisions to achieve the traction effect. However, in the method, the continuity of the edge of the invisible appliance is damaged, so that the area of the invisible appliance wrapping the teeth is reduced, and the correction effect is indirectly influenced; meanwhile, the edge of the incision is tilted due to the direct action of the rubber band on the incision, so that the invisible appliance is deformed to influence the correction effect, and the oral mucosa of a patient is easily damaged.

(2) An incision capable of accommodating the traction piece is cut at the edge of the invisible appliance, so that the traction piece can be conveniently pasted on the teeth and is not contacted with the invisible appliance, but the mode can reduce the integral wrapping property of the invisible appliance on the teeth, and the correction effect is indirectly influenced; meanwhile, the traction piece is stuck on the tooth surface and is not contacted with the invisible orthodontic appliance, so that the action site is the tooth where the traction piece is located instead of the whole dentition, and the traction piece can possibly cause unexpected direction movement on the tooth.

(3) The method is characterized in that a traction hook is arranged on the invisible appliance, for example, the traction hook is adhered to the surface of the invisible appliance, and the traction device is adhered to the invisible appliance in a chemical bonding or hot melting mode; some have designed the towing hook in two parts by making a hole in the invisible appliance and snap the two parts of the towing hook together after passing the towing hook through the hole in the invisible appliance. For example, the chinese patent application CN111297495A discloses a traction hook added beside a bracket-free invisible appliance chair, which comprises a traction part and a connection part, wherein during assembly, a hole is drilled on the bracket-free appliance by using a mechanic pliers, and during assembly, a connection column of the connection part is made to pass through the hole drilled on the bracket-free appliance, so that the connection column and the connection hole on the traction part are in interference fit. However, the following problems still exist in the practical application of the traction mode:

a, punching holes at the traction position of the bracket-free orthodontic appliance can damage the integrity of the bracket-free invisible orthodontic appliance, influence the coating effect of the bracket-free invisible orthodontic appliance on teeth and cause the limited movement of the teeth at the traction position;

b, the traction hook is of a split structure, but because the traction hook is made of the same material as the bracket-free invisible appliance, when the traction hook is subjected to a larger external force, the traction part and the connecting part are easy to deform and separate, the bracket-free invisible appliance cannot be pulled, so that the bracket-free invisible appliance cannot be subjected to a larger external force, and the correction effect is poor;

c, the inner connecting sheet adopts a sheet closely attached to the orthodontic appliance, but the traction part can deform after being stressed, so that the inner connecting sheet cannot well transfer the external force applied to the stressed column to the whole bracket-free orthodontic appliance, and the effect is weakened due to overlarge stress; in addition, for the prerequisite of realizing protecting as far as correcting the ware, reduce the influence of making a hole to the ware is rescued to no support groove, the aperture of its hole of making should minimize, the spliced pole that leads to connecting portion is less with the contact surface that the ware was rescued to no support groove, and pull through having the columnar hook that pulls, the slope takes place for its spliced pole atress easily, can act on after the spliced pole slope on the ware is rescued to no support groove, make easily that no support groove is rescued the ware and take place deformation and lead to causing harmful effects to other teeth.

d, if the mouth external arch is connected through the traction hook, the foot hook of the mouth external arch is hung on the stress column, and the stress column is rod-shaped, so that the force application direction of the mouth external arch can not be positioned, the force application direction of the mouth external arch acting on the bracket-free appliance can only be set by adjusting the inclination angle of the mouth external arch, and then the inclination angle of the mouth external arch is fixed through the high-position traction head cap; however, the high-position traction headgear may be loosened when being worn on the head of a patient, and it is difficult to precisely control the force application direction of the extraoral traction force.

To the combination of extraoral arch and stealthy appearance ware, adopt at present more install tubular structure on stealthy appearance ware, then insert the bow foot grafting of extraoral arch in tubular structure, for example: the Chinese patent application CN110063801A discloses an invisible appliance, wherein the buccal side surface of a dental lamina of the invisible appliance is connected with an outer tube, an extraoral traction bow is made of metal wires, and the inner end of the mouth of the extraoral traction bow is inserted into the outer tube. However, the mode that the foot of the extraoral arch is inserted into the tubular structure is adopted, the contact surface between the extraoral arch and the tubular structure and between the tubular structure and the invisible orthodontic braces is smaller due to the limit of the structure, and the contact surface is mostly single point or linear contact, so that the deformation caused by the overlarge local stress of the invisible orthodontic braces is easily caused, the unexpected orthodontic effect is caused on other teeth, and the final orthodontic effect is influenced. In addition, in the chinese patent application CN110063801A, the extraoral arch is not a whole, so that the imbalance of the two-side stress in the three-dimensional direction is easy to occur, the control of the (occlusal) plane is not good, and the control of the symmetry of the dental arch is not good; and the oral arch is connected with the dental laminates positioned on the upper jaw facing and the lower jaw facing, the acting force is not directly acted on the molar area, and the molar is pushed to go far and the effect of inhibiting the maxilla from moving forward is not good.

The term "occlusal" in this text is a term of professional vocabulary in oral medicine, English is oclusion, and the term "occlusal" is a left part and a right part of a character, and the character cannot be found in a common character library, so that the term "occlusal" is written separately.
