Drawings

Fig. 1 is a schematic view of the structure of the comfortable type bow expander in use.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1: comfortable type ring curve expands bow ware, including base 1, expand bow spring 2, tongue 3 and maintenance device 4, base 1 is two, fixes respectively in the side of both sides molar, and maintenance device 4 is fixed mutually with base 1, and maintenance device 4 is corresponding with the molar, and the both ends of tongue 3 are fixed respectively on two bases 1, and the both ends that expand bow spring 2 are fixed mutually with two bases 1 respectively, and the 2 middle parts of expanding bow spring are equipped with U type circle 21, and it is located the rear side of tongue 3 to expand bow spring 2. The end parts of the bow-expanding spring 2 and the tongue spring 3 are fixed with the base 1 in a molding way.

When the appliance is used, the tongue 3 acts on the root of the front row of teeth, the thrust of the expansion spring 2 to both sides acts on the base 1 and is transmitted to the molars at both sides, so that the dentitions at both sides move towards the acting force direction of the expansion spring, and the effect of expansion correction is realized.

This comfortable type ring curve expands bow ware is moving the dentition of both sides to side after wearing, rather than being used for opening palatal centre joint, for current expand bow ware, overall structure is simpler, and the volume is littleer, and the wearing comfort level is higher, alleviates the foreign body sensation, the tooth interlock of being convenient for, gets and wears the convenience.

The bow-expanding spring 2 comprises a first adjusting part 22, the first adjusting part 22 is positioned on two sides of the U-shaped ring 21, the first adjusting part 22 is positioned between the base 1 and the U-shaped ring 21, and the first adjusting part 22 is U-shaped.

The U-ring 21 and the first adjustment portion 22 are formed as an integral structure. Wherein, the expansion bow spring 2 is formed by bending a stainless steel wire with the thickness of 1-1.2 mm, and meets the requirement of use strength.

In order to facilitate the pushing of the acting force of the U-shaped ring 21 to the two sides, the U-shaped ring 21 is gradually narrowed towards the opening, so that the transmission of the acting force is facilitated. Meanwhile, the elastic force of the U-shaped ring 21 can be adjusted by adjusting the bending degree of the first adjusting part 22, so that different bow expansion requirements can be met, and the U-shaped ring 21 is ensured to have enough bow expansion force all the time.

Two sides of the tongue 3 are provided with second adjusting parts 5, the second adjusting parts 5 are S-shaped, and the second adjusting parts 5 and the tongue 3 are of an integrated structure. The tongue 3 is also made by bending a stainless steel wire.

The second adjusting part 5 can adjust the thrust of the tongue 3 to the outside of the oral cavity, so that the tongue 3 always acts on the root of the anterior teeth.

The base 1 comprises a first matrix 11 and a second matrix 12, the first matrix 11 and the second matrix 12 are connected through a retention device 4, and the first matrix 11 and the second matrix 12 are respectively positioned at the inner side and the outer side of the molar. Wherein the surface area of the first substrate 11 is larger than the surface area of the second substrate 12. When the first basal body 11 and the second basal body 12 are worn, the lower part of the molar teeth and the gum part of a patient are tightly attached, the acting force of the bow-expanding spring 2 can be conveniently and well applied to the corresponding tooth row, and the correction function is realized. Wherein, the two ends of the tongue 3 and the two ends of the expansion bow 2 are respectively fixed in the first basal bodies 11 at the two sides, so that the transmission of the force is convenient and the wearing of the patient is convenient.

The fixing device 4 includes a first link 41 and a second link 42, both ends of the first link 41 are fixed to the first base 11 and the second base 12, respectively, both ends of the second link 42 are fixed to the first base 11 and the second base 12, respectively, and both ends of the first link 41 face opposite to both ends of the second link 42. The first connecting rod 41 and the second connecting rod 42 are both stainless steel wires, when the comfortable type loop expander is worn, the first connecting rod 41 is clamped on adjacent molars, and the second connecting rod 42 and the first connecting rod 41 are fixed in the same way. Through being equipped with first connecting rod 41 and second connecting rod 42, can improve the steadiness that first base member 11 and second base member 12 are connected, simultaneously for base 1 passes through the multiple spot to be fixed on the tooth, has guaranteed the normal use of comfortable type ring bending expansion bow ware, thereby reaches the orthotic effect.

The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept, and these all fall into the protection scope of the present invention.
