Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of heat for department of stomatology patient's upper jaw orthodontic treatment
Press mold magnetic force expands bow device and its manufacture method.
Background technology
For teenager's upper jaw transverse direction hypodevelopment or intraversion patient, the most common method of orthodontic treatment is upper jaw palate
Extension.Optical force is transferred to each bone structure of Maxillary region, causes bone remodeling by palate expansion technique by the load of maxillary teeth.
The effect of palate extension and expand force value size, action time and the retention time bent, the factor such as age of patient are closely related.At present
The extension of correction palate can be divided into quick palate extension (RPE) and palate extension (SPE) at a slow speed.
It is quick to return the method that extension (RPE) is clinically common expansion dental arch of maxilla.Due to easily being recurred after expanding bow, and
Cause it once using less, but start extensive use in clinic again in recent years.In RPE, it is more commonly used have Hass types,
Hyrax types and Arch bar splint type etc..The reinforcing mode of these three appliances is essentially identical, is usually reinforcing 2 times daily, sooner or later each
I times, rotation expansion bow helical spring 1/4 encloses every time or 1/2 encloses.RPE uses optical force as mediation more, can directly overcome Palatal suture biology knot
With joint efforts to open Palatal suture, but preferably used in youth Pubertal peak.It acts as the horizontal development for promoting maxilla, expand
Upper greatly frontal bone and arch width.
Palate extension (SPE) is typically to be connected to by the fixed bow device that expands of palatine on the anchorage tooth band of upper jaw both sides at a slow speed,
It is most common have four circle helical springs, it is W-shaped expand bow device, NiTi expand bow device and spring expand bow device and it is attached expand bow spring activity expand bow
Device.The expansion bow rate of about 0.5~1.0mm weekly can generally be produced by expanding bow device at a slow speed, expanded bow weight and be can reach 2oz.
Above two scheme there are it is respective the defects of：
It is quick to return extension (RPE) as reinforcing daily, therefore Orthodontic force accumulation can be made to expand Palatal suture to thousands of grams quickly
And tooth inclination is less, reach inclination of the bone amount increase more than tooth to greatest extent.More bone changes can be produced, palate top can be made
Become higher, Anchorage molar eruption becomes apparent from.But the larger optical force that upper jaw RPE is produced, has a certain impact tooth, while to larger
The necessity of optical force also has query.
On the contrary, to reinforce weekly once, Orthodontic force is more constant for palate extension (SPE) at a slow speed, no accumulation increases severely, so that reduction group
Liquid accumulation and bleeding are knitted, more meets physiology formation and the physiological reaction of bone.But SPE produces more dental arch and expands, and tooth effect is bright
It is aobvious, such as Sloped rotating of grinding one's teeth in sleep；All there is gap in the nearly all case palate relayings of RPE；And SPE only has the case Palatal suture of half
There is gap；RPE sagittal to, vertically to being revolved after also thering is more change, SPE then to produce more lower jaws.
Also there are all kinds of explorations that magnetic force is applied to palate extension at present, but there are structure to answer for existing various correction apparatus
Miscellaneous, manufacture difficulty is big, with high costs, short life, it is easy to wear the shortcomings that.
The content of the invention
It is an object of the invention to provide a kind of hot pressing film magnetic force to expand bow device and its manufacture method, with reference to hot pressing membrane technology,
Magnetic force correcting technology and structure, optimization design realize upper jaw orthodontic treatment, and manufacture is reduced while therapeutic effect is improved
Difficulty and cost, to solve to ask existing for traditional all kinds of correction palate expanding units proposed in the above background technology or scheme
Topic.
