Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to one kind is used for department of stomatology patient upper jaw orthodontic treatment
Hot pressing film magnetic force expand bow and front tractor.
Background technique
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 the factors such as force value size, action time and the retention time of expansion bow, the 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.
Quickly returning extension (RPE) is reinforcing daily, therefore can make Orthodontic force accumulation to thousands of grams quickly, expands Palatal suture
And tooth inclination is less, reaches bone amount to the maximum extent and increases the inclination for being greater than tooth.More bone variations can be generated, palate top can be made
It gets higher, Anchorage molar eruption becomes apparent from.But the biggish optical force that upper jaw RPE is generated, has a certain impact to tooth, while to larger
The necessity of optical force also has query.
Palate extension (SPE) is that reinforcing is primary weekly at a slow speed, and Orthodontic force is more constant, and no accumulation increases severely, to reduce tissue fluid
Accumulation and bleeding, the physiology for more meeting bone is formed and physiological reaction.But SPE generates more dental arch and expands, and tooth effect is obvious, example
It such as grinds one's teeth in sleep Sloped rotating；All there is gap in the nearly all case palate relaying of RPE；And SPE only has the case Palatal suture of half to occur
Gap；RPE sagittal to, vertically to also there is more variation, SPE then generates more lower jaw back spins.
IS-One Group III plate bite, being commonly called as " Bao Tian " is a kind of clinical common patho-occlusion of correction, disease incidence compared with
It is high.IS-One Group III plate bite patient continues to grow forward during growth and development with lower jaw, and deformity can be aggravated gradually, by
Tooth, functional gradually development are bone, seriously affect the jaw of patient and develop, oral cavity function and face it is beautiful.It is sent out in growth
During educating, the increment and the direction of growth of cranium Snorer can be influenced by changing environmental factor.
It is a kind of clinically for early stage field III tooth, functionality, bone plate bite frequently with two kinds of appliance
It is treated for chin pocket, Face-mask therapy device etc., infant is often because beautiful, wearing time is limited, and impact effect；Another kind is
Intraoral to wear with device, therapeutic effect is slow, substantially prolongs the treatment cycle of patient, and rectification effect is unobvious.
