Description
Technical field
The present invention relates to the micro-implant anchorage nail of a kind of correction, absolute anchorage can be provided for rescuing of malocclusion.
Technical background
1, traditional implant anchorage can meet the demand of correction absolute anchorage, is better than other anchorage.
Implant anchorage is considered to absolute anchorage and is applied to clinical, the anchorage that during retract anterior teeth, plantation nail provides is different from traditional anchorage, because pull strength does not impose on backteeth, produce backteeth reach hardly, the closedown of extraction of tooth space can all be completed by labial teeth adduction, therefore a large amount of labial teeths is produced far away middle mobile, be conducive to the face type obviously improving prolapse, implant site be generally mandibular first molar and the second premolars or upper lower jaw the or two grind one's teeth in sleep between Gen Jian alveolar ridge district, micro-implant anchorage nail at this position is mainly retract anterior teeth provides anchorage, implant some Vertical dimension and be positioned at mucogingival junction near attached gingiva region.
2, implant anchorage can meet the demand of absolute anchorage, but there is the problems such as inflammation comes off
Experiment finds that micro-implant anchorage nail great majority of loose or dislocation all exist micro-implant anchorage nail inflammation around, between the upper jaw second premolars and first molar, the expulsion rate of cheek lateral areas is especially higher, and this may follow closely with micro-implant anchorage the soft tissue injury that causes and the self-cleaning action of backteeth district is poor also has relation.The mucosa wound causing micro-implant anchorage to follow closely inflammation around divides two classes, and a class is traumatic ulcer, and mainly repeatedly being rubbed by anchorage nail and cheek mucosa causes.Another kind of, be the soft tissue infection occurred after implanting, time serious, even cause the redness of mucosa, visit the loose or dislocation of examining hemorrhage pyorrhea and anchorage nail.If enough dark in the clinical middle micro-implant anchorage nail implantation finding to tilt to implant, then head can oppress the gingival mucosa of implantation position, if implantation depth deficiency, can expose portion screw thread, make its curtailment in bone, and the screw thread exposed very easily forms bacterial plaque stagnant area again, the generation of both of these case all can increase and form the scorching risk of micro-implant anchorage nail around, thus causes micro-implant anchorage to follow closely unsuccessfully.The neck structure of micro-implant anchorage nail is also ensure one of its factor played a role, micro-implant anchorage nail is transitioned into open oral environment in this region from sterile bone environment, be vulnerable to the impact of bacterial plaque, thus traditional micro-implant anchorage nail is all designed to smooth neck structure, but smooth neck can increase the pressure of micro-implant to cortical bone, causes marginality bone resorption.
3, can the primary stability of micro-implant anchorage nail obtain successful key factor
The stability at micro-implant anchorage nail implantation initial stage obtains successful key factor, affect a lot of because have of primary stability, also important role is play in the primary stability that wherein pitch is followed closely at micro-implant anchorage, less pitch is conducive to planting nail being uniformly distributed of pressure in bone, and the stability of micro-implant anchorage nail is also better.Different pitch produces different helical angles, and pitch is larger, and helical angle is larger, and the input speed is faster, and the stability of micro-implant anchorage nail is poorer, and excessive or too small pitch is all unfavorable for the stability of planting nail.In addition, lower for bone density, the angle of elevation patient that cortical bone is thinner, can adopt micro-implant anchorage nail that diameter is thicker, to increase micro-implant anchorage nail surface and the contact area of sclerotin, obtain good primary stability.In addition, micro-implant anchorage nail implants point suitably near root of the tooth direction, under the prerequisite not injuring vital tissue, suitably reduces micro-implant anchorage nail implant angle, increase the parcel of micro-implant anchorage nail cheek side seam cortex as far as possible, be also conducive to the stability after increasing the implantation of micro-implant anchorage nail.
Summary of the invention
The invention provides the micro-implant anchorage nail of a kind of correction.This anchorage nail comprises anchorage nail head, anchorage nail cervical region and anchorage nail threaded portion.Anchorage nail head is made up of the solid rectangles of thick 2mm, a corner cut disappearance of the nearly cervical region of this cuboid follows closely the relevant position labelling special identifier of implanting instrument in anchorage, the inclined degree on this design and implantation place gingival mucosa surface adapts, avoid the geometric shape compressing gingiva on the surface of implantation body, cause mucosal inflammation, more be conducive to cleaning around anchorage nail, above anchorage nail head, constriction forms ligation head; Anchorage nail cervical region to wear gum portion profile smooth, long 2mm, surface has antibacterial biological coating, prevents bacterial plaque from being formed, reduces generation scorching around micro-implant, and prevention anchorage is followed closely and come off; Anchorage nail cervical region and anchorage nail head connecting portion are that mild arc line shaped designs, and are conducive to local clean; The threaded portion of anchorage nail is two sections, cortical bone section and spongy bone section, and cortical bone section is the close helicitic texture of 2mm, and remaining spongy bone section is for dredging helicitic texture, and this construction features is more conducive to the stability of anchorage nail, reduces the expulsion rate of anchorage nail.
