Description

Toothless implant nail

Technical Field

The invention relates to the technical field of medical instruments, in particular to a toothless implant nail.

Background

The implant nail is also called implant, namely artificial tooth root, the manufacturing raw material of the implant nail is titanium metal, usually, the implant nail is implanted into the jaw bone through an operation, then the implant nail is connected with the dental crown of the implant after the wound is completely healed and the implant nail is stable.

The planting nail mainly plays a role in fixing and borrowing. The implant nail is usually used for correcting the serious deformity or bucking tooth, can prevent an implant from falling off, and can effectively prolong the service life of the implant. Or the implant teeth are made to the teeth, so that the occlusion relation of the teeth can be recovered, in addition, the teeth can be more tidy, and after the implant teeth are made, people do not need to eat excessively hard food in a short time, and the recovery of gum is prevented from being influenced. Such planting nails may function as a fulcrum. After the implant is implanted into the alveolar bone, the teeth can be rearranged by means of the force of the alveolar bone, so that the teeth become regular, the upper teeth and the lower teeth can be better occluded, and the eating effect is better.

Some existing planting nails are bound by tying wires, bent by arch wires or firmly adhered by adhesives, so that food residues of patients can be caused, and the using effect is influenced; other current planting nails adopt central bolt to fix the dental crown, and easy the taking place is become flexible and rotatory when using for a long time, leads to planting the tooth and drops, has designed a no tooth and has combined planting nail according to above-mentioned problem.
