The invention discloses a residual root noninvasive dislocation device and belongs to a medical instrument. The residual root noninvasive dislocation device comprises a self-tapping taper thread body (1), a lengthening body (2) and a rotating portion (3). The self-tapping taper thread body (1), the lengthening body (2) and the rotating portion (3) are sequentially connected coaxially. The cross section of the rotating portion (3) is larger than that of the lengthening body (2). The residual root noninvasive dislocation device is used for pulling out a tooth or a residual tooth root and causes no injuries to an alveolar bone. The residual root noninvasive dislocation device is small and exquisite in structure, convenient to use and good in clinical effect.
Undesirable root is without wound dislocation device
The present invention relates to a kind of medical apparatus, in particular to a kind of for the nothing wound dislocation device of tooth body or undesirable root.
Exodontia is the most frequently used treatment technology of Stomatological Department. When corona and neck depart from root of the tooth, only leaving root of the tooth when pressing in groove, exodontia will become abnormal difficult. Present stage can only destroy part alveolar bone, then clamps undesirable root with pliers and extracts, or directly with chisel by root of the tooth and alveolus connect destruction after take out undesirable root. These two kinds of methods all can damage alveolus in various degree, not only bring bigger misery to patient, also can affect the healing of wound and the firm of implant. Particularly once being the patient of root canal, its undesirable root has lost activity, not only can hardening change crisp, also can stick together with alveolar bone, bring bigger difficulty to extracting of undesirable root.
It is desirable to provide a kind of undesirable root is without wound dislocation device, for extracting tooth or remain root of the tooth and do not cause any damage of alveolar bone, present configuration is exquisite, it may also be useful to convenient, clinical effectiveness is good.
Undesirable root disclosed by the invention is without wound dislocation device, comprise self-taped type taper thread body (namely conical surface arranges self-taped type screw thread), extension body, rotating part, described self-taped type taper thread body, extension body, rotating part coaxially connect successively, and the cross section of described rotating part is greater than the cross section of extension body.
The using method of the present invention: 1) extracting formation dislocation device place hole on tooth or root of the tooth, its method is taking the root mouth of pipe of root of the tooth as boring point, the Three Diamond pioneer being less than 2.0mm with diameter bores (≤1500 rev/min) major axis along canalis radicis dentis direction or root of the tooth to from the superficial to the deep entering tooth body, determining drilling depth with the length of tooth or root of the tooth, Formation Depth is the tapered hole of 8-10 millimeter; 2) the self-taped type taper thread body of device of atraumatic tooth extraction being dislocated directly screws in the tooth body tapered hole got ready along clockwise direction, it is tightened to one, the extension body and the rotating part that are connected with self-taped type taper thread body are exposed to intrinsic oral external, in order to knocking apparatus clamping; 3) the beak portion of upper jaw right angle root pincers is held on boundary place between the extension body of atraumatic tooth extraction dislocation device and rotating part, is close to rotating part surface; 4) to hold dental forceps position as upper jaw right angle root pincers retaining part between fulcrum, atraumatic tooth extraction dislocation device extension body and rotating part is for by force, the joint of right angle root pincers is the point of application, keep the direction consistent with root of the tooth major axis at once to make to be pulled out tooth or root of the tooth disengaging tooth socket at right moment percussion power that right angle root clamps that to add 10 on the point of application kilogram left with oral medical hammer, complete atraumatic tooth extraction art.
Preferably, the cone angle of described self-taped type taper thread body is 6 °.
Preferably, described extension body is right cylinder.
Further, described extension body is round platform, and described round platform upper surface is connected with self-taped type taper thread body, and it is 6 ° that round platform lower surface is connected the cone angle of round platform with rotating part.
Further, described rotating part is disk.
Preferably, the circumference face annular knurl of described disk.
Preferably, the circumference face of described disk arranges anti-slip tank, and described anti-slip tank is axially arranged, and anti-slip tank has nine, and nine anti-slip tanks are equidistantly arranged.
Further, the pitch of thread of described self-taped type taper thread body is 1.25mm.
Further, the screw thread groove of described self-taped type taper thread body is circular arc.
Preferably, the arc radius of described self-taped type taper thread body screw thread groove is 0.65mm.
Preferably, the bottom center of described rotating part is provided with blind hole.
Further, described blind hole diameter is 3mm, and blind hole depth is 3mm.
The present invention has following useful effect:
1. present configuration is exquisite, can combine closely with tooth;
2. adopt the present invention to pull out undesirable root, alveolar bone can not be damaged;
3. adopting the present invention to pull out undesirable root, step is few, easy to operate, time saving and energy saving.
