Description

Acute angle dental handpiece for middle-low impacted third molar extraction operation

Technical Field

The utility model relates to a dental handpiece technical field, concretely relates to acute angle dental handpiece of middle and low position impacted third molar extraction operation.

Background

In the existing stage, the dental handpiece for removing the impacted third molar is a high-speed dental handpiece for the impacted third molar with an angle of 45 degrees and is matched with a long-lathe split drill (25mm), and a dental crown and a dental root are cut and separated and then are respectively taken out. In the actual third molar extraction operation, because the third molar is deeply arranged in the molar rear cushion, and the influence of the limitation of the patient's mouth opening degree, the influence on the jaw teeth, the limited drawing degree of the buccal labial margin, the shielding of the lifting and supporting of the lower jaw and the like is added, the dental handpiece is usually inserted in the way that the handpiece handle part is parallel to the mandibular dentition or forms a small angle, so that a doctor with insufficient experience cannot correctly master the cutting direction, and the teeth separation cannot completely and correctly remove the resistance or damage the surrounding tissues.

For the doctor with abundant experience, although the cutting tooth dividing direction can be grasped, because the special dissection position of the third molar is blocked, in the operation, the 45-degree mobile phone is blocked by the involuted teeth and the adjacent teeth, and the mouth-lip traction opening degree and the mouth opening degree of the buccal side of the patient are limited, the car needle cannot achieve the ideal cutting direction. The formed tooth dividing cutting line is often from a high position at the middle to a low position at the far middle, thereby bringing about the obvious disadvantage that the cut crown is in a state of small upper part and big bottom part, even though the tooth body is cut off. Because the adjacent teeth and the tooth roots are blocked, the tooth crowns with small upper parts and large lower parts still cannot be dislocated smoothly, so that bone tissues have to be cut or removed again, the cutting amount is increased, and a series of problems of prolonging of operation time, increasing of operation difficulty, increasing of operation uncertainty, increasing of wounds suffered by patients and the like are brought along.
