As can be seen at once, it is with one of these Instrument may even be possible., With the most careful Handling cracked SSafonwuraeln either completely or at least like that pull out far 9 so that the Sisasel parts afterwards comfortably and can be safely gripped with a pair of pliers.

An example of the invention is described below described on the basis of the accompanying drawing «, In the drawing show:

FIG. 1 shows a greatly enlarged: side view of an instrument _{g according to the invention}

Figure 2 shows a section along the line II-II of Figure I ₉

Figure 3 a Βοτη sum insertion into the hole in the handle and

FIG. 4 shows the use of the instrument.

The instrument shown in Figures * 1 and 2 has

a shaft designated as a goose with 1, which is provided with a conical, sawtooth-shaped thread la ₉ and a head 2 arranged as a handle on the thicker end © of the shaft «, 2to bores into which the pin 3 shown in FIG. 3 can be inserted up to the shoulder 3a. The taper angle of the thread is 3s'? the screw tip is formed by a cone Ib with a cone angle of approx. 30 ° »

The total length of the instrument must not exceed 4 esa; It is advantageous, for example, 3 esa - J ₉ 5 cm ₈ so that the instrument can be inserted far back into the patient's mouth _{and used} to remove the roots of a wisdom tooth.

FIG. 4 shows the use of an instrument according to the invention. In the jawbone between two yawns 5 and 6 is the divided sausage 7 of a tooth; As iaan © hn © further, it is so deep as a tooth socket that it cannot be grasped with pliers "Now the ± n of Figure 1 is shown =" © The instrument is screwed into an Iforaelkasial 7a by hand "Venn the instrument can not be further rotated csehr, infected süasa the pin 3. 3 ** the bore 2b ₀ and then one can with the necessary care continue to turn ₉ to the screw isn root canal sitting "because it is itself conically ₅ thereby also the conical © screw with more than τιητ one

The turn is well anchored. Once the screw sitst in the su-removing tooth root "it can be pulled out by train on the instrument from DEAS jaw _e Wosu under certain circumstances the help of serving as a lever bar, necessary ₉ is abgestütst at a passonden tooth and acting on the pin 3 .
