Principles and practice of operative dentistry . Superior third molar, extracting, separating, and excising forceps. (Dr. Stellwagen.) double wedge of the jaws thus starts the tooth from its alveolus and thedepression of the handles carries the crown backward, dislodging it fromits alveolus. Figs. 697 and 698 represent instruments designed by for the combined purpose of extracting superior and inferiorthird molars and excising and separating roots. The principle involvedin their application is the same as in the Physick Inferior third molar, extracting, separating, and excising forceps. (Dr. Stellwagen.) The inferior third molars have usually single roots which curve back-ward, but occasionally the roots are multiple. Under these circumstancesthey can usually be extracted with the forceps shown in Fig. 699, but 44 690 OPEEATTYE DENTISTRY. when the root is curved it becomes necessary to employ the Physickor Stellwagen forceps. The instrument is applied as for the removal ofthe superior third molars, and the handles are closed and depressed. Thisstarts the tooth from its alveolus, tips it backward, and dislodges it. Caremust always be exercised in the use of these forceps not to injure the toothin front which acts as the fulcrum. If these instruments are carelessly Fig. 699.
