摘要

TECHNICAL PROVISION INTRODUCED IN TOOL FOR EXTRACTION OF UPPER CENTRAL INCISIVE TEETH OF WISTAR RATS. The present invention patent relates to the technical provision introduced in an instrument for extracting upper incisors from wistar rats, which refers to a clamp to be used by different areas of dentistry, especially endodontics, who wish to research and have the need to perform extraction of upper incisor teeth from wistar rats. The clamp consists of an elongated piece with two large, firm rods that when pressed together. The forceps are characterized by the fact that their jaws (2) are completely modified to adapt perfectly to the size and anatomy of the upper incisor tooth of Wistar rats. The jaws (2) were curved, each according to the respective buccal and lingual curvature of the tooth. In the internal part of the modifiers (2), compensatory wear was performed to adapt perfectly to the curved nuances of the vestibular and palatal parts of the upper central incisor tooth of the rat. In addition, the rod (1) curved and the incisor of the rat was modified in its tip, being shorter than the tip that adapts to the vestibular part. The extractor instrument of upper incisors of wistar rats as an innovative invention, makes possible and facilitates the accomplishment of many researches in the dental area, with great safety to the animal's life, a very important question also in ethics for the use of animals.
