摘要：
The invention relates to pincers for removing residual dental roots by means of the application of a contrary force on the mandible and maxilla on a pre-fixed screw, applicable to the area of health, in dentistry. It is constructed in such a manner as to enable the strength of the operator (preferably, a dentist) to be multiplied and the final movement of the pincers to be reduced. The operator will need to apply minimal force and thus the procedure becomes simple and safe, without the risk of accidents caused by excessive movement of the force, thereby preserving the underlying bone structure and facilitating implant osseointegration. Likewise, because the pincers are simple in terms of their construction, the present utility model can be easily sterilised just like any other instrument used by dentists, and can be assembled/dismantled easily on account of the small number of moving parts. In addition to these advantages, there is furthermore no need for the mouth to be opened so widely, which results in less movement and less trauma caused by excessive opening of the patient's mouth, and it adapts to the irregular profile of support on the dental arch. Operation thereof is simplified and requires only the pre-fixing of the screw into the tooth or root for immediate use of the pincers. It may be adapted to pre-existing pins and screws by means of adaptors.L'invention concerne une pince pour enlever des racines dentaires restantes par application d'une force contraire dans la mâchoire et le maxillaire sur une vis pré-fixée, trouvant une application dans le domaine de la santé, en odontologie.
