A device for detaching a tooth root. The device comprises: a lead screw having a threaded point for screwing into the tooth root, and a threaded shaft; a pivoting member including a bore through which the lead screw passes, the lead screw being retractable through the bore by rotational engagement of a threaded member with the threaded shaft of the lead screw; and a platform for supporting the pivoting member such that the lead screw is able to pivot relative to the platform, The lead screw includes a locking surface for preventing rotation of the lead screw during rotational engagement of the threaded member with the threaded shaft.

Pincers for removing residual dental roots by the application of a contrary force on the mandible and maxilla on a pre-fixed screw. It is constructed in such a manner as to enable the strength of the operator 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, thereby preserving the underlying bone structure and facilitating implant osseointegration. Likewise the device can be easily sterilized and assembled/dismantled easily because of the small number of moving parts. Further, there is 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.

Embodiments of the present disclosure are directed to apparatuses and methods for pre-conditioning an extraction site for dental implantation. In one implementation, a method for pre-conditioning an extraction site for dental implantation includes providing a vibrational dental device configured to vibrate at a frequency higher than about 20 Hz. The method further includes providing instructions for mechanically vibrating, using the vibrational dental device, a tooth at the extraction site for about a predetermined period of time daily over a treatment period before extracting the tooth. The mechanical vibration may prepare the extraction site to be in a healthier condition for receiving an implant.

An object of the present invention is to provide forceps for removing a dental implant fixture, in which pinching portions securely hold a fixture to remove the fixture implanted in an alveolar bone, and thus to prevent the pinching portions from slipping out of the fixture. Forceps for removing a dental implant fixture according to the exemplary embodiment of the present invention include: a pair of handles; coupling portions extended from the handles, crossed, and hingedly coupled; pinching portions connected to the coupling portions; and holding pieces protruding from ends of the pinching portions in a direction toward a center of a dental implant fixture and each having an arc corresponding to at least a part of an outer circumference of the fixture so that the holding pieces are inserted into a trough of a threaded portion formed on the outer circumference of the fixture.

A dental instrument is configured to reduce user discomfort and increase control over the surgical edge of the instrument. The invention further discloses a dental instrument having a replaceable blade

An apparatus for grasping an object includes a base having a cylindrical wall, a circular plate attached to the base, and a screw configured to move a second section with respect to a first section of a circular plate. The circular plate includes the first section having a first face and the second section moveable with respect to the first section and having a second face opposite the first face. The first face and the second face each have at least one recess aligned to create at least one opening for grasping the object when the first face and the second face are brought into proximity with each other. Also disclosed is a method for grasping an object using the disclosed apparatus.

Provided are a tooth extraction auxiliary tool and the like which can reduce a burden on a tooth serving as a tooth extraction target, an alveolar bone at this tooth extraction target site, and/or adjacent teeth. A tooth extraction auxiliary tool 1 having a first auxiliary substrate 11 and a second auxiliary substrate 12 is used. The first auxiliary substrate 11 is inserted into a recessed portion X0 formed in a tooth X2, and a hot melt adhesive M is injected. In a state where the tooth extraction auxiliary tool 1 is firmly fixed to the tooth X2 by the solidified hot melt adhesive M, the second auxiliary substrate 12 is gripped by fingertips of an operator, and the tooth X2 is pulled out from a gum X1 while the tooth X2 is twisted.
