Abstract
A dental instrument comprising a grasping device in the form of a tweezer member having a finger receiving ring detachably connected to one of the legs of the tweezer member is disclosed. The instrument is used for holding and inserting a Cerec inlay, manufactured by a dental Cerec machine, in a tooth undergoing a restorative procedure. The instrument may further include a threaded axle which coacts with each leg of the tweezers and protrudes from one of the legs. The instrument may also further include a plunger mechanism which facilitates the insertion of an inlay in a prepared tooth cavity.
Claims28
A grasping device comprising:
- a tweezer member having a pair of mutually spaced legs extending resiliently from a common base and terminating at their distal ends in cooperatively arranged gripping segments;
- means defining a socket extending laterally from one of said legs;
- a finger receiving ring;
- and
- connecting means protruding from said ring, said connecting means being removable from and insertable in said socket to thereby accommodate attachment and removal of said ring to and from said tweezer member.
A grasping device comprising:
- a tweezer member having a pair of mutually spaced legs extending resiliently from a common base and terminating at their distal ends in cooperatively arranged gripping segments;
- an adjustment mechanism coacting with each of said legs to adjust the distance between said gripping segments;
- a finger receiving ring detachably connected to one of said legs;
- and means for detachably connecting said finger receiving ring to said tweezer member.
A grasping device comprising:
- a tweezer member having a pair of mutually spaced unequal length legs extending resiliently from a common base and terminating at their distal ends in cooperatively arranged gripping segments, said gripping segments extending upward each at a different angle;
- a threaded axle;
- a knob capable of forward and backward movement along said threaded axle such that said knob rotates to adjust the distance between said gripping segments;
- a detachable finger receiving ring;
- and
- means for detachably connecting said finger receiving ring to said tweezer member.
A grasping device comprising:
- a tweezer member having a pair of mutually spaced unequal length legs extending resiliently from a common base and terminating at their distal ends in cooperatively arranged gripping segments, said gripping segments extending upward each at a different angle;
- semi-spherical clenching segments disposed at the ends of the gripping segments;
- a threaded axle;
- a knob capable of forward and backward movement along said threaded axle such that the knob can be rotated to adjust the distance between said gripping segments;
- a detachable finger receiving ring and means for detachably connecting said finger receiving ring to said tweezer member;
- and
- means for determining the amount of pressure that can be applied to said tweezer member when said tweezer member is grasping a component.
