Abstract
A support device or post for fitting into an implant implanted into a patient which is configured to support a dental prosthesis is provided. An upper portion of the post, in one embodiment, has external screw threads for coupling a healing cap. The upper portion of the post may be removed or broken away at a weakened portion or constriction. The support device has a collar which can define various heights or diameters. The support device can be positioned in the implant by mating screw threads with the support device being torqued to a predetermined torque, preferably using a torque wrench which can be set using a non-variable, preferably gravity-based, standard.
Claims7
A device usable for calibrating a torque wrench with a ratchet head which is adjustable to provide a range of torque settings, which comprises;
- a frame;
- a beam member pivotally connected to said frame at a pivot axis;
- a weight coupled to the beam member and movable along a path having a component substantially parallel to the beam member for setting a desired torque level;
- an arm member having upper and lower ends;
- a gear connected to said beam at said pivot axis;
- said arm member having a gear-engaging surface for rotating said gear, the arm member pivotally attached to the frame;
- and
- a projection coupled to said arm member for receiving the ratchet head of the torque wrench so that rotation of said projection rotates said arm and said gear, lifting said beam member if said ratchet head is adjusted to a torque setting at least equal to said desired torque level.
A method for calibrating a torque wrench with a ratchet head which is adjustable to provide a range of torque settings, which comprises:
- providing a calibration device having a frame, a beam member pivotally connected to said frame at a pivot axis, a weight coupled to the beam member and movable along a path having a component substantially parallel to the beam member, an arm member having upper and lower ends, and a gear connected to said beam at said pivot axis, said arm member having a gear-engaging surface for rotating said gear, the arm member pivotally attached to the frame and a projection coupled to said arm member for receiving the ratchet head of the torque wrench;
- moving said weight along said path to a position establishing a desired torque level;
- adjusting said ratchet head to a first low-torque level;
- applying said ratchet head to said projection;
- rotating said torque wrench, without substantially lifting said beam;
- adjusting said ratchet head to increase the torque setting;
- rotating said torque wrench to lift said beam if said ratchet head is adjusted to a torque setting at least equal to said desired torque level.
A device usable for calibrating a torque wrench with a ratchet head which is adjustable to provide a range of torque settings, which comprises:
- a frame;
- pivoting means connected to said frame at a pivot axis;
- non-variable means coupled to said pivoting means and movable along a path having a component substantially parallel to the pivoting means for setting a desired torque level;
- means for receiving the ratchet head of the torque wrench;
- means for at least indirectly coupling said means for receiving to said pivoting means so that rotation of said means for receiving pivots said pivoting means if said ratchet head is adjusted to a torque setting at least equal to said desired torque level.
