Torque indicator ratchet wrench for dentistry

A dental ratchet wrench for applying a known amount of torque to a fastener that is used in a dental prosthesis, comprising:

• a housing;
• a drive member located primarily within said housing, said housing and said drive member defining a first region therebetween;
• a tool receiving component for receiving a tool to exert torque on said fastener, said tool receiving component located primarily within said drive member, said tool receiving component and said drive member defining a second region;
• a torsion spring located within said second region, said torsion spring having one end connected to said drive member and the other end connected to said tool receiving component, a certain angular displacement of said one end relative to said other end producing a certain torque on said tool receiving component;
• a slip clutch located within said first region, said slip clutch causing said drive member to rotate with said housing when said housing is rotated in one direction, said slip clutch causing said drive member to rotate relative to said housing when said housing is rotated in the opposite direction;
• and
• torque indicators on at least one of said drive member and tool receiving component corresponding to predetermined torque values, said torque indicators progressively illustrating the amount of torque being exerted by said tool receiving component.

A dental wrench for applying torque to a fastener used in a dental prosthesis, comprising:

• a housing;
• a drive member located primarily within said housing;
• a tool receiving component coupled to and located adjacent to said drive member, said tool receiving component for receiving a tool to exert torque on said fastener, said tool receiving component including an ISO-type tool holder for holding a dental tool having an ISO-type latch;
• and
• torque markings representing corresponding torque values on at least one of said drive member and said tool receiving component.

A ratchet wrench for applying torque to a fastener, comprising:

• a drive member;
• a rotor coupled to and located adjacent to said drive member, said rotor for exerting said torque on said fastener;
• a ratcheting mechanism allowing said drive member to move said rotor in one direction;
• and
• a plurality of torque markings representing corresponding torque values on at least one of said drive member and said rotor, said torque markings progressively illustrating the torque that said rotor places on said fastener.
