Disposable torque wrench for dental components

A torque wrench for a dental implant component, comprising:

• a single integral shaft having a first end, a second end, and a middle portion having an undercut therein, said first end having a first engaging means for engaging coupling means coupled to said dental implant component upon which a torque is to be applied, wherein said shaft is constructed of a preselected material and dimensioned to a first preselected cross-sectional thickness, and said undercut being located at a preselected location along said shaft and undercutting said shaft to at least one preselected cross-sectional thickness such that said shaft deforms substantially and noticeably without breaking at said undercut when a predetermined torque is applied through said shaft to said dental implant component.

A torque wrench for a dental implant component, comprising:

• a single integral shaft having a first end, a second end, and a middle portion having an undercut therein, said first end having a first engaging means for engaging said dental implant component, said first engaging means having one of an outer surface which is hexagonal in cross-section and an indentation which is hexagonal in cross-section, wherein said shaft is constructed of a preselected material and dimensioned to a first preselected cross-sectional thickness, and said undercut being located at a preselected location along said shaft and undercutting said shaft to at least one preselected cross-sectional thickness such that said shaft deforms at said undercut when a predetermined torque is applied through said shaft to said dental implant component, said undercut increasing in width as it increases in depth and then decreasing in width as it decreases in depth.
