A dental implant angle measurement device for measuring angular difference includes a reference member that can be engaged with a reference dental component. An elongate member is attached perpendicular to the reference member and a measuring member is movably positioned along the elongate member. The measuring member can be aligned with a target dental component and further includes a base member and an angular indicator. The angular indicator can have gradations and indicia to indicate an angular difference between an axis passing through the reference dental component and an axis passing through the target dental component that the measuring member is aligned with. The target dental component is positioned in the mouth of the patient or in a cast. A stopping member is also positioned with the elongate member to restrict movement of the measuring member in relation to the elongate member.
