Mechanical dental articulator having adjustable claming feature and method of use

Image Number 3 for United States Patent #5743733.

A dental articulator is claimed which comprises an upper frame, a lower frame, a positioning member for positioning the upper frame, and a clamp for securing the positioning member and fixing the upper frame in position. The upper frame includes a hinge such that a mounting portion of the frame can be moved through basic opening and closing mandibular movements. The mounting portions of the upper and lower frames are configured to accept for fixation upper and lower dental models respectively. The positioning member is coupled at one end to the upper frame for pivotal movement, such that an inclination of the upper frame relative to the lower frame can be effected. The positioning member is configured and dimensioned to position the upper frame in opposing relationship with the lower frame such that an articulation of upper and lower dental models can be effected. The other end of the positioning member is free to allow manual adjustment of the upper frame relative to the lower frame, to effect a proper functional occlusion of the dental models. The clamp for the positioning member is disposed adjacent to the lower frame.
