— Six methods for active and passive recording of retruded position of the mandible were compared in an investigation carried out on 10 male volunteers, aged 22 to 27. The position of the mandible was recorded with the intraoral graphic method. The precision of the recording of the retruded position was highest when recorded by passive hinge movement, and lowest when recorded by active hinge movement and active retrusion from habitual occlusion. No differences in the anteroposterior position of the mandible in the retruded position were found between the active and passive recordings with the exception of the socalled “moderate chin guidance” which resulted in a more anterior mandibular position than the other methods, but still in the retrusive area, i.e. posterior to habitual closure.
