Fig. 2From: Antero-posterior mandibular position at different vertical levels for mandibular advancing device designPosition of lower incisor in relation to upper incisor. RxMxR shows the maximum retrusion calculated with the radiograph. GgMxR shows the maximum retrusion obtained with the George Gauge. 66% shows the position of the lower incisor with 66% of maximum protrusion. GgMxP shows the maximum protrusion obtained with the George Gauge. Values obtained with the George Gauge with 2 mm of vertical opening are shown on the figure; −6 mm for maximum retrusion; + 9 mm for maximum protrusion, + 4 for 66% of total advance.Back to article page
