Mechanical Guide Table

Putting it together Table flush to front Incisal guide pin with flat blade end parallel to straight line on table All settings initially set at zero Guide pin set at zero

Setting the mechanical guide table *Loosen the inner wider thinner nut on bottom to place guide table on articulator *Tighten inner nut to hold table in place *Do not turn the outer nut if possible. If taken off, the table will come apart. The thicker outer nut, when loosened will allow table to Tilt the table in the anterior-posterior direction.

Setting anterior-posterior tilt of table Place incisal edges of maxillary incisors edge-to-edge *Tilt table up until incisal guide pin touches table Tighten outer nut to lock table in this position *This protects the cast in protrusive movements

Setting lateral wings of guide table The lateral wings are moved by turning the screws attached to each side of the wings. Twist these screws to move the wings of the table. Screws have a lock screw on them.

Place the canines in edge-to edge relationship

Twist screw until table wing touches the incisal guide pin Teeth and incisal guide table should touch simultaneously

Move to the other side and repeat Canines edge-to-edge Twist screw and lift wing to touch pin

Verify all settings and articulation of casts in all excursive movements Teeth and incisal guide table should touch simultaneously
