Improved pantograph clutches fabricated intraorally

A technique that improves intraorally made autopolymerizing resin pantograph clutches has been presented. The resulting clutches are comfortable and stable. Even after removing and reinserting the clutches several times, retention is sufficient to support the weight of the pantograph. Mandibular clutches have sufficient retention for accurate hinge axis location. If necessary, the same clutches can easily be relined for tracings during and after treatment. Replacing the relining material will adapt the clutches to changes in tooth contour that may occur as a result of treatment.
