The influence of the palatal major conccector on the rigidity of a conical crown retained denture.
The influence of the major connector on the rigidity of a maxillary conical crown retained denture was evaluated in vivo. A duplicate maxillary conical crown prosthesis carrying 9 electrical resistance strain gauges was manufactured for one partially dentate male. Clinical loading experiments were performed with the original construction design, after partial and complete removal of the major connector. The results showed that the separation of the major connector caused a general increase in the deformation level, particularly in the anterior region. In conclusion, the palatal major connector was found to increase the rigidity of a maxillary conical crown retained denture.
