The first requirement of a major connector is rigidity.Â This allows stresses that are applied to the partial denture to be distributed effectively over the entire supporting area, including the teeth, underlying, bone and soft tissue. Other components of a partial prosthesis can only be effective if the major connector is rigid. Flexibility allows forces to be concentrated on individual teeth or edentulous ridges causing damage to those areas. Continue reading
