A disadvantage of long span flexible major connective in a partial denture is
1) Excessive force on residual ridge and periodontal ligament of abutment teeth
2) Cannot be relined
3) Decreased stability of prosthesis
4) Excessive force on residual ridge only

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

Flexible partial dentures reduce the leverage effects on abutment teeth due to their inherent material properties.�However, a major disadvantage of long-span flexible major connectors is that their increased flexibility can lead to excessive forces being transmitted to the underlying residual ridge and the periodontal ligament of the abutment teeth, as the force is less distributed compared to a rigid connector.�This can accelerate residual ridge resorption and damage the abutment teeth.�
