INTRODUCTION OF CONNECTORS IN FPD (Fixed Partial Denture) 🎯 KEY POINTS: 🔸Connectors unite the retainers and pontics in an FPD. 🔸Types include rigid and non-rigid connectors. 🔸Rigid connectors provide maximum strength and rigidity. 🔸Non-rigid connectors allow for some flexibility to accommodate stress.
RETAINERS IN FPD 🎯 KEY POINTS: 🔸Retainers are the part of an FPD that attaches to the abutment teeth. 🔸They provide retention and support for the pontic. 🔸Types include full crowns, partial veneer crowns, and resin-bonded retainers. 🔸Full crowns cover the entire clinical crown of the abutment tooth. 🔸Partial veneer crowns cover only a portion […]
