In long-span fixed partial denture restoration, especially when pier abutment is present, it functions as a fulcrum, causing more fixed dental prosthesis to debond, which eventually has an impact on the success of fixed partial dentures, so a non-rigid connector is indicated in that conditions. The non-rigid connector is classified into a dovetail, loop connector, split pontic, cross-pin and wing. The rotation and resilience between the prosthetic restoration and abutment teeth are made possible by the split pontic stress-releasing action, which serves as “safety valves” against connector leverage forces. Split pontics are anticipated to offer a design with a promise for prosthesis stability and retention with a recognised aesthetics.
