•As much as possible teeth are separated from each other to

allow plastic to contact all sides of the tooth

•Pontics are small, thin and away from adjacent teeth

•Pontics disappear as adjacent teeth get close to it

•Starting movements are tipping or bodily movements to

separate teeth

•Virtual gable bends are placed when teeth surrounded by

plastic, and before full space closure

•Attachments designed to provide push surfaces
