This is an appliance that was developed at our lab to close diastemas. It gathers the centrals and laterals toward the midline. Permanent retention is accomplished by direct cosmetic bonding to close the residual space distal to the laterals after the space is closed. We use a traction screw but you can use a modified acrylic expansion screw if you modify it (too much work IMO) They also make a screw I show in the last picture to close diastemas but I could not find a pic of it in an appliance.
