Orthodontic elastomeric chain as an alternative to dental floss for splinting implant impression copings for complete-arch implant impressions
The most significant step in fabricating an accurate implant prosthesis is to transfer the precise 3D intraoral location of the implants to the definitive cast.1 Various impression techniques have been described to achieve the necessary accuracy.2 The open tray impression3 has been widely used; however, translation and rotation of these transfer impression copings may occur when the copings are detached from the implant fixture and during placement of the implant analog.4 Lee et al5 concluded in their systematic review that splinting transfer impression copings produced an accurate definitive cast and prevented micromovement of the impression copings.
