Purpose: To evaluate the impact of different complete-arch digital scanning techniques and prosthesis types on the passive fit of computer-aided design and computer-aided manufacturing (CAD-CAM) verification devices.
Materials And Methods: Two different maxillary master casts with four multi-unit abutment (MUA) implant analogs (FP-1 and FP-3 prosthesis types) were used as the basis for fabricating verification devices through two impression techniques (OptiSplint and RevEX). Group 1 utilized digital scans of splinted scanbodies reinforced with a light-polymerizing acrylic resin and metal mesh on the FP-1 cast (OptiSplint technique), Group 2 employed the same impression technique as Group 1 on the FP-3 cast, Group 3 applied digital scans of reverse scanbodies connected to a passively fitting interim prosthesis on FP-1 cast (RevEX technique), and Group 4 used the same impression technique as Group 3 on FP-3 cast.
Purpose: To evaluate the impact of different complete-arch digital scanning techniques on the passive fit of computer-aided design and computer-aided manufacturing (CAD-CAM) verification devices.
Materials And Methods: A mandibular master cast with four multiunit abutment implant analogs was used as the basis for fabricating verification devices through three impression techniques. Group 1 employed a conventional open-tray impression technique using polyvinyl siloxane material, Group 2 utilized digital scans of splinted scanbodies reinforced with a light-polymerizing acrylic resin and metal mesh, and Group 3 applied digital scans of reverse scanbodies connected to a passively fitting interim prosthesis.
