Aim: Designing and fabrication of a digital computer-aided design and computer-aided manufacturing (CAD-CAM) implant abutment repositioning jig (IARJ) by using additive manufacturing.
Background: The implant-supported fixed complete denture (ISFCD) is a predictable treatment option in the restoration of the edentulous arch situations. Advancements in CAD-CAM have improved the workflow efficiency in ISFCD fabrication.
Technique: An implant abutment repositioning jig is used to ensure easy and accurate placement of angled multiunit abutments (MUAs). This report describes a technique, a digital workflow, and fabrication of IARJ.
Conclusion: Use of digital technology in IARJ fabrication offers certain advantages such as an easy archiving STL file, fabrication for future maintenance or replacement of MUAs if needed.
