Evaluation with a Coordinate-Measuring Machine of Dimensional Accuracy of the Abutment Duplication Technique in Cement- Retained Implant Restoration.

The article discusses the results of a study which evaluated the effectiveness and accuracy of a proposed duplication technique in terms of one- and three-dimensional discrepancies between an original abutment and polyurethane duplicates obtained through a conventional workflow in single-implant rehabilitation. Topics covered include master cast with the Giroform System, abutment duplication and the influence of duplication on crown marginal and internal adaptation.
