CAD/CAM Abutments versus Stock Abutments: An Update Review

With the evolution of CAD/CAM technology, custom titanium and/or zirconia abutments are increasingly being used, leading to several comparisons in literature, both mechanical and aesthetic, evaluate performance differences between these two types abutments. Therefore, aim this comprehensive review is present most recent data on latest stock abutment applications. The PICO model was used perform review, through a literature search PubMed (MEDLINE) Scopus electronic databases. allow individualization parameters with respect soft tissue, increased fracture toughness, predict failure mode, show no change toughness over time, reduce prosthetic steps, functional implant prosthesis score pain perceived by patients early stages. advantages associated use mainly concern risk corrosion, time spent, cost, fit, evaluated vitro, implant–abutment connection. Equal conditions regarding characteristics during dynamic cycles, screw loss, radiographic degree micromotion. Further randomized controlled clinical trials should be conducted reported date, following vitro studies about
