Abstract:
Background: This systematic review aims to evaluate the effectiveness of computer-aided design/computer-aided manufacturing (CAD/CAM) versus conventional fabrication techniques in dental crown production, focusing on marginal fit, internal adaptation, fracture resistance, and clinical performance.
Methods: A search of PubMed Central, Google scholar and ScienceDirect was conducted for studies published between 2010 and 2023. We include original research articles comparing CAD/CAM and conventional methods for crown fabrication. Nine studies meeting eligibility criteria were included, with in vitro, in vivo, and clinical investigations. Data were extracted on study design, population characteristics, crown type, fabrication methods, and outcomes.
Results: Most included studies show superior marginal and internal fit, and enhanced fracture strength, in CAD/CAM-fabricated crowns compared to conventional crowns. Outcomes varied depending on material type, scanner and milling system used, and crown indication. Some studies found conventional methods give better adaptation in certain designs.
Conclusion: CAD/CAM technologies show good results in crown fabrication in multiple performance parameters. Despite technique sensitivity, digital methods are emerging as a reliable and better alternative to conventional techniques, which their broader clinical adoption.
