Accuracy of single crowns fabricated from ultrasound digital impressions

The development of computer-aided design and computer-aided manufacturing (CAD/CAM) technology applied to dentistry has allowed the use of more appropriate materials, with improved mechanical and aesthetic properties, to achieve standardized and accurate restorations with reduced cost in less time [1 –3]. The restoration fit is considered of pivotal importance for long-term clinical success of fixed dental prosthesis, considering that the body of clinical evidence has indicated marginal gaps as being a major problem leading to secondary caries, which compromises the integrity of abutment teeth and reduces the longevity of dental prostheses [4,5].
