Intraoral scanners (IOS) have revolutionized implant dentistry, offering a quicker, more efficient, and patient-friendly alternative to traditional impression methods. Digital impressions using IOS technology are increasingly common, providing significant advantages over conventional techniques, such as reduced time, enhanced comfort, and preventing material distortion. However, accuracy depends on factors including ISB material and angulation. The study evaluated the combined effect of ISB material (PEEK vs. Titanium) and angulation (0° vs. 30°) on trueness and precision of digital impressions. A factorial design was used to assess these factors, and results showed that ISB configuration significantly influenced trueness (P < 0.001) and precision (P < 0.001). PEEK ISBs demonstrated higher trueness and precision than Titanium ISBs, with PEEK 30° showing the highest trueness and PEEK 0° the best precision. Angulation did not significantly affect trueness for Titanium ISBs. The study highlights that both ISB material and angulation are critical factors, with PEEK consistently outperforming Titanium. Clinicians should consider these factors when selecting materials and IOSs for optimal accuracy. The present study aimed to assess the impact of ISB material and angulation on digital impression accuracy, leading to significant findings on their combined effect.
