Impact of implant scan body material and angulation on the trueness and precision of digital implant impressions using four intraoral scanners–an in vitro study

BMC Oral Health
Background Intraoral scanners (IOS) offer advantages in implant dentistry, but accuracy depends on factors including implant scan body (ISB) material and implant angulation. Conflicting evidence exists on the performance of Titanium (Ti) versus PEEK ISBs,
