Abstract

 

Intraoral scanners (IOS) are widely used to take impressions for dental implants. This narrative review aims to deliver a thorough evaluation of the current evidence on using the direct digital workflow to fabricate implant-based prostheses in patients with partial or complete-arch edentulism in comparison to conventional impression (CI) techniques. 

 

Electronic research was performed on many in-vitro and in-vivo studies to compare the accuracy of digital impressions to conventional methods. This suggests that either technique can be employed to take impressions for dental implants. Regarding full-arch fixed dental prostheses (FPDs), CI techniques have demonstrated greater accuracy compared to digital methods. However, when considering time efficiency and patient satisfaction, IOS may be preferred in certain circumstances such as short-span implant sites.  

 

Since most identified studies were conducted in vitro, to investigate influential clinical factors including scanning accuracy and technical or biological complications, further in-vivo studies are required.
