Evaluation of the marginal fit of lithium disilicate single crowns fabricated with the conventional (IPS e.max Press) and CAD/CAM (IPS e.max CAD) methods: a systematic review and meta-analysis.

Aim: The purpose of the present systematic review and meta-analysis was to evaluate the marginal adaptation of single-unit full-coverage lithium disilicate fixed dental restorations fabricated with the conventional heat-pressed technique and the digital CAD/CAM workflow.

Materials And Methods: The present study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Α study research was conducted in Medline via PubMed and Cochrane Library databases together with a hand search of studies published until June 2022.

Characteristics of intraoral scan bodies and their influence on impression accuracy: A systematic review.

Objective: The aim of this systematic review was to evaluate the influence of the characteristics of intraoral scan bodies (ISBs) on the accuracy of intraoral scanning.

Materials And Methods: An electronic search was conducted through PubMed (MEDLINE), Scopus and Cochrane Library, up to March 2023. The literature search intended to retrieve all relevant clinical and in vitro studies about the effect that the various properties of ISBs may have on the accuracy (trueness and precision) of intraoral scanning.
