Three-dimensional (3D) printing in dental practice: Applications, areas of interest, and level of evidence.

Objectives: The aim of this review to overview three-dimensional (3D) printing technologies available for different dental disciplines, considering the applicability of such technologies and materials development.

Materials And Methods: Source Arksey and O'Malley's five stages framework using PubMed, EMBASE, and Scopus (Elsevier) databases managed this review. Papers focusing on 3D printing in dentistry and written in English were screened.

The trueness of scans using one intraoral scanner in different partially edentulous conditions.

Purpose: To investigate the trueness of intraoral scanning in 8 commonly seen partially edentulous conditions.

Materials And Methods: A maxillary dentoform was modified into the 8 commonly seen partially edentulous conditions. Each modification was scanned with a laboratory desktop scanner.

Effect of cementation, cement type and vent holes on fit of zirconia copings.

Objectives: To investigate the effect of cementation, cement type and vent-holes on the marginal and internal fit of Zirconia (Zr) Copings.

Materials And Methods: Extracted premolars (N = 100) were mounted in resin and prepared for Zr crowns. Samples were randomly divided into 5 groups (n = 20); A: No Cementation; B: Cementation with Glass-Ionomer (GI); C: GI + Vent-Holes; D: Cementation with Resin Cement (RC); E: RC + Vent-Holes.
