Comparison of 3D-Printed Single Crown Outcomes Among Different Computer-Aided Design Software Programs.

Purpose: Low-cost resin 3D printers have been used to produce affordable interim single crowns in public and private dental practices. The purpose of this study was to assess the impact of different computer-aided design (CAD) software programs on 3D trueness, microscopic marginal and internal gaps, time to design, and interproximal contacts of low-cost 3D-printed single crowns.

Materials And Methods: This in vitro study was performed on a total of 90 standardized resin-prepared teeth adapted to a dental manikin.

Does Clinical Experience Affect Chairside Digital Waxing of Single Crowns More Than Software Training?

Purpose: To compare the accuracy of dentists with different levels of expertise in computer-aided design (CAD) and prosthodontics to digitally design single crowns.

Material And Methods: This in vitro study was conducted on 12 prepared teeth in 2 reference dental study models. The models were scanned using an intraoral scanner.

Computer-aided design expertise affects digital wax patterns of CAD/CAM laminate veneers more than single crowns.

Aim: There is controversy in the literature regarding clinical outcomes of CAD/CAM laminate veneers. The aim of the present study was to assess the impact of different levels of CAD expertise and different software programs on the reliability and reproducibility of digital wax patterns of laminate veneers and single crowns.

Materials And Methods: The present preliminary in vitro study was performed on 10 prepared maxillary central incisors available in dental study models.

Digital workflow to produce esthetic space maintainers for growing patients.

Digital workflows have been used to enhance the predictability of oral rehabilitations. However, techniques to digitally design and manufacture esthetic space maintainers by following a prosthetically driven treatment plan for young patients are lacking. This technique report describes a full digital workflow to produce computer-aided design and computer-aided manufacturing (CAD-CAM) esthetic space maintainers by using intraoral scans, a dental CAD software program, and a milling machine.

Influence of receiver bandwidth on MRI artifacts caused by orthodontic brackets composed of different alloys.

Purpose: The aim of this study was to assess the role of bandwidth on the area of magnetic resonance imaging (MRI) artifacts caused by orthodontic appliances composed of different alloys, using different pulse sequences in 1.5 T and 3.0 T magnetic fields.
