Parameters to Improve the Accuracy of Intraoral Scanners for Fabricating Tooth-Supported Restorations.

Objectives: To review the factors that impact the accuracy of intraoral scanners (IOSs) when fabricating tooth-supported restorations.

Overview: Factors can have a different impact on IOS accuracy depending on the scanning purpose. If the goal is to fabricate tooth-supported restorations, it is essential to review the following operator-related factors: IOS technology and system, scan extension and starting quadrant, scanning pattern, scanning distance, and rescanning methods.

Effect of Hydrogen Peroxide-Based Bleaching Agents on the Color Dimensions and Surface Roughness of Different Milled Restorative Dental Materials.

Purpose: To compare the color dimensions, color discrepancies (ΔE00), and surface roughness of milled materials before and after application of a bleaching agent.

Materials And Methods: A total of 10 extracted molars were obtained. Each tooth was cut in transverse sections to create disks (3-mm thick, 10-mm diameter; control group).

Classification of Complete-Arch Implant Scanning Techniques Recorded by Using Intraoral Scanners.

Objectives: To classify the complete-arch implant scanning techniques recorded by using intraoral scanners (IOSs).

Overview: Different implant scanning techniques have been described for recording complete-arch implant scans by using IOSs. However, dental literature lacks on a classification of these implant scanning techniques.

Digital workflow for the fabrication of custom-fit additively manufactured sports mouthguards with balanced occlusion using an optical jaw tracking system: A dental technique.

Custom sports mouthguards are used in various sports to protect teeth, temporomandibular joints, and soft tissues from impact forces. The present article demonstrates a digital workflow to fabricate a 3-dimensionally (3D) printed individualized sports mouthguard. An optical jaw tracking system is used to record a repeatable reference position, and mandibular excursive movements to achieve a completely balanced occlusion.
