Digital Workflow With a Triple Scanning Technique for Implant Rehabilitation in the Esthetic Zone.

This article describes the case of a partially edentulous patient who had undergone template-guided implant placement and was treated using a triple digital scanning protocol that allowed for CAD/CAM prosthodontic rehabilitation in a complete digital workflow. At the impression appointment, the provisional implant-supported screw-retained prosthesis was digitally scanned both intraorally (first scan) and, after removal, extraorally (second scan). After the second scan, scan bodies were placed intraorally and an implant-level digital impression was taken (third scan).

Thermal effects on pulp due to laser and handpiece usage.

Objective: The study was designed to compare changes in pulpal temperature during ablation of dental hard tissue while using two established erbium dental laser systems, a new CO2 laser system, and a conventional high-speed handpiece.

Methods: Eighty non-carious human extracted molars were separated into four sample groups of 20 teeth each. Three laser systems were used, respectively, to ablate the occlusal surface of the teeth in three of the groups for 60 seconds each.
