Accuracy of Guided Implant Surgery in 25 Edentulous Arches: A Laboratory Observational Study.

Purpose: To assess the accuracy of template-guided implant surgery for edentulous arches.

Materials And Methods: The stone master casts of 25 edentulous arches treated with either 4 or 6 implants with CBCT generated template-guided surgery were included in this observational cohort study. The stone casts generated from the surgical templates (group one) prior to implant placement were digitized into Standard Tesselation (STL) files with a reference scanner.

Digital Workflow: From Guided Surgery to Final Full-Arch Implant Prosthesis in Three Visits.

The purpose of this article is to report a digital workflow protocol for full-arch implant rehabilitation from guided surgery to final prosthesis in only three visits. This expedited protocol allows for implant placement with a surgical template generated from preoperative virtual planning and production of the CAD/CAM prosthodontic rehabilitation using a digital workflow. At the first visit, a guided implant placement protocol with the All-on-4 concept and immediate loading with the conversion prosthesis technique was done.
