Full-Arch Guide Concepts in Static Computer-assisted Implant Surgery (sCAIS): Applications in Partial Edentulism and Full-Arch Rehabilitation

Abstract

Static computer-assisted implant surgery (sCAIS) is a well-established digital approach that enables the prosthetically driven placement of dental implants using prefabricated surgical guides. In partially edentulous patients, guide stability is a critical determinant of accuracy and clinical safety. Full-arch-supported guides represent a specific design concept in which the surgical template is supported by multiple teeth and/or extended mucosal areas across the entire arch, with the aim of maximizing positional stability during surgery. This narrative review summarizes current knowledge on the indications, digital workflow, accuracy, advantages, limitations, and clinical management of full-arch-supported guides in sCAIS for partial edentulism as well as terminal dentition scenarios. Available evidence indicates that, when properly planned and executed, full-arch-supported guides provide accuracy comparable to conventional tooth-supported guides and allow predictable minimally invasive implant placement. Clear clinical recommendations and illustrative scenarios are provided to support evidence-based decision-making in daily practice.
