Use of 3D-Printed Direct-to-Multiunit Abutment Cylinders for Efficient All-On-X Provisionalization: A Case Report
Abstract:
Digital dentistry has accelerated the precision and predictability of full-arch implant therapy, particularly through the use of stackable guide systems that coordinate bone reduction, implant placement, and prosthetic positioning. Immediate loading has simultaneously become a widely adopted strategy for edentulous rehabilitation. This case report describes a fully guided dual-arch reconstruction incorporating guided bone reduction, guided implant placement, and guided provisional prosthesis delivery using a four-part stackable guide system with novel 3D-printed direct-to-multiunit abutment (MUA) temporary cylinders. This approach increases material bulk around screw-access channels, eliminates on-site conversion procedures, and enables direct-to-MUA prosthesis delivery without same-day printing.
