Full-Mouth Rehabilitation Using Combined Multiunit Abutment and Screw-Retained T-Base Abutment System: A Case Report with 24-Month Follow-up

The application of a multiunit abutment system in combination with a screw-retained T-base abutment for the all-in-six restoration of dental arches is considered a successful treatment for the maxillary and mandibular arches with implant-supported fixed prostheses.

This case report presents the successful use of a multiunit abutment system combined with a screw-retained T-base abutment to support all-in-six implant-supported fixed prostheses in maxillary arches. Meticulous treatment planning and execution resulted in predictable and favourable outcomes after implant-supported fixed prostheses were applied to a patient exhibiting a partially maxillary arch with mobile grade III bilateral canines.

The treatment protocol, prosthetic components, and clinical and radiographic outcomes after the final restoration were excellent after 24 months.
