About this trial

This retrospective study will evaluate the clinical performance of maxillary All-on-X(full-arch implant-supported rehabilitation) implant rehabilitation using stackable guided surgery and immediate loading. Implant survival and peri-implant outcomes will be assessed over a 2-year follow-up, with regression analysis will be used to investigate the influence of surgical and prosthetic variables, including basal seating guide design.

Trial population

The study population consists of adult patients with terminal maxillary dentition who underwent rehabilitation with a maxillary All-on-6 implant-supported complete fixed dental prosthesis using a fully digital stackable guided surgery workflow and immediate loading protocol. Patients included had complete clinical and radiographic records available and were followed for a minimum of 2 years. Prosthetic designs were limited to FP-1 or FP-2 according to Misch classification. Patients with uncontrolled systemic conditions, previous head and neck radiotherapy, untreated infections, or requiring simultaneous bone grafting were excluded.

Treatments tested in this trial

  • Maxillary All-on-X implant rehabilitation using a fully digital stackable guided surgery workflow with immediate loading.

    Other intervention

    Patients underwent maxillary full-arch implant rehabilitation using an All-on-X concept performed with a fully digital stackable guided surgery workflow and an immediate loading protocol. Implant placement was planned prosthetically using three-dimensional imaging and digital planning software. Stackable surgical guides were used to facilitate guided bone reduction when indicated and fully guided implant placement. Six implants were placed in the maxillary arch under local anesthesia following a standardized surgical protocol. Implants achieving adequate primary stability were immediately restored with a screw-retained provisional fixed prosthesis supported by multi-unit abutments. Patients were followed according to a predefined clinical and radiographic protocol for outcome assessment.

Implant Survival Rate

Implant survival was defined as the presence of the implant in situ without removal for any reason, including biological or mechanical failure. Survival was assessed clinically and radiographically following implant placement and immediate loading.

Time frame
6 months after implant placement
