All-on-X Stackable Guides for Maxillary Terminal Dentition

All-on-X (Full-arch Implant-supported Rehabilitation) Stackable Surgical Guides for Maxillary Terminal Dentition: a 2-year Retrospective Analysis

Sponsor

Menoufia University

Enrollment

40 participants

Start Date

Jan 1, 2024

Study Type

OBSERVATIONAL

Conditions

Bone Loss

Summary

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.

Interventions

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

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.
