Abstract:
Alveolar ridge defects, especially Seibert Class III with combined horizontal and vertical loss, pose challenges in achieving optimal esthetics, function, and hygiene. The Andrews bridge, a hybrid fixed-removable prosthesis, offers an effective solution by combining the stability of a fixed component with the hygiene accessibility of a removable one. With advancements in digital dentistry, computer-aided design and manufacturing (CAD/CAM) now enable precise, fully digital fabrication of such prostheses. This case report presents a completely digital workflow for designing and fabricating an Andrews bridge, ensuring superior fit, esthetics, and functional harmony. The digital approach minimized laboratory errors, enhanced adaptation, and simplified clinical procedures. The final prosthesis provided improved facial support, phonetics, and hygiene maintenance. A fully digital Andrews bridge offers a predictable, efficient, and patient-centered solution for managing complex ridge defects where surgical or implant options are limited.
