Background:

Defining successful dental implant outcomes involves function, esthetics, phonetics, stability, and minimal complications.
Mandibular subperiosteal implants represent a historical approach to treating severe edentulism.

Observation:

A case report documents a mandibular subperiosteal implant with an unprecedented 56-year follow-up.
The patient achieved satisfactory function, esthetics, and phonetics throughout the follow-up period.

Findings:

Long-term success was attributed to meticulous patient selection, adherence to anatomical principles, implant/superstructure design, surgical skill, restorative expertise, patient hygiene, and regular follow-up.
This case highlights the critical role of interdisciplinary collaboration between surgeons, restorative dentists, and lab technicians, alongside sustained patient compliance.

Implications:

This case establishes a new benchmark for the longest-documented success in any dental implant treatment.
It underscores the potential for long-term stability and functional restoration with well-executed subperiosteal implants when combined with comprehensive patient management.
