Abstract: This prospective case report evaluated the 5-year clinical performance of a complete mandibular denture supported by an innovative T-OVER abutment system with PLUG T, anchored on a single midline implant. The system features a T-Connect paraboloid contour with double curvature and three pins in a tripod configuration. A 62-year-old edentulous female with severe mandibular atrophy, who declined bone grafting for personal and financial reasons, received a single 3.5 × 11 mm implant at the mandibular midline. After a 4-month healing period, the T-OVER system was activated, and complete dentures were fabricated with proper border molding and occlusal adjustments. The mandibular denture was semi-rigidly connected to the abutment via the PLUG T. Clinical and radiographic follow-ups were conducted four weeks post-loading and every six months thereafter. Over five years, the implant showed no bleeding on probing, stable probing depths (2–3 mm), and no marginal bone loss. The patient reported high satisfaction and an improved oral health-related quality of life. This case suggests that a single-implant mandibular overdenture using the T-OVER and PLUG T system may be a practical and, effective solution for edentulous patients unable to undergo complex or costly procedures.
