Purpose: This retrospective study aimed to evaluate clinical and radiographic changes in the interproximal area between single-unit implant-supported restorations and adjacent natural teeth, and to assess their relationship with periodontal and peri-implant tissue health. Materials and Methods: A total of 22 single-unit implants placed in 18 patients (mean age 52.38 +/- 8.78 years) were followed for a mean period of 18.5 +/- 3.2 months (range: 3-24 months). During recall appointments, periodontal and peri-implant clinical parameters, radiographic findings, adjacent tooth vitality, opposing dentition status, and patient-reported food impaction were comprehensively recorded. Results: Interproximal contact loss (ICL) was detected in 68.2% of restorations, with mesial (36.4%) and distal (40.9%) contact loss observed. Additionally, contact loss affected both surfaces in 9.1% of cases. Among the 15 ICL implants, 9 (60.0%) were associated with patient-reported food impaction. ICL prevalence was notably higher in females (86.7%) compared to males (28.6%). Peri-implant mucositis was diagnosed in 53.3% of implants exhibiting contact loss, whereas no peri-implantitis was detected. Conclusion: ICL between implant-supported restorations and adjacent natural teeth is a frequent finding often associated with food impaction and peri-implant mucosal inflammation. Therefore, regular clinical and radiographic evaluation of interproximal contacts is essential for maintaining peri-implant tissue health and ensuring long-term restorative success.
