Objective: This retrospective clinical study aimed to investigate the long-term clinical success of dental implants restored with splinted or non-splinted posterior prostheses with different retention systems. Materials and Methods: Fifty patients who had undergone dental implant surgery and prosthesis treatment and had a follow-up period of at least 2 years were included in this study. Marginal bone loss was measured from the surrounding bone levels on the mesial and distal surfaces of the implants using a millimetre ruler on panoramic radiographs. The plaque index (PI), gingival index (GI) and bleeding on probing (BOP) were also measured. The Mann-Whitney U test and ANOVA test were used for statistical analysis. Results: The mean values of mesial and distal bone loss were 0.72±0.81 and 0.62±0.58, respectively. The correlation coefficient between mesial and distal bone loss was 0.431; thus, a significant difference was found (p<0.05). A significant relationship was found between the GI (p=0.004) and PI (p=0.000) of dental implants with different retention types. No significant relationship was observed between BOP and retention type (p>0.05). Conclusion:Clinically, given the long-term maintenance of soft and hard tissue health, successful results can be achieved with a two-member fixed prosthetic rehabilitation plan on two implants. Amaç: Bu retrospektif klinik çalışma, posterior bölgedeki farklı retansiyon sistemlerine sahip splintli veya tek başına planlanan protetik tedavinin dental implantların uzun vadeli klinik başarısına etkisini değerlendirmektedir. Gereç ve Yöntemler: Çalışmaya, dental implant cerrahisi ve sonrasında protetik tedavi uygulanan ve en az iki yıllık takip süresi olan 50 hasta dahil edildi.
