Objectives: To assess prognostic factors for tooth loss after active periodontal therapy (APT) in patients with aggressive periodontitis (AgP) on tooth-level. Material and Methods: 84 patients with AgP were re-evaluated after a mean period of 10.5 years of Supportive Periodontal Therapy (SPT). 2154 teeth were entered into the model. The tooth-related factors: baseline bone loss, tooth location and type, furcation involvement (FI), regenerative therapy, and abutment status as well as time of follow-up and other patient-related factors were tested for their prognostic value on tooth level. Multilevel regression analysis was performed for statistical analysis to identify factors contributing to tooth loss. Results: During SPT 113 teeth (1.34 teeth per patient) were lost. Baseline bone loss, use as abutment tooth, tooth type, and maxillary location contributed significantly to tooth loss during SPT. Molars showed the highest risk for tooth loss after APT. Also, time of follow-up and the patient-related factor 'educational status' significantly accounted for tooth loss on tooth level. Conclusion: Baseline bone loss, abutment status, tooth location and type as well as time of follow-up and educational status were detected as prognostic factors for tooth loss during SPT in patients with AgP at tooth-level.
