Prospective study evaluates clinical outcomes of combined periodontal and orthodontic treatments in severely compromised teeth, suggesting effective long-term tooth preservation.
Key Points
Evaluate the 20-year clinical outcomes of periodontal regenerative and orthodontic treatment for severely compromised teeth.
Prospective study with 48 patients having Stage IV periodontitis and test teeth with probing depth ≥ 7 mm.
Treatment protocol included instrumentation, regenerative surgery using EMD, orthodontic treatment, and supportive care.
Clinical parameters recorded at baseline, 10-year, and 20-year follow-ups.
Tooth survival at 20 years was 89.1% (CI: 79.4-99.9%), with a complication-free probability of 86.3% (CI: 75.7-98.3%).
Full-mouth plaque scores decreased from 48.8% to 14.6% (p < 0.001), and bleeding scores from 55.5% to 10.2% (p < 0.001).
Mean probing depth decreased from 6.3 mm to 3.0 mm (p < 0.001), with 81.8% of cases achieving treatment success.
