Objective:
Evaluation of the 10-year results after GTR-therapy of infrabony defects using two bioabsorbable barriers in a randomized-controlled clinical trial.
Material And Methods:
In 15 patients with periodontitis, 15 pairs of infrabony defects were treated. For each patient, one defect received a polydioxanon (test: T) and the other received a polylactide acetyltributyl citrate (control: C) barrier by random assignment. At baseline, 12 and 120 +/- 6 months after surgery, the clinical parameters and standardized radiographs were obtained.
Results:
Nine patients were available for the 120-month re-examinations. Twelve and 120 +/- 6 months after therapy statistically significant (p
Conclusions:
PAL-V gain achieved after GTR therapy in infrabony defects using both bioabsorbable barriers was stable after 10 years in 15 of 22 defects (68%).
