Abstract
Purpose
The extraction of a tooth is followed by hard and soft tissue changes which may compromise the implant placement. The aim of the present retrospective study was to compare the clinical and radiographical outcomes of different ridge preservation procedures based on the use of L-PRF.
Methods
The study population consisted of all patients operated on from 1 January 2017 to 1 January 2018 for alveolar ridge preservation on single posterior teeth using three clinical protocols based on L-PRF (L-PRF group), L-PRF mixed with a bone xenograft (L-PRF + B group ), and a bone xenograft alone (B group). Clinical and radiographical outcomes were recorded prior to the surgery and at six months after the procedure measuring the horizontal and vertical ridge resorption.
Results
In total, 45 patients were included in this study. All of the surgeries were successfully carried out and no intraoperative complications were recorded. L-PRF group had a significantly greater horizontal and vertical bone resorption while L-PRF+B group had less vertical and horizontal bone resorption as compared with B Group. Statistically significant differences in postoperative pain sensation and wound healing were observed with B group in particular showing higher values of pain and a delayed wound healing.
Conclusion
Within the limitations of this retrospective study, the use of a bone xenograft alone or L-PRF combined with a bone xenograft for performing alveolar ridge preservation procedures significantly limited bone resorption.
