Conclusion
SECONDARY, PLAQUE
According to this study, all three healing types applied in this study positively affected PPD and PPI values. This result may be related to the easier removal of plaque at the 2Ms’ distal aspects after extraction. On the other hand, in terms of the 2Ms’ ABLs, primary healing and membrane-based primary healing had superior results to secondary healing. In our opinion, especially when the patient’s bone level is insufficient, primary healing is advantageous and preferable. Additionally, the use of resorbable collagen membranes is a promising approach after the surgical extraction of impacted lower 3Ms, as it promotes bone regeneration and improves the periodontal status of the adjacent 2Ms.
