Abstract
Objectives
To compare the effectiveness of Autologous Particulate Dentin (APD) with Demineralized Freeze-Dried Bone Allograft (DFDBA) in ridge preservation, using radiographic and clinical parameters.
Materials and Methods
Thirty subjects with the indication of mandibular posterior teeth extraction were randomly assigned to either a test or control group. After atraumatic extraction, ridge preservation was performed using APD mixed with i-PRF in the test group and DFDBA mixed with i-PRF in the control group. Both groups had sockets sealed with an A-PRF membrane. Clinical parameters (plaque index, gingival index, healing index) and radiographic parameters (vertical ridge height, horizontal ridge width) were assessed at baseline and 6 months using CBCT.
Results
The test group exhibited a lesser reduction in ridge dimensions compared to the DFDBA group (p < 0.001). Both groups showed a significant decrease in ridge dimensions from baseline to 6 months (p < 0.001). There was no statistical difference in clinical parameters (plaque index, gingival index, healing index) between the groups at 6 months (p > 0.001).
Conclusions
APD grafts resulted in significant improvements in radiographic parameters, specifically in vertical ridge height and horizontal ridge width, compared to the DFDBA group.
Clinical Relevance
Autologous particulate dentin is a promising, versatile substitute for regenerative procedures. While more research on its long-term efficacy and application is needed, current evidence suggests it could significantly improve patient care and outcomes.
