Is ADDM graft practical? A comparative study to evaluate ADDM graft in third molar surgery.

Background: It has been outlined that LTM (Lower third molar) extracted from patients in which grinding, cleaning, sterilization & demineralization prove to be highly effective as graft material for filling the alveolar socket of the very same patient. These investigations aim to assess the efficiency of ADDM (Autogenous Demineralized Dentin Matrix) graft in third molar extraction sockets.

Purpose: To check the effectiveness of ADDM as graft material in extraction socket by evaluating pain, swelling, trismus, PD (Probing Depth) and bone density.

Study Design, Setting, Sample: A prospective, randomized control trial was conducted at our institute. The patients were haphazardly, non-blindly alienated into two groups. Group A (45 patients) on the test side after LTM impaction surgery will receive ADDM graft material with bio-collagen membrane and Group B (45 patients) on the control side underwent LTM removal, with the alveolus left to heal conventionally by forming a blood clot.

Results: Swelling showed significant difference between CG (Control Group) and TG (Test Group), the intergroup comparison of change in the swelling scores at seventh post-operative day (from pre-op level) was significantly higher in the TG (117.35) as compared to the CGs (115.92) (p = 0.001). A statistically significant difference in probing depth was also noted between the two groups, CG 4.46 ± 1.252 & TG 2.52 ± 0.641 in the post-operative examination at three months. In our study radiographical evaluation revealed progressive increase in bone density in TG (135.81 ± 8.73) when compared to CG (121.59 ± 13.83) over a period of three months. Pain and trismus evaluation did not reveal any significant difference between TG & CG.

Conclusion: The clinical results of the ADDM graft procedure demonstrate satisfactory outcomes in extraction sockets. The findings of this study highlight the importance of preservation methods in maintaining the periodontal pocket depth distal to the second molar and the remaining alveolar ridge following extraction.
