Comparison of the efficacy of tricalcium phosphate and mineralized plasmatic matrix graft for the bone defect in the distal second molar tooth after surgery of the lower impacted third molar tooth

Abstract

Aim: After the extraction of mandibular horizontal and mesioangular teeth, a defect occurs in the distal part of the second molar. In this study, the effect of MPM on these defects was evaluated. Materials and methods: 36 patients randomly divided into 3 groups. The first group included MPM and PRF. The second group included B-tcp and PRF. In the 3rd group, the extraction socket was left empty. At preoperative and postoperative 6th months, periodontal pocket depth, gingival index and plaque index, and the distance between the enamel junction and crestal bone at the distal of the 2nd molar were measured by CBCT. 8 patients were removed for various reasons. 28 patients were evaluated. Results: Preoperative and postoperative periodontal pocket depths at the sixth month were 7.67 ± 1.58 mm and 4.67 ± 1.23 mm in the MPM group (p<0.001); 6.60±1.96 mm and 4.70±1.34 mm in the β-TCP group (p<0.001); 6.78±1.48 mm and 5.56±1.01 mm in the control group (p<0.023). Bone defects preoperatively and at six months postoperatively were 7.97 ± 1.04 mm and 3.59 ± 0.66 mm in the MPM group (p<0,001); 6.23 ± 1.37 mm and 2.90 ± 1.04 mm in the β-TCP group (p<0.001); 6.92±0.82 mm and 4.30±0.68 mm in the control group (p<0.001). Conclusion: MPM is an effective graft material to restore the periodontal health of the distal part of the second molar after impacted lower third molar surgery
