ABSTRACT
Objective@#To research the clinical effect of platelet rich plasma combined with Bio-oss artificial bone meal in repairing bone defects around implants.@*Methods@#From January 2015 to January 2017, 70 cases who completed the implant repair in Lishui People's Hospital, and later confirmed the defects around the implant were selected in the research.They were equally divided into observation group and control group according to admission, with 35 cases in each group.The control group was treated with Bio-oss artificial bone powder.The observation group was treated with platelet rich plasma combined with Bio-oss artificial bone powder.The clinical effects of the two groups were compared and analyzed.@*Results@#Before treatment, the probe depth (PD), clinical attachment loss (CAL), plaque index (PI), gingival sulcus hemorrhage index (SBI) of the observation group and the control group were (7.18±1.31)mm, (5.68±0.87)mm, (1.23±0.31), (2.48±0.34) and (7.22±1.28)mm, (5.74±0.83)mm, (1.27±0.33), (2.53±0.36), respectively, which were significantly higher than those after treatment (all P<0.05). Before treatment, the bone mineral density (BMD) levels of the two groups were (35.48±4.58)g/cm3 and (35.74±4.61)g/cm3, respectively, which were significantly lower than those after treatment (all P<0.05). The levels of PD, CAL, PI and SBI in the observation group at 3 months and 6 months after treatment were (4.48±1.01)mm, (4.27±0.53)mm, (0.68±0.21), (1.12±0.13) and (3.43±0.76)mm, (3.58±0.54)mm, (0.38±0.07), (0.41±0.08), respectively, which were significantly lower than those in the control group [(5.19±0.83)mm, (4.83±0.71)mm, (0.89±0.27), (1.46±0.21) and (4.14±0.98)mm, (4.21±0.62)mm, (0.49±0.11), (0.63±0.13)], the differences were statistically significant (t=3.213, 3.739, 3.632, 8.144 and 3.387, 4.533, 4.991, 8.526, P=0.002, 0.000, 0.000, 0.000, 0.001, 0.000, 0.000, 0.000, 0.000, 0.000). The levels of TA anterior temporalis muscle EMG and MA masseter muscle EMG in the two groups at 6 months after treatment were (76.81±15.17)mV, (67.56±14.43)mV, (74.24±13.28)mV, (68.27±13.03)mV, (66.44±13.28)mV, (58.76±13.07)mV, (65.58±11.55)mV, (59.04±10.76)mV, respectively, which were significantly higher than those before treatment [(46.48±11.15) mV, (38.19±13.04) mV, (54.83±12.57) mV, (56.48±13.13) mV and (45.71±10.98) mV, (38.23±13.11)mV, (55.14±12.69) mV, (56.61±13.08) mV] (all P<0.05). After treatment, the ICP-HB, ICMAP-MC, TA, EMG levels in the observation group were significantly higher than those in the control group, the differences were statistically significant (t=3.042, 2.674, 2.911, 2.994, P=0.003, 0.009, 0.004 and 0.003).@*Conclusion@#The effect of rich plate plasma combined with Bio-oss artificial bone powder on the repair of bone defect around the implant is significant.The platelet rich plasma can speed up and improve the repair speed and repair quality of bone defect around the implant, so that the therapeutic effect of implant repair can be maintained for a long time.
