Abstract
Objectives: This study was conducted to assess and compare the effect of autogenous bonegraft versus mineralized plasmatic matrix (MPM) and versus the Nano hydroxyapatite bone graftas bone regenerative materials during immediate implant placement.Material and Methods: A total of 14 patients with 18 implants have been included in thisstudy, patients were divided into 3 groups. Group I(control group) received autogenous bone graft.Group II (study group A) received Mineralized Plasmatic Matrix (MPM), and group III (studygroup B) received Nano hydroxyapatite as bone regenerative materials for immediate implantplacement. The treatment outcome was evaluated clinically and radiographically at 3 and 6 monthsof implant placement. Implants stability was measured using Osstell radiofrequency device at 3 and6 months postoperatively. Also bone density were measured radiographically at 2 weeks and at 3and 6 months postoperatively and statistically analysed.Results: Statistical analysis of bone density measurements between the three groups showedsignificant difference (P ≤ 0.05) between the control autogenous bone group and the two othergroups (MPM &Nano bone) at all time intervals. Comparison between the test groups revealednon-significant difference (P ≤ 0.05) between (MPM & Nano bone) at two weeks interval. Whileat three & six months postoperatively there was a significant difference (P ≤ 0.05 between the twogroups. Regarding implant stability comparison between the three groups , there was no statisticalsignificant difference between them (P ≤ 0.05) at three and six months post operatively.Conclusion: The autogenous bone graft remains the gold standard for grafting materials but theuse of MPM and Nano hydroxyapatite grafting materials can also give successful results regardingimplant stability and bone density.
