The Effect of Posterior Mandibular Ridge Augmentation Using Mineralized Plasmatic Matrix Versus Autogenous Bone Graft on Implant Body Stability: A Randomized Clinical Trial Comparative Study

In the study group:

• Full medical and dental history will be obtained from all the patients participating in this study (figure 2).
• Thorough clinical and radiographic examination for the ridge area to be treated will be done.
• Future implant site will be planned.
• Each patient will be asked to evaluate their overall satisfaction using a questionnaire before any intervention.
• Patients will receive 2 gm of amoxicillin 1 hour before surgery. They will be instructed to wash their mouths with a 0.12% chlorhexidine solution for 30 seconds immediately before surgery.
• The patient will receive inferior alveolar nerve block and long buccal nerve anesthesia using articane HCl 4% with 1:100,000 adrenaline local anesthetic solution using aspirating syringe and 27-gauge needle.
• After confirming the success of profound local anaesthesia, an incision will be made and flap will be reflected along the ridge of the previously planned intraoral donor site to completely expose bone.
• Autogenous bone graft will be obtained and will be grinded according to the dimensions of the present defect.
• MPM (Mineralized plasmatic matrix) will be prepared:

Tubes of 9 ml of venous blood will be taken from the patient and will be placed in a centrifuge at 2500 rpm / min for 5 min.

At the end of the centrifugation, the blood in the tube will be separated into two compartments one yellow and one red.

The yellow part will be withdrawn with a syringe to be mixed with the grinded autogenous bone previously obtained from intra oral site.
