Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Primary Objectives of the present study are :

* To Evaluate the effect of platelet rich fibrin matrix (PRFM) and peripheral blood mesenchymal stem cells (PBMSCs) on implant stability.
* To Compare the effect of platelet rich fibrin matrix (PRFM) alone to peripheral blood mesenchymal stem cells (PBMSCs) embedded in platelet rich fibrin matrix (PRFM) on implant stability.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The addition of molecules or growth factors to the implant surface is an approach to enhance bone to implant contact (BIC).1 Platelet rich fibrin matrix (PRFM) is an autologous concentrated platelet-rich thrombin free fibrin matrix, prepared by two step centrifugation of blood. Platelets isolated, remain intact and retain their growth factor compliment. This allows a more effective, sustained release of growth factors to the wound site following PRFM application.2 During the second spin, a cross-linking of fibrin takes place, resulting in the formation of a dense fibrin matrix, within which a concentration of viable platelets can be found. Having an organized fibrin matrix at the start of healing accelerates the speed of vascular ingress into the wound compared to non-accelerated healing, which requires a longer time for fibrin formation and the development of vascularity. The earlier the vascularity is established, faster is the migration of the bone-forming cells at the wound site and initiation of bone formation. Therapeutic applications of platelet-rich products have led to improved bone regeneration and faster titanium implant osseointegration, which improve the stability and maintenance of dental implants by increasing BIC.1 Mesenchymal stem cells (MSCs) is a multipotent stromal cell with prominent regenerative functions. MSCs were first identified and isolated from bone marrow and then found in various tissues including umbilical cord, adipose tissue and peripheral blood. Among these sources peripheral blood MSCs draw increasing attention as they share similar biological characteristics with MSCs derived from bone marrow or adipose tissue. Bone marrow derived mesenchymal stem cells(BMMSCs) are multipotent cells capable of differentiating into osteoblasts, chondrocytes, adipocytes , fibroblasts, tenocytes, and myoblasts , which are considered as a cell source for various tissue repair and regenerating bone defects.3 The requirements of aspiration of bone marrow from the patient will cause pain and morbidity of the donor sites. It will be very convenient if peripheral blood mesenchymal stem cells (PBMSCs) could be harvested and expanded to enough numbers, with their osteogenic capacity maintained in a clinical permitted period.

The literature search does not show any human clinical trial conducted till date to assess the regenerative potential of this new modality i.e. PRFM and peripheral blood mesenchymal stem cells. This study therefore aims at the evaluation of PRFM and PBMSCs as regenerative materials for implant stability.
