Detailed Description
Many studies have reported an approximately 50% reduction in alveolar bone both the horizontal and vertical directions over 12 months with more than two-thirds of the reduction occurring in the first three months after extraction. Alveolar ridge preservation is a procedure that attempts to reduce bone dimensional changes that naturally take place following tooth extraction. During the last decade, efforts have been made to confirm procedures that can prevent bone resorption after extraction. The use of bone grafts aim to promote bone healing and assist bone regeneration. Various types of materials are used for socket preservation, such as autogenous bone, allograft bone, xenograft materials, and alloplast materials.
Dentin contains several growth factors, including transforming growth factor beta (TGF-β), insulin-like growth factor-II (IGF-II) and bone morphogenetic protein-2 (BMP-2), which could be of pivotal importance during any healing event. Demineralization of dentin has been further proposed to expose its collagen matrix, liberate 'fossilized' growth factors and thereby enhance its regenerative capacity.
It has been proven that autogenous demineralized dentin graft is effective at reducing dimensional losses of alveolar sockets after 6 months, with no adverse effects.
The efficacy of platelet rich fibrin (PRF) in promoting wound healing and tissue regeneration is at the center of a recent academic debate. The liquid fibrinogen has been shown to bind particulate bone grafts, which are then called "sticky bone". This binding improves the stabilization of the particles in the defect. It adds a potential biological effect, which could accelerate the soft tissue healing process and optimize the handling properties of the granules.
The purpose of this clinical trial is to assess the capacity and the clinical feasibility of the dentin graft processed with injectable platelet rich fibrin (I-PRF) to an adherent, tooth-derived conglomerate for socket preservation. Moreover, Platelet-rich fibrin incorporated with antibiotics showed long-term anti-bacterial effect against F. nucleatum and S. aureus.
Both autogenous demineralized dentin graft combined with injectable PRF (sticky demineralized tooth) and autogenous demineralized dentin graft (ADDG) alone, with or without collagen membrane, have been utilized for alveolar ridge preservation or augmentation but the superiority of one form over the other is not yet clear.

EXPERIMENTAL: Alveolar ridge preservation using demineralized dentin combined with I-PRF + metronidazole
Atraumatic extraction of non-restorable teeth, then the extracted tooth will be prepared and demineralized using hydrochloric acid (HCL) acid as particulate demineralized dentin graft and processed with injectable platelet rich fibrin.
The injectable PRF will be mixed with 5mg/ml metronidazole first then added to the particulate demineralized dentin graft then inserted in the extraction socket and covered then suturing

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Alveolar ridge bucco-lingual width change in mm
Time Frame: 6 months
|
Alveolar bone linear width will be measured at baseline and after 6 months using cone beam computed tomography (CBCT) scans.
The change in bone width will be calculated as the subtraction of final width from baseline width and will be measured in millimetres

6 months
|
Histological assessment
Time Frame: 6 months
|
Bone samples from control and experimental sites will be taken during implant placement using a trephine bur of a size smaller than the implant.
Samples will be examined for new bone formation (Yes/no).
