Post Extraction Changes Following Ridge Preservation Using Partially Demineralized Dentin Block Versus Xenograft

"The extracted tooth will be dried using air, then ground and partially demineralized with the Tooth Transformer device following the manufacturer's protocol. Dentin particles will be obtained with dimensions of 400-800 μm. The partially demineralized dentin will then be prepared by cutting the Leukocyte-Platelet Rich Fibrin (L-PRF) membranes into small pieces and mixing them with the dentin particles. Liquid fibrinogen will be added to the homogeneous mixture. Within a few minutes, the fibrinogen will convert into fibrin primarily from the activated blood platelets in the chopped L-PRF membranes. This process will effectively trap the biomaterial and the L-PRF pieces, forming the dentin block. After that, the sockets will be carefully packed with the dentin block and it will be covered with L-PRF membrane. To ensure stability and prevent displacement, the wounds will be secured using non-resorbable sutures."

In the control group using the Xenograft, the same extraction and socket debridement procedure will be performed. Following that, the extraction socket will be thoroughly filled with deproteinized bovine bone mineral, and a collagen membrane will be employed to cover the socket. The membrane will be shaped to extend 2-3 mm beyond the margins of the extraction socket and positioned just beneath the marginal mucosa. To ensure its stability, a cross-suture will be performed, securing the membrane in place.
