Evaluation of efficacy of placing delayed dental implant following “Ice-cream Cone Technique” of socket preservation using Autologous Heat Compressed Platelet-rich-fibrin (PRF) membrane with Bone Allograft compared to Collagen Membrane with Bone Allograft: A Randomized Controlled Study.

Participants who satisfy the eligibility criteria will be alloted after randomisation into three groups. the first group will undergo ice cream cone technique of socket preservation with autologous heat compressed prf membrane and DFDBA bone graft. the second group will be treated with ice cream cone technique of socket preservation with resorbable collagen membrane  and dfdba bone graft. third group will be followed up to observe the natural healing of the extraction socket , the primary outcome would be to asses the change in the bucco-lingual dimension of the extraction socket following interventions in all three groups along with the assesment of feasibility of placing dental implant post socket preservation without the need for ridge augmentation procedure. clinical measurment of ridge dimensions will be made with intraoral scanner , radiographic measurement will be made with cbct. histological anlyasis of preserved socket bone and patient centered outcome in all thee groups will be assesed as secondary outcome. comparision of results will be made between all three groups.

autologous heat compressed prf membrane has been used as barrier membrane because of its increased time of biodegradation and if the results of this study prove that autologous heat compressed membrane is as efficacious as resorbable  collagen membrane in socket preservation then it will be cost effective for patient undergoing socket preservation following extraction as the prf membrane derived from patient own blood.
