Comparision of Clinical Efficacy of Immediate Implants With T-PRF and Bone-graft Versus PRF and Bone-graft

Overview

The normal architecture of the alveolar process is altered by periodontitis, which also causes the loss of alveolar bone surrounding the teeth. Untreated periodontitis may cause teeth to become mobile and leads to loss of teeth. In such cases, one of the treatment modalities is extraction of the tooth and placement of immediate implant which reduces the waiting period. And due to the resorption of alveolar ridge the bone graft will be used along with T-PRF and PRF. So this study aims at the placement of immediate implants along with T-PRF with bone graft and PRF with bone graft.

Dental implants have become more common treatment for replacing missing teeth and aim to improve chewing efficiency, physical health and esthetic. And their will be resorption of alveolar process due to periodontitis . In such compromised cases, to achieve bone augmentation around immediately placed implants a new modality of using platelet rich fibrin (PRF) along with graft material has gained considerable interest. Successful clinical results have been reported with L-PRF, but some physicians worry about a possible health hazard with glass-evacuated blood collection tubes with silica activators. O'Connell described the unavoidable silica contact. The silica particles in the tube, although dense enough to sediment with the red blood cells, are small enough for a fraction to remain colloidally suspended in the buffy coat, fibrin, and platelet-poor plasma layers therefore, these particles might reach the patient when the product is used for treatment. Recently use of titanium tubes in the preparation of PRF showed more polymerized fibrin formation with longer resorption in tissues as titanium seems to be more effective in activating platelets than silica and also eliminates the possible silica contamination. The use of T-PRF(Titanium PRF) along with xenograft creates a block graft with high concentrated growth factors, platelets and leucocytes which enhance development of bone and eliminates the possible silica contamination. Hence, the aim of the study is to compare the effectiveness of T-PRF with xenograft \[DMBM\] and PRF with xenograft \[DMBM\] around immediate implants.
