On examination, Grade III mobility with a probing pocket depth of >10 mm and suppuration was observed in relation to the maxillary right central incisor [Figure 1a]. Orthopantomogram (OPG) revealed an extensive bone loss in relation to 11, suggesting a hopeless prognosis [Figure 1b]. The extraction socket was curetted and irrigated with antiseptic povidone-iodine to remove the granulation tissue [Figure 1c]. Five milliliter venous blood was collected from the antecubital fossa, platelet-rich fibrin (PRF) membrane was prepared using a centrifuge machine, and this membrane was placed in the extraction socket [Figure 1d].

The root portion of the tooth was reduced using airotor to the desired length [Figure 2a]. The NTP and abutment teeth were etched with 37% phosphoric acid for 30 s and washed off [Figure 2b]. Then, the bonding agent was applied to the tooth and splinted the NTP to the adjacent teeth using light-cured composite resin [Figure 2c].
