Oral and radiographic examination revealed moderate generalized bone loss except for #22 which showed grade III mobility (Figures 1(a) and 1(b)). Extraction of #22 was performed atraumatically under local anaesthesia (Figure 1(c)) and the socket was curetted thoroughly. The blood was centrifuged at 2700 rpm for 12 minutes, following which PRF obtained was placed in the extraction socket (Figure 1(d)) and stabilized using figure-of-eight suture using 5-0 polyamide (Ethicon). The natural crown was sectioned from the root using diamond disc to achieve modified ridge-lap shape (Figure 1(e)). As the patient desired to undergo implant therapy, CBCT was advised (Figure 1(i)).

She was diagnosed with generalized chronic periodontitis with grade III mobility of #12 (Figure 2(a)) which was unsalvageable. Extraction of #12 was performed atraumatically (Figure 2(b)). PRF was prepared as described above and mixed with beta-TCP (Virchow Co.) graft material to form a sticky mixture (Figure 2(c)) which was thereafter placed in the extraction site to facilitate socket preservation (Figure 2(d)). The natural crown was used as a pontic in a similar fashion, as has been discussed above (Figures 2(e)-2(f)).

After extraction of #42 (Figure 3(a)), the extraction socket was preserved using PRF and the natural crown was used as pontic (Figure 3(b)).
