The surgical procedure was performed as follows: first, the fractured premolar root at the recipient site was atraumatically extracted (Figure 5a, 5b) using piezosurgery, then, the socket was prepared by drilling for the premolar with longer root [Figure 5c].

RPM, 400 g for 10 min. Residual cells were scraped and removed, and the fibrin clot (figure 6a) was transferred to a PRF box and compressed (PRF-BOX MCT, Seoul, Korea). As such the PRF membrane was prepared [Figure 6b]. At this stage, the PRF membrane was applied to socket walls (Figure 6c) and the atraumatically extracted donor premolar tooth with intact PDL was immediately implanted in the site and secured with a simple suture.(Figure 7a, 7b) The tooth was splinted to adjacent teeth with ligature wire for 2 weeks.

Superimposition of the pretreatment and posttreatment lateral cephalogram tracings revealed that no noticeable skeletal change was obvious, there was slight maxillary molar tipping, proclination of maxillary incisors had occurred and there was no change in lower incisor inclination [Figure 10].

The serial periapical radiographs confirmed the absence of any pathological status: ankylosis, replacement resorption, and inflammation were ruled out and the lamina dura was intact around the root [Figure 13].
