Summary

24 patients had a treatment plan for extraction of non restorable single rooted maxillary tooth and will be subjected to one of three groups after tooth extraction Group (I): including 8 patients, preservation of extraction sockets will be done with combination of collagen sponge and xenograft will be placed on top of the collagen sponge to fill the coronal part of the socket, till crestal bone level and socket sealing will be done with a new layer of collagen sponge(superficial collagen layer) and criss-cross suture to stabilize the graft in place. Group (II): including 8 patients, preservation of extraction sockets will be done with collagen sponge alone and criss-cross suture. Group (III): control group, including 8 patients, preservation of extraction sockets will be done with atraumatic extraction and left for spontaneous healing with criss-cross suture.

Detailed description

\- Surgical Phase: * Local infiltration anesthesia will be first administered to all patients in this study. * Teeth will be extracted, using a flapless approach a traumatically as much as possible. * Atraumatic extraction will start with dissection of periodontal ligaments in crestal part using 15C blades mounted over a round-handed blade to facilitate rotation without lacerating the soft tissue * Then teeth will be luxated using micro-elevators and the final delivery movement will be done using forceps. * Sockets will be thoroughly debrided using a curette, especially in case with periapical lesions, to ensure complete removal of granulation tissue. * Assessment of sockets walls integrity will be done visually and using a UNC-15 periodontal probe. All patients will be allocated into one of the three study groups. Group (I): including 8 patients, preservation of extraction sockets will be done with combination of collagen sponge and xenograft will be placed on top of the collagen sponge to fill the coronal part of the socket, till crestal bone level and socket sealing will be done with a new layer of collagen sponge(superficial collagen layer) and criss-cross suture to stabilize the graft in place. Group (II): including 8 patients, preservation of extraction sockets will be done with collagen sponge and criss-cross suture. Group (III): control group, including 8 patients, preservation of extraction sockets will be done with atraumatic extraction and left for spontaneous healing with criss-cross suture.
