Abstract

PURPOSE: Surgical intervention into the maxillary posterior area can lead to inadvertent communication with the maxillary sinus. Spontaneous healing of 1 to 2 mm openings can occur. However, in patients with larger oro-antral communications and those with a history of sinus disease, surgical closure is often indicated. MATERIALS AND METHODS: In this case, a modified free gingival graft technique was used. The oro-antral sinus track after extraction was about 2x4 mm. But the patient had a history of Caldwell-Luc operation. Immediately after extraction, a modified free gingival graft was used for the closure of oro-antral sinus track. RESULT: A modified free gingival graft technique was successfully used for the closure of oro-antral sinus track. With this technique, esthetic results including similar colors, textures were achieved. CONCLUSION: It is thought that this technique is very useful in the closure of oro-antral sinus track.
