Abstract
Oro antral fistula closure using sandwich technique
Highlights
The oroantral fistula is a pathological connection between the maxillary sinus and the oral cavity
Hanazawa Yet al (1952) [1] reported that Oro Antral Fistula commonly occur after third decade of life
24 Patients reporting to us between 2009 - 2011 for treatment of oro-antral fistulas were included in this study
Summary
The oroantral fistula is a pathological connection between the maxillary sinus and the oral cavity. Hanazawa Yet al (1952) [1] reported that Oro Antral Fistula commonly occur after third decade of life. It is more frequent in males and occurs mostly in the second and first molars followed by second premolar teeth. This paper describes a new surgical technique for Oro Antral Fistula closure using guided tissue regeneration membrane & bone substitute sandwich technique. Method: 24 patients with oro antral fistula were selected. Patients were followed up for swelling, infection, graft failure & healing, by clinical & radiographic methods. The reconstructed bony tissue regenerated from this technique is capable to receive an endosseous implant in the future
