It needs operation to repair when perforation diameter more than 5mm or with maxillary sinus inflammation. The traditional maxillary sinus puncture repair methods mainly include the surgical methods and non-surgical methods. Each method has its own advantages and disadvantages. In recent years, with the popularity and the development of biomedical and oral implant technology, the absorbable material and the Bio-oss-Bio-Gide Sandwich technique are occured.
