We have experienced a lot of hemorrhage by injury of the superior posterior alveolar artery during extraction of the upper third molar. we tried hemostasis and the first attempt was unsuccesful. A gauze tampon was used, but it pushed out the sinus mucosa through the large bone defect. Our second attempt was succesful in attaining hemostasis of the superior posterior alveolar arterial hemorrhage. The method used was selective arterial embolization by angiography. We used the zeruform powder and the microcoil as the embolizing materials. It has made significant contributions to the management of patients with superior posterior alveolar arterial bleeding.
