Abstract

For patients with mild protrusion, implant anchorage in the zygomatic alveolar ridge area can retract the entire upper arch, providing a choice of non subtractive treatment. Therefore, the implantation of implant nails in the zygomatic ridge area has become a common clinical treatment. In this paper, the relationship between micro implant placement in the zygomatic ridge area and the location of the maxillary sinus floor was studied, in order to provide a reference for the clinical safety of implant placement in the zygomatic ridge. The width of the zygomatic ridge in the root of the first permanent molar was measured and analyzed by cone beam CT (CBCT) At the same time, the root length of the mesiobuccal root of the first permanent molar was measured to determine the location of the implant. The results showed that the width of the zygomatic alveolar ridge in the low sinus group was significantly smaller than that in the high sinus group, and the position of the bottom of the maxillary sinus determined the width of the zygomatic alveolar ridge In order to ensure the safety of apical tissue, it should be implanted more than 1-2 mm above the apical The implant site of male patients was about 14 mm above the enamel cementum boundary, while that of female patients was about 13 mm.
