Arterial arcade of the maxillary sinus related to sinus bone graft in korean population ; A preliminary study using computed topographies

ABSTRACT

AIM: The aim of this study was to investigate the arterial arcade of maxillary sinus by determining the distance between the alveolar crest and the inferior border of the vessels in Korean population. MATERIALS AND METHODS: 76 patients and 87 available sinuses were determined by CT scan (Implagraphy, Vatech, Seoul, Korea). The distance between alveolar crest and inferior border of the vessel was determined considering the tooth area of posterior maxilla. RESULTS: The lowest distance was observed on first molar area and the average distance is 16.9 mm. DISCUSSIONS it is important in sinus lift surgery that the vessels not to be damaged and that the anastomosis is situated in the lateral wall of maxillary sinus, which has to be exposed to gain access to the maxillary sinus. The knowledge of arterial arcade of maxillary sinus is important to perform the sinus floor elevation procedure effectively.
