Abstract
Purpose: The current study researches the morphological aspect analysis of maxillary sinus septum by cone-beam computed tomography (CBCT). The acquired information about maxillary septum in this study is expected to be of great help for implant treatment, which is a major obstacle for maxillary sinus lift.
Materials and Methods: One hundred and fifty-one patients (77 men, 74 women) who visited Hallym University Kangdong Sacred Heart Hospital from January to July 2012 for impacted third molar were examined. The height and length of the septum and angle between the septum and maxillary sinus wall are studied by CBCT. The bottom maxillary sinus was divided into maxillary 1st premolar, 2nd premolar, 1st molar and 2nd molar area. The length, height and angle of the maxillary sinus were measured. p-values less than 0.05 were considered to be statistically significant.
Results: The prevalence of sinus septum was 26.5% (41/151). The mean length of the septum in males and females is 14.19 mm and 12.06 mm, respectively. The height of the septum is 11.25 mm in males and 7.15 mm in females. The angle with the sinus lateral wall is 87.31o and that with the basal wall is 95.24o. The anatomic location of the septa was distributed in the 2nd molar region (52.8%), 2nd premolar region (24.5%), 1st molar region (18.9%) and 1st and premolar region (3.8%). The loss of the remaining teeth as well as age were not related to the presence of sinus septa.
Conclusion: These results will be a good support for sinus elevation in implant installation. However, it is too difficult to accept the notion that age has a positive relationship with the number of septums. Thus, before surgery, taking CT images will provide more information regarding the sinus, including septums.
