PURPOSE: To investigate the anatomy of human maxillary sinus for providing some basic anatomical parameters related to sinus floor elevation and implant insertion.
METHODS: A total of 40 cone-beam CT (CBCT) adults were selected and analyzed. The length (internal wall) and width of the maxillary sinus were measured, and the incidence and distribution of septa were investigated by use of three-dimensional reconstruction technique of CBCT. SPSS 11.0 software package was used for statistical analysis.
RESULTS: The mean length (internal wall) and width of the maxillary sinus were (30.1±3.9) mm and (21.4±5.0) mm, respectively. There was no significant difference either in length or in width of maxillary sinus between males and females, or between right side and left side (P>0.05). Moreover, the incidence of sinus segments with septa was 53.8%(43/80).
CONCLUSIONS: Based on this study, the use of CBCT is advantageous and mandatory to avoid or reduce the incidence of surgical complications of maxillary sinus elevation.
