Cone-beam CT study of bone septa during maxillary sinus lift among Changzhou population

Abstract

Abstract: PURPOSE: To observe the incidence, location, morphological characteristics of sinus septa among Changzhou population, and to investigate the relationship between maxillary posterior teeth loss and bony septum, and the guiding significance for sinus lift. METHODS： One hundred and twenty-four subjects were selected, the preoperative cone-beam CT (CBCT) data was analyzed by NNT software, which provided a three-dimensional measurement of the maxillary sinus septa. SPSS 13.0 software package was used for statistical analysis. RESULTS: 33.87%（42/124）subjects had sinus septa, 27.42%（68/248）sinus had septa. 66.18% (45/68) of the septa were located in the middle region, 22.06% （15/68）in the posterior region, 11.76%（8/68） in the anterior region. The occurrence of sinus septa had no relation with gender, age and loss of teeth. CONCLUSIONS: The sinus septa can be observed by CBCT for the position, pattern, to predict the difficulty of the surgery, and enhance the success rate.
