Abstract

Objective: The purpose of this study was to evaluate the effect of malocclusion in skeletal class I, II, III on maxillary sinus dimensions. Materials and Methods: 30 cone-beam computed tomography (CBCT) images of 30 patients were analyzed. MSH (maxillary sinus height) and MSL (maxillary sinus length) were measured using the MIMICS 19.0 software (Materialise HQ Technologielaan, Leuven, Belgium). Skeletal patterns (Angle class I-II-III) were defined. Results: The mean value of the MSH in class I was 23.27±4.01 mm for the right side and 23.03± 4.07 mm for the left side. For MSL, the values for class I were 29.20±3.26 for the right and 30.04± 3.13mm for the left. The mean value of the MSH in class II was 21.73±3.44 mm for the right and 19.61± 2.22 mm for the left. MSL in class II was 26.57±2.31 for the right and 26.96±3.41mm for the left.  The average right MSH for class III was 22.90±0.62 mm, whereas the left side had a mean of 19.61±2.22 mm. Conclusion: Class I individuals exhibited the greatest MSH and MSL values bilaterally compared to Class II and III. Overall, maxillary sinus dimensions showed variation across skeletal classes, with Class II presenting the lowest averages.
