Abstract

Objectives: To evaluate the morphological characteristics of the pterygomaxillary suture in edentulous Vietnamese patients using CBCT imaging. Materials and methods: A cross-sectional descriptive study was conducted on 60 CBCT scans of edentulous maxillary patients, collected from the Faculty of Odonto-Stomatology, University of Medicine and Pharmacy at Ho Chi Minh City, and Van Hanh General Hospital. The analyzed parameters included the height of the pterygomaxillary suture, the distance from the maxillary tuberosity to the base of the pterygopalatine fossa, and the suture width at three levels (low, middle, high). Results: The mean height of the pterygomaxillary suture was 13.56 ± 2.44 mm in males and 12.97 ± 2.65 mm in females, with no significant difference between sides. The distance from the maxillary tuberosity to the base of the pterygopalatine fossa was 18.44 ± 2.73 mm in males and 19.27 ± 2.78 mm in females. The width of the pterygomaxillary suture decreased with height, with the largest width at the low level (8.18 ± 1.52 mm in males, 7.18 ± 1.46 mm in females) and the smallest at the high level (5.68 ± 1.38 mm in males, 5.29 ± 1.34 mm in females). Conclusion: The pterygomaxillary suture provides sufficient volume for pterygoid implant placement. The suture at the low level is wider than at the middle and high levels. CBCT assessment should be conducted for each patient to determine an appropriate surgical strategy.
