Abstract

Horizontal condylar guidance angles obtained using two different methods: the clinical protrusive interocclusal record method and the radiographic method using CBCT (Cone Beam Computed Tomography). The key issue is the observed significant differences in the condylar guidance angles measured by the clinical method and those measured radiographically, with the radiographic measurements being consistently higher than the clinical ones. A total of 25 completely edentulous individuals were included, with condylar guidance angles measured clinically using the protrusive interocclusal record method and radiographically through CBCT in two formats. Results showed significant differences in the angles between the methods, with radiographic measurements being higher than clinical values. Strong correlations were observed between the clinical process and the CBCT panoramic and cross sectional views. The study concludes that CBCT measurements provide more precise condylar guidance angles than the protrusive interocclusal record method.
