Study Notes
Analyzing and Planning Oral Rehabilitation
- Registration of individual articular parameters, such as SCI, Bennett angle, and immediate side shift (ISS), is the first step for analyzing and planning oral rehabilitation.
- These parameters are essential for maintaining and restoring functions like mastication, speech, chewing, and esthetics.
Significance of SCI
- SCI (Specific Condylar Inclination) is the angle formed between the protrusive condylar path and the Frankfort plane, or another horizontal reference plane.
- SCI mostly influences dynamic tooth morphology.
- Determining the individual value of SCI ensures better diagnosis, treatment planning, and more accurate prosthetic restorations, saving valuable clinical time.
Methods for Condylar Path Registration
- Several clinical, radiological, and instrumental methods have been proposed for condylar path registration.
- CBCT (Cone Beam Computed Tomography) is the most accurate and non-invasive method for measuring the curvature of the glenoid fossa.
- CBCT scan has the highest rate of reliability for measuring SCG angle.
Findings of the Clinical Study
- There is no statistically significant difference between the right and left condylar inclination values achieved by CBCT technique in both dentate and edentulous groups.
- There is no statistical significance variation in SCG values between genders.
- A statistically significant difference in the values of SCG inclinations was noticed between dentate and edentulous cases.
Comparison with Other Studies
- The findings are in agreement with other studies, except for El Gheriani and Winstanley, and Zamacona et al. who declared significant differences between the left and right condylar guidance values.
- The difference in results may be due to the heterogeneity of their samples, which included partially edentulous and completely edentulous participants.
- The outcome of this study disagrees with Das et al's study, which may be due to the use of OPG (Orthopantomogram) as a method for measuring SCG, which is less precise than CBCT.
