Occlusal Interferences Removal Influenced the Condylar Angular Inclination in Patients with TMJ Internal Derangement
Keywords:Cadiax, T-Scan, Occlusal interferences, condyle inclination, Bennett angle.
The aim of the Study: is to discuss the role of occlusal interferences on angular condylar inclination
in patients with TMJ internal derangement. And to demonstrated that the digital guiding of the
selective digital occlusal adjustment (enameloplasty) are more accurate and time saving.
Materials and Methods: Eighty-four patients with full dentition and angle class I diagnosed
with DC/TMD criteria, teeth contact registered digitally by using T-Scan NOVUS device, Cadiax
Compact II axiographic device was used to control the Sagittal Condylar Inclination (SCI) and
Bennett angle (BA) before and after occlusal interventions (occlusal adjustment and occlusal
Results: Eighty-four patients (76.2% females: 23.8% male) were participated in this study
with age range (19-45 years old), highly prevalence of occlusal interferences was reported. No
significant differences in (SCI) before and after occlusal interventions, Bennett angle demonstrated
a significant difference before and after occlusal interventions.
Conclusion: The Transverse Condyle Inclination (Bennett angle) highly influenced by the occluding
teeth. Enameloplasty that had been done in this study showed significant effects on Bennett angle.
Therefore, any full mouth rehabilitation should be carefully evaluated to avoid abnormal condylar
inclination and result in abnormal joint structures relationship.
