Determination of mean Horizontal Condylar Inclination using semi-adjustable articulator and radiographic technique

Abstract

Background: In the prosthetic treatment, Determination of the accurate horizontal condylar path and mandibular movement of the patient is fundamental consideration of appropriate oral rehabilitation. Horizontal condylar inclination is determined by clinical and complementary methods. In 2012, PK Tannamala introduced horizontal condylar inclination by comparing clinical and orthopantographic methods. Aim: The aim of our study was to determine the mean angle of horizontal condylar inclination of the mandibular joint by comparing clinical and images in healthy youths. Materials and Methods: The study was conducted using a descriptive research method to determine the average values of the forward movement of the jaw and the angle of inclination of the jaw joint on plain radiographs in 40 people aged 20-25 years. Results: The horizontal condylar inclination of the temporomandibular joint in 40 people, the average value was 35.50±4.22° on the right side, the minimum value was 26.42°, and the maximum value was 41.03°. On the left side, the average value was 36.02±4.04°, the maximum value was 43.10°, and the minimum value was 25°. Conclusion: The mean horizontal condylar inclination was measured in a semi-adjustable articulator, which was 35.05±4.22° on the right side and 36.02±4.40° on the left side. Measurements on orthopantographic were 36.04±4.99° on the right side and 37.14±5.03° on the left side. According to the statistical parameters of the results, the p˂0.033 of the actual clinical examination method and the X-ray image of the right side showed a significant difference between the two groups. On the left, p˂0.016 was a significant difference between the two groups.
