Objective:
To study the condylar position of post-orthodontic patients with class II malocclusion.
Methods:
Forty four patients with class II malocclusion were recruited, among whom 22 were given orthodontic treatment and 22 without any treatment as controls. The condylar distractions between centric relation (CR) and centric occlusion (CO) were measured by an Panadent articulator with Measurement of Condylar Displacement (MCD).
Results:
There was no significant difference in condylar position between the two groups. Most condylar distractions happened to the posterior-inferior direction and were clinically acceptable. The amount of distractions was not correlated with Class II elastics.
Conclusion:
There is no enough evidence to show that traditional orthodontic treatment impacts the condylar position in patients with Class II malocclusion. However, attention still needs to be paid to condylar position in order to achieve a functional occlusion.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
