What is the molar relationship with Class 1?

Classification of molar relationships (1) Class I (Class I molar relationship): The mesiobuccal cusp of the upper first molar is in occlusion with the mesiobuccal groove of the lower first molar (Figure 1A). Guidelines used for classifying molar relationships from the buccal aspect.

What is a Class 1 canine?

Class I: the cusp tip of the upper primary canine is in the same vertical plane as the distal surface of the lower primary canine. Class II: the cusp tip of the upper primary canine tooth is mesial to the distal surface of the lower primary canine.

Is Class 1 occlusion normal?

Class I is a normal relationship between teeth, jaw and jaw. This is the correct occlusion, and it gives the person a well-balanced profile in the anteroposterior plane.

What is a Class 1 malocclusion?

About 60% of affected individuals have a class 1 malocclusion. In this condition, the dental arches are in relative alignment with the skull, but the teeth are crowded. An overbite, also known as class 2 malocclusion, occurs when the lower jaw is underdeveloped.

Is first molar important?

From a functional and developmental point of view, the first permanent molars are the most important teeth, with a key role in occlusion. The first permanent molar has maximum root surface and so is the most important anchorage unit used in tooth movement.

How do you correct a Class 1 malocclusion?

Most class 1 malocclusions can be corrected with traditional orthodontic treatments such as metal or clear ceramic braces. Sometimes, a premolar tooth extraction may be required.

What causes malocclusion class1?

The malalignments associated with Class I malocclusion are often due to space loss and tooth movements, which often occur in the mixed dentition. Space loss and tooth movements lead to eruption problems and contact displacements that cause malalignments.

Can you live without first molar?

Yes, it is possible to lose a molar tooth and avoid problems with biting and chewing. However, a missing molar has the potential to cause problems with chewing food on the affected side of your mouth, and may also lead to receding gums.
