What is molar relationship?
Molar relationship: The molar relationship shows the mesiobuccal groove of the mandibular first molar is DISTALLY (posteriorly) positioned when in occlusion with the mesiobuccal cusp of the maxillary first molar.
What are the four classifications of malocclusion?
Different Types of Malocclusions
- Overcrowding. Overcrowding is a common condition typically caused due to lack of space resulting from overlapping or crooked teeth.
- Spacing.
- Openbite.
- Overjet.
- Overbite.
- Underbite.
- Crossbite.
- Diastema.
What is end on molar relationship?
When molars and canines are positioned between Class I and Class II, the relationship is considered to be end to end. These Class II malocclusions are less severe versions of the full Class II occlusion (Fig. 1.4) and are considered Class II malocclusions when assigning Angle Classification.
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 molar occlusion?
Occlusion refers to the alignment of teeth and the way that the upper and lower teeth fit together (bite). The upper teeth should fit slightly over the lower teeth. The points of the molars should fit the grooves of the opposite molar.
What is class1 bite?
Class I is a normal relationship between the upper and lower teeth and jaws, or balanced bite.
What is class 3 bite?
Class III bites are often referred to as an underbite. This occurs when the lower molars are positioned more towards the front of your mouth than the upper molars. As a result, your lower teeth and jaw project out beyond the upper teeth and jaw.
What is a dental Class 3?
Class 3: Patients who require urgent or emergent dental treatment. Class 3 patients normally are not considered to be worldwide deployable. Treatment or follow-up indicated for dental caries, symptomatic tooth fracture or defective restorations that cannot be maintained by the patient.
How much is leeway space?
The result is that each side in the mandibular arch contains about 2.5 mm of what is called leeway space, while in the maxillary arch, about 1.5 mm is available on the average. When the second primary molars are lost, the first permanent molars move forward (mesially) relatively rapidly, using the leeway space.
