In mild class III cases, the patient is quite accepting of the aesthetics and the situation is monitored to observe the progression of skeletal growth. [54] Maxillary and mandibular skeletal changes during prepubertal, pubertal and post pubertal stages show that class III malocclusion is established before the prepubertal stage. [55]
Angle classification: Class II Division 1 Angle classification: Class II Division 2 Angle classification: Class III. Angle's Classification is devised in 1899 by father of Orthodontic, Dr Edward Angle to describe the classes of malocclusion, widely accepted and widely used since it was published.
If the CR shows a less severe class 3 malocclusion or teeth not in anterior crossbite, this may mean that their anterior crossbite results due to dental interferences. [ 17 ] Goal to treat unilateral crossbites should definitely include removal of occlusal interferences and elimination of the functional shift.
Class 2 and class 3 malocclusion with skeletal abnormalities. Patients with adequate spacing in dentition; Cases of anodontia/oligodontia; Patients with open bite and deep bite; In cases of midline diastema; Class 1 malocclusion with minimal space deficiency; Unerupted malformed teeth e.g. dilacerations; Extensive caries or heavily filled first ...
Class 3 elastics are used when the molar relationship is close to Class 1 malocclusion. Class 3 malocclusions due to skeletal discrepancy (mandibular prognathism) cannot be corrected with Class 3 elastics. [8] It is important to evaluate soft tissue and hard tissue esthetics of a patient
In instances when the maxillary anterior teeth are lingual to the mandibular teeth, the condition is referred to as an anterior crossbite. In some cases, this arrangement of teeth may indicate a displacement of the mandible relative to the maxilla and is called Class III or Pseudo-Class III malocclusion. Normal occlusion is Class I occlusion.
A dentist must complete 2–3 years of additional post-doctoral training to earn a specialty certificate in orthodontics. There are many general practitioners who also provide orthodontic services. The first step is to determine whether braces are suitable for the patient. The doctor consults with the patient and inspects the teeth visually.
Class II and III molar and incisor relationships are thought to be forms of malocclusion, however not all of these are severe enough to require orthodontic treatment. The Index of Orthodontic Treatment Need is a system that attempts to rank malocclusions in terms of significance of various occlusal traits and perceived aesthetic impairment. [ 11 ]
