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]
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.
However, this management technique may not be suitable for those with gum disease, parafunctioning activity (tooth grinding or clenching) or malocclusion. [ 74 ] It should also be noted that spaces within the dental arch should be monitored, especially in younger patients, as teeth are more likely to drift, tilt or over-erupt.
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.
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.
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
Orthodontics [a] [b] is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, as well as misaligned bite patterns. [2] It may also address the modification of facial growth, known as dentofacial orthopedics. Abnormal alignment of the teeth and jaws is very common.
This was used primarily in Class 2 Division 1 and 2. Frankel Appliance III (FR III) Used in patients with Class 3 malocclusion. In this appliance the lip pads are used in the maxillary arch to allow the maxilla to grow. The mandibular arch does not have pads in the anterior to allow the soft tissue forces to act on the mandible. [citation needed]
