Open bite is a type of orthodontic malocclusion which has been estimated to occur in 0.6% of the people in the United States. This type of malocclusion has no vertical overlap or contact between the anterior incisors. [1] The term "open bite" was coined by Carevelli in 1842 as a distinct classification of malocclusion.
An open bite malocclusion is when the upper teeth don't overlap the lower teeth. When this malocclusion occurs at the front teeth it is known as anterior open bite. An open bite is difficult to treat due to multifactorial causes, with relapse being a major concern. This is particularly so for an anterior open bite. [58]
2.e Anterior or posterior open bite >1mm but ≤2mm 2.f Increased overbite ≥3.5mm (without gingival contact) 2.g Pre-normal or post-normal occlusions with no other anomalies. Includes up to half a unit discrepancy Grade 1 (no treatment required) 1. Extremely minor malocclusions, including displacements less than 1mm [31]
Long face syndrome, also referred to as skeletal open bite, [1] is a relatively common condition characterised by excessive vertical facial development. [2] Its causes may be either genetic or environmental. Long face syndrome is "a common dentofacial abnormality." [3]: 369 [4] Its diagnosis, symptomology and treatments are complex and ...
Prevent relapses after orthodontic treatment; Improve the relationship between dental arches; reduce open bite and overjet; Maintain overall facial muscle tone needed for chewing, swallowing, and speech; Create an oral environment that creates favorable conditions for the development of dentition; Eliminate dry mouth condition or xerostomia
The first Twin Block appliances were fitted on September 7th 1977, when the patient was 8 years and 4 months old. The bite blocks were comfortable to wear, and treatment progressed smoothly, with the distal occlusion improving and the overjet decreasing from 9 mm to 4 mm within 9 months. [1] The treatment progression is as shown in Figures 7 and 8.
The most common and simple treatment is the construction of a specially made acrylic prosthesis that covers the biting surfaces of the teeth and protects the cheek, tongue, and labial mucosa (an occlusal splint). This is either employed in the short term as a habit-breaking intention or more permanently (e.g., wearing the prosthesis each night ...
An open bite is a condition where the upper and lower teeth do not meet or bite in the correct position. Unlike an overbite or underbite, there is no overlapping of teeth, giving an impression of the teeth appearing “open”. A mild case of open bite can be treated with Invisalign, a popular orthodontic treatment using clear aligners.
