Alternative Terms for Open Bite
An open bite is also referred to as "anterior open bite" (AOB) in clinical literature, which is the most common alternative term used in orthodontic and dental practice. 1, 2, 3
Primary Terminology
- Anterior open bite (AOB) is the standard alternative term used throughout orthodontic literature to describe this malocclusion 2, 3, 4
- The term specifically refers to the lack of vertical overlap between upper and lower anterior teeth during maximum intercuspation 4
Clinical Descriptors Based on Severity
- Simple open bite describes cases limited to the anterior region that may resolve spontaneously during the transition from mixed to permanent dentition 5, 6
- Complex open bite or severe skeletal anterior open bite refers to cases extending into the premolar and molar regions that typically require orthodontic or surgical intervention 2, 5
- Skeletal anterior open bite specifically indicates cases where the etiology involves underlying skeletal growth abnormalities rather than purely dental factors 2
Descriptive Clinical Features
- The condition may be described by its characteristic presentation: malocclusion with open bite 1
- In the context of cardio-facio-cutaneous syndrome, it appears alongside posterior crossbite as part of a characteristic dental phenotype 1
- The term vertical malocclusion is sometimes used when emphasizing the dimensional aspect of the deformity 5
Important Clinical Note
The terminology used often reflects the underlying cause—whether the open bite results from dental factors (habit-related), skeletal abnormalities, or soft tissue dysfunction—which directly impacts treatment planning 5, 6
