CPD/Clinical Relevance: To demonstrate the outcome of a case of skeletal anterior open bite treated with orthognathic surgery.
An anterior open bite is an inability of maxillary and mandibular anterior teeth to contact or overlap in a centric relation.1 Abnormal growth, trauma, heredity, habits or tongue position, septum problems, enlarged tonsils and adenoids are proposed aetiologies.2 Various treatment options include vertical pull head gears, posterior bite blocks, functional appliances, multi-loop edgewise appliance or orthognathic surgery, depending upon the age of the patient. Jaw imbalances and improper bites in growing age groups can be treated with head gear and functional appliances, while adult age groups are usually treated with orthognathic surgery to improve function and aesthetics.
