Deep bite -An insight

Deep bite is one of the most common malocclusion which affects children and even adults leading to a number of oral health problems. Patients with deep bite encounter periodontal and temporomandibular problems. Deep overbite refers to the increase of overlap of maxillary incisors over mandibular incisors beyond normal coverage of 30-40%. There are many factors which lead to the development of deep bite like inherent and acquired factors. Inherent factors like tooth morphology, skeletal patterns, rotation of condyle affects the bite. Acquired factors like muscle habits, loss of posterior tooth support or lateral tongue thrust may affect the bite. Deep bite can be corrected by number of different methods which include intrusion of anterior teeth, extrusion of posterior teeth or a combination of both. In non-growing patients surgical treatment is a suitable option to achieve stable results.This article describes various appliances and their biomechanics involved for correcting deepbite malocclusion
