INCIDENCE OF DEEP BITE IN DENTAL CLASS 1 PATIENTS WITH VERTICAL MAXILLARY EXCESS SEEKING ORTHODONTIC TREATMENT

Abstract

Deep bite / Deep overbite is excessive vertical overlapping of mandibular incisors by the maxillary incisors in a centric occlusion. The incisal edges of the lower teeth should contact slightly at or above the cingulum of the upper teeth, which would be approximating 1-3mm overbite. Deep bite is the most common malocclusion in children and adults. The excessive overbite is a complex orthodontic problem that may involve a particular group of teeth or whole dentition or maxilla and mandible. This retrospective cross-sectional study was carried at the UG students clinic and Department of orthodontics. Case records of all the cases were tabulated and after applying the inclusion criteria 19 case records with Class 1 dental occlusion patients with vertical maxillary excess were collected. This data was tabulated and analysed in SPSS and descriptive statistics were performed. The results gave information that 68% of them were females showing high female predilection. Age limit was not mentioned because people of all ages were included in the study. Results showed less male predilection with 32% than females. The study concluded that most of the Female patients were incident to Deep bite in Dental Class 1 with vertical maxillary excess seeking orthodontic treatment. It is widely accepted that correction of deep bite is easier to accomplish and more stable when done on growing patients than those with no appreciable growth remaining. Adults often need only correction of excessive overbite either due to its isolated nature or a demand for limited treatment. In adults, this treatment is often part of periodontal, restorative or temporomandibular joint therapy.
