Study on the angulation between the labial and lingual surfaces of anterior maxillary teeth for the creation of an innovative concept of an adjustable lingual brace

Introduction: The lingual appliance is genuinely an aesthetic device since it is positioned on the lingual surface of the tooth and thus is referred as ‘The invisible brace’. In comparison to labial appliances, lingual appliances have encountered challenges with sophisticated laboratory procedures, uneven lingual tooth morphology, high cost, and bonding trouble over time. The aim of this study was to develop a pre adjusted lingual bracket system that will be as efficient as labial orthodontics and can remove laboratory dependency. To accomplish it two parameters namely labiolingual angulation and labiolingual width were studied with the help of cast analysis. Material & Methods: Sample consists of 100 Dental Cast (Maxillary & Mandible) of patients aged 16-20 years which were selected on the basis of Angle’s Class I molar relationship without any crowding, rotation, attrition, abrasion, erosion, abfraction & anomaly on any tooth. Dental models / Impression were made at Santosh Dental College, Ghaziabad and were immediately poured by Orthokal at normal room temperature. Two important parameters were studied to develop the concept of New Pre Adjusted Lingual Bracket.
