Abstract
- This study was undertaken to determine the adequate bracket slot torque degrees in Korean. The subjects were consisted of plaster casts of 30 male and 30 female. They had acceptable profile, normal occlusion, no loss of tooth and no experience of dental treatment. Labiohngual or buccolingual inclinations of individual tooth were estimated as +, - degrees on the fixed model by use of dental surveyor, contact angle gauge and measuring grid. The following conclusions were obtained 1. Adequate degrees of bracket slot torque in Korean were obtained. 2. The degrees of labiolingual or buccolingual inclination of every tooth were very variable according to the individuals. 3. Almost constant torque degrees were observed on the maxillary buccal segments. 4. Progressive increase in minus torque degrees were observed from the mandibular canines to the 2nd molars.
