- 5. To provide idealized tooth position prior to appliance removal Allow the teeth to settle to Andrews non Orthodontic normals www.indiandentalacademy.com
- 6. Single prescription with overcorrection in all planes of space "Six Keys to Normal Occlusion" www.indiandentalacademy.com
- 8. Key : canine & premolars Center of bracket at max convexity of crowns on posterior teeth. (center of CC) Canine bracket more incisally 1 mm + lateral incisors Central incisors = lateral incisors www.indiandentalacademy.com
- 9. Andrews 50 Andrews -90 X 2 www.indiandentalacademy.com
- 11. Most variable Centre occlusogingivally & mesiodistally To offset the rotation accompanying distal traction Andrews 20 samewww.indiandentalacademy.com
- 12. 1-1.5 mm higher incisally than the rest of occlusal plane Andrews -70 reciprocal effect of building more positive torque into the incisors 2° more distal tip They are being retracted in most treatment + 20 www.indiandentalacademy.com
- 13. 1-1.5 mm shorter than maxillary canine tip.(To eliminate the need to place reverse and compensating bends into the finishing wires) Andrews 70 & 30 Same www.indiandentalacademy.com
- 15. Mesiodistally – prominent buccaal developmental ridge (long axis) Occlusogingivally – maximum convexity (center of CC) www.indiandentalacademy.com
- 16. 3° distal tip from normal (20) Entire buccal segment These teeth settle more mesially than the uppers & simultaneously rotate mesially thus necessitating extra distal rotation www.indiandentalacademy.com
- 17. 0.5-1 mm higher than the rest of occlusal plane same Andrews 50 www.indiandentalacademy.com
- 18. 0.5-1 mm more incisal than canine tip (level COS) same www.indiandentalacademy.com
- 20. Size and shape of teeth Accessibility of tooth Patient comfort and the frequency of bracket wing breakage. www.indiandentalacademy.com
- 22. Twin brackets (Diamond brackets) www.indiandentalacademy.com
- 33. Maxillary Arch Centrals X Laterals X – 0.5mm Cuspids X + 0.5mm Bicuspids X 1st Molars X – 0.5mm 2nd Molars X – 1.0mm Mandibular Arch Centrals X – 0.5mm Laterals X – 0.5mm Cuspids X + 0.5mm Bicuspids X 1st Molars X – 0.5mmwww.indiandentalacademy.com
- 34. Banding (Incisal edge reference) Maxillary Arch Centrals 3° Laterals 6° Cuspids 6° Bicuspids and Molars 0° Mandibular Arch Centrals 00 Laterals 00 Cuspids 6° Bicuspids 0° 1st Molars – 6° 2nd Molars 0° www.indiandentalacademy.com
- 39. Disadvantages of additional anterior tip Significant drain on A/P anchorage. Increased the tendency to bite deepening during alignment stage. Brought upper canine root apex too close to the first premolar root in some cases. www.indiandentalacademy.com
- 40. For maxilla Central incisors 5mm Lateral incisors 4.5mm Canine 5mm 1st bicuspid 4.5mm 2nd bicuspid 4mm 1st molar 3mm 2nd molar 2mm For Mandible Central incisors 4mm Lateral incisors 4mm Canine 4.5mm 1st bicuspid 4mm 2nd bicuspid 3.5mm 1st molar 2.5mm 2nd molar 2.5mm www.indiandentalacademy.com
- 42. Torque is not efficiently expressed owing to two reasons: The area of torque application is small and depends on the twist effect of a relatively small wire compared with the bulk of tooth. Because full thickness wire will prevent sliding .019/.025 steel wires in .022 slot are used. These wires have ‘slop’ of about 100 depending on the tolerances in bracket and wire manufacturing and the amount of wire edge ‘rounding’ or ‘radiusing’ www.indiandentalacademy.com
