Rings or Chains 4. Auxiliaries TOGETHER IN A HARMONY BETWEEN “ function and esthetics ” www.indiandentalacademy.com PowerPoint Presentation: HISTORICAL PRESPECTIVE FIXED APPLIANCES INTRODUCED IN 1800’s BANDING OF ANTERIOR &POSTERIOR TEETH BONDING OF ANTERIOR ATTACHMENTS www.indiandentalacademy.com PowerPoint Presentation: REDUCTION OF BRACKET SIZES CERAMIC /COMPOSITE BRACKETS COMPOSITE ARCHWIRES LINGUAL ORTHODONTICS INVISALIGN SYSTEM www.indiandentalacademy.com PowerPoint Presentation: ANTERIOR BAND1NG : www.indiandentalacademy.com PowerPoint Presentation: TWIN BRACKETS MINI-TWIN BRACKETS www.indiandentalacademy.com PowerPoint Presentation: DESIGN VARIATIONS www.indiandentalacademy.com PowerPoint Presentation: TOOTH COLOURED BRACKETS PLASTIC BRACKETS introduced by NEUMAN (1969) Acrylic, nylon, epoxies, polysulphones, polycarbonates USED IN a. Minimal torque situations b.Treatment of short duration STEEL SLOTED PLASTIC BRACKETS ----BEST SUITED www.indiandentalacademy.com PowerPoint Presentation: ADVANTAGES 1.Nontoxic 2.Easy fabrication 3.Good abrasion resistance 4.Good impact strength 5.No bad odour /distaste DISADVANTAGES 1.Lack of strength 2.Wire - slot wear 3. Water absorption & degradation 3.Discoloration and staining 4.Poor dimensional stability www.indiandentalacademy.com PowerPoint Presentation: 2.CERAMIC BRACKETS FULL CERAMIC BRACKETS CERAMIC BRACKETS WITH METAL INSERTS Introduced by MICHEAL SWARTZ (1987) www.indiandentalacademy.com PowerPoint Presentation: Full ceramic brackets With metal inserts www.indiandentalacademy.com PowerPoint Presentation:  MONOCRYSTALLINE /POLYCRYSTALLINE ALUMINA ( 2100`C ) ZIRCONIA (1000`C ) ------ Made of 3D inorganic molecules Extremely high hardness and compressive strength. Both are highly biocompatible www.indiandentalacademy.com PowerPoint Presentation:  BONDING OF CERAMIC BRACKETS TO ENAMEL: 1 . Mechanical retention via indentation / undercuts in base. 2. Chemical bonding with silane coupling agents. www.indiandentalacademy.com PowerPoint Presentation: DISADVANTAGES * Fracture of brackets * Friction within bracket slots * Tooth wear on bracket contact 1. BRACKET FAILURE 2. BULK OF THE BRACKETS 3. SURFACE ROUGHNESS 4. INHIBITION OF POLYMERISATION 5. DEBONDING DIFFICULTIES * ENAMEL DAMAGE * Pulpal damage www.indiandentalacademy.com PowerPoint Presentation: CASE SELECTION CRITERIA 1.Deep bite cases 2.Bruxism patients 3.Large restorations 4.Need for significant torque 5.Children Ceramic brackets are contraindicated in www.indiandentalacademy.com PowerPoint Presentation: 3.COMPOSITE BRACKETS A Composite is a multiphase material brought about by combining materials that differ in composition /form to obtain specific characteristics and properties. The constituents retain their identities and properties. Can be simplified as ‘ dispersion of fillers (particles /fibres /whiskers ) in a binder or matrix (metals /ceramics /resins)’. Reinforcement of polymer with ceramic\ metals –most common combination in ORTHODONTICS www.indiandentalacademy.com PowerPoint Presentation: COMPOSITION COMPOSITE PRECURSOR -Plasma treated high strength Polyethylene fibers REINFORCED WITH 1.Glass 2.Mineral filler 3.Metal 4.Ceramic liner 5.Metal liner Manufactured by ‘ INJECTION MOLDING TECHNIQUE’. www.indiandentalacademy.com PowerPoint Presentation: ADVANTAGES 1.SUPERIOR IMPACT RESISTANCE 2.INCREASED COMPRESSIVE STRENGTH 3.FATIGUE RESISTANCE 4.RESISTANCE TO DISCOLORATION 1.CREVICE CORROSION 2.DISINFECTION PROBLEMS 3.DIFFICULTY TO DETECT CRACKS 4.EXPENSIVE & CANNOT BE RECYCLED DISADVANTAGES www.indiandentalacademy.com PowerPoint Presentation: ARCH WIRES-COSMETIC ADVANCES Arch wires with plastic tubing \coating Marsenol Lee-white Composite archwires Optiflex archwires Fibre reinforced composite www.indiandentalacademy.com PowerPoint Presentation: ARCH WIRES WITH PLASTIC TUBING \COATING : DISADVANTAGES Earliest to be introduced 1.
