bracket | attachment that's bonded to enamel and used for holding wire arch |
elastomer | elastoplastic ring/latex elastic used to hold arch wire in brackets |
ligature | cord, thread, elastic arch stainless steel wire used to secure arch wire to bracket |
retainer (Hawley) | removeable plastic and wire appliance used to stabilize teeth either during or after orthodontic therapy |
cemented bands and bonded brackets advantages | improved aesthetics, better access for homecare, proximal caries can be detected, pt. awareness of loose brackets, ease of placement |
clinical bonding procedures | clean tooth surface, conditioning enamel surface: isolate, dry tooth, apply acid etch, rinse and dry apply bonding agent |
disease control | interdental areas: dental floss with floss threader, tufted floss, interdental brush, toothpick in holder |
what tool is used for debanding | pliers |
name 5 debonding methods | mechanical, electrothermal, Co2, YAG lasers, ultrasonics |
debonding | remove in 1 piece to avoid aspiration of brackets |
what to do after debonding with residual resin adhesive removal | exam: pt. reports, visual, tactile removal: tungsten carbide, finishing bur final finish: aluminium oxide, slurry |
retention (types of retainers) | removeable retainer Hawley, fix retainer, invisalignb/essix |
preventative care | fluoride prevents demieralization, etched enamel not covered by adhesive, use fluoride because uptake is increased |
