Presented  by  Dr.  joaquin  masoud  C.  shafiee    

University  of  the  EAST  Post  graduate  school  

Department  of  prosthodonCcs  

Filling  paraphernalia    

Amalgam    

Amalgam  carrier    

•  Double-­‐ended  instrument  with  wells  on  both  ends  to  pack  fresh  amalgam  in  &  carry  to  prepped  tooth.  

•     

Amalgam  condenser  

•  also  known  as  a  plugger  that  is  used  to  press  the  silver  filling  into  place  

Serrated  condenser  

•  To  pack  and  condense  amalgam  into  cavity  preparaCon  

Smooth  condenser  

•  To  pack  and  condense  amalgam  into  cavity  preparaCon  

Interproximal  condenser  

•  To  pack  and  condense  amalgam  into  interproximal  areas  of  the  cavity  prepara7on    

Matrix  Band  •  In  caviCes  involving  more  than  one  tooth  surface,  it  is  usually  necessary  to  surround  the  tooth  with  a  matrix  band  to  help  confine  the  restoraCve  material  to  the  cavity  preparaCon  during  condensaCon.  The  matrix  band  also  helps  determine  proper  contours  and  the  locaCon  and  form  of  proximal  contacts  in  the  restored  tooth.    

Tofflemire/Matrix  Band  Retainer

•  To  Carve  interproximal  walls  of  amalgams,  to  restore  contour  of  proximal  walls  

•  Double  ended,  Sharp  carving  hard  metal  blade  

Wedges  

•  The  wedge  keeps  the  amalgam  from  squeezing  out  under  the  matrix  band  and  into  the  interproximal  space  or  spaces    

•  To  hold  matrix  band  in  place  along  gingival  margin  of  class  II  

•  Triangular  or  rounded  plas7c  or  wooden,  various  sizes  and  color  

Amalgam  burnisher  

•  Used  to  smooth  the  surface  of  fresh  placed  amalgam  restoraCon.  (Ball,  Football,  T-­‐shaped,  Beavertail)  

Football  burnisher  

•  To  smooth  Amalgam  aJer  condensing,  to  contour  matrix  band,  to  burnish  amalgam    

Acorn  Burnisher  

•  To  smooth  amalgam  aJer  condensing,  used  to  create  occlusal  anatomy,  burnish  amalgam    

T-­‐Ball  Burnisher  

•  To  Smooth  amalgam  aJer  condensing;  to  contour  matrix  band,  ini7ate  carving  and  occlusal  anatomy    

Beavertail  Burnisher  

•  To  smooth  amalgam  aJer  condensing;  to  burnish  the  lingual,  facial  amalgam  walls  of  a  restora7on    

Ball  Burnisher  

•  To  smooth  amalgam  aJer  condensing  To  contour  matrix  band  before  amalgam  placement    

carvers  

•  Remove  excess  material,  contour  surfaces,  and  carve  anatomy  back  into  amalgam  or  intermediate  restoraCon  b4  it  hardens.  (Discoid-­‐cleoid  for  occlusal,  Hollenback  to  remove  excess  material)  

Hollenback  Carver  

•  To  contour  and  carve  occlusal  and  interproximal  anatomy  in  amalgam  restora7ons    

•  Double  ended,  sharp  s7ff  metal  blade,  sharp  point;  ends  are  protrude  at  different  angles;  carves  other  restora7ve  materials  

Cleoid-­‐discoid    

•  Or  Discoid-­‐Cleoid  Carver  •  To  carve  occlusal  anatomy  into  amalgam  restora7ons  

•  Double  ended;  Discoid  is  disk  shaped;  cleoid  is  pointed,  sharp  

Dycal/LinerApplicator  

•  To  Place  Calcium  Hydroxide  or  Glass  Ionomer  

•  Has  short  or  long  handle,  similar  to  a  7ny  ball  burnisher    

Ar7cula7ng  Paper  Holder  

•  To  hold  ar7cula7ng  paper  in  checking  pa7ents  bite  

•  Ar7cula7ng  paper  is  blue  or  red,  thin  to  thick  

Woodson  

•  Used  as  a  burnisher  and  condenser  

•  Doubled  ended,  one  end  a  condenser  while  other  is  paddle  shaped  

Amalgam  knife    

•  Used  to  remove  excess  material  along  margin  where  material  and  tooth  structure  meet;  most  commonly  interproximal.  

Amalgam  well  

•  Where  newly  mixed  amalgam  is  placed  and  retrieved  from.    

Composite    

Composite  Placement  Instrument  

•  Made  to  place  composite  restoraCve  materials  to  prevent  scratching  the  composite  material  made  of  anodized  aluminum  or  Teflon.  (PlasCc  composite  instrument,  Metal  composite  instrument)

•  Acts  as  an  adhesive  between  the  tooth  and  the  composite  material  

 •  Differs  in  genera7on,  all  in  one  unit,  3  step,  2  step,  brands  require  different  techniques  

Etch  

•  To  remove  the  smear  layer,  prepare  the  tooth  for  bonding  

 •  Differs  in  color  and  pH  level.  Concentra7ons  of  Phosphoric  Acid  ~  typically  37  %  and  blue  

Composite  Shade  Guide  

•  To  allow  the  pa7ent  to  see  the  shade  they  would  like  the  filling  to  be.  

 •  Has  different  color  teeth  with  a  shade,  e.g.  A2,  B1,  C3,  D2.  

Packable  Composite  

•  Low  viscosity,  high  filler,  permanent  restora7ve  material  

 •  Either  in  a  syringe  or  composite  7p.  Composite  7p  requires  composite  gun  

Flowable  Composite  

•  High  viscosity,  low  filler  composite,  used  small  areas  or  before  placement  of  packable  composite,  differs  in  shade

•  This  presentaCon  is  prepared  for  the  first  year  students  in  dental  schools,  to  familiarize  them  with  some  basic  informaCon  regards  dental  restoraCve  instruments.
