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 maintain stability of matrix band during condensa7on of restora7ons
• Has a guide slot, spindle, outer and inner knob
Matrix Band
• To replace missing proximal walls of cavity prepara7on for condensa7on
• of restora7ve material
• Universal, premolar, molar, and pediatric bands
Interproximal Knife
• 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)
Composite placement instrument
• Places composite on the surface of cavity
Contact forming instrument
• Forms the margins and contact points
Contouring instrument
• Used for creaCng contours on crown
Plas7c Instrument
• To carry composite material for cavity prepara7on, and shape composite, not for any other use
• Specially coated instrument, not for amalgam or any other use
Micro Brush
• Use to apply primer, den7n bond enamel bond, sealants
• Small plas7c instrument with small fiber bristled head
Mylar Strip
• Thin clear strip used to isolate cavity prep, able to use cure light
• Similar size to matrix band, clear
Composite Well
• Plas7c well used to hold composite, etch, bond, cavity condi7oner
• Plas7c well, smaller than amalgam well
Curing Light
• To harden light-‐cure materials, bonding, composites, sealants, cements, build up
• Material must be cured in increments of 2 mm or less, need to be above 300 wavelength
Protec7ve Eye Wear
• To protect operator’s and assistant’s eyes during procedures
• Orange, dark, clear, protects eyes
Finishing Strips
• To finish and smooth interproximal surfaces • Differs in grit, coarse, fine, extra fine. Abrasive
Bonding Agents
• 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
• Fluid like composite, with in a syringe used with a syringe 7p
• This presentaCon is prepared for the first year students in dental schools, to familiarize them with some basic informaCon regards dental restoraCve instruments.
