Composite Techniques

Make sure you are working in a clean, dry surface

If needed, use a FlexiDiamond Strip. If at the gingival, use a narrow strip, if in the body, use a wide strip

Measure for symmetry

Etch the tooth to middle third of tooth both facially and lingually

NOTE: Frosty Etched Surface

Notice lack of etch

Bonding agent after curing for 20 seconds

Renamel Microfill rolled into a convenience form

Facial application of Microfill

Facial application of Microfill

Labial wall cured for 60 seconds

Lingual view

Notice lingual shelf

Application of Renamel Microfill to lingual shelf

Measure before finishing

Contour using the ET9 bur from composite to tooth

Contour the lingual of tooth using the OS1 carbide from composite to tooth

FlexiDisc Medium

FlexiDisc Fine

FlexiStrip Course/ Medium Narrow

FlexiStrip Fine/SuperFine Wide. Now that we are done polishing we are ready to start the second tooth.

After etching and placement of bonding agent, Renamel Microfill is placed and sculpted, using the 8A instrument without matrix

Defining interproximal

After polymerization of facial surface, apply a layer of Renamel Microfill to the lingual surface

Use the IPC-T to contour material interproximally

Use the IPC-T to remove any extra composite interproximally.

The thinness of the FlexiDisc Medium helps to round out the incisal embrasure

Using the 8A instrument we torque the teeth and insert the FlexiDiamond Strip

Use the 8392-016 to define gingival margins

Use the 8A instrument to retract the tissue, Brasseler’s 8392-016 bur is used to refine the subgingival margin

Final polish accomplished with FlexiDiscs, FlexiPoints, Enamelize polishing paste and FlexiBuffs

DIASTEMA CLOSURE

In restorations involving diastema closures, it is very important to measure the centrals for symmetry and tooth proportion before you begin adding composite. This restoration only requires the use of a microfill composite (Renamel Microfill, Cosmedent) because we are replacing enamel only. (Note that a microhybrid composite is not needed for this case.)

Start your diastema closure with facial application first because this will make it easier for you to set up the midline. Make sure to polymerize the facial for 20 seconds before moving to the lingual surface. Then fill in the lingual aspect of the tooth again with a microfill composite. Sculpt, shape and polymerize for 60 seconds. Make sure to measure your restoration again before finishing. Next contour, finish and polish the first tooth through completion before you start on the second tooth.

Once polishing is completed you may start working on your second tooth, building the tooth to the contact of the adjacent tooth. Note that you do not need to use a mylar strip when applying material to the second tooth because once the first tooth is polished the adjacent tooth will not stick to the new composite material.
