areas. The facial embrasures are accentuated with the same fine-
pointed diamonds. The facial surfaces are also textured using
course and fine diamonds to give the proper surface texture given
the patient’s age and desired esthetic outcome.
Once the texturing and embrasure refinement has been done,
the bridges are fired in the oven. Further refinement of the embra-
sures and texturing is then done once it is in final crystalized state.
It is easier to see what the embrasures look like and the texture
by wetting the surface of the bridge. This can be done with water,
ceramic liquid or glycerin. By wetting the surface you can see
the effects of the texturing and how the embrasures look when
refined. Further texturing or refinement can then be done if so
desired. The liquid is then removed with soap and water.
Now that the bridges are refined, the first stain-and-glaze firing
is done. The stains and characterization are applied. B1 shade is
applied to the cervical area to add more chroma. It is important to
carry this cervical chroma into the interproximal area and into the
embrasures. By adding chroma facial embrasures, it gives the illu-
sion of depth that makes the embrasures look life-like and gives
the look of separate teeth instead of connected teeth. Blue is added
to the incisal to give the look of translucent enamel. The incisal
edges and line angles are highlighted with white. All of these tints
are blended in to make a subtle effect. The bridges are then fired
on the glaze setting to set the stains and characterizations. After
this, the glaze is applied and fired again. Once it is glazed, the
restorations are polished with Diashine and rag wheels to bring
it to a more life-like luster. The abutments are fired as well, and
everything is tried on the model (Fig. 17). The TiBases and abut-
ments are then bonded together with Multilink Hybrid Abutment
Cement per Ivoclar’s recommendations.
The patient returns for the insert of the abutments and bridges.
The screw-retained temporaries are removed, the abutments
are placed, and the screws lightly hand-tightened. If too much
tissue pressure is occurring, then the abutments can be adjusted
