There
is erosion and sensitivity at the cervical margins of the
upper right lateral and canine sufficient to justify restoration
with glass-ionomer. |

The
cavity surface is conditioned with a 10 second application
of 10%polyacrylic acid, then washed vigorously and dried lightly. |

The
capsulated glass-ionomer is mixed and syringed to place.
As it is an auto cure material it is firmly adapted to place
using a soft tin matrix which was pre-contoured to fit this
position. |
 figure4 |
The
matrix will remain in position until the excess cement has
set firmly, at which time the matrix can be flicked off and
the glass-ionomer immediately covered with a thin layer of
a light activated resin bond. The bond will be light activated
and this will maintain the water balance until the cement
is mature. |

One
week later the restorations were reviewed to ensure there
were no overhangs. Note the colour match and translucency
that were satisfactory following maturation of the glass-ionomer. |

The
same restorations photographed 14 years after placement. There
has been a small amount of wear, mostly from surrounding tooth
structure. |
