title: Improving reversible hydrocolloid impressions of subgingival areas.
abstract: The causes usually given for not having success with reversible hydrocolloid are that the impression material that goes beyond the subgingival margins often tears on removal and that the syringe material sets too fast. Both of these problems can be overcome and an extremely high rate of success can be obtained by following the technique described.
