Abstract:
Tissue dilation is one of the key factors in obtaining accurate duplication of subgingival finishing lines and hence excellent marginal adaptation of the restoration. Elastic impression materials do not displace the tissue. Therefore, the tissue must be displaced away from the prepared teeth or a small ribbon of the free gingiva must be removed to expose the finishing line before making the impression.
