[Gingival retraction methods. A literature review]
Abstract
The exposure of the preparation margin and the control of the hemorrhage in the gingival sulcus are prerequisites for precise impressions and thereby improving the quality of indirectly fabricated restorations. The purpose of this review article is to summarize available evidence with respect to current methods of gingival retraction and to provide the clinician with practical tips.
