Gingival Retraction - Techniques and Materials: a Review
Though the necessity to place the finish line into the gingival sulcus obviously has a negative effect on the quality of the impression,4,8-10 aspects of gingival retraction have only been sparsely investigated.3-5 The aim of gingival retraction is to allow access for the impression material beyond the abutment margins and to create space for the impression material to be sufficiently thick. Te...
متن کاملComparative Review of Gingival Retraction Agents
In order to obtain an adequate impression of demarcation line area of a prepared tooth located in or below the gingival edge it is necessary to perform the dilatation and drying of the gingival sulcus using retraction cord impregnated with adequate retraction agents. The aim of the study was to carry out comparative analysis of advantages and disadvantages of commercially available gingival ret...

Gingival retraction or dilation is an important procedure in the fabrication of fixed prostheses. Quite often, the margins of these restorations are placed very close to the gingival margin, or even subgingivally, for aesthetic and functional reasons. Therefore, the operating surgeon must correctly record the prepared cervical finish line to enable adequate marginal integrity for the restoratio...
متن کاملDynamic Oxidoreductive Potential of Astringent Retraction Agents ( gingival margin retraction agents / cytotoxicity / human gingival fibroblasts )
The aim of this study was to evaluate the dynamics of the cytotoxicity of gingival margin retraction astringents based on aluminium chloride, aluminium sulphate, and ferric sulphate (solutions and gels) in human fibroblasts isolated from gingiva. The cytocompatibility of ten astringent-based chemical retraction agents: Gingiva Liquid, Alustin, Racestypine, Orbat sensitive, Astringedent®, Alusta...
متن کاملgingival retraction methods for fabrication of fixed partial denture:literature review
abstract fixed dental prosthesis success requires appropriate impression taking of the prepared finish line. this is critical in either tooth supported fixed prosthesis (crown and bridge) or implant supported fixed prosthesis (solid abutment). if the prepared finish line is adjacent to the gingival sulcus, gingival retraction techniques should be used to decrease the marginal discrepancy among ...
