Sectional Impressions and ‘Every Other Tooth’ Technique in FPD
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 1
Abstract
Gingival displacement procedure is an important component of fixed prosthodontics. It helps in delivery of the impression material subgingivally to record the finish line as well as the tooth contour apical to it, so as to produce restorations with closely adapted margins in harmony with the tooth anatomy and gingiva. While displacing gingiva with retraction cords, the health of the tissues must be maintained. In case of multiple anterior tooth preparations with close root proximity, placing the retraction cord simultaneously around all teeth will result in strangulation of interdental papillae. This can impair gingival health as well as cause black inter-dental triangles. To avoid this, ‘every other tooth’ technique of gingival displacement in combination with sectional impressions may be used to provide a better master cast in multiple tooth preparations. The present case report describes the use of this simple combination procedure for the restoration of lower six anterior teeth as a part of full mouth rehabilitation.
