1. Retraction Retraction - (from lat. retractio tightening, reduction) means the reduction of cells, tissue, or other morphological formation due to the reduction (shortening) of certain elements of its structure. Indications for retraction: Taking dental impression of the dentition when making indirect restorations, with the ultimate line of preparation, located near or under the gingiva Cementation of the restoration with the final line of preparation, located near or under the gingiva The filling of carious cavities of 2 or 5 class according to Black Indications for retraction: Taking dental impression of the dentition when making indirect restorations, with the ultimate line of preparation, located near or under the gingiva Cementation of the restoration with the final line of preparation, located near or under the gingiva The filling of carious cavities of 2 or 5 class according to Black
