Keywords:Gingival displacement, Copper band, Condensing silicone, Periodontal, Aluminium chloride
AbstractThis study carried out three dogs to gingival displacement comparing the copper band and compound gingival displacement and impression technique with string impregnated in aluminium chloride with gingival displacement technique, and single impression by condensing silicone impression material. The objective was to compare the periodontal biocompability between the two techniques. Blocks specimens including the teeth and the soft tissue were taken immediately, 0, 7, 14 and 21 days, and had histological analysis with stain hematoxilin and eosin. The results showed that all groups had reversible histological consequences.
