Alginate (two stage-two step final/wash impression) vs Silicone elastomer (two stage-two step)

Alginate (two stage-two step final/wash impression) may leads to higher participant-reported oral health-related quality of life… compared with silicone elastomer (two stage-two step) (low certainty).

  Silicone impressions 57.7% (41 participants), alginate impressions 23.9% (17 participants); both equally satisfactory for 7 (9.9%) and equally unsatisfactory for 6 (8.5%) (McNemar chi-square 12.02, 1 df, P = 0.0005).

Single-stage alginate impression (simplified method) vs Two stage-two step zinc-oxide eugenol (ZoE) traditional method

It is very uncertain whether single-stage alginate impression (simplified method) changes participant-reported quality of the denture (general satisfaction) compared with two stage-two step zinc-oxide eugenol (ZoE) traditional method (very low certainty).
