Figure 4From: Development of a new quantitative gas permeability method for dental implant-abutment connection tightness assessment Experimental set-up tightness. Three tests were realized to assess experimental set-up tightness: -blind-ended glass tube; - epoxy: a double-ended opened glass tube sealed on one side with a plug of epoxy glue; - wax: a double-ended opened glass tube sealed on one side with a plug of wax.Back to article page
