Abstract
  • Objective: The primary objective was to examine if a cordless gingival displacement procedure displaces sulcular tissue to facilitate acceptable impressions for fixed prosthodontic restorations. Materials and Methods: Fifteen (15) patients were recruited; cordless impressions (n=7) and conventional corded impression (n=8) were made during routine treatment for fixed dental prostheses. Results: Fisher’s exact tests, Wilcoxon rank sum tests, and an unpaired t-test were used to compare variables between (CD) and (CL) groups, and to compare variables between acceptable and unacceptable impressions. Level of significance was set at 0.05 for all analysis. Within this small sample size, the 2 groups (CD and CL) are significantly similar in relation to most variables. Only TEAR and EVAL were significantly different between CD and CL, and VOID was significantly different between acceptable and not acceptable impression groups. Conclusions: Within the limitations of this study, marginal tearing statistically affected the acceptance of impressions made using the cordless procedure.
