The quality of fixed prosthodontic impressions: An assessment of crown and bridge impressions received at commercial laboratories.

CONCLUSIONS:Marginal discrepancies made up the largest category of error noted in impressions evaluated. The authors noted an increase in errors at the finish line with dual-arch impression techniques and in the presence of blood.PRACTICAL IMPLICATIONS:Dentists have ethical, moral, and legal obligations bestowed on them by the profession and need to evaluate critically the work they send to laboratories. The authors strongly recommend an improvement in technique and reviewing of all impressions and working casts.
