Resumen
There is a lack of clinical studies evaluating techniques of functional impression for
partially edentulous arches. The aim of this double-blind non-randomized controlled
clinical trial was to compare the efficacy of altered cast impression (ACI) and direct
functional impression (DFI) techniques. The efficacy was evaluated regarding the
number of occlusal units on denture teeth, mucosa integrity at 24-hour follow-up and
denture base extension. The sample included 51 patients (female and male) with
mean age of 58.96 years treated at Dental Department of UFRN. The patients,
exhibiting edentulous maxilla and mandibular Kennedy class I, were divided into two
groups (group ACI, n=29; group DFI, n=22). Clinical evaluation was based on the
number of occlusal units on natural and/or artificial teeth, mucosa integrity at 24-hour
follow-up, and denture base extension. Statistical analysis was conducted using the
software SPSS 17.0® (SPSS Inc., Chicago, Illinois). Student T-test was used to
reveal association between number of occlusal units and impression technique while
chi-square test showed association between mucosa integrity and impression
technique. Fischer s exact test was applied for association between denture base
extension and impression technique at 95% level of significance. No significant
difference was observed between the groups regarding number of occlusal units,
mucosa integrity and denture base extension. The altered cast technique did not
provide significant improvement in comparison to the direct technique when the
number of occlusal units, mucosa integrity and denture base extension
