comparative study to evaluate the effect of high impact acrylic resin on the abutment structure of partial denture cases

Research Abstract

In this study, a comparison was done between the effect of high impact acrylic resin and conventional acrylic resin on the periodontal structures of the abutment teeth supporting partial denture. Twenty class II mandibular cases were selected for this study and divided into two equal groups of 10 cases each: Group I: mandibular cobalt-chromium partial denture with a conventional acrylic denture base resin. Group II: mandibular cobalt-chromium partial denture with a high impact acrylic denture base resin. Three parameters were used to evaluate the effect of the denture base material: a. Crevicular fluid b. Pocket depth c. Gingival index The measurements were carried at time of insertion,2 weeks,4 weeks,6 weeks and 8 weeks from time of insertion. The recorded measurements were statistically analyzed. The results of this study revealed that the rate of change between the two groups in the crevicular fluid was more for the high impact acrylic resin, while in the pocket depth, it was more for the conventional acrylic resin. Results of the gingival index scores were nearly parallel to that of the pocket depth.
