Clinical efficiency of novel collagen membrane derived from porcine pericardium

Abstract

Purpose : The aim of this study was to radiographically and clinically compare dimensional alterations during ridge preservation using two extracellular matrix (ECM) membranes.<br/> Methods : A widely used ECM membrane (Bio-Gide®) and newly developed ECM membrane (Lyso-Gide®) were applied during the ridge preservation procedure in control and test groups, respectively. Cone-beam computed tomography (CBCT) scans were taken at surgery day and 6 months after the ridge preservation procedure. Alginate impressions were obtained at 1 week and 6 months after the ridge preservation procedure. Results were statistically analyzed using the independent t-test and the nonparametric Whitney U test.<br/> Results : Change of extraction socket dimension from master casts showed no significant difference between two ECM membranes. Likewise, differences of width, height and quantity of bone tissue from CBCT scans showed no significant difference. The mean VAS of characteristics of test group was shown higher than that of control group.<br/> Conclusions : Newly developed ECM membrane in ridge preservation procedure showed comparable clinical/ radiographical result to widely used ECM membrane.
