title: Comparative evaluation of border molding using two different techniques in maxillary edentulous arches: A clinical study.
abstract: OBJECTIVE
  The aim of thisin vivostudy was to compare the single-step border molding technique using injectable heavy viscosity addition silicone with sectional border molding technique using low fusing impression compound by evaluating the retention of heat cure trial denture bases.
  
  
  METHODS
  Ten completely edentulous patients in need of prostheses were included in this study. Two border molding techniques, single-step (Group 1) and sectional (Group 2), were compared for retention. Both border molding techniques were performed in each patient. In both techniques, definitive wash impression was made with light viscosity addition silicone. The final results were analyzed using pairedt-test to determine whether significant differences existed between the groups.
  
  
  RESULTS
  Thet-value (3.031) infers that there was a significant difference between Group 1 and Group 2 (P= 0.014). The retention obtained in Group 2 (mean = 9.05 kgf) was significantly higher than that of Group 1 (mean = 8.26 kgf).
  
  
  CONCLUSIONS
  Sectional border molding technique proved to be more retentive as compared to single-step border molding although clinically the retention appeared comparable.
