title: [The influence of heat/pressure polymerization method on the adaptation of complete denture base].
abstract: OBJECTIVE
  The purpose of this in vitro study is to investigate the mechanical ability and adaptation of complete denture base by the use of thermoformed resin cured with heat/pressure injection method.
  
  
  METHODS
  The flexural strength, the surface hardness and the adaptation of thermoformed resin and SR Ivoclar capsule resin were compared between using the conventional water bath-cured method and heat/pressure injection method. The collected date were analyzed statistically using the two-sample t test at alpha=0.05.
  
  
  RESULTS
  The thermoformed resin cured with heat/pressure injection method has significant difference from that cured with conventional water bath-cured method on flexural strength and surface hardness (P<0.05). The upper partial base had significant difference in the gap distance at point A, B, D and E (P<0.05) between the thermoformed denture base cured with heat/pressure injection method and conventional water bath-cured method.
  
  
  CONCLUSIONS
  These findings indicate that the thermoformed resin cured with heat/pressure injection method has better mechanical abilities and adaptation than that cured with conventional water bath-cured method.
