Retentive forces of two mandibular base plates fabricated from compound and silicone: Study

ABSTRACT:Success of complete dentures largely depends on accuracy of impression. In fabrication of mandibular complete denture, border molding of an individual tray is an essential step in impression making. It can also trace the future denture’s periphery by molding the peripheral of the individual tray and by asking the patient to make functional trimming exercises. The individual tray obtained from a preliminary impression are border molded with modeling compound, and final impression is completed with easily flowable impression material such as zincoxide eugenol paste. By using this border molding and peripheral tracing impression technique, resultant mandibular complete denture favors good retention and stability even in resorbed alveolar ridge. Most prosthodontists accepted this method as a standardized method for complete denture construction. But it is time consuming and often difficult for beginners to master as it require skill and experience. In this study, high viscosity silicone (putty) and light body silicone have been introduced as a new border molding material. It was found that the retention of two base plates resulted from impression making with these two border molding materials were not statistically significant (mean 367 gf for compound and 368 gf for silicone). Silicone impression material has an excellent elasticity and acceptable working time in the mouth during functional trimming. It also has good dimensional stability, acceptable taste and ease of manipulation for every dentist.
