Comparative analysis of the retention of maxillary denture base with and without border molding using zinc oxide eugenol impression paste.

Kaur S, Datta K, Gupta SK, Suman N - Indian J Dent (2016 Jan-Mar)

Bottom Line: On both trays, the final impression was made with zinc oxide eugenol impression paste.Mean force with border molding (2765.0 g) was larger than mean force without border molding (1805.0 g) at P < 0.01 level.In terms of percentage, too, the mean improvement (59.4%) in force of dislodgement was statistically highly significant (i.e. P < 0.01).

ABSTRACT

Aims and objectives: The purpose of the study was to determine the effect of border molding on the retention of the maxillary denture base.

Materials and methods: Two special trays, one with full extensions to the periphery and one 2 mm short from the borders were made on the cast obtained from the preliminary impression. Border molding was done on the tray which was short from borders. On both trays, the final impression was made with zinc oxide eugenol impression paste. Heat cure denture bases were fabricated on the prepared casts and retention was measured using specially designed instrument.

Observations and results: Mean force with border molding (2765.0 g) was larger than mean force without border molding (1805.0 g) at P < 0.01 level. In terms of percentage, too, the mean improvement (59.4%) in force of dislodgement was statistically highly significant (i.e. P < 0.01).

Clinical significance: The results of the present study suggest that the dentures made with border molding will provide better retentive force than the dentures made without border molding.

Mentions: Heat cure acrylic resin bases were fabricated on both the casts with two raised horizontal platforms in the region of the second premolar and first molar. The denture bases were finished and polished. Holes were drilled in the raised platforms, and a straightened wire of 26 gauge was passed through the holes and tied on one side [Figure 5a and b]. The denture bases were distributed into two groups of 20 specimens each and retention was compared.
