Noteworthy Abstracts of the Current Literature The effect of different adhesive materials on retention of maxillary complete dentures. Figueiral MH, Fonseca PA, Pereira-Leite C, Scully C. Int J Prosthodont 2011;24:175-7. The aims of this study were to evaluate the retentive effect of different denture adhesives on maxillary complete dentures and examine the use of an intraoral transducer in assessing denture retention. The quantification of maxillary complete denture retention in 26 patients with five different adhesives was completed using vertical tensile tests and an intraoral resistance transducer. The means of the values obtained were analyzed statistically for comparative purposes. The experimental design revealed that all tested denture adhesives improved retention and that the intraoral transducer used proved to be appropriate for this evaluation. The intraoral transducer demonstrated that denture adhesives can improve retention of complete maxillary dentures. Reprinted with permission of Quintessence Publishing.
