Effect of a Denture Adhesive on the Satisfaction and Kinesiographic Parameters of Complete Denture Wearers: A Cross-Over Randomized Clinical Trial

Abstract

The aim of the present study was to assess the effect of a denture adhesive (DA) on patient satisfaction and kinesiographic parameters of complete denture wearers by a cross-over study. Fifty edentulous patients received a set of new complete dentures. After an adaptation period, the participants were enrolled in the trial and randomized to receive a sequence of treatment protocols: Protocol 1- DA use during the first 15 days, followed by no DA for the next 15 days; Protocol 2- no DA during the first 15 days, followed by use of DA for the next 15 days. Outcomes were assessed after 15 days of each sequence of treatment. A questionnaire was used to assess the patients' satisfaction. A kinesiograph was used to record mandible movements and patterns of maxillary complete denture movement during chewing. The Wilcoxon test (α=0.05) and a paired sample t-test (α=0.05) were used to compare satisfaction levels and kinesiographic data, respectively. Use of DA improved the overall level of patient satisfaction (p<0.001). The kinesiographic recordings revealed a significant increase (1.7 mm) in vertical mandible movements (p<0.001) during chewing and a lower (0.3 mm) vertical intrusion of the maxillary complete dentures (p=0.002) during chewing after using the DA. Use of DA in complete denture wearers improved the patients' satisfaction and altered mandible movements, with increases in vertical movements during chewing and less intrusion of maxillary complete dentures.

Crossover clinical trial of different methods of removing a denture adhesive and the influence on the oral microbiota

“…demonstrated the placement of the DA in the maxillary and mandibular dentures to the participants according to the strip method. 24 Three 1-cm strips were applied to the frontal, right, and left middle region of the posterior segments of the dentures.…”

Mandibular kinesiographic pattern of women with chronic TMD after management with educational and self-care therapies: A double-blind, randomized clinical trial

“…This instrument was connected to a computerized system that recorded, displayed, and measured the spatial coordinates of movements in the vertical, anteroposterior, and lateral axes, at 0.1-mm accuracy. 26,34 Two tracing modes (scans) were selected for recordings: scan 1 recorded mandibular movement limits during maximum mouth opening, and scan 8 recorded mandibular movements during habitual mastication. For reliable registration, participants were asked to sit upright in a dental chair with the Frankfort plane parallel to the horizontal plane.…”

Utilization of Denture Adhesives and the Factors Associated with its Use: A Cross-Sectional Survey

“…Such use also aids in psychological satisfaction, thus improving the quality of life [15]. Denture adhesives improved well-tting denture stability [16], mastication [17], patient satisfaction [18], mandibular movement during chewing [18], and maximum bite force until denture dislodgement [19,20]. Experts also use denture adhesives in the clinical process when making dentures, particularly in study base xation, bite registration, and improvement of the accuracy of denture try-ins [21].…”
