CAD/CAM produces Dentures with improved fit
Clinical Oral Investigations, 2018Co-Authors: Otto Steinmassl, Herbert Dumfahrt, Ingrid Grunert, Patriciaanca SteinmasslAbstract:Objectives Resin polymerisation shrinkage reduces the congruence of the denture base with denture-bearing tissues and thereby decreases the retention of conventionally fabricated Dentures. CAD/CAM denture manufacturing is a subtractive process, and polymerisation shrinkage is not an issue anymore. Therefore, CAD/CAM Dentures are assumed to show a higher denture base congruence than conventionally fabricated Dentures. It has been the aim of this study to test this hypothesis. Materials and methods CAD/CAM Dentures provided by four different manufacturers (AvaDent, Merz Dental, Whole You, Wieland/Ivoclar) were generated from ten different master casts. Ten conventional Dentures (pack and press, long-term heat polymerisation) made from the same master casts served as control group. The master casts and all denture bases were scanned and matched digitally. The absolute incongruences were measured using a 2-mm mesh. Results Conventionally fabricated Dentures showed a mean deviation of 0.105 mm, SD = 0.019 from the master cast. All CAD/CAM Dentures showed lower mean incongruences. From all CAD/CAM Dentures, AvaDent Digital Dentures showed the highest congruence with the master cast surface with a mean deviation of 0.058 mm, SD = 0.005. Wieland Digital Dentures showed a mean deviation of 0.068 mm, SD = 0.005, Whole You Nexteeth prostheses showed a mean deviation of 0.074 mm, SD = 0.011 and Baltic Denture System prostheses showed a mean deviation of 0.086 mm, SD = 0.012. Conclusions CAD/CAM produces Dentures with better fit than conventional Dentures. Clinical Relevance The present study explains the clinically observed enhanced retention and lower traumatic ulcer-frequency in CAD/CAM Dentures.

satisfaction in complete denture wearers with and without adhesives a randomized crossover double blind clinical trial
Journal of Clinical and Experimental Dentistry, 2018Co-Authors: Carlos Torressanchez, Vanessa Montoyasalazar, Daniel Torreslagares, Joseluis Gutierrezperez, Emilio JimenezcastellanosAbstract:Background The purpose of this study was to compare the satisfaction of patients regarding retention, stability and accumulation of particles with a randomized, double-blind crossed method in users with complete Dentures with and without adhesive. Material and Methods Seventeen edentulous individuals were randomized and received new upper and lower complete Dentures. After a period of adaptation, they participated in some masticatory tests and clinical revisions, after use the protheses with and without the use of two denture adhesives: Adhesive A (Fittydent, Fittydent International GmbH) and adhesive B (Corega, GlaxoSmithKline) at 0, 7 and 14 days. Satisfaction was measured immediately after each test through a survey using a VAS scale (0-10) and data were analyzed with McNemar's test with Bonferroni correction. Results The results showed significant differences (p<.01) between the study groups with adhesive A - B and the group without adhesive, but no significant differences were found between the two stickers for any of the variables studied. Conclusions Complete denture adhesives significantly improved the satisfaction of patients because a better retention, stability and less accumulation of particles of the food substitute between the denture and the mucosa is obtained compared with non-use of complete denture adhesives. Key words:Complete Dentures, patient satisfaction, denture adhesives, clinical trials.
