ObjectivesResin 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 methodsCAD/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.ResultsConventionally 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.ConclusionsCAD/CAM produces dentures with better fit than conventional dentures.Clinical RelevanceThe present study explains the clinically observed enhanced retention and lower traumatic ulcer-frequency in CAD/CAM dentures.

Mandibular implant overdentures increase satisfaction and the quality of life of edentulous individuals. Long-term aftercare and costs may depend on the type of overdentures. One hundred and ten individuals received one of 3 types of implant-retained overdentures, randomly assigned, and were evaluated with respect to aftercare and costs. The follow-up time was 8 years, with only seven drop-outs. No significant differences (Kruskal-Wallis test) were observed for direct costs of aftercare (p = 0.94). The initial costs constituted 75% of the total costs and were significantly higher in the group with a bar on 4 implants, compared with the group with a bar on 2 implants and the group with ball attachments on 2 implants (p = 0.018). The last group needed a significantly higher number of prosthodontist-patient aftercare contacts, mostly for re-adjustment of the retentive system. It can be concluded that an overdenture with a bar on 2 implants might be the most efficient in the long term.

One of the most common oral diseases affecting people wearing dentures is chronic atrophic candidiasis or denture stomatitis (DS). The aim of the paper is to provide an update on the pathogenesis, presentation, and management of DS in general dental practice settings. A comprehensive review of the literature published in the last ten years was undertaken using multiple databases, including PubMed via MEDLINE, EMBASE, and Scopus. The eligible articles were analyzed to identify evidence-based strategies for the management of DS. Despite its multifactorial nature, the leading cause of DS is the development of oral Candida albicans biofilm, which is facilitated by poor oral and denture hygiene, long-term denture wear, ill-fitting dentures, and the porosity of the acrylic resin in the dentures. DS affects between 17 and 75% of the population wearing dentures, with a slight predominance in elderly females. The mucosal denture surfaces and posterior tongue are the common sites of DS, and the affected areas exhibit erythema, the swelling of the palatal mucosa and edema. Oral and denture hygiene protocols, adjusting or re-fabricating poorly adapting dentures, smoking cessation, avoiding nocturnal denture wear, and the administration of topical or systemic antifungals are the mainstay of management. Alternate treatments such as microwave disinfection, phytomedicine, photodynamic therapy, and incorporation of antifungals and nanoparticles into denture resins are being evaluated for the treatment of DS but require further evidence before routine use in clinical practice. In summary, DS is the most common oral inflammatory lesion experienced by denture wearers. Most patients with DS can be managed in general dental practice settings. Effective management by general dental practitioners may be supported by a thorough understanding of the pathogenesis, the recognition of the clinical presentation, and an awareness of contemporary treatment strategies.

Background The establishment of good facial esthetics is one of the main objectives of complete denture construction. Unfortunately, it may be the caused issue for patients having a prominent premaxilla due to excessive lip support by the labial flange of the maxillary denture. Open-face dentures (OFD) may suggest suitable prosthetic management for these patients. However, clinical evidence regarding the efficiency of OFD is scarce. Methods A total of 38 completely edentulous participants having prominent premaxilla and skeletal class I Angle’s classification were enrolled in this study. Each participant received a mandibular complete denture and 2 opposing maxillary dentures; conventional (CD) and open-face (OFD). On the day of denture insertion, the participants were divided into 2 groups; CD-OFD and OFD-CD where CD-OFD group was instructed to use the mandibular denture and the maxillary CD for 3 months and then to use the maxillary OFD for another 3 months after a wash-out period of 2 weeks. While group OFD-CD was instructed to use the mandibular denture and the maxillary OFD for 3 months then to use the maxillary CD for another 3 months after a wash-out period of 2 weeks. The dislodging force of the maxillary dentures was evaluated using the universal testing machine and the patient perception of retention, esthetics, and comfort was evaluated using the Visual Analogue Scale (VAS). Evaluation was carried out 1 day, 1 month, and 3 months after denture insertion. The Student t-test was used to compare the 2 maxillary dentures and the intervals for each denture were compared by using the ANOVA test with repeated measures followed by a Post Hoc test (adjusted Bonferroni) for pairwise comparison. Results The significance of the obtained results was judged at the 5% level ( P value). The dislodging force and patient perception of retention did not show significant differences between the 2 dentures, while the perception of esthetics showed significant differences throughout the follow-up period. Perception of comfort showed an insignificant difference only at the 3-month interval. Conclusions Open-face maxillary dentures can be a suitable alternative for patients with prominent premaxilla to achieve satisfactory retention, aesthetics, and comfort.

Background Artificial teeth replicate the appearance of natural teeth and restore proper alignment, oral function, and speech. Over the years, dental materials and prosthetic design advancements have transformed the creation and effectiveness of complete denture teeth. This evolution showcases a continued commitment to developing materials and methods that enhance the comfort, functionality, and visual appeal for patients without teeth. This study evaluated and compared patient satisfaction and oral health-related quality of life (OHRQL) between prefabricated and computer-aided design and computer-aided manufacturing (CAD-CAM) milled acrylic resin denture teeth. Materials and methods This crossover clinical study included 10 completely edentulous patients rehabilitated with complete dentures (CDs). Two types of acrylic resin teeth were used: prefabricated and CAD-CAM-milled artificial teeth. Crossover design is a research method that minimizes variability among participants by assessing the impact of various treatments on the same individual. This methodological approach facilitates the identification and measurement of the treatment effects. Following six months of complete denture wear, patient satisfaction and oral health-related quality of life were evaluated using the Visual Analogue Scale (VAS) and the Oral Health Impact Profile (OHIP-EDENT-19). Statistical analysis was conducted using the Wilcoxon signed-rank test in SPSS software, with statistical significance established at P  < 0.05. Results There was no statistical difference between the groups in the total VAS scores and items, except for chewing efficiency, with a P-value of 0.035, where CAD-CAM milled resin teeth had statistically higher scores. In contrast, prefabricated teeth had a statistically higher aesthetic score ( p  = 0.033). Regarding OHIP-EDENT-19, many items showed no statistical differences between the two groups, except for functional limitations and difficulty chewing, which had a P-value of 0.05 and were statistically higher in prefabricated teeth. In contrast, psychological discomfort ( P  = 0.034) and social disability ( P  = 0.046) had significantly higher scores for the CAD-CAM milled teeth. Conclusion This study suggests that prefabricated and CAD-CAM milled resin teeth are viable treatment options for complete dentures. Prefabricated teeth are advisable when aesthetics is the patient’s primary concern. Conversely, CAD-CAM milled teeth are preferable when chewing efficiency is the primary concern.

Objectives Traditional complete denture (CD) design and fabrication techniques need several clinical and laboratory steps. To improve the qualities of denture base material and get rid of all the problems that come with the conventional fabrication process, novel production methods were approved. In the field of denture manufacture, new materials and computer-aided technology have been explored as potential solutions. So, this study aimed to investigate the effect of two different digital construction techniques of implant-assisted overdentures on peri-implant and posterior mandibular bone resorptions by CBCT. Materials and methods Twenty patients who received mandibular overdenture constructed by different construction techniques were classified equally and randomly into two groups ( n  = 10 per group): Group M : received milled mandibular overdenture opposed by maxillary complete denture. Group P : received 3D-printed mandibular overdenture opposed by maxillary complete denture. Peri-implant bone loss and posterior ridge resorption were assessed at baseline (T0), at 1 year(T1), and 3 years(T3) by superimposition of pre and post-treatment CBCT.The Shapiro-Wilk test was used to access data that was not normally distributed. Two distinct groups were compared using the Mann-Whitney test. The Wilcoxon signed-rank test was used to compare paired groups. Results Regarding vertical bone loss(VBL), Group P recorded higher VBL in comparison to Group M, where the mean was 0.57 ± 0.13, and 0.52 ± 0.12respectively, at T1 and 0.66 ± 0.11, 0.60 ± 0.12 at T3. There was a statistically significant difference at different times of evaluation within the groups where ( P  < 0.001). Regarding posterior ridge resorption(PRR), Group P recorded higher PRR in comparison to Group M, where the mean was 381 ± 18.5, 333 ± 17.2 respectively at T1and 533 ± 24.9, 478.5 ± 12.3 at T3. There was a statistically significant difference at different times of evaluation within the groups where ( P  = 0.005). Conclusion Regarding the preservation of peri-implant alveolar bone and posterior ridge bone, milled implant-assisted complete overdentures may have more favorable clinical outcomes compared to 3D printed implant overdentures in the digitally constructed mandibular overdenture bases retained by two implants. Clinical relevance Both milled and 3D printed implant overdenture impression techniques can be used for the construction of CAD/CAM-implant retained overdenture base. However, in regarding the peri-implant alveolar bone and posterior ridge bone resorption, milled implant-assisted complete overdentures may have more favorable clinical outcomes compared to 3D printed implant overdentures retained by two implants.
