“…There are numerous techniques for the final impressions making in the edentulous arches. [43][44][45][46][47] This clinical situation was complex because the patient had been wearing the existing complete dentures for the last 15 years and the residual alveolar ridges in the mandible were excessively reabsorbed and atrophied. Due to the short height of the ridge, it was decided to make the conventional final impression following the functional impression technique using her current complete dentures.…”

CAD/CAM complete dentures have shown to improve the fit and material strength than conventionally fabricated dentures, however there are no clinical protocols described for extreme residual ridge resorption. This report describes a combined workflow of conventional and novel techniques for CAD/CAM complete dentures fabrication for atrophic alveolar ridges. Key Clinical Message Extreme residual ridge resorption is a challenging clinical situation for the fabrication of complete dental prostheses and this clinical report demonstrates a CAD/CAM workflow solving this complicated situation.

“…Although there is not a large number of studies comparing the one‐ and two‐step methods, two systematic reviews suggested that the two‐step impression procedure is not mandatory for achieving clinical success considering both denture quality and patients' perception of treatment, and the use of simpler and less costly methods may be sufficient to serve the needs of the majority of patients . A recent Cochrane review by Jayaraman et al reported that most of the randomised clinical trials on this topic were judged as having high risk of bias and concluded that “there is no clear evidence that one technique or material has a substantial advantage over another for making complete dentures and removable partial dentures” …”

“…Cochrane review by Jayaraman et al 35 reported that most of the randomised clinical trials on this topic were judged as having high risk of bias and concluded that "there is no clear evidence that one technique or material has a substantial advantage over another for making complete dentures and removable partial dentures". 35 Considering that there is no robust evidence that supports a generally recommendable protocol for complete denture impression in prosthodontic teaching and clinical practice, 7 the alternative protocol proposed in our study may combine the potential advantages of the two methods, including the simplification of the one-step procedure and the alleged higher quality of the reproduction of the denture-supporting area that is likely to be achieved in the two-step procedure.…”

Effectiveness of a simplified method for final impression in complete denture treatment: A pragmatic clinical trial

2019

Purpose This study aimed to compare two methods for final impression during the fabrication of complete dentures: a traditional method using custom trays (T‐group) and a simplified method using the trial denture baseplate (S‐group). Methods A pragmatic clinical trial was conducted among edentulous individuals referred for conventional denture treatment. A consecutive sample of edentulous patients was assigned to two groups by cluster randomisation according to the final impression strategy, 30 in the T‐group and 38 in the S‐group. In the T‐group, an auto‐polymerising acrylic resin custom tray was used for impression; in the S‐group, the final impression was performed using the try‐in dentures. For both groups, zinc oxide eugenol paste was used as the impression material. The quality of the dentures was assessed using two rating scales (Functional Assessment of the Dentures and Kapur method). Moreover, clinical time for denture fabrication, number of post‐insertion appointments for adjustments, patient satisfaction and post‐treatment oral health‐related quality of life impacts were also assessed. Results There were no significant differences between groups regarding prosthodontic and patient‐reported outcomes. The S‐group demanded less clinical time (P = 0.002), with a 23.3% mean reduction in clinical time (P = 0.002) and lower number of appointments until the delivery of the dentures (S‐group = 4.18 vs T‐group = 5.0; P = 0.001). Conclusions This study showed that the alternative method for final impression is less time‐consuming and has similar clinical outcomes when compared to the traditional final impression method. Findings suggest that this alternative may be considered when efficiency is a critical issue in healthcare services.

“…Eugenol, in combination with zinc oxide (ZOE), is one of the most common materials used as a root canal sealer in endodontics [1][2][3][4][5], as well as a pulp sedative in cases of pulpotomies [6][7][8][9] and an impression material for edentulous patients [10][11][12][13]. In restorative dentistry, ZOE cements are frequently applied as temporary materials during indirect restorations [14].…”

Determining the Effects of Eugenol on the Bond Strength of Resin-Based Restorative Materials to Dentin: A Meta-Analysis of the Literature

et al. 2020

The aim of this study was to determine whether the residual presence of eugenol in coronal dentin may compromise the bond strength of resin-based restorative materials. A search was performed on MEDLINE/Pubmed, Scopus, and by hand search for relevant papers. No restriction was applied for language and publication date. The studies selected for analysis tested specimens with reduced size (micro-shear bond strength (µSBS) and micro-tensile bond strength (µTBS)) of adhesive systems and resin-based restorative materials applied to coronary dentin “contaminated” with eugenol-based materials. The search provided 335 articles, but only 10 studies met the inclusion criteria. The pooled global analysis showed a significant influence of eugenol, as it negatively influenced the bond strength of resin-based restorations (5.79 (3.31–8.28) MPa, p < 0.00001). The subgroup analyses for conventional etch-and-rinse (p = 0.003) and self-etch (p < 0.0004) adhesive systems, as well as for µSBS (p = 0.01) and µTBS (p < 0.0001), showed a negative influence of eugenol on the bond strength. Data were statistically heterogeneous. However, it was possible to observe that eugenol could negatively affect the bonding of resin-based restorative materials to dentin. Further evidence is necessary in order to acquire more accurate information about this issue and confirm that the residual presence of eugenol in dentin compromises the bond strength of resin-based materials.
